© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim 6023 wileyonlinelibrary.com Our work is inspired by passive transport across cell membranes, which offer an intriguing example of regulating membrane permeability based on transmembrane hydrophilic/hydrophobic interactions. [ 10 ] The cell membrane has a lipid bilayer structure consisting of hydrophilic phosphate outer layers and hydrophobic hyd...

the produced liquid water in cathode catalyst layer (ccl) has significant effect on the operation of proton exchange membrane fuel cell (pemfc). to investigate this effect, the transport of oxygen in ccl in the presence of immiscible liquid water is studied applying a two-dimensional pore scale model. the ccl was reconstructed as an agglomerated system. to explore the wettability effects, diffe...

      Losartan potassium is a well known orally active non-peptide angiotensin II receptor antagonist. Losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin II by selectively blocking the binding of angiotensin II to AT1 receptors. The drug is reported to promote the decrease in ventricular hypertrophy, salt ...

The adsorption and assembly of B18 peptide on various solid surfaces were studied by reflectometry techniques and atomic force microscopy. B18 is the minimal membrane binding and fusogenic motif of the sea urchin protein bindin, which mediates the fertilization process. Silicon substrates were modified to obtain hydrophilic charged surfaces (oxide layer and polyelectrolyte multilayers) and hydr...

The adsorption of a collagen fragment on both a hydrophobic, hydrogen-terminated and a hydrophilic, natively oxidised Si surface is investigated using all-atom molecular dynamics. While favourable direct protein-surface interactions via localised contact points characterise adhesion to the hydrophilic surface, evenly spread surface/molecule contacts and stabilisation of the helical structure oc...
