Although laboratory studies showed that they can technically recover Li to 90%, challenges still remain in developing a sustainable process that can serve as a foundation for the lithium dependent low-carbon economy. There is a continuing quest for DLE technologies that do not need extensive pre-treatments, fewer materials, and have simplified extraction processes with high Li selectivity. Here, an overview of DLE technologies will be provided with an emphasis on the basic principles of the materials’ design for the development of membranes with nanochannels and nanopores with Li ion selectivity. We have used a variety of building blocks such as nano-clay, organic frameworks, Graphene/oxide, MXene, etc., to fabricate the membranes. Molecular dynamic simulation (MD) and density functional theory (DFT) were used to reveal new mechanisms by which high Li selectivity was obtained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium%20recovery" title="lithium recovery">lithium recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane" title=" membrane"> membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20selectivity" title=" lithium selectivity"> lithium selectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=decarbonization" title=" decarbonization"> decarbonization</a> </p> <a href="https://publications.waset.org/abstracts/149229/membranes-for-direct-lithium-extraction-dle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149229.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">112</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">4047</span> Cracking of Tar Analogue in N₂ Carrier Gas Using Non-Thermal Plasma Dielectric Barrier Discharge Reactor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Saleem">Faisal Saleem</a>, <a href="https://publications.waset.org/abstracts/search?q=Kui%20Zhang"> Kui Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Adam%20Harvey"> Adam Harvey</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The role of N₂ carrier gas towards the conversion of tar analogue was studied in a non-thermal plasma dielectric barrier discharge (DBD) reactor. The important parameters such as power (5-40W), residence time (1.41-4.23 s), concentration (20-82 g/Nm³), and temperature (Ambient-400°C) were explored. The present study demonstrated that plasma power and residence time played a key role in the decomposition of toluene, and almost complete removal of toluene was observed at 40w and 4.23 s. H₂ is obtained as a major gaseous product with a maximum selectivity of 40% along with some lighter hydrocarbons (5.5%). The removal efficiency of toluene slightly decreases with increasing the concentration of toluene from 20 g/Nm³ to 82 g/Nm³. The solid residue formation takes place inside the plasma reactor. The selectivity of LHC (lower hydrocarbons) increased up to 15% by increasing the temperature to 400°C. Introducing H₂ to the gas at elevated temperature opens up new reaction routes to raise the selectivity to lower hydrocarbons. The selectivity to methane reaches to 42% using 35% H₂ at 400°C and total selectivity of LHC increases to 57%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomass%20gasification%20tar" title="biomass gasification tar">biomass gasification tar</a>, <a href="https://publications.waset.org/abstracts/search?q=non-thermal%20plasma" title=" non-thermal plasma"> non-thermal plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20barrier%20discharge" title=" dielectric barrier discharge"> dielectric barrier discharge</a>, <a href="https://publications.waset.org/abstracts/search?q=residence%20time" title=" residence time"> residence time</a> </p> <a href="https://publications.waset.org/abstracts/94699/cracking-of-tar-analogue-in-n2-carrier-gas-using-non-thermal-plasma-dielectric-barrier-discharge-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94699.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">4046</span> Management of Nutritional Strategies in Controlling of Autism in Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Ghavam%20Sadri">Maryam Ghavam Sadri</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimia%20Moiniafshari"> Kimia Moiniafshari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objectives: The prevalence of Autism in the world has taken on a growing trend. Autism is a neuro-developmental disorder that is identified at the age of three. Studies have been shown that nutritional management can control nutritional deficiencies in Autism. This review study aimed to assess the role of nutritional management strategies for Autism in children has been made. Methods: This review study was accomplished by using the keywords related to the topic, 68 articles were found (2000-2015) and finally 15 articles with criteria such as including dietary pattern, nutritional deficiencies and Autism controlling were selected. Results: The studies showed that intake of vitamins D, E, and calcium because of restricted diet (casein and gluten free) in autistic children is less than typically developing children (TYP) (p value ≤ 0.001) and as a result of restrictions on the consumption of fresh fruits and vegetables, vitamin C and magnesium intake is less than TYP children (p value ≤ 0.001). Autistic children also get omega-3 less than TYP children. Studies have shown that food sources rich in omega-3 can improve behavioral indicators, especially in reducing hyperactivity (95% CI = -2.2 - 5.2). Zinc deficiency in these children leads to a high serum level of mercury, lead and cadmium. As a result of the repetitive dietary pattern, Sodium intake in autistic children is more than TYP children (p value < 0.001).Because of low food variety in autistic children, healthy eating index (HEI) is less than TYP children (p value = 0.008).Food selectivity in Autism due to repetitive and restricted dietary pattern and nutritional deficiencies. Conclusion: Because of restricted (casein and gluten free) and repetitive dietary pattern, the intake of some micronutrients are denied in autistic children. The nutritional strategy programs appear to help controlling of Autism. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=autism" title="autism">autism</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20selectivity" title=" food selectivity"> food selectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20intake" title=" nutrient intake"> nutrient intake</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20strategies" title=" nutritional strategies"> nutritional strategies</a> </p> <a href="https://publications.waset.org/abstracts/34249/management-of-nutritional-strategies-in-controlling-of-autism-in-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34249.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">428</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">4045</span> Effects of Residence Time on Selective Absorption of Hydrogen Suphide </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dara%20Satyadileep">Dara Satyadileep</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdallah%20S.%20Berrouk"> Abdallah S.

This paper discusses the prominence of optimum design of column internals to best achieve H2S selectivity using MDEA. To this end, a kinetics-based process simulation model has been developed for a commercial gas sweetening unit. Trends of sweet gas H2S & CO2 contents as function of fraction active area (and hence residence time) have been explained through analysis of interdependent heat and mass transfer phenomena. Guidelines for column internals design in order to achieve desired degree of H2S selectivity are provided. Also the effectiveness of various operating conditions in achieving H2S selectivity for an industrial absorber with fixed internals is investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20sweetening" title="gas sweetening">gas sweetening</a>, <a href="https://publications.waset.org/abstracts/search?q=H2S%20selectivity" title=" H2S selectivity"> H2S selectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=methyldiethanol%20amine" title=" methyldiethanol amine"> methyldiethanol amine</a>, <a href="https://publications.waset.org/abstracts/search?q=process%20simulation" title=" process simulation"> process simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=residence%20time" title=" residence time"> residence time</a> </p> <a href="https://publications.waset.org/abstracts/21361/effects-of-residence-time-on-selective-absorption-of-hydrogen-suphide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21361.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">344</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">4044</span> Enhancement of CO2 Capture by Using Cu-Nano-Zeolite Synthesized</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pham-Thi%20Huong">Pham-Thi Huong</a>, <a href="https://publications.waset.org/abstracts/search?q=Byeong-Kyu%20Lee"> Byeong-Kyu Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi-Hyeon%20Lee"> Chi-Hyeon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jitae%20Kim"> Jitae Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study synthesized Cu-nano-zeolite was evaluated for its potential use in CO2 capture.

The experiments were conducted at various gas hourly space velocity (GHSV), reaction temperature, and feed concentration. No catalyst deactivation was observed over the reaction time of 16 hours. Two major reaction products were trans-2-butene and cis-2-butene. The reaction temperature played an important role on the reaction selectivity. At high operating temperatures, the selectivity of trans-2-butene was higher than the selectivity of cis-2-butene while it was opposite at a lower reaction temperature. In the range of operating conditions, the maximum conversion of 1-butene was found at 74% when T = 673 K and GHSV = 4 m3/h/kg-cat with trans- and cis-2-butene selectivities of 54% and 46% respectively.

Argon was used as balance gas when the feed-gas ratio was changed, which can keep the partial pressure of the other two kinds of gas constant while the ratio of one component in feed-gas was changed. First, the effect of single-component gas ratio on the performance of ethene hydroformylation was studied one by one (H₂, C₂H₄ and CO). Then an optimized ratio was found to obtain a high selectivity to C₃ oxygenates. The results showed that: (1) 0.5%Rh-20%Co/RGO is a promising heterogeneous catalyst for ethene hydroformylation. (2) H₂ and CO have a more significant influence than C₂H₄ on selectivity to oxygenates. (3) A lower H₂ ratio and a higher CO ratio in feed-gas can lead to a higher selectivity to oxygenates. (4) The highest selectivity to oxygenates, 61.70%, was obtained at the feed-gas ratio CO: C₂H₄: H₂ = 4: 2: 1. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ethene%20hydroformylation" title="ethene hydroformylation">ethene hydroformylation</a>, <a href="https://publications.waset.org/abstracts/search?q=reduced%20graphene%20oxide" title=" reduced graphene oxide"> reduced graphene oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=rhodium%20cobalt%20bimetallic%20catalyst" title=" rhodium cobalt bimetallic catalyst"> rhodium cobalt bimetallic catalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20effect%20of%20feed-gas%20ratio" title=" the effect of feed-gas ratio"> the effect of feed-gas ratio</a> </p> <a href="https://publications.waset.org/abstracts/146368/the-influence-of-feedgas-ratio-on-the-ethene-hydroformylation-using-rh-co-bimetallic-catalyst-supported-by-reduced-graphene-oxide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146368.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">163</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">4040</span> The Effect of Arabic Gum on Polyethersulfone Membranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yehia%20Manawi">Yehia Manawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Viktor%20Kochkodan"> Viktor Kochkodan</a>, <a href="https://publications.waset.org/abstracts/search?q=Muataz%20Hussien"> Muataz Hussien</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the effect of adding Arabic Gum (AG) to the dope solutions of polyethersulfone (PES) was studied.

In a context of high volumes of water and low concentration of contaminants, adsorption/interchange processes are appealing since they meet the required features. Iron oxides such as siderite and molysite, which are respectively based on FeCO<sub>3</sub> and FeCl<sub>3</sub>, can be found in nature. In this work, their observed performance, raw or roasted at different temperatures, as adsorbents of some inorganic anions is discussed.

This is both perplexing and daunting given that not all that is wasted is accounted for when measuring food waste. It is recognised that the present food waste definitions are ambiguous and do not really take into account all food waste generated. The contention is that food waste in the food service sector can be prevented or reduced if we have an explicit food waste definition in the context of food service. This study, therefore, explores the definition of the concept of food waste in the food service sector and its implications on sustainable food waste management strategies. An ethnographic research approach was adopted. A university food service unit was selected as a research site. Data collection techniques employed included document analyses, participant observations, focus group discussions with front-of-house and back-of-house staff, and one-on-one interviews with staff on managerial positions. A grounded theory approach was applied to analyse data. The concept of food waste was constructed differently by different levels of staff. Whereas managers raised discussion from a financial perspective, BOH and FOH staff drew upon socio-cultural implications. This study lays the foundation for a harmonised definition of the concept of food waste in food service. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20service" title="food service">food service</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste" title=" food waste"> food waste</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste%20management" title=" food waste management"> food waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/85967/re-defining-food-waste-and-food-waste-management-in-the-food-service-sector-a-case-study-in-a-university-food-service-unit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85967.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">274</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">4031</span> Mapping Protein Selectivity Landscapes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Niv%20Papo">Niv Papo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Characterizing the binding selectivity landscape of interacting proteins is crucial both for elucidating the underlying mechanisms of their interaction and for developing selective inhibitors. However, current mapping methods are laborious and cannot provide a sufficiently comprehensive description of the landscape. Here, we introduce a distinct and efficient strategy for comprehensively mapping the binding landscape of proteins using a combination of experimental multi-target selective library screening and in silico next-generation sequencing analysis. We map the binding landscape of a non-selective trypsin inhibitor, the amyloid protein precursor inhibitor (APPI), to each of four human serine proteases (kallikrein-6, mesotrypsin, and anionic and cationic trypsins). We then use this map to dissect and improve the affinity and selectivity of APPI variants toward each of the four proteases. Our strategy can be used as a platform for the development of a new generation of target-selective probes and therapeutic agents based on selective protein–protein interactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drug%20design" title="drug design">drug design</a>, <a href="https://publications.waset.org/abstracts/search?q=directed%20evolution" title=" directed evolution"> directed evolution</a>, <a href="https://publications.waset.org/abstracts/search?q=protein%20engineering" title=" protein engineering"> protein engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=protease%20inhibition." title=" protease inhibition."> protease inhibition.</a> </p> <a href="https://publications.waset.org/abstracts/191315/mapping-protein-selectivity-landscapes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191315.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">24</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">4030</span> Legal Issues of Food Security in Republic of Kazakhstan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20T.%20Aigarinova">G.

In Saudi Arabia matters related to food safety and hygiene have been the heart of the Ministry of Health (MOH) and Saudi Food and Drugs Authority (SFDA). The aim of this study is to examine the causes of inadequate implementation of food safety management systems such as HACCP in Riyadh’s MOH hospitals. By the law, food safety must be managed using a documented, HACCP based approach, and food handlers must be appropriately trained in food safety. Food handlers in Saudi Arabia are not required to provide a certificate or attend a food handling training course even in healthcare sectors. Since food safety and hygiene issues are of increasing importance for Saudi Arabian health decision makers, the SFDA has been established to apply food hygiene requirements in all food operations. It should be pointed out that the implications of food outbreaks on the whole society may potentially go beyond individual health impacts but also impact on the Nation’s health and bring about economic repercussions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20safety" title="food safety">food safety</a>, <a href="https://publications.waset.org/abstracts/search?q=patient" title=" patient"> patient</a>, <a href="https://publications.waset.org/abstracts/search?q=hospital" title=" hospital"> hospital</a>, <a href="https://publications.waset.org/abstracts/search?q=HACCP" title=" HACCP"> HACCP</a> </p> <a href="https://publications.waset.org/abstracts/68800/food-safety-management-in-riyadhs-ministry-of-health-hospitals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68800.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">872</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">4026</span> Primal Instinct: Formation of Food Aversion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zihuan%20%28Dylan%29%20Wang">Zihuan (Dylan) Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyzes the formation of human food aversion from a biological perspective.

To reduce food waste in a sustainable manner, it requires an understanding of the generation of food waste. This paper assesses household food wastage in the City of Tshwane Metropolitan Municipality (CTMM). A total of 210 interviewed participants using face-to-face interviews based on a structured questionnaire and the actual weighing of households’ food wasted was quantified using a weighing kitchen scale. Fifty-nine percent of respondents agreed that they wasted food, while 41% thought they did not waste food at all. Households wasted an average total of 6 kg of food waste per week per household. The study concluded that households buy and prepare more food that ends up wasted. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=developing%20country" title=" developing country"> developing country</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste" title=" food waste"> food waste</a>, <a href="https://publications.waset.org/abstracts/search?q=household" title=" household"> household</a> </p> <a href="https://publications.waset.org/abstracts/59145/household-food-wastage-assessment-a-case-study-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59145.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">320</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">4024</span> Unsaturated Sites Constructed Grafted Polymer Nanoparticles to Promote CO₂ Separation in Mixed-Matrix Membranes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Boyu%20Li">Boyu Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mixed matrix membranes (MMMs), as a separation technology, can improve CO₂ recycling efficiency and reduce the environmental impacts associated with huge emissions. Nevertheless, many challenges must be overcome to design excellent selectivity and permeability performance MMMs. Herein, this work demonstrates the design of nano-scale GNPs (Cu-BDC@PEG) with strong compatibility and high free friction volume (FFV) is an effective way to construct non-interfacial voids MMMs with a desirable combination of selectivity and permeability. Notably, the FFV boosted thanks to the chain length and shape of the GNPs. With this, the permeability and selectivity of Cu-BDC@PEG/PVDF MMMs had also been significantly improved. As such, compatible Cu-BDC@PEG proves very efﬁcient for resolving challenges of MMMs with poor compatibility on the basis of the interfacial defect. Poly (Ethylene Glycol) (PEG) with oxygen groups can be ﬁnely coordinated with Cu-MOFs to disperse Cu-BDC@PEG homogenously and form hydrogen bonds with matrix to achieve continuous phase. The resultant MMMs exhibited a simultaneous enhancement of gas permeability (853.1 Barrer) and ideal CO₂/N selectivity (41.7), which has surpassed Robenson's upper bound. Moreover, Cu-BDC@PEG/PVDF has a high-temperature resistance and a long time sustainably. This attractive separation performance of Cu-BDC@PEG/PVDF oﬀered an exciting platform for the development of composite membranes for sustainable CO₂ separations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal%20organic%20framework" title="metal organic framework">metal organic framework</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20separation" title=" CO₂ separation"> CO₂ separation</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20matrix%20membrane" title=" mixed matrix membrane"> mixed matrix membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer" title=" polymer"> polymer</a> </p> <a href="https://publications.waset.org/abstracts/165561/unsaturated-sites-constructed-grafted-polymer-nanoparticles-to-promote-co2-separation-in-mixed-matrix-membranes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165561.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">117</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">4023</span> Selective Electrooxidation of Ammonia to Nitrogen Gas on the Crystalline Cu₂O/Ni Foam Electrode</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ming-Han%20Tsai">Ming-Han Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Chihpin%20Huang"> Chihpin Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrochemical oxidation of ammonia (AEO) is one of the highly efficient and environmentally friendly methods for NH₃ removal from wastewater. Recently, researchers have focused on non-Pt-based electrodes (n-PtE) for AEO, aiming to evaluate the feasibility of these low-cost electrodes for future practical applications. However, for most n-PtE, NH₃ is oxidized mainly to nitrate ion NO₃⁻ instead of the desired nitrogen gas N₂, which requires further treatment to remove excess NO₃⁻. Therefore, developing a high N₂ conversion electrode for AEO is highly urgent. In this study, we fabricated various Cu₂O/Ni foam (NF) electrodes by electrodeposition of Cu on NF. The Cu plating bath contained different additives, including cetyltrimethylammonium chloride (CTAC), sodium dodecyl sulfate (SDS), polyamide acid (PAA), and sodium alginate (SA). All the prepared electrodes were physically and electrochemically investigated. Batch AEO experiments were conducted for 3 h to clarify the relation between electrode structures and N₂ selectivity. The SEM and XRD results showed that crystalline platelets-like Cu₂O, particles-like Cu₂O, cracks-like Cu₂O, and sheets-like Cu₂O were formed in the Cu plating bath by adding CTAC, SDS, PAA, and SA, respectively. For electrochemical analysis, all Cu₂O/NF electrodes revealed a higher current density (2.5-3.2 mA/cm²) compared to that without additives modification (1.6 mA/cm²). At a constant applied potential of 0.95 V (vs Hg/HgO), the Cu₂O sheet (51%) showed the highest N₂ selectivity, followed by Cu₂O cracks (38%), Cu₂O particles (30%), and Cu₂O platelet (18%) after 3 h reaction. Our result demonstrated that the selectivity of N₂ during AEO was surface structural dependent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ammonia" title="ammonia">ammonia</a>, <a href="https://publications.waset.org/abstracts/search?q=electrooxidation" title=" electrooxidation"> electrooxidation</a>, <a href="https://publications.waset.org/abstracts/search?q=selectivity" title=" selectivity"> selectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=cuprous%20oxide" title=" cuprous oxide"> cuprous oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=Ni%20foam" title=" Ni foam"> Ni foam</a> </p> <a href="https://publications.waset.org/abstracts/155711/selective-electrooxidation-of-ammonia-to-nitrogen-gas-on-the-crystalline-cu2oni-foam-electrode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155711.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">86</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">4022</span> The Effect of Fast Food Globalisation on Students’ Food Choice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ijeoma%20Chinyere%20Ukonu">Ijeoma Chinyere Ukonu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research seeks to investigate how the globalisation of fast food has affected students’ food choice. A mixed method approach was used in this research; basically involving quantitative and qualitative methods. The quantitative method uses a self-completion questionnaire to randomly sample one hundred and four students; while the qualitative method uses a semi structured interview technique to survey four students on their knowledge and choice to consume fast food. A cross tabulation of variables and the Kruskal Wallis nonparametric test were used to analyse the quantitative data; while the qualitative data was analysed through deduction of themes, and trends from the interview transcribe. The findings revealed that globalisation has amplified the evolution of fast food, popularising it among students. Its global presence has affected students’ food choice and preference. Price, convenience, taste, and peer influence are some of the major factors affecting students’ choice of fast food. Though, students are familiar with the health effect of fast food and the significance of using food information labels for healthy choice making, their preference of fast food is more than homemade food. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fast%20food" title="fast food">fast food</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20choice" title=" food choice"> food choice</a>, <a href="https://publications.waset.org/abstracts/search?q=globalisation" title=" globalisation"> globalisation</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a> </p> <a href="https://publications.waset.org/abstracts/47399/the-effect-of-fast-food-globalisation-on-students-food-choice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47399.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">291</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">4021</span> Reactive Learning about Food Waste Reduction in a Food Processing Plant in Gauteng Province, South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nesengani%20Elelwani%20Clinton">Nesengani Elelwani Clinton</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents reflective learning as an opportunity commonly available and used for food waste learning in a food processing company in the transition to sustainable and just food systems. In addressing how employees learn about food waste during food processing, the opportunities available for food waste learning were investigated. Reflective learning appeared to be the most used approach to learning about food waste. In the case of food waste learning, reflective learning was a response after employees wasted a substantial amount of food, where process controllers and team leaders would highlight the issue to employees who wasted food and explain how food waste could be reduced. This showed that learning about food waste is not proactive, and there continues to be a lack of structured learning around food waste. Several challenges were highlighted around reflective learning about food waste. Some of the challenges included understanding the language, lack of interest from employees, set times to reach production targets, and working pressures. These challenges were reported to be hindering factors in understanding food waste learning, which is not structured. A need was identified for proactive learning through structured methods. This is because it was discovered that in the plant, where food processing activities happen, the signage and posters that are there are directly related to other sustainability issues such as food safety and health. This indicated that there are low levels of awareness about food waste. Therefore, this paper argues that food waste learning should be proactive. The proactive learning approach should include structured learning materials around food waste during food processing. In the structuring of the learning materials, individual trainers should be multilingual. This will make it possible for those who do not understand English to understand in their own language. And lastly, there should be signage and posters in the food processing plant around food waste. This will bring more awareness around food waste, and employees' behaviour can be influenced by the posters and signage in the food processing plant. Thus, will enable a transition to a just and sustainable food system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20and%20just%20food%20systems" title="sustainable and just food systems">sustainable and just food systems</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste" title=" food waste"> food waste</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste%20learning" title=" food waste learning"> food waste learning</a>, <a href="https://publications.waset.org/abstracts/search?q=reflective%20learning%20approach" title=" reflective learning approach"> reflective learning approach</a> </p> <a href="https://publications.waset.org/abstracts/163668/reactive-learning-about-food-waste-reduction-in-a-food-processing-plant-in-gauteng-province-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163668.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">130</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">4020</span> Sustainable Food Systems in Community Development: Integrating Urban Food Security into a Growing Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Opal%20Giulianelli">Opal Giulianelli</a>, <a href="https://publications.waset.org/abstracts/search?q=Pegah%20Zamani"> Pegah Zamani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sustainable food has become a frequently debated topic in recent years due to a consumer push for environmentally sustainable food. While some research works on improving the monoculture farm systems that are currently in use, others focus on expanding the definition of sustainable food systems. This research looks at those concepts of alternative food systems applied to a more extensive city system. The goal is to create a theoretical site plan that could be implemented in emerging cities and other urban environments. This site plan combines the ideas of environmentally sustainable food development, such as food forests, urban farming, and community gardens. This would represent one part of a larger sustainable food system that can be altered depending on the environment or the people it is serving. However, this research is being carried out with the southeast United States in mind and, therefore, may prove difficult to apply to other regions, especially those of radically different climates. <p
