The performance of nanoporous hydrogel microplugs with varying surface charge density is described in concentrating charged analytes electrokinetically in a microfluidic device. A neutral hydrogel plug with a mean pore size smaller than the size of charged analytes acts as a simple size-exclusion membrane. The presence of fixed charges on the backbone of a nanoporous hydrogel creates ion-permse...

Fractional excretion of protein may be a useful predictor of decline of renal function in pan-chronic kidney diseases Sir, We agreed with the article of McQuarrie article 'Fractional excretions of albumin and IgG are the best predictors of progression in primary glomerulonephritis'. But we were curious about the glomerular filtration rate (GFR) of high-and low-risk group patients separated by f...

Separation membranes, which have the possibility to develop energy-saving and compact processes, are expected be applied in field of CO2 separation capture attracting considerable interest from both industries academia. The purpose this review is provide an overview recent advances organic inorganic materials for high-performance membranes viewpoint molecular design engineering perspective. inc...

Since the specific energy consumption (SEC) required for reverse osmosis (RO) desalination has been steeply reduced over past few decades, there is an increasing demand high-selectivity membranes. However, it still hard to find research papers empirically dealing with salt rejection of RO membranes and addressing SEC change possibly occurring while rejection. Herein, we examined feasibility pro...
