Polyacrylonitrile/N,N-dimethylformamide (PAN/DMF) solution has been prepared and the amount of silver nitrate has been adjusted to PAN weight. Silver nano-particles were obtained from reduction of silver ions into silver nano-particles by chemical reduction by hydrazine hydroxide (N2H5OH). The different amount of silver salt was loaded into polymer matrix to obtain polyacrylonitrile composite nano-fiber containing silver nano-particles. The effect of the amount of silver nano-particles on the properties of composite nano-fiber web was investigated. Electrical conductivity, mechanical properties, thermal properties were examined by Microtest LCR Meter 6370 (0.01 mΩ-100 MΩ), tensile tester, differential scanning calorimeter DSC (Q10) and SEM, respectively. Also, antimicrobial efficiency test (ASTM E2149-10) was done against Staphylococcus aureus bacteria. It has been seen that breaking strength, conductivity, antimicrobial effect, enthalpy during cyclization increase by use of silver nano-particles while the diameter of nano-fiber decreases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20polyacrylonitrile%20nanofiber" title="composite polyacrylonitrile nanofiber">composite polyacrylonitrile nanofiber</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20conductivity" title=" electrical conductivity"> electrical conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20properties" title=" thermal properties"> thermal properties</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/7504/investigation-of-electrical-thermal-and-structural-properties-on-polyacrylonitrile-nano-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7504.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">418</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">3013</span> Production and Characterization of Sol-Enhanced Zn-Ni-Al2O3 Nano Composite Coating</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soroor%20Ghaziof">Soroor Ghaziof</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Gao"> Wei Gao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sol-enhanced Zn-Ni-Al2O3 nano-composite coatings were electroplated on mild steel by our newly developed sol-enhanced electroplating method.

In this method, transparent Al2O3 sol was added into the acidic Zn-Ni bath to produced Zn-Ni-Al2O3 nano-composite coatings.

Results from XRD tests showed that the structure of all coatings was single γ-Ni5Zn21 phase. Cyclic voltammetry results showed that the electrodeposition overpotential was lower in the presence of alumina sol in the bath, and caused the reduction potential of Zn-Ni to shift to more positive values.

The behavior of the traditional two-phase composite has been compared with the one of a new three-phase composite where the epoxy matrix was modified by addition of a 3% weight fraction of montmorillonite nano-particles. Two different types of nano-clays, Cloisite® 30B and RXG7000, produced by Southern Clay Products Inc., have been considered. Three-point bending tests, both monotonic and cyclic, were carried out. A strong reduction of the ultimate flexural strength upon nano-modification has been observed in quasi-static tests. Fatigue tests yielded a smaller strength loss. In both quasi-static and fatigue tests a more pronounced tendency to delamination has been noticed in three-phase composites, especially in the case of 30B nano-clay, with respect to the standard two-phase glass fiber composite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bending%20fatigue" title="bending fatigue">bending fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy%20resin" title=" epoxy resin"> epoxy resin</a>, <a href="https://publications.waset.org/abstracts/search?q=glass%20fiber" title=" glass fiber"> glass fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=montmorillonite" title=" montmorillonite"> montmorillonite</a> </p> <a href="https://publications.waset.org/abstracts/2069/on-the-fatigue-behavior-of-a-triphasic-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2069.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">446</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">3008</span> The Elastic Field of a Nano-Pore, and the Effective Modulus of Composites with Nano-Pores</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xin%20Chen">Xin Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Moxiao%20Li"> Moxiao Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Xuechao%20Sun"> Xuechao Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Fei%20Ti"> Fei Ti</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaobao%20Liu"> Shaobao Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Feng%20Xu"> Feng Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Tian%20Jian%20Lu"> Tian Jian Lu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The composite materials with pores have the characteristics of light weight, sound insulation, and heat insulation, and have broad prospects in many fields, including aerospace. In general, the stiffness of such composite is less than the stiffness of the matrix material, limiting their applications. In this paper, we establish a theoretical model to analyze the deformation mechanism of a nano-pore. The interface between the pores and matrix material is described by the Gurtin-Murdoch model. By considering scale effect related with current deformation, we estimate the effective mechanical properties (e.g., effective shear modulus and bulk modulus) of a composite with nano-pores. Due to the scale effect, the elastic field in the composite was changed and local hardening was observed around the nano-pore, and the effective shear modulus and effective bulk modulus were found to be a function of the surface energy. The effective shear modulus increase with the surface energy and decrease with the size of the nano-pores, and the effective bulk modulus decrease with the surface energy and increase with the size of the nano-pores. These results have potential applications in the nanocomposite mechanics and aerospace field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composite%20mechanics" title="composite mechanics">composite mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-inhomogeneity" title=" nano-inhomogeneity"> nano-inhomogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-pores" title=" nano-pores"> nano-pores</a>, <a href="https://publications.waset.org/abstracts/search?q=scale%20effect" title=" scale effect"> scale effect</a> </p> <a href="https://publications.waset.org/abstracts/109464/the-elastic-field-of-a-nano-pore-and-the-effective-modulus-of-composites-with-nano-pores" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109464.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">134</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">3007</span> Application of Electrochemically Prepared PPy/MWCNT:MnO2 Nano-Composite Film in Microbial Fuel Cells for Sustainable Power Generation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajeev%20jain">Rajeev jain</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20C.%20Tiwari"> D.

The nano-composite was structurally characterized by FTIR, SEM, TEM and UV-Vis studies. Nano-composite was also characterized by cyclic voltammetry (CV), current voltage measurements (I-V) and the optical band gaps of film were evaluated from UV-Vis absorption studies. The PPy/MWCNT:MnO2 nano-composite was used as anode in microbial fuel cell (MFC) for sewage waste water treatment, power and coulombic efficiency measurement. The prepared electrode showed good electrical conductivity (0.1185 S m-1). This was also supported by band gap measurements (direct 0.8 eV, indirect 1.3 eV).

The high aspect ratio and unique surface features of graphene resulted in significant improvements of the nano composites properties. In this study, nano composite fibres made of cellulose and graphene nano platelets were wet spun from solution by using ionic liquid, 1-ethyl-3-methylimidazolium acetate (EMIMAc) as solvent. The effect of graphene loading on the thermal and electrical properties of the nanocomposite fibres was investigated. The nano composite fibres characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) analysis. XRD analysis revealed a cellulose II crystalline structure for regenerated cellulose and the nano composite fibres. SEM images showed a homogenous morphology and round cross section for the nano composite fibres along with well dispersion of graphene nano platelets in regenerated cellulose matrix. The incorporation of graphene into cellulose matrix generated electrical conductivity. At 6 wt. % of graphene, the electrical conductivity was 4.7 × 10-4 S/cm. The nano composite fibres also showed considerable improvements in thermal stability and char yield compared to pure regenerated cellulose fibres. This work provides a facile and environmentally friendly method of preparing nano composite fibres based on cellulose and graphene nano platelets that can find several applications in cellulose-based carbon fibres, conductive fibres, apparel, etc. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title="nanocomposite">nanocomposite</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene%20nanoplatelets" title=" graphene nanoplatelets"> graphene nanoplatelets</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerated%20cellulose" title=" regenerated cellulose"> regenerated cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20properties" title=" electrical properties"> electrical properties</a> </p> <a href="https://publications.waset.org/abstracts/30979/electrical-properties-of-nanocomposite-fibres-based-on-cellulose-and-graphene-nanoplatelets-prepared-using-ionic-liquids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30979.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">350</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">3005</span> Investigation of Tribological Behavior of Electrodeposited Cr, Co-Cr and Co-Cr/Tio2 Nano-Composite Coatings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Mahdavi">S.

Dc electrodeposition was used to produce Cr, Co-Cr and Co-Cr/TiO2 nano-composite coatings from Cr(III) based electrolytes onto 316L SS substrates. The effects of TiO2 nano-particles concentration on co-deposition of these particles along with Cr content and microhardness of the coatings were investigated. Morphology of the Cr, Co-Cr and Co-Cr/TiO2 coatings besides their tribological behavior were studied. The results showed that increment of TiO2 nano-particles concentration from 0 to 30 g L-1 in the bath increased their co-deposition and Cr content of the coatings from 0 to 3.5 wt.% and from 23.7 to 31.2 wt.%, respectively. Microhardness of Cr coating was about 920 Hv which was higher than Co-Cr and even Co-Cr/TiO2 films. Microhardness of Co-Cr and Co-Cr/TiO2 coatings were improved by increasing their Cr and TiO2 content. All the coatings had nodular morphology and contained microcracks. Nodules sizes and the number of microcracks in the alloy and composite coatings were lower than the Cr film. Wear results revealed that the Co-Cr/TiO2 coating had the lowest wear loss between all the samples, while the Cr film had the worst wear resistance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Co-Cr%20alloy" title="Co-Cr alloy">Co-Cr alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodeposition" title=" electrodeposition"> electrodeposition</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-composite" title=" nano-composite"> nano-composite</a>, <a href="https://publications.waset.org/abstracts/search?q=tribological%20behavior" title=" tribological behavior"> tribological behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=trivalent%20chromium" title=" trivalent chromium"> trivalent chromium</a> </p> <a href="https://publications.waset.org/abstracts/24529/investigation-of-tribological-behavior-of-electrodeposited-cr-co-cr-and-co-crtio2-nano-composite-coatings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24529.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">487</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">3004</span> Behavior of Fibre Reinforced Polymer Composite with Nano-Ceramic Particle under Ballistic Impact and Quasi-Static Punch-Shear Loading </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Rajalakshmi">K.

This study aimed to compare the microleakage and interfacial morphology of flowable nanocomposites and conventional pit and fissure sealants. 60 extracted intact and caries-free permanent mandibular third molars. The teeth were randomly divided into three groups (n = 20) according to the material used for pit and fissure sealant. Group I: Unfilled resin-based pits and fissure sealant, Group II: Unfilled resin-based pits and fissure sealant with bond and Group III: Nano flowable composite resin with bond. The results showed that nano-flowable composite was significantly better than the conventional sealants groups p = 0.000. As well there was better as well, there were gaps between sealants and the tooth surfaces in groups I and II, but for group III, there was close contact between the nano-flowable composite and tooth surfaces.

The sol-gel followed by autocombustion process was used for synthesis of Mn0.8Zn0.2Fe2O4 ferrite. 3 wt.% of mechanically milled ferrite was mixed with Fe3Si powder alloy. Mixed micro-nano powder system was homogenized by the Resonant Acoustic Mixing using ResodynLabRAM Mixer. This non-invasive homogenization technique was used to preserve spherical morphology of Fe3Si powder particles. Uniaxial cold pressing in the closed die at pressure 600 MPa was applied to obtain a compact sample. Microwave sintering of green compact was realized at 800°C, 20 minutes, in air. Density of the powders and composite was measured by Hepycnometry. Impulse excitation method was used to measure elastic properties of sintered composite. Mechanical properties were evaluated by measurement of transverse rupture strength (TRS) and Vickers hardness (HV). Resistivity was measured by 4 point probe method. Ferrite phase distribution in volume of the composite was documented by metallographic analysis. It has been found that nano-ferrite particle distributed among micro- particles of Fe3Si powder alloy led to high relative density (~93%) and suitable mechanical properties (TRS >100 MPa, HV ~1GPa, E-modulus ~140 GPa) of the composite.

Thus, to extend the use of composites in more varied application, one of the actual barrier is their poor electrical conductivities. In the case of carbon fiber composites, organic matrix are in charge of the insulating properties of the resulting composite. However, studying the properties of continuous carbon fiber nano-filled composites is less investigated. This work tends to characterize the effect of carbon black nano-fillers on the properties of the woven carbon fiber composites. First of all, SEM observations were performed to localize the nano-particles. It showed that particles penetrated on the fiber zone (figure1). In fact, by reaching the fiber zone, the carbon black nano-fillers created network connectivity between fibers which means an easy pathway for the current. It explains the noticed improvement of the electrical conductivity of the composites by adding carbon black. This test was performed with the four points electrical circuit. It shows that electrical conductivity of 'neat' matrix composite passed from 80S/cm to 150S/cm by adding 9wt% of carbon black and to 250S/cm by adding 17wt% of the same nano-filler. Thanks to these results, the use of this composite as a strain gauge might be possible. By the way, the study of the influence of a mechanical excitation (flexion, tensile) on the electrical properties of the composite by recording the variance of an electrical current passing through the material during the mechanical testing is possible. Three different configuration were performed depending on the rate of carbon black used as nano-filler. These investigation could lead to develop an auto-instrumented material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20fibers%20composites" title="carbon fibers composites">carbon fibers composites</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-fillers" title=" nano-fillers"> nano-fillers</a>, <a href="https://publications.waset.org/abstracts/search?q=strain-sensors" title=" strain-sensors"> strain-sensors</a>, <a href="https://publications.waset.org/abstracts/search?q=auto-instrumented" title=" auto-instrumented"> auto-instrumented</a> </p> <a href="https://publications.waset.org/abstracts/46982/nano-filled-matrix-reinforced-by-woven-carbon-fibers-used-as-a-sensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46982.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">411</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">2996</span> Use of Nanoclay in Various Modified Polyolefins</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michael%20Tup%C3%BD">Michael Tupý</a>, <a href="https://publications.waset.org/abstracts/search?q=Alice%20Tesa%C5%99%C3%ADkov%C3%A1-Svobodov%C3%A1"> Alice Tesaříková-Svobodová</a>, <a href="https://publications.waset.org/abstracts/search?q=Dagmar%20M%C4%9B%C5%99%C3%ADnsk%C3%A1"> Dagmar Měřínská</a>, <a href="https://publications.waset.org/abstracts/search?q=V%C3%ADt%20Petr%C3%A1nek"> Vít Petránek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Polyethylene (PE), Polypropylene (PP), Polyethylene (vinyl acetate) (EVA) and Surlyn (modif-PE) nano composite samples were prepared with montmorillonite fillers Cloisite 93A and Dellite 67G.

This creation is starting up a new revolution into the world of materials. Nano composites are similar to traditional composite of a polymer blend and filler with at least one nano-scopic dimension. In our project, we worked with nano composites of biodegradable polymer: polycaprolactone, combined with nano-clay (Maghnite) and with different nano-organo-clays. These nano composites have been prepared by melt mixture method. The advantage of this polymer is its degradability and bio compatibility. A study of the relationship between development, micro structure and physico chemical properties of nano composites, clays modified with 3-aminopropyltriethoxysilane (APTES) and Hexadecyltriméthy ammonium bromide (CTAB) and untreated clays were made.

Thermal studies were conducted, as it understanding is vital for preliminary development of new polymeric systems. Thermal analysis of nano composite was conducted using thermo gravimetric analysis (TGA), and differential scanning calorimetry (DSC). Major finding of TGA indicated two main stages of degradation process found at (350 ± 25 oC) and (480 ± 25 oC) respectively. Nano metal filler expressed better fire resistance as it stand over high degree of temperature. Furthermore, DSC analysis provided a stable glass temperature around 51 (±1 oC) and captured double melting point at 84 (±2 oC) and 108 (±2 oC). This binary melting point reflects the modification of nano filler to the polymer matrix forming melting crystals of folded and extended chain. The percent crystallinity of the samples grew vividly with increasing filler content. Overall, increasing the filler loading improved the degradation temperature and weight loss evidently and a better process and phase stability was captured in DSC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermal%20properties" title="thermal properties">thermal properties</a>, <a href="https://publications.waset.org/abstracts/search?q=nano%20MH" title=" nano MH"> nano MH</a>, <a href="https://publications.waset.org/abstracts/search?q=nano%20particles" title=" nano particles"> nano particles</a>, <a href="https://publications.waset.org/abstracts/search?q=cable%20and%20wire" title=" cable and wire"> cable and wire</a>, <a href="https://publications.waset.org/abstracts/search?q=LDPE%2FEVA" title=" LDPE/EVA"> LDPE/EVA</a> </p> <a href="https://publications.waset.org/abstracts/17357/the-thermal-properties-of-nano-magnesium-hydroxide-blended-with-ldpeevairganox1010-for-insulator-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17357.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">451</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">2992</span> Magnetoelectric Coupling in Hetero-Structured Nano-Composite of BST-BLFM Films</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Navneet%20Dabra">Navneet Dabra</a>, <a href="https://publications.waset.org/abstracts/search?q=Jasbir%20S.%20HUndal"> Jasbir S.

We hypothesized that nano-sized Akermanite (AM) would mimic more efficiently the nanocrystal structure and function of natural bone apatite, owing to the higher surface area, compare to conventional micron-size Akermanite (AM). Accordingly, we used the unique advantage of nanotechnology to improve novel nano akermanite particles as a potential candidate for bone tissue regeneration whether as a per implant filling powder or in combination with other biomaterials as a composite scaffold. Pure Akermanite (PAM) powders were successfully obtained via a simple sol-gel method followed by calcination at 1250 °C.

The work focused on optimization of the composite capacity to extract four fluoroquinolones (FQs) antibiotics, ciprofloxacin, enrofloxacin, danofloxacin, and difloxacin from water and improvement of composite stability towards acid and atmospheric degradation. Self-doped polyaniline nanofibers were prepared by oxidative co-polymerization of aniline with anthranilic acid. Magnetite nanopariticles were prepared by alkaline co-precipitation and coated with silica by silicate hydrolysis on magnetite nanoparticles surface at pH 6.5. The composite was formed by self-assembly by mixing self-doped polyaniline nanofibers with silica-coated magnetite nanoparticles dispersions in ethanol. The composite structure was confirmed by transmission electron microscopy (TEM). Self-doped polyaniline nanofibers and magnetite chemical structures were confirmed by FT-IR while silica coating of the magnetite was confirmed by Energy Dispersion X-ray Spectroscopy (EDS). Improved stability of the composite magnetic component was evidenced by resistance to degrade in 2N HCl solution. The adsorption capacity of self-doped polyaniline nanofibers based composite was higher than previously reported corresponding composite prepared from polyaniline nanofibers instead of self-doped polyaniline nanofibers. Adsorption-pH profile for the studied FQs on the prepared composite revealed that the best pH for adsorption was in range of 6.5 to 7. Best extraction recovery values were obtained at pH 7 using phosphate buffer. The best solvent for FQs desorption was found to be 0.1N HCl in methanol:water (8:2; v/v) mixture. 20 mL of Spiked water sample with studied FQs were preconcentrated using 4.8 mg of composite and resulting extracts were analysed by HPLC-UV method. The prepared composite represented a suitable adsorbent phase for magnetic dispersive micro-solid phase application. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluoroquinolones" title="fluoroquinolones">fluoroquinolones</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20dispersive%20micro%20extraction" title=" magnetic dispersive micro extraction"> magnetic dispersive micro extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-composite" title=" nano-composite"> nano-composite</a>, <a href="https://publications.waset.org/abstracts/search?q=self-doped%20polyaniline%20nanofibers" title=" self-doped polyaniline nanofibers"> self-doped polyaniline nanofibers</a> </p> <a href="https://publications.waset.org/abstracts/112283/magnetic-nano-composite-of-self-doped-polyaniline-nanofibers-for-magnetic-dispersive-micro-solid-phase-extraction-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112283.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">122</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">2989</span> Moisture Absorption Analysis of LLDPE-NR Nanocomposite for HV Insulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20S.%20Kamarulzaman">M.

The degradation can lead to premature breakdown and definitely will spent highly cost to replace the cable. Thus, there are many research on nano composite material get serious attention attention due to their abilities to enhance electrical performance by addition of nano filler. In this paper, water absorption of Low Linear Density Polyethyelene (LLDPE) with different amount of nano filler added is studied. This study is necessary to be conducted since most of electrical apparatus such as cable insulation are dominant used especially in high voltage application. The cable insulation are continuously exposed in uncontrolled environment may suffer degradation process. Three type of nano fillers, was used in this study are: Silicon dioxide (SiO2), Titanium dioxide (TiO2) and Monmorillonite (MMT). The percentage absorption of water was measured by weighted using high precision scales for absorption process up to 92 days. Experimental result demonstrate that SiO2 absorb less water than other filler while, the MMT has hydrophilic properties which it absorbs more water compare to another sample. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano%20composite" title="nano composite">nano composite</a>, <a href="https://publications.waset.org/abstracts/search?q=nano%20filler" title=" nano filler"> nano filler</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20absorption" title=" water absorption"> water absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophilic%20properties" title=" hydrophilic properties"> hydrophilic properties</a> </p> <a href="https://publications.waset.org/abstracts/10047/moisture-absorption-analysis-of-lldpe-nr-nanocomposite-for-hv-insulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10047.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">356</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">2988</span> Design and Synthesis of Gradient Nanocomposite Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pu%20Ying-Chih">Pu Ying-Chih</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Yin-Ju"> Yang Yin-Ju</a>, <a href="https://publications.waset.org/abstracts/search?q=Hang%20Jian-Yi"> Hang Jian-Yi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jang%20Guang-Way"> Jang Guang-Way </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organic-Inorganic hybrid materials consisting of graded distributions of inorganic nano particles in organic polymer matrices were successfully prepared by the sol-gel process.

Syahrial</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brake shoe is a component that serves to reduce speed or stop the train's speed by utilizing the friction force. Generally, the material used as a brake shoe is cast iron, where cast iron itself is a heavy, expensive, and easily worn material. Aluminum matrix composites are one of candidates for the cast iron replacement material as the basic material for brake shoe. The matrix in the composite used is Aluminum AC4B. Reinforcement used in aluminum matrix composites is nano-alumina, where the use of nano-alumina of 0.25%, 0.3%, 0.35%, 0.4%, and 0.5% volume fraction will be tested. The sample is made using the stir casting method; then, it will be tested mechanically. The use of nano-alumina as a reinforcement will increase the strength of the matrix. SEM (scanning electron microscopy) testing is used to test the distribution of reinforcing particles due to stirring. Therefore, the addition of nano-alumina will improve AC4B aluminum matrix composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aluminium%20matrix%20composites" title="aluminium matrix composites">aluminium matrix composites</a>, <a href="https://publications.waset.org/abstracts/search?q=brake%20shoe%20application" title=" brake shoe application"> brake shoe application</a>, <a href="https://publications.waset.org/abstracts/search?q=stir%20casting" title=" stir casting"> stir casting</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-alumina" title=" nano-alumina"> nano-alumina</a> </p> <a href="https://publications.waset.org/abstracts/125019/the-effect-of-volume-fraction-of-nano-alumina-strengthening-on-ac4b-composite-characteristics-through-the-stir-casting-method-as-a-material-brake-shoe" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125019.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">132</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">2986</span> High-Temperature Tribological Characterization of Nano-Sized Silicon Nitride + 5% Boron Nitride Ceramic Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Farooq%20Wani">Mohammad Farooq Wani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tribological studies on nano-sized ß-silicon nitride+5% BN were carried out in dry air at high temperatures to clarify the lack of consensus in the bibliographic data concerning the Tribological behavior of Si3N4 ceramics and effect of doped hexagonal boron nitride on coefficient of friction and wear coefficient at different loads and elevated temperatures. The composites were prepared via high energy mechanical milling and subsequent spark plasma sintering using Y2O3 and Al2O3 as sintering additives. After sintering, the average crystalline size of Si3N4 was observed to be 50 nm. Tribological tests were performed with temperature and Friction coefficients 0.16 to 1.183 and 0.54 to 0.71 were observed for Nano-sized ß-silicon nitride+5% BN composite under normal load of 10N-70 N and over high temperature range of 350 ºC-550 ºC respectively. Specific wear coefficients from 1.33x 10-4 mm3N-1m-1 to 4.42x 10-4 mm3N-1m-1 were observed for Nano-sized Si3N4 + 5% BN composite against Si3N4 ball as tribo-pair counterpart over high temperature range of 350 ºC-550 ºC while as under normal load of 10N to70N Specific wear coefficients of 6.91x 10-4 mm3N-1m-1 to 1.70x 10-4 were observed. The addition of BN to the Si3N4 composite resulted in a slight reduction of the friction coefficient and lower values of wear coefficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ceramics" title="ceramics">ceramics</a>, <a href="https://publications.waset.org/abstracts/search?q=tribology" title=" tribology"> tribology</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20and%20wear" title=" friction and wear"> friction and wear</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20lubrication" title=" solid lubrication"> solid lubrication</a> </p> <a href="https://publications.waset.org/abstracts/15590/high-temperature-tribological-characterization-of-nano-sized-silicon-nitride-5-boron-nitride-ceramic-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15590.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">377</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">2985</span> Effect of Nano Packaging Containing Ag-TiO₂ in Inactivating the Selected Bacteria Experimentally Exposed to the Chicken-Eggshell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Ahari">Hamed Ahari</a>, <a href="https://publications.waset.org/abstracts/search?q=Sepideh%20Farokhi"> Sepideh Farokhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Reza%20Abedini"> Mohamad Reza Abedini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper focuses on inactivation of the growth of the bacterial mixture, Salmonella enteritidis, Staphylococcus aureus, Bacillus cereus and Escherichia coli, experimentally subjected to the chicken eggshell by two types of nano particle-Ag, composite film and colloidal spray carried out at concentrations of 500, 1000 and 2000 ppm over 28 days. The GLM, Repeated Measurement-ANOVA procedure was used to analyze the effect of time and concentration of nano groups on inactivation of bacteria, simultaneously. The maximum reduction of the bacterial growth was respected to the group “spray 2000 ppm” for which the value of the bacteria reached the minimum (0.93±0.42) on day 7, calculated to be 0.0 on days14 and 28 and followed by the group “spray 1000 ppm”. It was obviously concluded that increasing the dilution of nano coating in spray and film created a significant decrease in the number of bacteria colonies on the eggshells but the effect of packaging in different concentrations of nanocomposite was not statistically significant in different days of the study. <p class="card-text"><strong>Keywords:</strong> <a
