The performance of an optimized tree-type cylindrical-shaped nanoporous fltering membrane proposed in the former study is analytically investigated for varying operational parameter values. Across the membrane thickness, this membrane has two-leveled tree-structured pores including one trunk pore and the multiple branch pores. The physical properties of the surfaces of ...

Introduction: Alzheimer’s disease is a progressive neurodegenerative disorder, characterized by impairment of memory and changes in behavior and personality. Recent evidence suggests that mitochondrial channels play important roles in memory disorders. Accordingly, the biophysical properties of a single potassium channel were investigated in the brain mitochondrial inner membrane of rat with...

• Bending pressure is taken into account by adding a new term in the Rayleigh–Plessetequation. Evolution of bubbles with shells obtained Sundman’s time. Closed-form solutions are through method Weierstrass elliptic equation. We present an analysis extended Rayleigh–Plesset (RP) equation for three dimensional cell microorganisms such as bacteria or viruses some liquid, where membrane envelope (c...

Hydrophobicity properties of graphite and green synthesized graphene (gsG) from exfoliated graphite/GO towards polymer membrane characteristic and properties at different weight percentage concentrations (1, 2, 3, 4 and 5 wt. %) were investigated. PSf/graphite and PSf/gsG membranes were characterized in term of hydrophobicity, surface bonding, surface roughness and porosity. FTIR peaks revealed...

Background and Objective: Human amniotic membrane, which is the innermost layer of placenta, contains beta defensins and elafin, which both have antibacterial properties. These antibacterial activities depend on the conditions and environmental factors. The purpose of this study was to evaluate the effect of environmental factors on human amniotic membrane antibacterial properties against Klebs...
