Membranes have been developed by coating a blend of chitosan (CS) and polyethylene glycol (PEG) of different molecular weights (4000, 10,000 and 20,000) on cotton fabric followed by freeze drying. The influence of PEG molecular weight on the physical characteristics of the membranes has been investigated. The scanning electron microscopy of the coated fabric reveals porous structure. The porosi...

A unique strategy for scavenging free radicals in situ on exposure to gamma irradiation in polyethylene (PE) nanocomposites is presented. Blends of ultra-high molecular weight PE and linear low-density PE (PEB) and their nanocomposites with graphene (GPEB) were prepared by melt mixing to develop materials for biomedical implants. The effect of gamma irradiation on the microstructure and mechani...

Myrrh has long been used for its circulatory, disinfectant, analgesic, antirheumatic, antidiabetic, and schistosomicidal properties. Myrrh essential oil (MEO) was extracted from the oleo-gum resin of Commiphora molmol and formulated into emulsions and suppositories to mask/avoid its bitter taste. Three oil-in-water emulsions (E1-E3) were formulated and taste was evaluated by 10 volunteers. Part...

Polyethylene is amongst the most used polymers, finding a plethora of applications in our lives owing to its high impact resistance, non-corrosive nature, light weight, cost effectiveness, and easy processing into various shapes from different sizes. Despite these outstanding features, commodity polymer has been underexplored field organic electronics. This work focuses on development new blend...

Abstract In Polyethylene terephthalate (PET) processing the raw materials are purified terephthalic acid (PTA), moderately (MTA), monoehalene glycol (MEG). The of PTA is very difficult and costly. For reducing percent we using different percentages MTA blend in PET processing. affected properties polyester melt spinning process. such as elongation, tenacity, molecular chain length, b-color IV, ...

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...

An analysis model for the transient viscoelastic flow in film blowing process was newly developed based on Galerkin finite element method and incorporating cooling crystallization behaviors. Assuming that physical quantities such as temperature stress are constant thickness direction, approximated to be one dimensional axisymmetric coordinate system, Lagrangian analysis, which involves remeshin...
