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...

Nanocomposites films of (polymer blend-ceramics) were prepared from (PVA-PAA) blend and (PVA-PAA) blend doped with niobium carbide nanoparticles for humidity sensors have low cost, easy fabrication, high sensitivity, lightweight and high corrosion resistance. The structural, electrical and optical properties of (PVA-PAA-NbC) nanocomposites have been studied. The D.C electrical properties of (PV...

Through sequential electrospinning, a sandwich Janus membrane (PU-(CA/PU)-CA) was constructed with hydrophobic polyurethane (PU) nanofiber as the top layer, cellulose acetate/polyurethane (CA/PU) blend intermediate transition layer and hydrophilic acetate (CA) bottom layer. The effects of structure, composition thickness on mechanical properties, permeability separation ability PU-(CA/PU)-CA we...

The application of membrane proteins in biotechnology requires robust, durable reconstitution systems that enhance their stability and support their functionality in a range of working environments. Vesicular architectures are highly desirable to provide the compartmentalisation to utilise the functional transmembrane transport and signalling properties of membrane proteins. Proteoliposomes pro...

A hierarchical procedure bridging the gap between atomistic and mesoscopic simulations for materials design is presented. A dissipative particle dynamics (DPD) is adopted for a mesoscopic simulation technique. In this method, a molecular structure is represented using a coarse-grained model, connecting soft spherical particles that correspond to a group of several atoms. The interaction paramet...

In this work, a mathematical model is established to describe the removal of CO2 from gaseous mixtures including CH4 and CO2 in a polypropylene hollow fiber membrane contactor in the presence of conventional absorbents such as monoethanolamine (MEA), methyldiethanolamine (MDEA), and a blend of them. Modeling was performed in axial and radial directions under the fully-wet condition for counterc...

in this study, the possibility of producing wood-plastic panels was studied using two different blending methods including melt blend and dry blend. wood-plastic panels were made from recycled high density polyethylene (as resin) and mdf waste (as natural fiber) at 60, 70 and 80% by weight filler loading. nominal density and dimensions of the panels were 1g/cm3 and 35×35×1 cm, respectively. the...
