Abstract In this study, we investigated the influence of O 2 , SO and NO x on branched linear polyethyleneimine (PEI) functional silica CO adsorbents (BPEI-SiO LPEI-SiO respectively). was much more likely to oxidize BPEI-SiO compared with form C=O C=N groups led a 23.0% decrease in adsorption capacity after 990 min cumulative contact 10% . contrast, lost only approximately 3.6% its capacity, al...

Osteogenic scaffolds reproducing the natural bone composition, structures, and properties have represented possible frontier of artificially orthopedic implants with great potential to revolutionize surgical strategies against bone-related diseases. However, it is difficult achieve an all-in-one formula simultaneous requirement favorable biocompatibility, flexible adhesion, high mechanical stre...

Bisphosphonates (BPs) constitute a class of drugs used for the treatment calcium- and bone-related disorders, including osteoporosis, Paget’s disease, etc. The presence anionic phosphonate groups endows them with ability to act as ligands metal ions. As result, synthesis complexes or coordination polymers various structural motifs can be accomplished. In this work, 3rd generation BP drug risedr...

Due to the good photocatalytic activity, the TiO2@CNTs thin film is highly desirable to apply to the self-cleaning glass for green intelligent building. Here, the TiO2@CNTs thin film has been successfully achieved by polymer-assisted approach of an aqueous chemical solution method. The polymer, polyethylenimine, aims to combine the Ti4+ with CNTs for film formation of TiO2@CNTs. The resultant t...

Hybrids of silver particles of 1 to 2 nm in size with highly branched amphiphilically modified polyethyleneimines adhere effectively to polar substrates providing environmentally friendly antimicrobial coatings.

Several sulphated polysaccharides have been shown to block the infection of T-cells by the human immunodeficiency virus (HIV)-l [1,2]. Dextrin-2-sulphate (D2S) is a synthetically sulphated polysaccharide which inhibits infection of human T-cell lines by a variety of HIV-1 cell-free isolates [3]. Although its mechanism of action has not been established, this compound appears to prevent HIV-1 in...
