Commonly referred to as produced water, most industrial water-based produced water methods use the method of pumping water back into wells or catchment areas. because it cannot be utilized further, but in the compression of water each time, the cost is quite high. And the survey found that the amount of water from the petroleum production process has increased every year. In this research, we would like to study the removal of oil in produced water by the Coalescer device using fibers from agricultural waste as an intermediary. As an alternative to reduce the cost of water management in the petroleum drilling industry. The objectives of this research are 1. To study the fiber pretreatment by chemical process for the efficiency of oil-water separation 2. To study and design the fiber-packed coalescer device to destroy the emulsion of crude oil in water. 3. To study the working conditions of coalescer devices in emulsion destruction. using a fiber medium. In this research, the experiment was divided into two parts. The first part will study the absorbency of fibers. It compares untreated fibers with chemically treated alkaline fibers that change over time as well as adjusting the amount of fiber on the absorbency of the fiber and the second part will study the separation of oil from produced water by Coalescer equipment using fiber as medium to study the optimum condition of coalescer equipment for further development and industrial application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=produced%20water" title="produced water">produced water</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber" title=" fiber"> fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20modification" title=" surface modification"> surface modification</a>, <a href="https://publications.waset.org/abstracts/search?q=coalescer" title=" coalescer"> coalescer</a> </p> <a href="https://publications.waset.org/abstracts/144197/demulsification-of-oil-from-produced-water-using-fibrous-coalescer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144197.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">166</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">11</span> Evaluation Criteria for Performance of Knitted Terry Fabrics and Building Elements of Fashion: A Critical Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harpinder%20Kaur">Harpinder Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Amit%20Madahar"> Amit Madahar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The terry fabric is one of the fastest growing and challenging sub-sectors of the textile industry. Terry fabrics are produced using ground weft, ground warp, and pile yarns. The terry fabrics not only finds applications in towels but also in home textile products, sauna dressing- gowns, slippers, jackets, garments, apparels, outerwears, overcoats, sweatshirts, children’s clothes, and hygiene products for babies, beachwear, sleepwear, gloves, scarfs, shawls, etc. In some cases, these wide ranges of applications not only demand a high degree of absorption but also necessitate the due consideration for the handle properties of the fabrics. These fabrics are required to be accessed for their performance in terms of absorbency and comfort characteristics. Since material (yarns, colors, fabrics, fashion, patrons, accessories and fittings) are the core elements of structure of fashion, hence textile and fashion go hand in hand. This paper throws some light on the performance evaluation of terry fabrics. Here, characteristics/features that are required to be achieved for satisfactory performance of the terry fabrics with reference to fashion are discussed. The terry fabrics are being modified over the years in terms of the raw material requirements such as 100% cotton or blends or cotton with other fibers in order to obtain better performance as well as their structural parameters including stitch length and stitch density etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorbency" title="absorbency">absorbency</a>, <a href="https://publications.waset.org/abstracts/search?q=comfort" title=" comfort"> comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=cotton" title=" cotton"> cotton</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=terry%20fabrics" title=" terry fabrics"> terry fabrics</a>, <a href="https://publications.waset.org/abstracts/search?q=fashion" title=" fashion"> fashion</a> </p> <a href="https://publications.waset.org/abstracts/104752/evaluation-criteria-for-performance-of-knitted-terry-fabrics-and-building-elements-of-fashion-a-critical-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104752.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">146</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">10</span> Synthesis and Characterization of Carboxymethyl Cellulose-Chitosan Based Composite Hydrogels for Biomedical and Non-Biomedical Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Uyanga">K.

Limitations on extending their applications have resulted from the synthesis of hydrogels using toxic materials and complex irreproducible processing techniques. In order to promote environmental sustainability, hydrogel efficiency, and wider application, this study focused on the synthesis of composite hydrogels matrices from an edible non-toxic crosslinker-citric acid (CA) using a simple low energy processing method based on carboxymethyl cellulose (CMC) and chitosan (CSN) natural polymers. Composite hydrogels were developed by chemical crosslinking. The results demonstrated that CMC:2CSN:CA exhibited good performance properties and super-absorbency 21× its original weight. This makes it promising for biomedical applications such as chronic wound healing and regeneration, next generation skin substitute, in situ bone regeneration and cell delivery. On the other hand, CMC:CSN:CA exhibited durable well-structured internal network with minimum swelling degrees, water absorbency, excellent gel fraction, and infra-red reflectance. These properties make it a suitable composite hydrogel matrix for warming effect and controlled and efficient release of loaded materials. CMC:2CSN:CA and CMC:CSN:CA composite hydrogels developed also exhibited excellent chemical, morphological, and thermal properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=citric%20acid" title="citric acid">citric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=fumaric%20acid" title=" fumaric acid"> fumaric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=tartaric%20acid" title=" tartaric acid"> tartaric acid</a>, <a href="https://publications.waset.org/abstracts/search?q=zinc%20nitrate%20hexahydrate" title=" zinc nitrate hexahydrate"> zinc nitrate hexahydrate</a> </p> <a href="https://publications.waset.org/abstracts/110048/synthesis-and-characterization-of-carboxymethyl-cellulose-chitosan-based-composite-hydrogels-for-biomedical-and-non-biomedical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110048.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">151</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">9</span> Synthesis and Properties of Chitosan-Graft-Polyacrylamide/Gelatin Superabsorbent Composites for Wastewater Purification</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hafida%20Ferfera-Harrar">Hafida Ferfera-Harrar</a>, <a href="https://publications.waset.org/abstracts/search?q=Nacera%20Aiouaz"> Nacera Aiouaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Nassima%20Dairi"> Nassima Dairi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Super absorbents polymers received much attention and are used in many ﬁelds because of their superior characters to traditional absorbents, e.g., sponge and cotton. So, it is very important but challenging to prepare highly and fast-swelling super absorbents. A reliable, efficient and low-cost technique for removing heavy metal ions from waste water is the adsorption using bio-adsorbents obtained from biological materials, such as polysaccharides-based hydrogels super absorbents. In this study, novel multi-functional super absorbent composites type semi-interpenetrating polymer networks (Semi-IPNs) were prepared via graft polymerization of acrylamide onto chitosan backbone in presence of gelatin, CTS-g-PAAm/Ge, using potassium persulfate and N,N’ -methylenebisacrylamide as initiator and cross linker, respectively. These hydrogels were also partially hydrolyzed to achieve superabsorbents with ampholytic properties and uppermost swelling capacity. The formation of the grafted network was evidenced by Fourier Transform Infrared Spectroscopy (ATR-FTIR) and thermo gravimetric Analysis (TGA). The porous structures were observed by Scanning Electron Microscope (SEM). From TGA analysis, it was concluded that the incorporation of the Ge in the CTS-g-PAAm network has marginally affected its thermal stability. The effect of gelatin content on the swelling capacities of these super absorbent composites was examined in various media (distilled water, saline and pH-solutions).The water absorbency was enhanced by adding Ge in the network, where the optimum value was reached at 2 wt. % of Ge. Their hydrolysis has not only greatly optimized their absorption capacity but also improved the swelling kinetic. These materials have also showed reswelling ability. We believe that these super-absorbing materials would be very effective for the adsorption of harmful metal ions from waste water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chitosan" title="chitosan">chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=gelatin" title=" gelatin"> gelatin</a>, <a href="https://publications.waset.org/abstracts/search?q=superabsorbent" title=" superabsorbent"> superabsorbent</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20absorbency" title=" water absorbency"> water absorbency</a> </p> <a href="https://publications.waset.org/abstracts/25966/synthesis-and-properties-of-chitosan-graft-polyacrylamidegelatin-superabsorbent-composites-for-wastewater-purification" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25966.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">463</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">8</span> Production of a Sustainable Slow-Release Urea Fertilizer Using Starch and Poly-Vinyl Alcohol</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20M.%20H.%20Shokry">A.

One particular technique has been to coat urea fertilizer granules with less-soluble chemicals that permit the gradual release of nutrients in a slow and controlled manner. The aim of this research is to develop a biodegradable slow-release fertilizer (SRF) with materials that come from sustainable sources; starch and polyvinyl alcohol (PVA). The slow-release behavior and water retention capacity of the coated granules were determined. In addition, the aqueous release and absorbency rates were also tested. Results confirmed that the release rate from coated granules was slower than through plain membranes; and that the water absorption capacity of the coated urea decreased as PVA content increased. The SRF was also tested and gave positive results that confirmed the integrity of the product. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradability" title="biodegradability">biodegradability</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen-use%20efficiency" title=" nitrogen-use efficiency"> nitrogen-use efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=poly-vinyl%20alcohol" title=" poly-vinyl alcohol"> poly-vinyl alcohol</a>, <a href="https://publications.waset.org/abstracts/search?q=slow-release%20fertilizer" title=" slow-release fertilizer"> slow-release fertilizer</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/139377/production-of-a-sustainable-slow-release-urea-fertilizer-using-starch-and-poly-vinyl-alcohol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139377.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">214</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">7</span> Synthesis, Characterization, and Evaluation of New Series of Oil Sorbers Based on Maleate Esters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nora%20A.%20Hamad">Nora A.

As a result, the expectations of people regarding textile, comfort, pattern (texture) and color properties are increasing. One of the places where comfort is most sought after is bath, pool, sea and baths. In addition to the material and technique that make up the physical structure in woven fabrics, color has an impressive importance with its strong effects. Color is the most prominent element in the fabric, and the color and texture are visually reinforcing. Evaluation of color in fabric is a personal phenomenon. Factors that determine color determination in fabric are the amount of color used, color ratio and its relationship with other colors. In this project; Considering the effect of color dimensions on human, we are talking about the crystallized colored towel that we developed in terms of comfort and texture properties. The basis of the effect created in the towel; It is formed by bending the yarn from its own special blend and the harmonious appearance of the natural crystallized rainbow colors with the pattern effect it determines on the warp yarns by using the weft yarns in the weaving. In addition, by using different weaving techniques and colors, alternatives can be created and personalized patterns can be created. One side of the towel determines the properties related to color, while the pile part determines the comfort characteristics with its soft touch and water absorbency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=color%20effect" title="color effect">color effect</a>, <a href="https://publications.waset.org/abstracts/search?q=comfort" title=" comfort"> comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=towel" title=" towel"> towel</a>, <a href="https://publications.waset.org/abstracts/search?q=weaving%20technique" title=" weaving technique"> weaving technique</a> </p> <a href="https://publications.waset.org/abstracts/109054/crystallized-colored-towels-obtained-by-special-coloration-of-yarns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109054.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">162</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">5</span> Preparation and Modeling Carbon Nanofibers as an Adsorbent to Protect the Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Ziaei">Maryam Ziaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeedeh%20Rafiei"> Saeedeh Rafiei</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Mivehi"> Leila Mivehi</a>, <a href="https://publications.waset.org/abstracts/search?q=Akbar%20Khodaparast%20Haghi"> Akbar Khodaparast Haghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon nanofibers possess properties that are rarely present in any other types of carbon adsorbents, including a small cross-sectional area, combined with a multitude of slit shaped nanopores that are suitable for adsorption of certain types of molecules. Because of their unique properties these materials can be used for the selective adsorption of organic molecules. On the other hand, activated carbon fiber (ACF) has been widely applied as an effective adsorbent for micro-pollutants in recent years. ACF effectively adsorbs and removes a full spectrum of harmful substances. Although there are various methods of fabricating carbon nanofibres, electrospinning is perhaps the most versatile procedure. This technique has been given great attention in current decades because of the nearly simple, comfortable and low cost. Spinning process control and achieve optimal conditions is important in order to effect on its physical properties, absorbency and versatility with different industrial purposes. Modeling and simulation are suitable methods to obtain this approach. In this paper, activated carbon nanofibers were produced during electrospinning of polyacrylonitrile solution.

Despite their exceptional nutritional profile and resilience to harsh environmental conditions, their potential remains largely untapped. This study aims to contribute to the valorization of seven Algerian pearl millet landraces (Pennisetum glaucum (L.) R. Br) from the southern region by focusing on the characterization of their starches. Utilizing both conventional wet milling, incorporating sodium azide as a microbial growth inhibitor, and a novel green technology—Ultrasound-assisted isolation, we explore avenues for enhancing the functional properties of these starches. Analysis of key functional properties such as swelling power and water solubility index reveals significant enhancements, particularly during heat treatment near the gelatinization temperature [70 - 80 °C]. Furthermore, our investigation into the influence of pre-treatment methods on isolated starches highlights the potential of Ultrasound-assisted isolation in reducing absorbency and water solubility compared to conventional methods. Through rigorous data analysis using SPSS software (Version 23), we ascertain the efficiency of Ultrasound-assisted isolation, underscoring its promising role in the valorization of pearl millet waste. This research not only sheds light on the functional properties of pearl millet starch but also underscores the imperative of sustainable waste management in harnessing the full potential of underutilized cereal resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=isolation" title="isolation">isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=solubility" title=" solubility"> solubility</a>, <a href="https://publications.waset.org/abstracts/search?q=starch" title=" starch"> starch</a>, <a href="https://publications.waset.org/abstracts/search?q=swelling" title=" swelling"> swelling</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasound" title=" ultrasound"> ultrasound</a> </p> <a href="https://publications.waset.org/abstracts/185147/unlocking-the-potential-of-neglected-cereal-resources-waste-exploring-functional-properties-of-algerian-pearl-millet-starch-via-wet-milling-and-ultrasound-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185147.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">65</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">3</span> Cupric Oxide Thin Films for Optoelectronic Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sanjay%20Kumar">Sanjay Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Dinesh%20Pathak"> Dinesh Pathak</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudhir%20Saralch"> Sudhir Saralch</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Copper oxide is a semiconductor that has been studied for several reasons such as the natural abundance of starting material copper (Cu); the easiness of production by Cu oxidation; their non-toxic nature and the reasonably good electrical and optical properties. Copper oxide is well-known as cuprite oxide. The cuprite is p-type semiconductors having band gap energy of 1.21 to 1.51 eV. As a p-type semiconductor, conduction arises from the presence of holes in the valence band (VB) due to doping/annealing. CuO is attractive as a selective solar absorber since it has high solar absorbency and a low thermal emittance. CuO is very promising candidate for solar cell applications as it is a suitable material for photovoltaic energy conversion. It has been demonstrated that the dip technique can be used to deposit CuO films in a simple manner using metallic chlorides (CuCl₂.2H₂O) as a starting material. Copper oxide films are prepared using a methanolic solution of cupric chloride (CuCl₂.2H₂O) at three baking temperatures. We made three samples, after heating which converts to black colour. XRD data confirm that the films are of CuO phases at a particular temperature. The optical band gap of the CuO films calculated from optical absorption measurements is 1.90 eV which is quite comparable to the reported value. Dip technique is a very simple and low-cost method, which requires no sophisticated specialized setup. Coating of the substrate with a large surface area can be easily obtained by this technique compared to that in physical evaporation techniques and spray pyrolysis. Another advantage of the dip technique is that it is very easy to coat both sides of the substrate instead of only one and to deposit otherwise inaccessible surfaces. This method is well suited for applying coating on the inner and outer surfaces of tubes of various diameters and shapes. The main advantage of the dip coating method lies in the fact that it is possible to deposit a variety of layers having good homogeneity and mechanical and chemical stability with a very simple setup. In this paper, the CuO thin films preparation by dip coating method and their characterization will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorber%20material" title="absorber material">absorber material</a>, <a href="https://publications.waset.org/abstracts/search?q=cupric%20oxide" title=" cupric oxide"> cupric oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=dip%20coating" title=" dip coating"> dip coating</a>, <a href="https://publications.waset.org/abstracts/search?q=thin%20film" title=" thin film"> thin film</a> </p> <a href="https://publications.waset.org/abstracts/82434/cupric-oxide-thin-films-for-optoelectronic-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82434.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">309</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">2</span> Sequential Padding: A Method to Improve the Impact Resistance in Body Armor Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankita%20Srivastava">Ankita Srivastava</a>, <a href="https://publications.waset.org/abstracts/search?q=Bhupendra%20S.%20Butola"> Bhupendra S. Butola</a>, <a href="https://publications.waset.org/abstracts/search?q=Abhijit%20Majumdar"> Abhijit Majumdar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Application of shear thickening fluid (STF) has been proved to increase the impact resistance performance of the textile structures to further use it as a body armor material. In the present research, STF was applied on Kevlar woven fabric to make the structure lightweight and flexible while improving its impact resistance performance. It was observed that getting a fair amount of add-on of STF on Kevlar fabric is difficult as Kevlar fabric comes with a pre-coating of PTFE which hinders its absorbency. Hence, a method termed as sequential padding is developed in the present study to improve the add-on of STF on Kevlar fabric. Contrary to the conventional process, where Kevlar fabric is treated with STF once using any one pressure, in sequential padding method, the Kevlar fabrics were treated twice in a sequential manner using combination of two pressures together in a sample. 200 GSM Kevlar fabrics were used in the present study. STF was prepared by adding PEG with 70% (w/w) nano-silica concentration. Ethanol was added with the STF at a fixed ratio to reduce viscosity. A high-speed homogenizer was used to make the dispersion. Total nine STF treated Kevlar fabric samples were prepared by using varying combinations and sequences of three levels of padding pressure {0.5, 1.0 and 2.0 bar). The fabrics were dried at 80°C for 40 minutes in a hot air oven to evaporate ethanol. Untreated and STF treated fabrics were tested for add-on%. Impact resistance performance of samples was also tested on dynamic impact tester at a fixed velocity of 6 m/s. Further, to observe the impact resistance performance in actual condition, low velocity ballistic test with 165 m/s velocity was also performed to confirm the results of impact resistance test. It was observed that both add-on% and impact energy absorption of Kevlar fabrics increases significantly with sequential padding process as compared to untreated as well as single stage padding process. It was also determined that impact energy absorption is significantly better in STF treated Kevlar fabrics when 1st padding pressure is higher, and 2nd padding pressure is lower. It is also observed that impact energy absorption of sequentially padded Kevlar fabric shows almost 125% increase in ballistic impact energy absorption (40.62 J) as compared to untreated fabric (18.07 J).The results are owing to the fact that the treatment of fabrics at high pressure during the first padding is responsible for uniform distribution of STF within the fabric structures. While padding with second lower pressure ensures the high add-on of STF for over-all improvement in the impact resistance performance of the fabric. Therefore, it is concluded that sequential padding process may help to improve the impact performance of body armor materials based on STF treated Kevlar fabrics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=body%20armor" title="body armor">body armor</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20resistance" title=" impact resistance"> impact resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevlar" title=" Kevlar"> Kevlar</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20thickening%20fluid" title=" shear thickening fluid"> shear thickening fluid</a> </p> <a href="https://publications.waset.org/abstracts/92928/sequential-padding-a-method-to-improve-the-impact-resistance-in-body-armor-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/92928.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">240</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">1</span> The Production of Reinforced Insulation Bricks out of the Concentration of Ganoderma lucidum Fungal Inoculums and Cement Paste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jovie%20Esquivias%20Nicolas">Jovie Esquivias Nicolas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ron%20Aldrin%20Lontoc%20Austria"> Ron Aldrin Lontoc Austria</a>, <a href="https://publications.waset.org/abstracts/search?q=Crisabelle%20Belleza%20Bautista"> Crisabelle Belleza Bautista</a>, <a href="https://publications.waset.org/abstracts/search?q=Mariane%20Chiho%20Espinosa%20Bundalian"> Mariane Chiho Espinosa Bundalian</a>, <a href="https://publications.waset.org/abstracts/search?q=Owwen%20Kervy%20Del%20Rosario%20Castillo"> Owwen Kervy Del Rosario Castillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mary%20Angelyn%20Mercado%20Dela%20Cruz"> Mary Angelyn Mercado Dela Cruz</a>, <a href="https://publications.waset.org/abstracts/search?q=Heinrich%20Theraja%20Recana%20De%20Luna"> Heinrich Theraja Recana De Luna</a>, <a href="https://publications.waset.org/abstracts/search?q=Chriscell%20Gipanao%20Eustaquio"> Chriscell Gipanao Eustaquio</a>, <a href="https://publications.waset.org/abstracts/search?q=Desiree%20Laine%20Lauz%20Gilbas"> Desiree Laine Lauz Gilbas</a>, <a href="https://publications.waset.org/abstracts/search?q=Jordan%20Ignacio%20Legaspi"> Jordan Ignacio Legaspi</a>, <a href="https://publications.waset.org/abstracts/search?q=Larah%20Denise%20David%20Madrid"> Larah Denise David Madrid</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Linelle%20Malapote%20Mendoza"> Charles Linelle Malapote Mendoza</a>, <a href="https://publications.waset.org/abstracts/search?q=Hazel%20Maxine%20Manalad%20Reyes"> Hazel Maxine Manalad Reyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Carl%20Justine%20Nabora%20Saberdo"> Carl Justine Nabora Saberdo</a>, <a href="https://publications.waset.org/abstracts/search?q=Claire%20Mae%20Rendon%20Santos"> Claire Mae Rendon Santos</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In response to the global race in discovering the next advanced sustainable material that will reduce our ecological footprint, the researchers aimed to create a masonry unit which is competent in physical edifices and other constructional facets. From different proven researches, mycelium has been concluded that when dried can be used as a robust and waterproof building material that can be grown into explicit forms, thus reducing the processing requirements. Hypothesizing inclusive measures to attest fungi’s impressive structural qualities and absorbency, the researchers projected to perform comparative analyses in creating mycelium bricks from mushroom spores of G. lucidum. Three treatments were intended to classify the most ideal concentration of clay and substrate fixings. The substrate bags fixed with 30% clay and 70% mixings indicated highest numerical frequencies in terms of full occupation of fungal mycelia. Subsequently, sorted parts of white portions from the treatment were settled in a thermoplastic mold and burnt. Three proportional concentrations of cultivated substrate and cement were also prioritized to gather results of variation focused on the weights of the bricks in the Water Absorption Test and Durability Test. Fungal inoculums with solutions of cement showed small to moderate amounts of decrease and increase in load. This proves that the treatments did not show any significant difference when it comes to strength, efficiency and absorption capacity. Each of the concentration is equally valid and could be used in supporting the worldwide demands of creating numerous bricks while also taking into consideration the recovery of our nature. <p
