설명

일반 설명

Study of silicon-silicon dioxide structure at liquid nitrogen temperature by electron spin resonance spectra has been investigated. Diffusion coefficient and solubilities of several metals (Ag, Cu, Au, Pd, and Ti) in silicon dioxide have been discussed. Microcontact printing of self-assembled monolayers (SAMs) of alkylsiloxanes on the surface of silicon dioxide has been reported. Separation and characterization of silicon dioxide (SiO₂) nanostructures in dietary supplements marketed in products specifically targeted for women has been proposed.

애플리케이션

Silicon dioxide may be employed as insulating layer on top of the silicon in the fabrication of gold electrode, used for flow injection amperometric detection of organophosphorus (OP) nerve agents.
