However, the most popular water filtration method available is the reverse osmosis (RO) technique, still suffers from important drawbacks, such as a large energy demands and high process costs. In addition some serious limitations have been recently discovered, among them, the boron problem seems to have a critical meaning. Boron has been found to have a dual effect on the living systems on Earth and the difference between boron deficiency and boron toxicity levels is quite small. The aim of this project is to develop a new generation of RO membranes based on porous graphene or reduced graphene oxide (rGO) able to remove salts from seawater and to reduce boron concentrations in the permeate to the level that meets the drinking or process water requirements, by means of a theoretical approach based on density functional theory and classical molecular dynamics. Computer simulations have been employed to investigate the relationship between the atomic structure of nanoporous graphene or rGO monolayer and its membrane properties in RO applications (i.e. water permeability and resilience at RO pressures). In addition, an emphasis has been given to multilayer nanoporous rGO and rGO flakes based membranes. By means of non-equilibrium MD simulations, we investigated the water transport mechanism permeating through such multilayer membrane focusing on the effect of slit widths and sheet geometries. These simulations allowed us to establish the implications of these graphene based materials as promising membrane properties for desalination plants and as boron filtration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boron%20filtration" title="boron filtration">boron filtration</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20membrane" title=" graphene membrane"> graphene membrane</a>, <a href="https://publications.waset.org/abstracts/search?q=reduced%20graphene%20oxide%20membrane" title=" reduced graphene oxide membrane"> reduced graphene oxide membrane</a> </p> <a href="https://publications.waset.org/abstracts/69154/graphene-based-materials-as-novel-membranes-for-water-desalination-and-boron-separation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69154.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">299</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">445</span> Recovery of Boron from Industrial Wastewater by Chemical Oxo-Precipitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yao-Hui%20Huang">Yao-Hui Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming-Chun%20Yen"> Ming-Chun Yen</a>, <a href="https://publications.waset.org/abstracts/search?q=Jui-Yen%20Lin"> Jui-Yen Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu-Jen%20Shih"> Yu-Jen Shih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work investigated the reclamation of boron in industrial wastewaters by a chemical oxo-precipitation (COP) technique at room temperature. In COP, the boric acid was pretreated with H₂O₂, yielding various perborate anions. Afterwards, calcium chloride was used to efficiently remove boron through precipitation of calcium perborate. The important factors included reacted pH and the molar ratio of [Ca]/[B]. Under conditions of pH 11 and [Ca]/[B] of 1, the boron concentration could be reduced immediately from 600 ppm to 50 ppm in 10 minutes. The boron removal was enhanced with a higher [Ca]/[B], which further reduced boron to 20 ppm in 10 minutes. Nevertheless, the dissolution of carbon dioxide potentially affected the efficacy of COP and increased the boron concentration after 10 minutes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20oxo-precipitation" title="chemical oxo-precipitation">chemical oxo-precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=boron" title=" boron"> boron</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide" title=" carbon dioxide"> carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20peroxide" title=" hydrogen peroxide"> hydrogen peroxide</a> </p> <a href="https://publications.waset.org/abstracts/54161/recovery-of-boron-from-industrial-wastewater-by-chemical-oxo-precipitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54161.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">285</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">444</span> Comparison of Chemical Coagulation and Electrocoagulation for Boron Removal from Synthetic Wastewater Using Aluminium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kartikaningsih%20Danis">Kartikaningsih Danis</a>, <a href="https://publications.waset.org/abstracts/search?q=Yao-Hui%20Huang"> Yao-Hui Huang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various techniques including conventional and advanced have been employed for the boron treatment from water and wastewater. The electrocoagulation involves an electrolytic reactor for coagulation/flotation with aluminium as anode and cathode. There is aluminium as coagulant to be used for removal which may induce secondary pollution in chemical coagulation. The purpose of this study is to investigate and compare the performance between electrocoagulation and chemical coagulation on boron removal from synthetic wastewater. The effect of different parameters, such as pH reaction, coagulant dosage, and initial boron concentration were examined. The results show that the boron removal using chemical coagulation was lower. At the optimum condition (e.g. pH 8 and 0.8 mol coagulant dosage), boron removal efficiencies for chemical coagulation and electrocoagulation were 61% and 91%, respectively. In addition, the electrocoagulation needs no chemical reagents and makes the boron treatment easy for application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boron%20removal" title="boron removal">boron removal</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20coagulation" title=" chemical coagulation"> chemical coagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=aluminum" title=" aluminum"> aluminum</a>, <a href="https://publications.waset.org/abstracts/search?q=electro-coagulation" title=" electro-coagulation "> electro-coagulation </a> </p> <a href="https://publications.waset.org/abstracts/22930/comparison-of-chemical-coagulation-and-electrocoagulation-for-boron-removal-from-synthetic-wastewater-using-aluminium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22930.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">404</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">443</span> Influence of Boron Doping and Thermal Treatment on Internal Friction of Monocrystalline Si1-xGex(x≤0,02) Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=I.%20Kurashvili">I.

COP uses H2O2 to transform boric acid to perborates which can easily precipitate with barium ions at room temperature. However, the generation of the waste sludge that requires sludge/water separation and sludge dewatering is troublesome. This work presents an innovative technology which integrates chemical oxo-precipitation (COP) with fluidized-bed homogeneous granulation (FBHG) to reclaim boron as homogeneous perborate particles. By conducting COP in a fluidized-bed reactor, the barium perborate can be granulated to form homogeneous particles (>1.0 mm) with low water content (< 10%). Under the suitable condition, more than 70% of boron can be recovered from 600 ppm of boron solution and the residual boron is lower than 100 ppm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=barium" title="barium">barium</a>, <a href="https://publications.waset.org/abstracts/search?q=perborate" title=" perborate"> perborate</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20oxo-precipitation" title=" chemical oxo-precipitation"> chemical oxo-precipitation</a>, <a href="https://publications.waset.org/abstracts/search?q=boron%20removal" title=" boron removal"> boron removal</a>, <a href="https://publications.waset.org/abstracts/search?q=fluidized-bed" title=" fluidized-bed"> fluidized-bed</a>, <a href="https://publications.waset.org/abstracts/search?q=granulation" title=" granulation"> granulation</a> </p> <a href="https://publications.waset.org/abstracts/45161/recovery-of-boron-as-homogeneous-perborate-particles-from-synthetic-wastewater-by-integrating-chemical-oxo-precipitation-with-fluidized-bed-homogeneous-granulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45161.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">323</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">441</span> Micro-Filtration with an Inorganic Membrane</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Benyamina">Benyamina</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouldabess"> Ouldabess</a>, <a href="https://publications.waset.org/abstracts/search?q=Bensalah"> Bensalah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to use membrane technique for filtration of a coloring solution. the preparation of the micro-filtration membranes is based on a natural clay powder with a low cost, deposited on macro-porous ceramic supports.

Magnesium borates, which are a sub-class of boron minerals, are useful additive materials for the industries due to their remarkable thermal and mechanical properties. Magnesium borates were obtained hydrothermally at different temperatures.

The electrolytic parameters included pH, current density, and initial boron concentration for optimizing the EC process. Experimental results showed that removal efficiency was increased by elevating pH from 4.0 to 8.0, and then decreased at higher pH. The electrolytic efficacy was not affected by current density. In respect of energy consumption, 1.25 mA/cm2 of current density was acceptable for an effective EC of boron, while increasing boric acid from 10 to 100 ppm-B did not impair removal efficiency too much. Cyclic voltammetry indicated that the oxide film, Ni(OH)2 and NiOOH, at specific overpotentials would result in less weight loss of anode than that predicted by the Faraday&rsquo;s law. The optimal conditions under which 99.2% of boron was removed and less than 1 ppm-B remained in the electrolyte would be pH 8, four pairs of electrodes, and 1.25 mA/cm2 in 120 min as treating wastewaters containing 10 ppm-B. XRD and SEM characterization suggested that the granular crystallites of hydroxide precipitates was composed of theophrastite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=borohydrides" title="borohydrides">borohydrides</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20generation" title=" hydrogen generation"> hydrogen generation</a>, <a href="https://publications.waset.org/abstracts/search?q=NiOOH" title=" NiOOH"> NiOOH</a>, <a href="https://publications.waset.org/abstracts/search?q=electrocoagulation" title=" electrocoagulation"> electrocoagulation</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20voltammetry" title=" cyclic voltammetry"> cyclic voltammetry</a>, <a href="https://publications.waset.org/abstracts/search?q=boron%20removal" title=" boron removal"> boron removal</a> </p> <a href="https://publications.waset.org/abstracts/45835/electrocoagulation-of-nioh2niooh-for-the-removal-of-boron-using-nickel-foam-as-sacrificial-anode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45835.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">260</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">437</span> A Fluorescent Polymeric Boron Sensor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soner%20Cubuk">Soner Cubuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirgul%20Kosif"> Mirgul Kosif</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Vezir%20Kahraman"> M.

Suitable methods for the determination of boron have been proposed, including acid - base titrimetric, inductively coupled plasma emission spectroscopy flame atomic absorption and spectrophotometric. However, the above methods have some disadvantages such as long analysis times, requirement of corrosive media such as concentrated sulphuric acid and multi-step sample preparation requirements and time-consuming procedures. In this study, a selective and reusable fluorescent sensor for boron based on glycosyloxyethyl methacrylate was prepared by photopolymerization. The response characteristics such as response time, pH, linear range, limit of detection were systematically investigated. The excitation/emission maxima of the membrane were at 378/423 nm, respectively. The approximate response time was measured as 50 sec. In addition, sensor had a very low limit of detection which was 0.3 ppb. The sensor was successfully used for the determination of boron in water samples with satisfactory results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boron" title="boron">boron</a>, <a href="https://publications.waset.org/abstracts/search?q=fluorescence" title=" fluorescence"> fluorescence</a>, <a href="https://publications.waset.org/abstracts/search?q=photopolymerization" title=" photopolymerization"> photopolymerization</a>, <a href="https://publications.waset.org/abstracts/search?q=polymeric%20sensor" title=" polymeric sensor"> polymeric sensor</a> </p> <a href="https://publications.waset.org/abstracts/41973/a-fluorescent-polymeric-boron-sensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41973.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">283</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">436</span> Mechanochemical Behaviour of Aluminium–Boron Oxide–Melamine Ternary System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ismail%20Seckin%20Cardakli">Ismail Seckin Cardakli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Engin%20Kocadagistan"> Mustafa Engin Kocadagistan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ersin%20Arslan"> Ersin Arslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, mechanochemical behaviour of aluminium - boron oxide - melamine ternary system was investigated by high energy ball milling.

These superior properties enable to use it in several high-tech areas from electronics to nuclear industry and especially in high temperature metallurgy. Amorphous boron and crystalline boron have different application areas. Amorphous boron powder (directly amorphous and/or α-rhombohedral) is preferred in rocket firing, airbag inflating and in fabrication of superconducting MgB2 wires. The conventional ways to produce elemental boron with a purity of 85 pct to 95 prc are metallothermic reduction, fused salt electrolysis and mechanochemical synthesis; but the only way to produce high-purity boron powders is Chemical Vapour Deposition (Hot Surface CVD). In this study; amorphous boron powders with a minimum purity of 99,9 prc were synthesized in quartz tubes using BCl3-H2 gas mixture by CVD. Process conditions based on temperature and gas flow rate were determined. Thermodynamical interpretation of BCl3-H2 system for different temperatures and molar rates were performed using Fact Sage software. The characterization of powders was examined by using Xray diffraction (XRD), Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM), Stereo Microscope (SM), Helium gas pycnometer analysis. The purities of final products were determined by titration after lime fusion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amorphous%20boron" title="amorphous boron">amorphous boron</a>, <a href="https://publications.waset.org/abstracts/search?q=CVD" title=" CVD"> CVD</a>, <a href="https://publications.waset.org/abstracts/search?q=powder%20production" title=" powder production"> powder production</a>, <a href="https://publications.waset.org/abstracts/search?q=powder%20characterization" title=" powder characterization"> powder characterization</a> </p> <a href="https://publications.waset.org/abstracts/57325/production-of-amorphous-boron-powder-via-chemical-vapor-deposition-cvd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57325.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">218</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">434</span> Effects of Boron Compounds in Rabbits Fed High Protein and Energy Diet: A Metabolomic and Transcriptomic Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nuri%20Ba%C5%9Fp%C4%B1nar">Nuri Başpınar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Ba%C5%9Fo%C4%9Flu"> Abdullah Başoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zg%C3%BCr%20%C3%96zdemir"> Özgür Özdemir</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%87a%C4%9Flayan%20%C3%96zel"> Çağlayan Özel</a>, <a href="https://publications.waset.org/abstracts/search?q=FundaTerzi"> FundaTerzi</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zg%C3%BCr%20Yaman"> Özgür Yaman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Current research is targeting new molecular mechanisms that underlie non-alcoholic fatty liver disease (NAFLD) and associated metabolic disorders like nonalcoholic steatohepatitis (NASH). Forty New Zealand White rabbits have been used and fed a high protein (HP) and energy diet based on grains and containing 11.76 MJ/kg. Boron added to 3 experimental groups’ drinking waters (30 mg boron/L) as boron compounds. Biochemical analysis including boron levels, and nuclear magnetic resonance (NMR) based metabolomics evaluation, and mRNA expression of peroxisome proliferator-activated receptor (PPAR) family were performed. LDL-cholesterol concentrations alone were decreased in all the experimental groups. Boron levels in serum and feces were increased. Content of acetate was in about 2x higher for anhydrous borax group, at least 3x higher for boric acid group. PPARα mRNA expression was significantly decreased in boric acid group. Anhydrous borax attenuated mRNA levels of PPARα, which was further suppressed by boric acid. Boron supplementation decreased the degenerative alterations in hepatocytes. Except borax group other boron groups did not have a pronounced change in tubular epithels of kidney. In conclusion, high protein and energy diet leads hepatocytes’ degenerative changes which can be prevented by boron supplementation. Boric acid seems to precede in this effectiveness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=high%20protein%20and%20energy%20diet" title="high protein and energy diet">high protein and energy diet</a>, <a href="https://publications.waset.org/abstracts/search?q=boron" title=" boron"> boron</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolomics" title=" metabolomics"> metabolomics</a>, <a href="https://publications.waset.org/abstracts/search?q=transcriptomic" title=" transcriptomic "> transcriptomic </a> </p> <a href="https://publications.waset.org/abstracts/28491/effects-of-boron-compounds-in-rabbits-fed-high-protein-and-energy-diet-a-metabolomic-and-transcriptomic-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28491.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">627</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">433</span> Influence of Sulphur and Boron on Growth, Quality Parameters and Productivity of Soybean (Glycine Max (L.)

The object was to evaluate the impact of sulphur and boron on growth, development, grain yield and physiological aspects of soybean variety MAUS-81. Nine treatments consisted of three levels of sulphur i.e. 20, 30 and 40 Kg/ha as well as three levels boron i.e.10, 15 and 20 kg boron/ha and the combinations of these two mineral elements i.e. Sulphur @30 kg/ha + Borax @15 kg/ha and Sulphur @40 kg/ha + Borax @ 20 kg/ha with one control treatment in Randomized Block Design (RBD) with three replications. The effect of sulphur and boron on various growth parameters of soybean like relative growth rate (RGR) and net assimilation rate (NAR) were remained statistically on par with each other. However, the application of higher dose of Sulphur @40 kg/ha + Borax @ 20 kg/ha enhanced significantly all the growth parameters. Application of the nutrients increased the dry matter accumulation of the crop plant and hence, other growth indices like RGR and NAR also increased significantly. RGR and NAR values were recorded highest at the initial crop growth stages and decline thereafter. The application of sulphur @40 kg/ha + Borax @ 20 kg/ha recorded significantly higher content of chlorophyll ‘a’ than rest of the treatments and chlorophyll ‘b’ observed higher in boron @15 kg/ha as well as boron@20 kg/ha, whereas total chlorophyll content was maximum in sulphur @40 kg/ha. Oil content was not influenced significantly due to above fertilization. The highest seed yield and total biological yield were obtained with combination of Sulphur @40 kg/ha + Borax @ 20 kg/ha, single sulphur and boron application also showed a significant effect on seed and biological yield. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boron" title="boron">boron</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean%20and%20sulphur" title=" soybean and sulphur"> soybean and sulphur</a> </p> <a href="https://publications.waset.org/abstracts/21799/influence-of-sulphur-and-boron-on-growth-quality-parameters-and-productivity-of-soybean-glycine-max-l-merrill" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21799.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">405</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">432</span> Enhancing Water Purification with Angiosperm Xylem Filters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yinan%20Zhou">Yinan Zhou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One in four people in the world still lack access to clean drinking water, and there is a current lack of cost-effective ways for water-scarce regions to access it.

Four angiosperms that are found in China and around Asia were subject to three tests to test their filtration capacity: ink water filtration, creek water filtration, and microparticle filtration. Analysis of the experiments demonstrated that Celtis Sinensis was able to produce one of the clearest solutions, filter out large debris and bacteria, and reject microparticles almost completely. Celtis Sinensis proves that angiosperm xylem filters are also competent filter candidates and, due to their availability in China, can be used as a nearby source of water filtration. Further research should be done on scaling production to a larger scale and also on the filtration of viruses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=xylem%20filter" title="xylem filter">xylem filter</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=China" title=" China"> China</a>, <a href="https://publications.waset.org/abstracts/search?q=angiosperms" title=" angiosperms"> angiosperms</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteria" title=" bacteria"> bacteria</a> </p> <a href="https://publications.waset.org/abstracts/193135/enhancing-water-purification-with-angiosperm-xylem-filters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193135.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">8</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">431</span> Liquid Phase Sintering of Boron-Alloyed Powder Metallurgy Stainless Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ming-Wei%20Wu">Ming-Wei Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Zih-Jie%20Lin"> Zih-Jie Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Liquid phase sintering (LPS) is a feasible means for decreasing the porosity of powder metallurgy (PM) Fe-based material without substantially increase the production cost.

The results showed that adding 0.6 wt% boron can obviously promote the LPS due to a eutectic reaction and increase the sintered density of 410 stainless steel.

The composites are fabricated with the stir casting process. To avoid gas entrapment during mixing and ensure nonporous composites, partial vacuum is adapted during particle feeding and stirring. Poor wettability of boron carbide with liquid aluminum hinders particle incorporation, but alloying elements such as magnesium and titanium could improve wettability and thus particle incorporation. Next to alloying elements, adapted stirring parameters and impeller geometries improve particle incorporation and enable homogenous particle distribution and high particle volume fractions of boron carbide. AMCs with up to 15 vol.% of boron carbide particles are produced via melt stirring, resulting in an increase in stiffness and strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminum%20matrix%20composites" title="aluminum matrix composites">aluminum matrix composites</a>, <a href="https://publications.waset.org/abstracts/search?q=boron%20carbide" title=" boron carbide"> boron carbide</a>, <a href="https://publications.waset.org/abstracts/search?q=stiffness" title=" stiffness"> stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=stir%20casting" title=" stir casting"> stir casting</a> </p> <a href="https://publications.waset.org/abstracts/64924/effect-of-alloying-elements-on-particle-incorporation-of-boron-carbide-reinforced-aluminum-matrix-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64924.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">308</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">427</span> Investigation of Additives&#039; Corrosion Inhibition Effects on Dye</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Bilal%20Ozturk">Abdullah Bilal Ozturk</a>, <a href="https://publications.waset.org/abstracts/search?q=Nil%20Acarali"> Nil Acarali</a>, <a href="https://publications.waset.org/abstracts/search?q=Hediye%20Irem%20Ozgunduz"> Hediye Irem Ozgunduz</a>, <a href="https://publications.waset.org/abstracts/search?q=Hava%20Gizem%20Kandilci"> Hava Gizem Kandilci</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanifi%20Sarac"> Hanifi Sarac</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, zeolite, shellac and different boron chemicals were used as additive to dye and effects were comprehensively investigated.

Moreover, it has a big cross section for neutron absorption and therefore can be employed in nuclear based applications. However, an efficient attachment of boron carbide to a metal such as aluminum can be very challenging, mainly because of the formation of aluminum-carbon bonds that are unstable in humid environment, the affinity of oxygen to the metal and the different thermal expansion coefficients of the two materials that may cause internal stresses and a subsequent failure of the bond. Here, we aimed to achieving a strong and a durable attachment between the boron carbide coating and the aluminum substrate. For this purpose, we applied Ti as a thin intermediate layer that provides a gradual change in the thermal expansion coefficients of the configured layers. This layer is continuous and therefore prevents the formation of aluminum-carbon bonds. Boron carbide coatings with a thickness of 1-5 µm were deposited on the aluminum substrate by pulse-DC magnetron sputtering. Prior to the deposition of the boron carbide layer, the surface was pretreated by energetic ion plasma followed by deposition of the Ti intermediate adhesive layer in a continuous process. The properties of the Ti intermediate layer were adjusted by the bias applied to the substrate. The boron carbide/aluminum bond was evaluated by various methods and complementary techniques, such as SEM/EDS, XRD, XPS, FTIR spectroscopy and Glow Discharge Spectroscopy (GDS), in order to explore the structure, composition and the properties of the layers and to study the adherence mechanism of the boron carbide/aluminum contact. Based on the interfacial bond characteristics, we propose a desirable solution for improved adhesion of boron carbide to aluminum using a highly efficient intermediate adhesive layer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adhesion" title="adhesion">adhesion</a>, <a href="https://publications.waset.org/abstracts/search?q=boron%20carbide%20coatings" title=" boron carbide coatings"> boron carbide coatings</a>, <a href="https://publications.waset.org/abstracts/search?q=ceramic%2Fmetal%20bond" title=" ceramic/metal bond"> ceramic/metal bond</a>, <a href="https://publications.waset.org/abstracts/search?q=intermediate%20layer" title=" intermediate layer"> intermediate layer</a>, <a href="https://publications.waset.org/abstracts/search?q=pulsed-DC%20magnetron%20sputtering" title=" pulsed-DC magnetron sputtering"> pulsed-DC magnetron sputtering</a> </p> <a href="https://publications.waset.org/abstracts/107246/adhesion-enhancement-of-boron-carbide-coatings-on-aluminum-substrates-utilizing-an-intermediate-adhesive-layer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/107246.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">164</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">425</span> Development and Analysis of SFR Control Rod Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lenka%20Duj%C4%8D%C3%ADkov%C3%A1">Lenka Dujčíková</a>, <a href="https://publications.waset.org/abstracts/search?q=Laurent%20Buiron"> Laurent Buiron</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%A1n%20Ha%C5%A1%C4%8D%C3%ADk"> Ján Haščík</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study is dedicated to safety management of SFR CAPRA core with CFV design improvements.

At first, the European Fast Reactor (EFR) control rod design with high-enriched boron carbide B4C as absorber material was tested. Considering costly and difficult enrichment process, usage of natural boron carbide absorbator is desired. Obviously, the use of natural boron leads to CR worth reduction.

Using a graphene/h-BN/TiN (channel/dielectric/gate) stack, key material properties of h-BN were investigated i.e. dielectric strength and tunneling behavior. Work function difference between graphene and TiN results in spontaneous p-doping of graphene through a multi-layer h-BN flake. However, at high levels of current stress, n-doping of graphene is observed, possibly due to the charge transfer across the thin h-BN multi layer. Neither Direct Tunneling (DT) nor Fowler-Nordheim Tunneling (FNT) was observed in TiN/h-BN/Au hetero structures with h-BN showing two distinct volatile conduction states before breakdown. Hexagonal boron nitride emerges as a material of choice for gate dielectrics in GFETs because of robust dielectric properties and high tunneling barrier. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphene" title="graphene">graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=transistors" title=" transistors"> transistors</a>, <a href="https://publications.waset.org/abstracts/search?q=conduction" title=" conduction"> conduction</a>, <a href="https://publications.waset.org/abstracts/search?q=hexagonal%20boron%20nitride" title=" hexagonal boron nitride"> hexagonal boron nitride</a>, <a href="https://publications.waset.org/abstracts/search?q=dielectric%20strength" title=" dielectric strength"> dielectric strength</a>, <a href="https://publications.waset.org/abstracts/search?q=tunneling" title=" tunneling"> tunneling</a> </p> <a href="https://publications.waset.org/abstracts/22593/dielectric-behavior-of-2d-layered-insulator-hexagonal-boron-nitride" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22593.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">365</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">423</span> Valorization of Natural Vegetable Substances from Tunisia: Purification of Two Food Additives, Anthocyanins and Locust Bean Gum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Bouzouita">N.

For this purpose, cast materials were alloyed by melting in an induction furnace to include boron with the rates of 0 ppm, 15 ppm, and 50 ppm (wt.) and were formed in the dimensions of 150x200x150 mm by casting into the sand mould. Homogenization heat treatment was applied to the specimens at 1150˚C for 7 hours. Then all specimens were austenitized at 930˚C for 1 hour, quenched in the polymer solution and tempered at 650˚C for 1 hour. Microstructures of the specimens were investigated by using light microscope and SEM to determine the effect of boron and heat treatment conditions. Changes in microstructure properties and material hardness were obtained due to increasing boron content and heat treatment conditions after microstructure investigations and hardness tests. Wear tests were carried out using a pin-on-disc tribometer under dry sliding conditions. Charpy V notch impact test was performed to determine the toughness properties of the specimens.

Overcoming this problem has attracted interest and prompted research on the use of PM filtration in commercial buildings and homes to be carried out. The consensus is that tangible health benefits can result from the use of PM filters in most urban environments, to clean up the building’s fresh air supply and thereby reduce exposure of residents to airborne PM. The authors have investigated and are developing a new large-scale Permeodynamic Filtration Technology (PFT) capable of permanently filtering and removing airborne PMs from outdoor spaces, thus also benefiting internal spaces such as the interiors of buildings. Theoretical models were developed, and laboratory trials carried out to determine, and validate through measurement permeodynamic filtration efficiency and pressure drop as functions of PM particle size distributions. The conclusion is that PFT offers a potentially viable, cost effective end of pipe solution to the problem of airborne PM. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=air%20filtration" title="air filtration">air filtration</a>, <a href="https://publications.waset.org/abstracts/search?q=particulate%20matter" title=" particulate matter"> particulate matter</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20size%20distribution" title=" particle size distribution"> particle size distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=permeodynamic" title=" permeodynamic "> permeodynamic </a> </p> <a href="https://publications.waset.org/abstracts/99556/permeodynamic-particulate-matter-filtration-for-improved-air-quality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99556.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">204</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">420</span> Investigation Particle Behavior in Gas-Solid Filtration with Electrostatic Discharge in a Hybrid System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fl%C3%A1via%20M.%20Oliveira">Flávia M.

It is found that the increase of boron composition alters the BGaAs epilayers transport properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photothermal%20defelction%20technique" title="photothermal defelction technique">photothermal defelction technique</a>, <a href="https://publications.waset.org/abstracts/search?q=two%20layer%20model" title=" two layer model"> two layer model</a>, <a href="https://publications.waset.org/abstracts/search?q=BGaAs%2FGaAs%20alloys" title=" BGaAs/GaAs alloys"> BGaAs/GaAs alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=boron%20composition" title=" boron composition"> boron composition</a> </p> <a href="https://publications.waset.org/abstracts/10638/two-layer-photo-thermal-deflection-model-to-investigate-the-electronic-properties-in-bgaasgaas-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10638.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">301</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">418</span> Corrosion Resistance of Mild Steel Coated with Different Polyimides/h-Boron Nitride Composite Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tariku%20Nefo%20Duke">Tariku Nefo Duke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Herein, we synthesized three PIs/h-boron nitride composite films for corrosion resistance of mild steel material. The structures of these three polyimide/h-boron nitride composite films were confirmed using (FTIR, 1H NMR, 13C NMR, and 2D NMR) spectroscopy techniques. The synthesized PIs composite films have high mechanical properties, thermal stability, high glass-transition temperature (Tg), and insulating properties. It has been shown that the presence of electroactive TiO2, SiO2, and h-BN, in polymer coatings effectively inhibits corrosion. The h-BN displays an admirable anti-corrosion barrier for the 6F-OD and BT-OD films. PI/ h-BN composite films of 6F-OD exhibited better resistance to water vapor, high corrosion resistance, and positive corrosion voltage. Only four wt. percentage of h-BN in the composite is adequate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polyimide" title="polyimide">polyimide</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20resistance" title=" corrosion resistance"> corrosion resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=electroactive" title=" electroactive"> electroactive</a>, <a href="https://publications.waset.org/abstracts/search?q=Tg" title=" Tg"> Tg</a> </p> <a href="https://publications.waset.org/abstracts/149868/corrosion-resistance-of-mild-steel-coated-with-different-polyimidesh-boron-nitride-composite-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149868.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">201</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">417</span> Synthesis of Mg/B Containing Compound in a Modified Microwave Oven</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCl%C5%9Fah%20%C3%87elik%20G%C3%BCl">Gülşah Çelik Gül</a>, <a href="https://publications.waset.org/abstracts/search?q=Figen%20Kurtulu%C5%9F"> Figen Kurtuluş</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Magnesium containing boron compounds with hexagonal structure have been drawn much attention due to their superconductive nature. The main target of this work is new modified microwave oven by on our own has an ability about passing through a gas in the oven medium for attainment of oxygen-free compounds such as c-BN. &nbsp;Mg containing boride was synthesized by modified-microwave method under nitrogen atmosphere using amorphous boron and magnesium source in appropriate molar ratio. Microwave oven with oxygen free environment has been modified to aimed to obtain magnesium boride without oxygen. Characterizations were done by powder X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy. Mg containing boride, generally named magnesium boride, with amorphous character without oxygen is obtained via designed microwave oven system. <p class="card-text"><strong>Keywords:</strong> <a
