“…TGA shows the lower thermal stability of PDTPs than that of PEG due to the relatively low thermal stability of the P-O-C moieties. The low T(g)s of these polymers, from −4 to −50 °C, and a lack of PEG crystallites were found by DSC. …”

“…Based on the analysis of the atomic radial distribution function, a model is proposed for the atomic short-range order structure of the a-C:H:SiO(x) coating, and chemical bonds (C–O, C–C, Si–C, Si–O, and Si–Si) are identified. It is shown that the a-C:H:SiO(x) coating does not possess prolonged cytotoxicity in relation to EA.hy926 endothelial cells. …”

“…The high reactivity of the (•)OH with amino acids contained within proteins is responsible for the formation of various covalent bonds (including C–C or C–O–C) between adjacent protein molecules. In the analysis of the formation of protein aggregates, intramolecular electron transfer from the tyrosine moiety to Trp(•) radical should be taken into account. …”
