Pervaporation is a membrane process that offers high separation performance and has an important potential for the treatment of saline water sources. In this study, poly(vinyl alcohol) (PVA) PVA-SiO2 nanocomposite membranes were prepared by solution-casting method, pervaporative desalination studies carried out synthetic seawater (35 g L-1) at 30, 40 50?C. Effects temperatures incorporation SiO...

Silicon dioxide films are extensively used in nano and micro-electromechanical systems. Here we studied the influence of an external electric field on the mechanical properties of a SiO2 film by using nanoindentation technique of atomic force microscopy (AFM) and friction force microscopy (FFM). A giant augmentation of the relative elastic modulus was observed by increasing the localized electr...
