Activated carbon paper-based materials were prepared from softwood pulp, activated powder, and polyester fiber through wet forming process. Then polyethyleneimine was loaded on the using physical impregnation method to fabricate green, low cost, degradable PEI/activated composite adsorbent (PPCA) for removal of Cr(VI) drinking water. The surface characteristics analyzed by SEM, EDX, BET, FT-IR,...
Removal of gas bubbles from the electrode surface is practically important to maintain activity electrochemical evolution reactions. Conventionally, most studies have focused on development electrocatalysts and paid less attention bubble removal issues. Recently, it has been reported that attached can be readily eliminated by imparting extremely gas-repellent properties (so-called superaerophob...
Efficient high-throughput expression of genes in mammalian cells can facilitate large-scale functional genomic studies. Towards this aim, we developed a simple yet powerful method to deliver genes into cells by cationic polymers on the surface of substrates. Transfection can be achieved by directly contacting nucleic acid-cell mixtures with the cationic substrates, e.g. polyethylenimine/collage...
