Nano- and micro- fibers of conjugated polymer semiconductors are particularly interesting both for applications and for fundamental research. They allow an investigation into how electronic properties are influenced by size confinement and chain orientation within microstructures that are not readily accessible within thin films. Moreover, they open the way to many applications in organic elect...

The technique to fabricate nanofibrous mat by electro-spinning has been known for a long time. But the attempts to use the electospun nanofiber mats, also known as electro-spun nanofiber membranes (ENMs), for filtration purposes began only recently. Among many membrane filtration processes, air cleaning by the removal of dust particles has already been commercialized and the product has been in...

metal spinning as a kind of manufacturing process has capability to shape hollow components. in present work shear spinning process is used to formplates into conical shapes. moreover, the aim of this research is to demonstrate the impact of the process parameters (i.e. feeding rate and spindle speed) on wall thickness. this approachwas done by experimental and finite elements method. the resul...

used pet bottles disposal is an unsolved environmental problem, and there are many efforts for finding an applicable solution for it. many researches have showed that the degradation rate of the polymers increase with the smaller size of fibers. this work was carried out to convert used pet bottles into nanofibers by melt-electrospinning method. uncolored, washed and chipped pet bottles and the...

Lead zirconate titanate (PZT)-based ferroelectric ceramic materials are piezoelectric of commercial importance. Strontium (SZT) perovskite also have a wide application area. PZ and SZT starting solutions can be prepared using variety suitable methods. Among these methods, the sol-gel process has attracted special attention due to low temperature requirement, homogeneity ability obtain appropria...

Abstract In general, the electro-spinning of lignin requires it to be functionalised and/or blended with synthetic or natural polymers. This paper reports on use solvent fractionated lignin-lignin blend electro-spin BioChoice softwood Kraft lignin. The consisted acetone-soluble and ethanol-soluble in a binary acetone DMSO. Solvent fractionation was used purify where ash content reduced soluble ...

This investigation is aimed at analysing linear instability of an initial stable jet through the air-sealed electro-centrifugal spinning process which significant in creating nanofibers. Utilising perturbation theory to diminish governing equations, into a 1-D mode with option solving acquired non-linear differential equations. Hence, trajectory power-law fluid during power has been determined....
