Zwitterionic phosphocholine (PC) lipids are highly biocompatible, representing a major component of the cell membrane. A simple mixing of PC liposomes and silica (SiO2) surface results in liposome fusion with the surface and formation of supported lipid bilayers. However, the stability of this bilayer is relatively low because adsorption is based mainly on weak van der Waals force. PC lipids st...
Herein, SiO2 nanotubes have been fabricated via a facile two step hard-template growth method and evaluated as an anode for Li-ion batteries. SiO2 nanotubes exhibit a highly stable reversible capacity of 1266 mAhg(-1) after 100 cycles with negligible capacity fading. SiO2 NT anodes experience a capacity increase throughout the first 80 cycles through Si phase growth via SiO2 reduction. The holl...
BACKGROUND Silica dioxide (SiO2) has been used in various industrial products, including paints and coatings, plastics, synthetic rubbers, and adhesives. Several studies have investigated the genotoxic effects of SiO2; however, the results remain controversial due to variations in the evaluation methods applied in determining its physicochemical properties. Thus, well characterized chemicals an...
Information on the vaporization processes and thermodynamic properties of glass-forming oxide melts in the systems MgO-B2O3-SiO2, CaO-B2O3-SiO2, SrO-B2O3-SiO2, BaO-B2O3-SiO2, PbO-B2O3-SiO2, CdO-B2O3-SiO2, ZnO-B2O3-SiO2, Bi2O3-B2O3-SiO2 and Bi2O3-GeO2-SiO2 together with the earlier obtained data is discussed. These data were obtained by high-temperature mass spectrometric method. Various types o...
