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">2131</span> Improved Mechanical Properties and Osteogenesis in Electrospun Poly L-Lactic Ultrafine Nanofiber Scaffolds Incorporated with Graphene Oxide</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Weili%20Shao">Weili Shao</a>, <a href="https://publications.waset.org/abstracts/search?q=Qian%20Wang"> Qian Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianxin%20He"> Jianxin He</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, the applications of graphene oxide in fabricating scaffolds for bone tissue engineering have been received extensive concern.

The results indicated that the composite nanofiber scaffolds had finer fiber diameter and higher porosity as compared with pure poly l-lactic nanofibers. Furthermore, incorporation of graphene oxide into the poly l-lactic nanofibers increased protein adsorptivity, boosted the Young’s modulus and tensile strength by nearly 4.2-fold and 3.5-fold, respectively, and significantly enhanced adhesion, proliferation, and osteogenesis in mouse mesenchymal stem cells.

PU nanofibers were prepared by electrospinning and then PEDOT was coated on the plasma modified PU nanofiber surface via in-situ polymerization to form flexible PEDOT/PU composite nanofibers with conductivity. The results show PEDOT is successfully synthesized on the surface of PU nanofiber and PEDOT/PU composite nanofibers possess skin-core structure. Furthermore, the experiments indicate the optimal technological parameters of the polymerization process are as follow: The concentration of EDOT monomers is 50 mmol/L, the polymerization time is 24 h and the temperature is 25℃. The PEDOT/PU nanofibers exhibit excellent electrical conductivity ( 27.4 S/cm). In addition, flexible sensor made from conductive PEDOT/PU nanofibers shows highly sensitive response towards tensile strain and also can be used to detect finger motion.

Among these polymers, proteins from different sources have been extensively employed because of their relative abundance, film forming ability, and nutritional qualities. In this study, the biodegradable composite nanofiber films based on fish sarcoplasmic protein (FSP) were prepared via electrospinning technique. Biodegradable polycaprolactone (PCL) was blended with the FSP to obtain hybrid FSP/PCL nanofiber mats with desirable physical properties. Mixture solutions of FSP and PCL were produced at different concentrations and their density, viscosity, electrical conductivity and surface tension were measured.

By the means of dimensions, these fibers are as small as nano scale but because of having large surface area and microstructural characteristics, they provide unique mechanic, optical, magnetic, electronic and chemical properties. In terms of nanofiber production, electrospinning has been the most widely used technique in recent years. In this study, carbon nanofibers have been synthesized from solutions of Polyacrylonitrile (PAN)/ N,N-dimethylformamide (DMF) by electrospinning method. The carbon nanofibers have been stabilized by oxidation at 250 °C for 2 h in air and carbonized at 750 °C for 1 h in H2/N2. Images of carbon nanofibers have been taken with scanning electron microscopy (SEM). The images have been analyzed to study the fiber morphology and to determine the distribution of the fiber diameter using FibraQuant 1.3 software. Then polymer composites have been produced from mixture of carbon nanofibers and silicone polymer. The final polymer composites have been characterized by X-ray diffraction method and scanning electron microscopy (SEM) energy dispersive X-ray (EDX) measurements. These results have been reported and discussed. At result, homogeneous carbon nanofibers with 100-167 nm of diameter were obtained with optimized electrospinning conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title="electrospinning">electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofiber" title=" nanofiber"> nanofiber</a> </p> <a href="https://publications.waset.org/abstracts/82591/characterization-of-electrospun-carbon-nanofiber-doped-polymer-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82591.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">394</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">2122</span> Parameter Study for TPU Nanofibers Fabricated via Centrifugal Spinning </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasin%20Akg%C3%BCl">Yasin Akgül</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20Polat"> Yusuf Polat</a>, <a href="https://publications.waset.org/abstracts/search?q=Emine%20Canbay"> Emine Canbay</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20K%C4%B1l%C4%B1%C3%A7"> Ali Kılıç</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrospinning is the most common method to produce nanofibers.

Sol-gel process is required for electrospinning of silica nanofibers in which a metal alkoxide is hydrolyzed, and the viscosity is increased. In this study, silica nanofibers containing silver nanoparticles were synthesized and electrospun from a mixture of silica sol with an easy spinnable polymer (PVA) as an additive. The silica sol contains tetraethyl orthosilicate (TEOS), silver nitrate, distilled water, nitric acid, and ethanol. Nanofibers were formed through electrospinning setup. The nanofibers were calcinated to remove the solvent and additive polymer. Consequently, pure silica nanofibers were produced. FTIR analysis indicated entire removal of polyvinyl alcohol from the structure and formation of silan groups. The presence of silver, silica and oxygen was confirmed by EDX. Also, XRD patterns revealed the presence of silver nanoparticles with a mean crystal size of 18 nm. FESEM images showed that adding silver nitrate into the sol-gel, resulted in lower nanofibers diameter from 286 to 136 nm. Furthermore, the electrospun nanofibers were more resistance in acidic media than alkaline media. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=in%20situ%20synthesis%20of%20silver%20nanoparticles" title="in situ synthesis of silver nanoparticles">in situ synthesis of silver nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=silica%20nanofibers" title=" silica nanofibers"> silica nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=sol-gel" title=" sol-gel"> sol-gel</a>, <a href="https://publications.waset.org/abstracts/search?q=tetraethyl%20orthosilicate" title=" tetraethyl orthosilicate"> tetraethyl orthosilicate</a> </p> <a href="https://publications.waset.org/abstracts/82795/fabrication-and-characterization-of-glass-nanofibers-through-electrospinning-of-silica-sol-gel-along-with-in-situ-synthesis-of-ag-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82795.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">179</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">2119</span> Preparation of Silicon-Based Oxide Hollow Nanofibers Using Single-Nozzle Electrospinning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juiwen%20Liang">Juiwen Liang</a>, <a href="https://publications.waset.org/abstracts/search?q=Choliang%20Chung"> Choliang Chung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the silicon-base oxide nanofibers with hollow structure were prepared using single-nozzle electrospinning and heat treatment.

First, the composite of carboxymethyl cellulose containing different metal nanoparticles (CMC/MNPs), such as copper nanoparticles (CuNPs), iron nanoparticles (FeNPs), zinc nanoparticles (ZnNPs), cadmium nanoparticles (CdNPs) and cobalt nanoparticles (CoNPs) were synthesized, and finally, these composites were transferred to the electrospinning process. Synthesized CMC-MNPs were characterized using scanning electron microscopy (SEM) coupled with high-energy dispersive X-ray (EDX) and UV-visible spectroscopy used to confirm nanoparticle formation. The SEM images clearly showed regular flat shapes with semi-porous surfaces. All MNPs were well distributed inside the backbone of the cellulose without aggregation. The average particle diameters were 29-39 nm for ZnNPs, 29-33 nm for CdNPs, 25-33 nm for CoNPs, 23-27 nm for CuNPs and 22-26 nm for FeNPs. Surface morphology, water uptake and release of MNPs from the nanofibers in water and antimicrobial efficacy were studied. SEM images revealed that electrospun CMC-MNPs nanofibers are smooth and uniformly distributed without bead formation with average fiber diameters in the range of 300 to 450 nm. Fiber diameters were not affected by the presence of MNPs. TEM images showed that MNPs are present in/on the electrospun CMC-MNPs nanofibers. The diameter of the electrospun nanofibers containing MNPs was in the range of 300–450 nm. The MNPs were observed to be spherical in shape. The CMC-MNPs nanofibers showed good hydrophilic properties and had excellent antibacterial activity against the Gram-negative bacteria Escherichia coli and the Gram-positive bacteria Staphylococcus aureus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrospinning%20technique" title="electrospinning technique">electrospinning technique</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20nanoparticles" title=" metal nanoparticles"> metal nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=cellulosic%20nanofibers" title=" cellulosic nanofibers"> cellulosic nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=wound%20dressing" title=" wound dressing"> wound dressing</a> </p> <a href="https://publications.waset.org/abstracts/39779/antibacterial-wound-dressing-based-on-metal-nanoparticles-containing-cellulose-nanofibers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39779.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">329</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">2117</span> Electrolyte Loaded Hexagonal Boron Nitride/Polyacrylonitrile Nanofibers for Lithium Ion Battery Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umran%20Kurtan">Umran Kurtan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamide%20Aydin"> Hamide Aydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Sevim%20Unugur%20Celik"> Sevim Unugur Celik</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayhan%20Bozkurt"> Ayhan Bozkurt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work, novel hBN/polyacrylonitrile composite nanofibers were produced via electrospinning approach and loaded with the electrolyte for rechargeable lithium-ion battery applications.

The influence of hBN/PAN ratios onto the properties of the porous composite system, such as fiber diameter, porosity, and the liquid electrolyte uptake capability were systematically studied. Ionic conductivities and electrochemical characterizations were evaluated after loading electrospun hBN/PAN composite nanofiber with liquid electrolyte, i.e., 1 M lithium hexafluorophosphate (LiPF6) in ethylene carbonate (EC)/ethyl methyl carbonate (EMC) (1:1 vol). The electrolyte loaded nanofiber has a highest ionic conductivity of 10−3 S cm⁻¹ at room temperature. According to cyclic voltammetry (CV) results it exhibited a high electrochemical stability window up to 4.7 V versus Li+/Li.

Considering high safety and low cost properties of the resulting hBN/PAN fiber electrolytes, these materials can be suggested as potential separator materials for lithium-ion batteries. <p class="card-text"><strong>Keywords:</strong> <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=polyacrylonitrile" title=" polyacrylonitrile"> polyacrylonitrile</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=lithium%20ion%20battery" title=" lithium ion battery"> lithium ion battery</a> </p> <a href="https://publications.waset.org/abstracts/96557/electrolyte-loaded-hexagonal-boron-nitridepolyacrylonitrile-nanofibers-for-lithium-ion-battery-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96557.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">148</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">2116</span> UV Resistibility of a Carbon Nanofiber Reinforced Polymer Composite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Evcin">A.

Nanocarbon materials, such as carbon nanotubes (CNTs), carbon nanofibers (CNFs) and graphene, have been considered promising alternatives to shielding materials because of their excellent electrical conductivities, very high surface areas and low densities. In the present work, carbon nanofibers have been synthesized from solutions of Polyacrylonitrile (PAN)/ N,N-dimethylformamide (DMF) by electrospinning method. The carbon nanofibers have been stabilized by oxidation at 250 °C for 2 h in air and carbonized at 750 °C for 1 h in H2/N2. We present the fabrication and characterization of transparent and ultraviolet (UV) shielding CNF/polymer composites. The content of CNF filler has been varied from 0.2% to 0.6 % by weight. UV Spectroscopy has been performed to study the effect of composition on the transmittance of polymer composites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title="electrospinning">electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanofiber" title=" carbon nanofiber"> carbon nanofiber</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofiber" title=" nanofiber"> nanofiber</a>, <a href="https://publications.waset.org/abstracts/search?q=ultraviolet%20radiation" title=" ultraviolet radiation"> ultraviolet radiation</a> </p> <a href="https://publications.waset.org/abstracts/83495/uv-resistibility-of-a-carbon-nanofiber-reinforced-polymer-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83495.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">225</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">2115</span> Electrospinning in situ Synthesis of Graphene-Doped Copper Indium Disulfide Composite Nanofibers for Efficient Counter Electrode in Dye-Sensitized Solar Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lidan%20Wang">Lidan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuyuan%20Zhao"> Shuyuan Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianxin%20He"> Jianxin He</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, graphene-doped copper indium disulfide (rGO+CuInS2) composite nanofibers were fabricated via electrospinning, in situ synthesis, and carbonization, using polyvinyl pyrrolidone (PVP), copper dichloride (CuCl2), indium trichloride (InCl3), thiourea (C2H5NS) and graphene oxide nanosheets (Go) as the precursor solution for electrospinning. The average diameter of rGO+CuInS2 nanofibers were about 100 nm, and graphene nanosheets anchored with chalcopyrite CuInS2 nanocrystals 8-15 nm in diameter were overlapped and embedded, aligning along the fiber axial direction. The DSSC with a rGO+CuInS2 counter electrode exhibits a power conversion efficiency of 5.93%; better than the corresponding values for a DSSC with a CuInS2 counter electrode, and comparable to that of a reference DSSC with a Pt counter electrode. The excellent photoelectric performance of the rGO+CuInS2 counter electrode was attributed to its high specific surface area, which facilitated permeation of the liquid electrolytes, promoted electron and ion transfer and provided numerous catalytically active sites for the oxidation reaction of the electrolytic (I- /I3-). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dye-sensitized%20solar%20cells" title="dye-sensitized solar cells">dye-sensitized solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=counter%20electrode" title=" counter electrode"> counter electrode</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene" title=" graphene"> graphene</a> </p> <a href="https://publications.waset.org/abstracts/68098/electrospinning-in-situ-synthesis-of-graphene-doped-copper-indium-disulfide-composite-nanofibers-for-efficient-counter-electrode-in-dye-sensitized-solar-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68098.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">457</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">2114</span> Effect of Lemongrass Oil Containing Polycaprolactone Nanofibers on Biofilm Formation of Proteus mirabilis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gulcan%20Sahal">Gulcan Sahal</a>, <a href="https://publications.waset.org/abstracts/search?q=Behzad%20Nasseri"> Behzad Nasseri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Akbar%20Ebrahimi"> Ali Akbar Ebrahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Isil%20Seyis%20Bilkay"> Isil Seyis Bilkay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Proteus mirabilis strains which are natural colonizers of healthy individuals’ gastrointestinal tract are also known as common causes of catheter-associated urinary tract infections. Nowadays, as a result of an increased resistance to various antimicrobial drugs, there has been a growing interest in natural products. Therefore, the aim of this study is to investigate biofilm formation of P. mirabilis strains on lemongrass oil containing polycaprolactone nanofibers. Polycaprolactone nanofibers with different lemongrass oil concentrations were successfully prepared by electrospinning and biofilm formation of P. mirabilis on these nanofibers were determined by ‘Crystal Violet Staining Assay’. According to our results, polycaprolactone nanofibers with some lemongrass oil concentrations, decreased biofilm formation of P. mirabilis and this effect increased in parallel with the increase in lemongrass oil concentration. Our results indicate that, polycaprolactone nanofibers with some concentrations of lemongrass oil may provide a treatment against catheter-associated urinary tract infections by means of causing an inhibition on biofilm formation of P. mirabilis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-biofilm" title="anti-biofilm">anti-biofilm</a>, <a href="https://publications.waset.org/abstracts/search?q=biofilm%20formation" title=" biofilm formation"> biofilm formation</a>, <a href="https://publications.waset.org/abstracts/search?q=essential%20oils" title=" essential oils"> essential oils</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title=" nanofibers"> nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=proteus%20mirabilis" title=" proteus mirabilis"> proteus mirabilis</a> </p> <a href="https://publications.waset.org/abstracts/55250/effect-of-lemongrass-oil-containing-polycaprolactone-nanofibers-on-biofilm-formation-of-proteus-mirabilis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55250.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">412</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">2113</span> Advantages of a New Manufacturing Facility for the Production of Nanofiber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20Knizek">R.

Gelatin, one of the most available naturally derived hydrogels of amino acids, is a popular choice for food additives, cosmetic ingredients, biomedical implants, or dressing of its non-toxic and biodegradable nature. Nevertheless, synthetic hydrogel polyvinyl alcohol has long been used as a thickening agent for adhesion purposes. Many biomedical devices are also containing polyvinyl-alcohol as a major content, such as eye drops and contact lenses. To discover appropriate compositions of gelatin and polyvinyl-alcohol for electrospun nanofibers, polymer solutions of different volumetric ratios between gelatin and polyvinyl alcohol were prepared for electrospinning. The viscosity, surface tension, pH value, and electrical conductance of polymer solutions were measured. On the nanofibers, the vibrational modes of molecular structures in nanofibers were investigated by Fourier-transform infrared spectroscopy. The morphologies and surface chemical elements of fibers were examined by the scanning electron microscope and the energy-dispersive X-ray spectroscopy. The hydrophilicity of nanofiberswas evaluated by the water contact angles on the surface of the fibers. To further test the biotoxicity of nanofibers, an in-vitro 3T3 fibroblasts culture further tested the biotoxicity of the electrospun nanofibers. Throughstatistical analyses of the experimental data, it is found that the polyvinyl-alcohol rich composition (the volumetric ratio of gelatin/polyvinyl-alcohol < 1) would be a preferable choice for the formation of nanofibers by the current setup of electrospinning. These electrospun nanofibers tend to be hydrophilic with no biotoxicity threat to the 3T3 fibroblasts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gelatin" title="gelatin">gelatin</a>, <a href="https://publications.waset.org/abstracts/search?q=polyvinyl-alcohol" title=" polyvinyl-alcohol"> polyvinyl-alcohol</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title=" nanofibers"> nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=spin%20coating" title=" spin coating"> spin coating</a> </p> <a href="https://publications.waset.org/abstracts/151985/the-compositional-effects-on-electrospinning-of-gelatin-and-polyvinyl-alcohol-mixed-nanofibers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151985.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">85</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">2111</span> Preparation and Characterisation of Electrospun Extracted β-Chitosan/Poly(Vinyl Alcohol) Blend Nanofibers for Tissue Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Roshan%20Ara%20Begum">E.

Therefore, this study focused on production of β-chitosan(β-Cts) and Poly(vinyl alcohol)(PVA) blend nanofibrous scaffold by electrospinning. β-Cts was extracted from the squid pen waste of locally available squid variety Loligo duvauceli (Indian Squid). To the best of our knowledge, there are no reports on nanofibers preparation from the extracted β-Cts. Both the β-Cts and PVA polymers were mixed in two different proportions (30:70 and 40:60 respectively. The electrospun nanofibrous scaffolds were characterized by SEM, swelling property, in vitro enzymatic degradation, and hemo, biocompatibility properties. β-Cts/PVA nanofibers scaffolds had an average fiber diameter of 120 to 550nm.Among the two different β-Cts/PVA blends nanofibers the β-Cts/PVA (40:60) blend fibers demonstrated favourable tissue engineering properties. The β-Cts/PVA (40:60) blend nanofibers exhibited a swelling ratio of 36 ± 2.5% with mass loss percentage of 20 ± 2.71% after 4 weeks of degradation. It has exhibited good hemocompatible properties. HEK-293(Human Embryonic Kidney) cells lines were able to adhere and proliferate well in the β-Cts/PVA blends nanofibers. All these results indicated that electrospun β-Cts/PVA blends nanofibers are a suitable scaffold to be used for tissue engineering purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%CE%B2-chitosan" title="β-chitosan">β-chitosan</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibers" title=" nanofibers"> nanofibers</a>, <a href="https://publications.waset.org/abstracts/search?q=poly%28vinyl%20alcohol%29%20%28PVA%29" title=" poly(vinyl alcohol) (PVA)"> poly(vinyl alcohol) (PVA)</a> </p> <a href="https://publications.waset.org/abstracts/85353/preparation-and-characterisation-of-electrospun-extracted-v-chitosanpolyvinyl-alcohol-blend-nanofibers-for-tissue-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85353.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">235</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">2110</span> Preparation of Bead-On-String Alginate/Soy Protein Isolated Nanofibers via Water-Based Electrospinning and Its Application for Drug Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Patcharakamon%20Nooeaid">Patcharakamon Nooeaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Piyachat%20Chuysrinuan"> Piyachat Chuysrinuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrospun natural polymers-based nanofibers are one of the most interesting materials used in tissue engineering and drug delivery applications. Bead-on-string nanofibers have gained considerable interest for sustained drug release. Vancomycin was used as the model drug and sodium alginate (SA)/soy protein isolated (SPI) as the polymer blend to fabricate the bead-on-string nanofibers by aqueous-based electrospinning. The bead-on-string SA/SPI nanofibers were successfully fabricated by the addition of poly(ethylene oxide) (PEO) as a co-blending polymer. SA-PEO with mass ratio of 70/30 showed the best spinnability with continuous nanofibers without the occurrence of beads. Bead structure formed with the addition of SPI and bead number increased with increasing SPI content. The electrospinning of 80/20 SA-PEO/SPI was obtained as a great promising bead-on-string nanofibers for drug loading, while the solution of 50/50 was not able to obtain continuous fibers. In vitro release tests showed that a more sustainable release profile up to 14 days with less initial burst release on day 1 could be obtained from the bead-on-string fibers than from smooth fibers with uniform diameter. In addition, vancomycin-loaded beaded fibers inhibited the growth of Staphylococcus aureus (S. aureus) bacteria. Therefore, the SA-PEO/SPI nanofibers showed the potential to be used as biomaterials for tissue engineering and drug delivery. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bead-on-string%20fibers" title="bead-on-string fibers">bead-on-string fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20delivery" title=" drug delivery"> drug delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20engineering" title=" tissue engineering "> tissue engineering </a> </p> <a href="https://publications.waset.org/abstracts/49420/preparation-of-bead-on-string-alginatesoy-protein-isolated-nanofibers-via-water-based-electrospinning-and-its-application-for-drug-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49420.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">334</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">2109</span> Fabrication and Characterization of Gelatin Nanofibers Dissolved in Concentrated Acetic Acid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kooshina%20Koosha">Kooshina Koosha</a>, <a href="https://publications.waset.org/abstracts/search?q=Sima%20Habibi"> Sima Habibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Azam%20Talebian"> Azam Talebian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrospinning is a simple, versatile and widely accepted technique to produce ultra-fine fibers ranging from nanometer to micron.

Various water filtration techniques have been employed till now for purification and removal of hazardous metals from water. Among all the existing methods, nanofibres have emerged as a viable alternative for effective heavy metal removal in recent years because of their unique qualities, such as large surface area, interconnected porous structure, and customizable surface chemistry. Among the numerous manufacturing techniques, solution blow spinning has gained popularity as a versatile process for producing nanofibers with customized properties. This paper seeks to offer a complete overview of the use of nanofibers for heavy metal filtration, particularly those produced using solution blow spinning.

Jo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Poly vinyl acetate (PVA)-based titania (TiO2)–carbon nanotube composite nanofibers (PVA-TCCNs) with various PVA-to-solvent ratios and PVA-based TiO2 composite nanofibers (PVA-TN) were synthesized using an electrospinning process, followed by thermal treatment. The photocatalytic activities of these nanofibers in the degradation of airborne monocyclic aromatics under visible-light irradiation were examined. This study focuses on the application of these photocatalysts to the degradation of the target compounds at sub-part-per-million indoor air concentrations. The characteristics of the photocatalysts were examined using scanning electron microscopy, X-ray diffraction, ultraviolet-visible spectroscopy, and Fourier-transform infrared spectroscopy. For all the target compounds, the PVA-TCCNs showed photocatalytic degradation efficiencies superior to those of the reference PVA-TN. Specifically, the average photocatalytic degradation efficiencies for benzene, toluene, ethyl benzene, and o-xylene (BTEX) obtained using the PVA-TCCNs with a PVA-to-solvent ratio of 0.3 (PVA-TCCN-0.3) were 11%, 59%, 89%, and 92%, respectively, whereas those observed using PVA-TNs were 5%, 9%, 28%, and 32%, respectively. PVA-TCCN-0.3 displayed the highest photocatalytic degradation efficiency for BTEX, suggesting the presence of an optimal PVA-to-solvent ratio for the synthesis of PVA-TCCNs. The average photocatalytic efficiencies for BTEX decreased from 11% to 4%, 59% to 18%, 89% to 37%, and 92% to 53%, respectively, when the flow rate was increased from 1.0 to 4.0 L min1. In addition, the average photocatalytic efficiencies for BTEX increased 11% to ~0%, 59% to 3%, 89% to 7%, and 92% to 13% , respectively, when the input concentration increased from 0.1 to 1.0 ppm. The prepared PVA-TCCNs were effective for the purification of airborne aromatics at indoor concentration levels, particularly when the operating conditions were optimized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mixing%20ratio" title="mixing ratio">mixing ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofiber" title=" nanofiber"> nanofiber</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer" title=" polymer"> polymer</a>, <a href="https://publications.waset.org/abstracts/search?q=reference%20photocatalyst" title=" reference photocatalyst"> reference photocatalyst</a> </p> <a href="https://publications.waset.org/abstracts/19294/control-of-airborne-aromatic-hydrocarbons-over-tio2-carbon-nanotube-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19294.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">2106</span> Optimization of Parameters for Electrospinning of Pan Nanofibers by Taguchi Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gamze%20Karanfil%20Celep">Gamze Karanfil Celep</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevser%20Dincer"> Kevser Dincer </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of polymer concentration and electrospinning process parameters on the average diameters of electrospun polyacrylonitrile (PAN) nanofibers were experimentally investigated. Besides, mechanical and thermal properties of PAN nanofibers were examined by tensile test and thermogravimetric analysis (TGA), respectively. For this purpose, the polymer concentration, solution feed rate, supply voltage and tip-to-collector distance were determined as the control factors. To succeed these aims, Taguchi’s L16 orthogonal design (4 parameters, 4 level) was employed for the experimental design. Optimal electrospinning conditions were defined using the signal-to-noise (S/N) ratio that was calculated from diameters of the electrospun PAN nanofibers according to "the-smaller-the-better" approachment. In addition, analysis of variance (ANOVA) was evaluated to conclude the statistical significance of the process parameters. The smallest diameter of PAN nanofibers was observed. According to the S/N ratio response results, the most effective parameter on finding out of nanofiber diameter was determined. Finally, the Taguchi design of experiments method has been found to be an effective method to statistically optimize the critical electrospinning parameters used in nanofiber production. After determining the optimum process parameters of nanofiber production, electrical conductivity and fuel cell performance of electrospun PAN nanofibers on the carbon papers will be evaluated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanofiber" title="nanofiber">nanofiber</a>, <a href="https://publications.waset.org/abstracts/search?q=electrospinning" title=" electrospinning"> electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=polyacrylonitrile" title=" polyacrylonitrile"> polyacrylonitrile</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a> </p> <a href="https://publications.waset.org/abstracts/59230/optimization-of-parameters-for-electrospinning-of-pan-nanofibers-by-taguchi-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59230.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">206</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">2105</span> Culture of Primary Cortical Neurons on Hydrophobic Nanofibers Induces the Formation of Organoid-Like Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nick%20Weir">Nick Weir</a>, <a href="https://publications.waset.org/abstracts/search?q=Robert%20Stevens"> Robert Stevens</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Hargreaves"> Alan Hargreaves</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20McGinnity"> Martin McGinnity</a>, <a href="https://publications.waset.org/abstracts/search?q=Chris%20Tinsley"> Chris Tinsley</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrophobic materials have previously demonstrated the ability to elevate cell-cell interactions and promote the formation of neural networks whilst aligned nanofibers demonstrate the ability to induce extensive neurite outgrowth in an aligned manner. Hydrophobic materials typically elicit an immune response upon implantation and thus materials used for implantation are typically hydrophilic. Poly-L-lactic acid (PLLA) is a hydrophobic, non-immunogenic, FDA approved material that can be electrospun to form aligned nanofibers. Primary rat cortical neurons cultured for 10 days on aligned PLLA nanofibers formed 3D cell clusters, approximately 800 microns in diameter. Neurites that extended from these clusters were highly aligned due to the alignment of the nanofibers they were cultured upon and fasciculation was also evident. Plasma treatment of the PLLA nanofibers prior to seeding of cells significantly reduced the hydrophobicity and abolished the cluster formation and neurite fasciculation, whilst reducing the extent and directionality of neurite outgrowth; it is proposed that hydrophobicity induces the changes to cellular behaviors. Aligned PLLA nanofibers induced the formation of a structure that mimics the grey-white matter compartmentalization that is observed in vivo and thus represents a step forward in generating organoids or biomaterial-based implants. Upon implantation into the brain, the biomaterial architectures described here may provide a useful platform for both brain repair and brain remodeling initiatives. <p
