Abstract(#br)Sorption behaviors were investigated for ethanol/water mixtures in polydimethylsiloxane (PDMS) films at 298\u003cce:hsp sp=\"0.25\"/\u003eK in this study. The classic UNIversal QUAsi Chemical (UNIQUAC) model and UNIQUAC-HB theory (the UNIQUAC model accounting for the hydrogen bonding effect) were employed to predict the individual sorption levels from various ethanol/water mixtures.

Abstract(#br)The adhesion of bacteria and subsequent formation of biofilm on the surface of implants greatly affect the long-term use of the implants. The low molar mass gentamicin (GS) cations could hardly be directly incorporated into the multilayer films through alternately deposition with a polyanion. Herein, we have designed and constructed a (poly(acrylic acid)/(polyvinylpyrrolidone/chitosan)) n ((PAA/(PVP/CHI)) n ) multilayer films through layer-by-layer self-assembly method.

Abstract(#br)Recently much endeavor has been devoted to improving pervaporation performances of polydimethylsiloxane (PDMS) membranes for organic aqueous solutions by doping hydrophobic porous particles. However, the strategy generally promotes water permeation as well, which is contrary to the separation purpose but has not caused researchers' attention.
