The novel oriented electrospun nanofiber membrane composed of MOFs and SPPESK has been synthesized for proton exchange membrane fuel cell operating at high temperature and anhydrous conditions. It is clear that the oriented nanofiber membrane displays the higher proton conductivity than that of the disordered nanofiber membrane or the membrane prepared by conventional solvent-casting method (wi...

Electrospinning is a very simple and versatile process by which polymer nanofibers with diameters ranging from a few nanometers to several micrometers (usually between 50 and 500 nm) can be produced using an electrostatically driven jet of polymer solution (or polymer melt). Significant progress has been made in this process throughout the past few years and the resultant nanostructures have be...

Objective(S): Electrospinning of chitosan/polyethylene oxide (CS/PEO) nanofibers with the addition of cefazolin to create nanofibers with antimicrobial properties were examined. Methods: Polymeric nanofibers including CS/PEO and CS/PEO /cefazolin, were produced by electrospinning method. The range of nanofiber was 60-100 nm in diameter and measured with I...

polypyrrole (ppy) nanofibers have been fabricated on glassy carbon electrode (gce) usingelectrochemical technique. electropolymerization of pyrrole (py) for the fabrication of ppy nanofiberswas occurred on gce by applying a fixed potential of about 0.85 v for 120 sec in a mild basic solutioncontaining sodium carbonate and sodium perchlorate. in the mild basic media, the monomer, py, isoxidized ...

We describe recent experiments aimed at using carbon nanofibers for biosensing applications. Vertically aligned carbon nanofibers are grown on molybdenum electrodes to provide electrical contact to the nanofibers. Upon exposure to electrolyte solutions, we find that short nanofibers of <1 Am length can be wet and dried without significant mechanical disruption. However, longer fibers are prone ...

Nanoscale wavelength-converted optical components are promising components for communication and optical information processing in integrated photonic system. In this work, we report a facile strategy for realizing continuously tunable wavelength-converted wave-guiding in dye-doped nanofibers. The nanofibers with diameters of 200-800 nm have an absorption coefficient of about 80 cm(-1) and a se...

Electrospun nanofibers composed of polymers have been extensively researched because of their scientific and technical applications. Commercially available polyhydroxybutyrate (PHB) and polyhydroxybutyrate-co-valerate (PHB-HV) copolymers are good choices for such nanofibers. We used a highly integrated method, by adjusting the properties of the spinning solutions, where the cyanophyte Arthrospi...

Compared to the nerve guidance conduits (NGCs) constructed from a single layer of aligned nanofibers, bilayer NGCs with random and aligned nanofibers in the outer and inner layers are more robust and tear-resistant during surgical procedures thanks to an isotropic mechanical property provided by the random nanofibers. However, it remains unclear whether the random nanofibers will interfere with...

CH3NH3PbI3 perovskite nanofibers were synthesized by versatile electrospinning techniques. The synthetic CH3NH3PbI3 nanofibers were characterized by X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, and photoluminescence. As counter electrodes, the synthesized nanofibers increased the performance of the dye-sensitized solar cells from 1.58 to 2.09%. This improvement w...
