Majority of the research in green organic chemistry chemicals are some of the important starting materials for greater number of major chemical industries. The production of organic chemicals has raw materials (or) reagents for other application is major sector of manufacturing polymers, pharmaceuticals, pesticides, paints, artificial fibers, food additives etc. organic synthesis on a large scale compound to the labratory scale, involves the use of energy, basic chemical ingredients from the petro chemical sectors, catalyst and after the end of the reaction, seperation, purification, storage, packing distribution etc. During these processes there are many problems of health and safety for workers in addition to the environmental problems caused there by use and deposition as waste. Green chemistry with its 12 principles would like to see changes in conventional way that were used for decades to make synthetic organic chemical and the use of less toxic starting materials. Green chemistry would like to increase the efficiency of synthetic methods, to use less toxic solvents, reduce the stage of synthetic routes and minimize waste as far as practically possible. In this way, organic synthesis will be part of the effort for sustainable development Green chemistry is also interested for research and alternatives innovations on many practical aspects of organic synthesis in the university and research labaratory of institutions. By changing the methodologies of organic synthesis, health and safety will be advanced in the small scale laboratory level but also will be extended to the industrial large scale production a process through new techniques. The three key developments in green chemistry include the use of super critical carbondioxide as green solvent, aqueous hydrogen peroxide as an oxidising agent and use of hydrogen in asymmetric synthesis. It also focuses on replacing traditional methods of heating with that of modern methods of heating like microwaves traditions, so that carbon foot print should reduces as far as possible. Another beneficiary of this green chemistry is that it will reduce environmental pollution through the use of less toxic reagents, minimizing of waste and more bio-degradable biproducts. In this present paper some of the basic principles, approaches, and early achievements of green chemistry has a branch of chemistry that studies the laws of passing of chemical reactions is also considered, with the summarization of green chemistry principles. A discussion about E-factor, old and new synthesis of ibuprofen, microwave techniques, and some of the recent advancements also considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy" title="energy">energy</a>, <a href="https://publications.waset.org/abstracts/search?q=e-factor" title=" e-factor"> e-factor</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20foot%20print" title=" carbon foot print"> carbon foot print</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-wave" title=" micro-wave"> micro-wave</a>, <a href="https://publications.waset.org/abstracts/search?q=sono-chemistry" title=" sono-chemistry"> sono-chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=advancement" title=" advancement"> advancement</a> </p> <a href="https://publications.waset.org/abstracts/18830/green-organic-chemistry-a-new-paradigm-in-pharmaceutical-sciences" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18830.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">306</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2694</span> Preparation of MgO Nanoparticles by Green Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Sabbaghan">Maryam Sabbaghan</a>, <a href="https://publications.waset.org/abstracts/search?q=Pegah%20Sofalgar"> Pegah Sofalgar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the past few decades, a significant amount of research activities in the chemical community has been directed towards green synthesis.

The reaction entails the condensation of aryl glyoxals and 4-hydroxyxoumarin in the presence of catalytic amount of zinc oxide nanoparticles (ZnO NPs) as recyclable catalyst in aqueous media. High product yields and use of clean conditions are important factors of green chemistry.Part of our continued interest to achieve high atom economic reactions by the use safe catalysts. The reaction mixture was refluxed with catalytic amount (3 mol%) of zinc oxide nanoparticles.Reducing the amount of toxic waste and byproducts arising from chemical reactions is an important issue in the context of green chemistry. In comparison with commonly organic solvents, the aqueous media is cheaper and more environmentally friendly. Avoiding the use of organic solvents is an important way to prevent waste in chemical processes. In the context of green and sustainable chemistry, one ofthe most promising approaches is the use of water as the reaction media. In recent years, there has been increasing recognition that water is an attractive media for manyorganic reactions. Using water continues to attract wide attention among synthetic chemists in the design of new synthetic methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide" title="zinc oxide">zinc oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=dicoumarol" title=" dicoumarol"> dicoumarol</a>, <a href="https://publications.waset.org/abstracts/search?q=aryl%20glyoxal" title=" aryl glyoxal"> aryl glyoxal</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry" title=" green chemistry"> green chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=catalyst" title=" catalyst"> catalyst</a> </p> <a href="https://publications.waset.org/abstracts/36357/nano-zinc-oxide-a-powerful-and-recyclable-catalyst-for-chemospecific-synthesis-of-dicoumarols-based-on-aryl-glyoxals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36357.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">354</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2692</span> Water-Bentonite Interaction of Green Pellets through Micro-Structural Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Satyananda%20Patra">Satyananda Patra</a>, <a href="https://publications.waset.org/abstracts/search?q=Venugopal%20Rayasam"> Venugopal Rayasam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The quality of pellets produced is affected by quality and type of green pellets, amount of addition of binders and fluxing agents along with the provided firing conditions. The green pellet quality depends upon chemistry, mineralogy and granulometry of fines used for pellet making, the feed size, its moisture content and porosity. During firing of green pellets, ingredients present within reacts to form different phases and microstructure. So in turn, physical and metallurgical properties of pellets are influenced by amount and type of binder and flux addition, induration time and temperature. During iron making process, the metallurgical properties of fired pellets are decided by the type and amount of these phases and their chemistry. Green pelletizing and induration studies have been already carried out with magnetite and hematite ore fines but for Indian iron ores of high alumina content showing different pelletizing characters, these studies cannot be directly interpreted. The main objective of proposed research work is to understand the green pelletizing process and determine the water bentonite interaction at different levels. Swelling behavior of bentonite and microstructure of the green pellet are investigated. Conversion of iron ore fines into pellets, the key raw material and process variables that influence the pellet quality needs to be identified and a correlation should be established between them. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iron%20ore" title="iron ore">iron ore</a>, <a href="https://publications.waset.org/abstracts/search?q=pelletization" title=" pelletization"> pelletization</a>, <a href="https://publications.waset.org/abstracts/search?q=binders" title=" binders"> binders</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20pellets" title=" green pellets"> green pellets</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a> </p> <a href="https://publications.waset.org/abstracts/71905/water-bentonite-interaction-of-green-pellets-through-micro-structural-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71905.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">313</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2691</span> Renewable and Functional Biopolymers Using Green Chemistry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aman%20Ullah">Aman Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of renewable resources in supplementing and/or replacing traditional petrochemical products, through green chemistry, is becoming the focus of research. The utilization of oils can play a primitive role towards sustainable development due to their large scale availability, built-in-functionality, biodegradability and no net CO2 production. Microwaves, being clean, green and environmentally friendly, are emerging as an alternative source for product development. Solvent free conversion of fatty acid methyl esters (FAME's) derived from canola oil and waste cooking oil under microwave irradiation demonstrated dramatically enhanced rates. The microwave-assisted reactions lead to the most valuable terminal olefins with enhanced yields, purities and dramatic shortening of reaction times. Various monomers/chemicals were prepared in high yield in very short time. The complete conversions were observed at temperatures as low as 40 ºC within less than five minutes. The products were characterized by GC-MS, GC-FID and NMR. The monomers were separated and polymerized into different polymers including biopolyesthers, biopolyesters, biopolyamides and biopolyolefins. The polymers were characterized in details for their structural, thermal, mechanical and viscoelastic properties. The ability for complete conversion of oils under solvent free conditions and synthesis of different biopolymers is undoubtedly an attractive concept from both an academic and an industrial point of view. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=monomers" title="monomers">monomers</a>, <a href="https://publications.waset.org/abstracts/search?q=biopolymers" title=" biopolymers"> biopolymers</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry" title=" green chemistry"> green chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=bioplastics" title=" bioplastics"> bioplastics</a>, <a href="https://publications.waset.org/abstracts/search?q=biomaterials" title=" biomaterials"> biomaterials</a> </p> <a href="https://publications.waset.org/abstracts/152656/renewable-and-functional-biopolymers-using-green-chemistry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152656.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2690</span> Green Synthesis of Nicotine Analogues via Cycloaddition Reactions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20Fry%C5%BAlewicz">Agnieszka Fryźlewicz</a>, <a href="https://publications.waset.org/abstracts/search?q=Jowita%20Kras"> Jowita Kras</a>, <a href="https://publications.waset.org/abstracts/search?q=Miko%C5%82aj%20Sadowski"> Mikołaj Sadowski</a>, <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20%C5%81apczuk-Krygier"> Agnieszka Łapczuk-Krygier</a>, <a href="https://publications.waset.org/abstracts/search?q=Agnieszka%20K%C4%85cka-Zych%20Radomir%20Jasi%C5%84ski"> Agnieszka Kącka-Zych Radomir Jasiński</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nicotines are a group of compounds containing conjugated pyridine and pyrrolidine molecular segments.

Compared to the other traditional green metrics (E-factor, Atom economy and the process profile), the eco scale is the optimum choice to assess the environmental impact of the analytical procedures used for pharmaceuticals analysis. For analytical methodologies, Eco-Scale is calculated by allotting penalty points to any factor of the used analytical procedure which disagree and not match with the model green analysis, where the perfect green analysis has its Eco-Scale value of 100. In this work, calculation and comparison of the Eco-Scale for some of the reported green analytical methods was done, to accentuate their greening potentials. Where the different scores can reveal how green the method is, compared to the ideal value. The study emphasizes that greenness measurement is not only about the waste quantity determination but also dictates a holistic scheme, considering all factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eco%20scale" title="eco scale">eco scale</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20analysis" title=" green analysis"> green analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=environmentally%20friendly" title=" environmentally friendly"> environmentally friendly</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceuticals%20analysis" title=" pharmaceuticals analysis"> pharmaceuticals analysis</a> </p> <a href="https://publications.waset.org/abstracts/21750/eco-scale-a-tool-for-assessing-the-greenness-of-pharmaceuticals-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21750.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">438</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2688</span> Integration of Entrepreneurial Mindset Learning in Green Chemistry and Processes Course</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tsvetanka%20Filipova">Tsvetanka Filipova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Entrepreneurial mindset learning (EML) is the combined process of instilling curiosity and invention, developing insight and value creation while building on other active pedagogy, such as project-based learning (PBL). It is essential to introduce students to chemistry and chemical engineering entrepreneurship in a manner that gives a holistic approach by first educating students on diverse entrepreneurial skills and then providing an opportunity to build their innovation. Chemistry and chemical engineering students have an opportunity to be engaged in an entrepreneurial class project in the Green Chemistry and Processes course at South Dakota Mines. The course provides future chemists and chemical engineers with the knowledge and skills required to enable them to design materials and processes in an environmentally benign way. This paper presents findings from implementing an open-ended design project in the Green Chemistry and Processes course. The goal of this team project is to have student teams design sustainable polymer materials to fulfill a need and/or opportunity related to a fictitious aerospace company that satisfies technical, safety, environmental, regulatory, economic, and social needs. Each student team is considered a start-up company charged with the task of designing sustainable polymer materials for aerospace applications. Through their work on the project, students utilize systems and entrepreneurial thinking in selecting their design project, being aware of the existent technologies (literature and patent search) and users and clients (connections), determining the goals and motivations (creating value), and what need or problem they are trying to address (curiosity). The project draws systems boundaries by focusing on student exploration of feedstocks to end-of-life of polymeric materials and products. Additional subtopics to explore are green processes for syntheses, green engineering for process design, and the economics of sustainable polymers designed for circularity. Project deliverables are team project reports and project presentations to a panel of industry, chemistry, and engineering professionals. Project deliverables are team project reports and project presentations to a panel of industry, chemistry, and engineering professionals. The impact of the entrepreneurial mindset project is evaluated through a student survey at the end of the semester. It has been found that the Innovative Solution project was excellent in promoting student curiosity, creativity, critical and systems thinking and teamwork. The results of this study suggest that incorporating EML positively impacted students’ professional skill development, their ability to understand and appreciate the socio-technical context of chemistry and engineering, and the cultivation of an entrepreneurial mindset to discover, evaluate and exploit opportunities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curriculum" title="curriculum">curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurial%20mindset%20learning" title=" entrepreneurial mindset learning"> entrepreneurial mindset learning</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry%20and%20engineering" title=" green chemistry and engineering"> green chemistry and engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=systems%20thinking" title=" systems thinking"> systems thinking</a> </p> <a href="https://publications.waset.org/abstracts/195380/integration-of-entrepreneurial-mindset-learning-in-green-chemistry-and-processes-course" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/195380.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2687</span> Green Chemical Processing in the Teaching Laboratory: A Convenient Solvent Free Microwave Extraction of Natural Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Amine%20Ferhat">Mohamed Amine Ferhat</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Nadjib%20Bouhatem"> Mohamed Nadjib Bouhatem</a>, <a href="https://publications.waset.org/abstracts/search?q=Farid%20Chemat"> Farid Chemat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the principal aims of sustainable and green processing development remains the dissemination and teaching of green chemistry to both developed and developing nations.

Furthermore, tetrazoles have application in material sciences as explosives, rocket propellants, and in information recording systems. In addition to this, they have a wide range of application in coordination chemistry as a ligand. Deep eutectic solvents (DES) have emerged over the current decade as a novel class of green reaction media and applied in various fields of sciences because of their unique physical and chemical properties similar to the ionic liquids such as low vapor pressure, non-volatility, high thermal stability and recyclability. In addition, the reactants of DES are cheaply available, low-toxic, and biodegradable, which makes them predominantly required for large-scale applications effectively in industrial production. Herein we report the [2+3] cycloaddition reaction of organic nitriles with sodium azide affords the corresponding 5-substituted 1H-tetrazoles in six different types of choline chloride based deep eutectic solvents under mild reaction condition. Choline chloride: ZnCl2 (1:2) showed the best results for the synthesis of 5-substituted 1 H-tetrazoles. This method reduces the disadvantages such as: the use of toxic metals and expensive reagents, drastic reaction conditions and the presence of dangerous hydrazoic acid. The approach provides environment-friendly, short reaction times, good to excellent yields; safe process and simple workup make this method an attractive and useful contribution to present green organic synthesis of 5-substituted-1H-tetrazoles. All synthesized compounds were characterized by IR, 1H NMR, 13C NMR and Mass spectroscopy. DES can be recovered and reused three times with very little loss in activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=click%20chemistry" title="click chemistry">click chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=choline%20chloride" title=" choline chloride"> choline chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry" title=" green chemistry"> green chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20eutectic%20solvent" title=" deep eutectic solvent"> deep eutectic solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=tetrazoles" title=" tetrazoles"> tetrazoles</a> </p> <a href="https://publications.waset.org/abstracts/73046/synthesis-of-5-substituted-1h-tetrazoles-in-deep-eutectic-solvent" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73046.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">231</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2683</span> Quest for an Efficient Green Multifunctional Agent for the Synthesis of Metal Nanoparticles with Highly Specified Structural Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niharul%20Alam">Niharul Alam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The development of energy efficient, economic and eco-friendly synthetic protocols for metal nanoparticles (NPs) with tailor-made structural properties and biocompatibility is a highly cherished goal for researchers working in the field of nanoscience and nanotechnology. In this context, green chemistry is highly relevant and the 12 principles of Green Chemistry can be explored to develop such synthetic protocols which are practically implementable. One of the most promising green chemical synthetic methods which can serve the purpose is biogenic synthetic protocol, which utilizes non-toxic multifunctional reactants derived from natural, biological sources ranging from unicellular organisms to higher plants that are often characterized as “medicinal plants”. Over the past few years, a plethora of medicinal plants have been explored as the source of this kind of multifunctional green chemical agents. In this presentation, we focus on the syntheses of stable monometallic Au and Ag NPs and also bimetallic Au/Ag alloy NPs with highly efficient catalytic property using aqueous extract of leaves of Indian Curry leaf plat (Murraya koenigii Spreng.; Fam. Rutaceae) as green multifunctional agents which is extensively used in Indian traditional medicine and cuisine. We have also studied the interaction between the synthesized metal NPs and surface-adsorbed fluorescent moieties, quercetin and quercetin glycoside which are its chemical constituents. This helped us to understand the surface property of the metal NPs synthesized by this plant based biogenic route and to predict a plausible mechanistic pathway which may help in fine-tuning green chemical methods for the controlled synthesis of various metal NPs in future. We observed that simple experimental parameters e.g. pH and temperature of the reaction medium, concentration of multifunctional agent and precursor metal ions play important role in the biogenic synthesis of Au NPs with finely tuned structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20multifunctional%20agent" title="green multifunctional agent">green multifunctional agent</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20nanoparticles" title=" metal nanoparticles"> metal nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=biogenic%20synthesis" title=" biogenic synthesis"> biogenic synthesis</a> </p> <a href="https://publications.waset.org/abstracts/14694/quest-for-an-efficient-green-multifunctional-agent-for-the-synthesis-of-metal-nanoparticles-with-highly-specified-structural-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14694.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">431</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2682</span> Synthesis of Flavonoid Derivatives Precursors of Active Pharmaceutical Ingredients by Mechanical Chemistry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imen%20Abid">Imen Abid</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachel%20Calvet"> Rachel Calvet</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Baltas"> Michel Baltas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flavonoids are secondary metabolites that belong to a polyphenolic class, present in fruits and vegetables, playing a significant role in biological systems. The structural variations of these flavonoids are associated with many biological and pharmacological activities (antioxidant, anti-inflammatory, anticancer, antibacterial, antifungal, antiviral, and antimalarial). Given their importance in plants and health-promoting roles in humans, significant efforts have been devoted towards their isolation of flavonoids and chemical elaboration (organic synthesis). But with the increasing public concern over environmental degradation and future resources, it is of great importance for chemists to come up with different approaches, less hazardous to human health and the environment. Being employed in large amounts, the solvents used in organic synthesis are high on the list of environmental pollutants. To overcome these problems, our approach is to develop unconventional processes involving solvent-free conditions. The application of mechanical forces to solvent-free or solvent-less reaction mixtures through the use of ball mills offers many advantages over traditional solvent-based strategies. It is one of the unconventional activation methods, which makes it possible to overcome the use of solvents, in the context of green chemistry and more respectful of the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20synthesis" title="organic synthesis">organic synthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20chemistry" title=" green chemistry"> green chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=mecanochemistry" title=" mecanochemistry"> mecanochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceutical%20molecules" title=" pharmaceutical molecules"> pharmaceutical molecules</a> </p> <a href="https://publications.waset.org/abstracts/168281/synthesis-of-flavonoid-derivatives-precursors-of-active-pharmaceutical-ingredients-by-mechanical-chemistry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168281.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2681</span> Virtual Chemistry Laboratory as Pre-Lab Experiences: Stimulating Student's Prediction Skill</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yenni%20Kurniawati">Yenni Kurniawati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Students Prediction Skill in chemistry experiments is an important skill for pre-service chemistry students to stimulate students reflective thinking at each stage of many chemistry experiments, qualitatively and quantitatively.

This research focuses on synthesizing novel compounds from an all-natural Eucalyptus citriodora oil. Eight novel plasticizer compounds are synthesized and optimized using flow chemistry technology. A precursor to one novel compound can be synthesized from the lauric acid present in coconut oil. Key parameters, such as catalyst screening and loading, reaction time, temperature, residence time using flow chemistry techniques is investigated. The compounds are characterised using GC-MS, FT-IR, 1H and 13C-NMR techniques, X-ray crystallography. The efficiency of the compounds is compared to two commercial plasticizers, i.e. Dibutyl phthalate and Eastman 168. Several PVC-plasticized film formulations are produced using the bio-based novel compounds. Tensile strength, stress at fracture and percentage elongation are tested. The property of having increasing plasticizer percentage in the film formulations is investigated, ranging from 3, 6, 9 and 12%. The diastereoisomers of each compound are separated and formulated into PVC films, and differences in tensile strength are measured. Leaching tests, flexibility, and change in glass transition temperatures for PVC-plasticized films is recorded. Research objective includes using these novel compounds as a green bio-plasticizer alternative in plastic products for infants. The inhibitory effect of the compounds on six pathogens effecting infants are studied, namely; Escherichia coli, Staphylococcus aureus, Shigella sonnei, Pseudomonas putida, Salmonella choleraesuis and Klebsiella oxytoca. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-based%20compounds" title="bio-based compounds">bio-based compounds</a>, <a href="https://publications.waset.org/abstracts/search?q=plasticizer" title=" plasticizer"> plasticizer</a>, <a href="https://publications.waset.org/abstracts/search?q=tensile%20strength" title=" tensile strength"> tensile strength</a>, <a href="https://publications.waset.org/abstracts/search?q=microbiological%20inhibition" title=" microbiological inhibition "> microbiological inhibition </a>, <a href="https://publications.waset.org/abstracts/search?q=synthesis" title=" synthesis"> synthesis</a> </p> <a href="https://publications.waset.org/abstracts/79061/synthesis-and-characterisation-of-bio-based-acetals-derived-from-eucalyptus-oil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79061.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">186</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2679</span> Students’ Perception of Effort and Emotional Costs in Chemistry Courses</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guizella%20Rocabado">Guizella Rocabado</a>, <a href="https://publications.waset.org/abstracts/search?q=Cassidy%20Wilkes"> Cassidy Wilkes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is well known that chemistry is one of the most feared courses in college. Although many students enjoy learning about science, most of them perceive that chemistry is “too difficult”. These perceptions of chemistry result in many students not considering Science, Technology, Engineering, and Mathematics (STEM) majors because they require chemistry courses. Ultimately, these perceptions are also thought to be related to high attrition rates of students who begin STEM majors but do not persist. Students perceived costs of a chemistry class can be many, such as task effort, loss of valued alternatives, emotional, and others. These costs might be overcome by students’ interests and goals, yet the level of perceived costs might have a lasting impact on the students’ overall perception of chemistry and their desire to pursue chemistry and other STEM careers in the future. In this mixed methods study, we investigated task effort and emotional cost, as well as a mastery or performance goal orientation, and the impact these constructs may have on achievement in general chemistry classrooms. Utilizing cluster analysis as well as student interviews, we investigated students’ profiles of perceived cost and goal orientation as it relates to their final grades. Our results show that students who are well prepared for general chemistry, such as those who have taken chemistry in high school, display less negative perceived costs and thus believe they can master the material more fully. Other interesting results have also emerged from this research, which has the potential to have an impact on future instruction of these courses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemistry%20education" title="chemistry education">chemistry education</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=affect" title=" affect"> affect</a>, <a href="https://publications.waset.org/abstracts/search?q=perceived%20costs" title=" perceived costs"> perceived costs</a>, <a href="https://publications.waset.org/abstracts/search?q=goal%20orientations" title=" goal orientations"> goal orientations</a> </p> <a href="https://publications.waset.org/abstracts/166587/students-perception-of-effort-and-emotional-costs-in-chemistry-courses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166587.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2678</span> Contextual Paper on Green Finance: Analysis of the Green Bonds Market</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dina%20H.%20Gabr">Dina H.

Coupled with adopting the Paris Agreement and the United Nations Sustainable Development Goals, Green finance became a vital tool in creating a pathway to sustainable development, as it connects the financial world with environmental and societal benefits. This paper provides a comprehensive review of the concepts and definitions of green finance and the importance of 'green' impact investments today. The core challenge in combating climate change is reducing and controlling Greenhouse gas emissions; therefore, this study explores the solutions green finance provides putting emphasis on the use of renewable energy, which is necessary for enhancing the transition to the green economy. With increasing attention to the concept of green finance, multiple forms of green investments and financial tools have come to fruition; the most prominent are green bonds. The rise of green bonds, a debt market to finance climate solutions, provide a promising mechanism for sustainable finance. Following the review, this paper compiles a comprehensive green bond dataset, presenting a statistical study of the evolution of the green bonds market from its first appearance in 2006 until 2021. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=GHG%20emissions" title=" GHG emissions"> GHG emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20bonds" title=" green bonds"> green bonds</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20finance" title=" green finance"> green finance</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20finance" title=" sustainable finance"> sustainable finance</a> </p> <a href="https://publications.waset.org/abstracts/149244/contextual-paper-on-green-finance-analysis-of-the-green-bonds-market" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149244.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">120</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2677</span> Agriroofs and Agriwalls: Applications of Food Production in Green Roofs and Green Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eman%20M.%20Elmazek">Eman M.

The idea takes great steps towards the future of sustainable design due to its many benefits. However, there are many barriers and constraints. Economical, structural, and knowledge barriers prevent the spread of the usage of green roofs and living walls. Understanding the benefits and expanding them will spread the idea. Benefits provided by these green spots interrupt and maintain the current urban cover. Food production is one of the benefits of green roofs. It can save money and energy spent in food transportation. The goal of this paper is to put a better understanding of implementing green systems. The paper aims to identify gains versus challenges facing the technology.

To design a product, there can be alternative options to design the detailed components to fulfill the same product requirement. In the design alternative cases, the components of the product can be designed with different materials and detailed specifications. If several design alternative cases are proposed, the different materials and specifications can affect the manufacturing processes. In this paper, a new concept for integrating green design and green manufacturing processes is presented. A green design can be determined based the manufacturing processes of the designed product by evaluating the green criteria including energy usage and environmental impact, in addition to the traditional criteria of manufacturing cost. With this concept, a mathematical model is developed to find the green design and the associated green manufacturing processes. In the mathematical model, the cost items include material cost, manufacturing cost, and green related cost. The green related cost items include energy cost and environmental cost. The objective is to find the decisions of green design and green manufacturing processes to achieve the minimized total cost. In practical applications, the decision-making can be made to select a good green design case and its green manufacturing processes. In this presentation, an example product is illustrated. It shows that the model is practical and useful for integrated evaluation of green design and green manufacturing processes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=supply%20chain%20management" title="supply chain management">supply chain management</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20supply%20chain" title=" green supply chain"> green supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20design" title=" green design"> green design</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20manufacturing" title=" green manufacturing"> green manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model"> mathematical model</a> </p> <a href="https://publications.waset.org/abstracts/10104/integrated-evaluation-of-green-design-and-green-manufacturing-processes-using-a-mathematical-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10104.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">807</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2675</span> Effect of Chemistry Museum Artifacts on Students’ Memory Enhancement and Interest in Radioactivity in Calabar Education Zone, Cross River State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hope%20Amba%20Neji">Hope Amba Neji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study adopted a quasi-experimental design.

The myriad of reasons to go Green has multiplied to the point that a developer that is building a ground-up or renovating/retrofitting a property has a plethora of choices to get to the green goal post. Sustainability not affects the bottom line but satisfies corporate mandates (ESG), consumer demand, market requirements, and the many laws dictating green building practices. The good news is that there are many paths a property owner can take to become green. The bad news is that there are many paths a property owner can take to become green, and they need to choose which direction to take. Certification of a building used to be the highest achievement in the Green building world. Now there are so many variables and laws with which a property owner must comply, and the legal analysis has mushroomed. Operation and Maintenance have also become one of the most important functions for a prudent Green Building owner. So adding to the “development/retrofit” parties involved in the sustainable building legal world, we now need to include all those people who keep the building green, and there are a lot of them! <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20building" title="green building">green building</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title=" sustainable development"> sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=legal%20issues" title=" legal issues"> legal issues</a>, <a href="https://publications.waset.org/abstracts/search?q=greenwashing" title=" greenwashing"> greenwashing</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20cleaning" title=" green cleaning"> green cleaning</a>, <a href="https://publications.waset.org/abstracts/search?q=compliance" title=" compliance"> compliance</a>, <a href="https://publications.waset.org/abstracts/search?q=ESQ" title=" ESQ"> ESQ</a> </p> <a href="https://publications.waset.org/abstracts/154541/sustainable-building-law-the-legal-issues-abound" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154541.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2673</span> Aryne Mediated, Transition-Metal Free Arylations of Quinolines for Medicinal and Materials Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rakesh%20Kumar">Rakesh Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shashi%20Janeoo"> Shashi Janeoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ankit%20Dhiman"> Ankit Dhiman</a>, <a href="https://publications.waset.org/abstracts/search?q=Siddharth%20Chopra"> Siddharth Chopra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Arynes are versatile reactive intermediates that offer broad opportunities in green organic synthesis. Arynes are potential aryl group surrogates for the transition metal-free environment friendly arylation reactions. Regioselective arylations of quinolines were achieved by the reactions of quinoline N-oxides with aryne intermediates generated in situ from the Kobayashi precursors. Various 2-substituted quinolines provided 3-arylated-2-substituted quinolines under ambient conditions. Acridine N-oxides also reacted well and provided unusual 4-arylacridines. Various fluorine containing 2,3-diarylquinaolines prepared using this approach were evaluated for antibacterial activity and two compounds inhibited the drug-resistant strains of S-aureus with a good selectivity index. Further, the 2,3-diarylquinolines as the potential optoelectronic materials were prepared by the aryne chemistry approach and their optical and electronic properties for such applications are under study. The aryne intermediates provide an effective Green Chemistry tool to achieve versatile arylated heteroarenes for diverse applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arynes" title="arynes">arynes</a>, <a href="https://publications.waset.org/abstracts/search?q=arylation" title=" arylation"> arylation</a>, <a href="https://publications.waset.org/abstracts/search?q=quinolines" title=" quinolines"> quinolines</a>, <a href="https://publications.waset.org/abstracts/search?q=acridines." title=" acridines."> acridines.</a> </p> <a href="https://publications.waset.org/abstracts/153651/aryne-mediated-transition-metal-free-arylations-of-quinolines-for-medicinal-and-materials-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153651.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2672</span> Using a GIS-Based Method for Green Infrastructure Accessibility of Different Socio-Economic Groups in Auckland, New Zealand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jing%20Ma">Jing Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Xindong%20An"> Xindong An</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Green infrastructure, the most important aspect of improving the quality of life, has been a crucial element of the liveability measurement.

As such, the need for ICT devices has increased, contributing to high electronic equipment acquisition and disposal. Hence, its use and disposal must be seen in light of environmental sustainability, i.e., in terms of green use and disposal. However, there are limited studies on green Use and Disposal framework to be used as guiding lens by organizations in developing countries. And this study endeavors to address that need taking one of the largest multinational ICT intensive company in the country. The design and development of this framework passed through several stages, initially factors affecting green use and disposal were identified after quantitative and qualitative data analysis then there were multiple brainstorming sessions for the design enhancement as participative modelling was employed. Given the difference in scope and magnitude of the challenges identified, the proposed framework approaches green use and disposal in four imperatives; strategically, tactically, operationally and through continuous improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title="energy efficiency">energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20disposal" title=" green disposal"> green disposal</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20ICT" title=" green ICT"> green ICT</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20use" title=" green use"> green use</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20use%20and%20disposal%20framework" title=" green use and disposal framework"> green use and disposal framework</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/123464/a-framework-for-green-use-and-disposal-of-information-communication-technology-devices" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123464.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">210</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2670</span> Analytic Hierarchy Process Method for Supplier Selection Considering Green Logistics: Case Study of Aluminum Production Sector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Erbiyik">H.

Hubs and links of main elements of green infrastructure have been identified from incorporating cadastral data of 967,502 parcels to 135 of land use maps using geographic information system. Network analyses were used to rank hubs and links of a green infrastructure map with applying a force-directed algorithm, weighted values, and binary relationships that has metrics of density, distance, and centrality.

They are considered to have lower toxicity than traditional pesticides. After almost a century of pesticides use, resistances to traditional insecticides are wide spread, while those to bioinsecticides have raised less attention, and resistance management is frequently neglected. This seems to be a crucial mistake since resistances have already occurred for many marketed biopesticides. With an eye to the future, we present here a selection of new natural occurring chemicals as potential bioinsecticides. The molecules were selected using a consolidated mathematical paradigm called molecular topology. Several QSAR equations were depicted and subsequently applied for the virtual screening of hundred thousands molecules of natural origin, which resulted in the selection of new potential bioinsecticides. The most innovative aspect of this work does not only reside in the importance of the identification of new molecules overcoming biopesticides’ resistances, but on the possibility to promote shared knowledge in the field of green chemistry through this unique in silico discipline named molecular topology. <p class="card-text"><strong>Keywords:</strong> <a
