Polyvinyl alcohol nanofibrous membrane by high-curvature solid-needle electrospinning: Numerical simulation and experimental verification

Fabrication of Polyvinyl Alcohol/Kefiran Nanofibers Membrane Using Electrospinning

The Poly (vinyl alcohol)/Kefirane nanofiber membrane was successfully fabricated for the firsttime using electrospinning of the polyvinyl alcohol (PVA) and Kefirane blend solution. Scanningelectron microscope (SEM), attenuated total reflectance Fourier transform infrared (ATRFT-IR), and differential scanning calorimetry (DSC) were used to characterize the electrospunPoly (vinyl alcohol)/Kefiran...

Studies on the use of recombinant spider silk protein/polyvinyl alcohol electrospinning membrane as wound dressing

A series of wound membranes of polyvinyl alcohol and recombinant spider silk protein (pNSR16) was prepared by electrospinning. The membrane was analyzed by scanning electron microscopy, atomic force microscopy, and Fourier transform infrared spectroscopy. The result showed that the three factors that affected average fiber diameter from high to low were, voltage, flow speed, and solidification ...

EFFECT OF OPERATING CONDITIONS ON THE DEHYDRATION OF TOLUENE BY PERVAPORATION USING A POLYVINYL ALCOHOL MEMBRANE

The effects of operating parameters such as feed temperature and permeate-side pressure on the performance of a commercial PVA membrane in the dehydration of toluene by a pervaporation (PV) membrane system is studied in the present work. The results obtained indicate that increasing temperature in the range of 40 to 70 °C and reducing permeate pressure in the range of 1 to 10 mmHg increase memb...

Coupled numerical simulation of hot stamping process and experimental verification

Hot stamping process is a high non-linear process showing the effect on thermal, mechanical and metallurgical phenomena as they relate to each other. In order to carry out this coupled numerical simulation, fundamental thermal properties such as interfacial heat transfer coefficient and convection heat transfer coefficient as well as crucial mechanics properties were first investigated. Hot sta...
