Research performance of secondary ABS plastic modified with an organosilicon compound used in automobile and mechanical engineering

The article presents a substantiation of the relevance of the use of automobile and mechanical engineering products of secondary polymer materials. The process of modification of secondary ABS plastic with an organosilicon compound vinyltris (2-methoxy-ethoxy) silane is considered, and methods for determining the physical and mechanical parameters of secondary modified polymeric materials are described and the results of their mechanical tests are presented.

The pyrolysis behaviors of phosphorus-containing organosilicon compound modified ammonium polyphosphate with different phosphorus-containing groups, and their different flame-retardant mechanisms in polyurethane foam

The centralized release of nonflammable gas and quick formation of crosslinked structure increase the flame retardant properties of polyurethane foams.

Comprehensive Study of Ni Nanotubes for Bioapplications: From Synthesis to Payloads Attaching

Due to the Ni nanotubes’ shape anisotropy, low specific density, large specific surface, and uniform magnetic field, they have been offered as carriers for targeted delivery of drug or protein and the process of their formation from synthesis stage to the stage of surface modification and protein attaching has been demonstrated. Some steps to hasten their biomedical application have been applied. First, to have full control over the carrier dimensions and structure parameters, electrodeposition method in pores of polyethylene terephthalate template has been applied. Second, to understand the scope of Ni nanostructures application, their degradation in media with different acidity has been studied. Third, to improve the biocompatibility and to make payloads attachment possible, nanotubes surface modification with organosilicon compound has been carried out. At last, the scheme of protein attaching to the nanostructure surface has been developed and the binding process was demonstrated as an example of the bovine serum albumin.

Study on Application of Organo-Silicon in Papermaking Industry

Organosilicon compound are widely used in pulping and papermaking industry. The quality and capability of paper sheet are distinctly affected by the use of organosilicon. The application of organosilicon used as softening agent, defoamer agent, strengthening agent were introduced one by one in this paper.
