The results showed that: the surface of the SiO2film was smooth, the average size of the particles, with the non crystalline and disordered structure, was in the range of nanometer. The optimal process parameters were chosen as the sputtering power of 1.8KW and the sputtering time of 10 ...
Pore-structure design The porous structure of nanoscale silicon can accommodate the significant volume expansion of silicon-based electrodes because of its high internal porosity. This porous design increases the specific surface area of silicon, enhancing the wetting of silicon nanomaterials by the electr...
Here we show that the silicon dioxide molecule (SiO2) along with silicon monoxide (SiO) can be efficiently formed via a low-temperature gas phase chemistry even at 10 K. We report the results of a combined crossed molecular beam study and of electronic structure calculations on the reaction...

摘要: Proposes a model for the silicon/silicon dioxide interface. Derivation of silicon/silicon dioxide interfaces; Photoemission spectroscopy of spherosiloxane cluster; Exploration of the implications of assignments for structural models; Consistency of the models with the photoemission data....
Here, we describe a method to improve the monodispersion of SACs using silicon dioxide as a protective layer. The decoration of silicon dioxide serves as a buffer layer for individual nanoparticles, which is not destroyed during the pyrolysis process, ensuring the single-particle dispersion of the...

silicon dioxide- a white or colorless vitreous insoluble solid (SiO2); various forms occur widely in the earth's crust as quartz or cristobalite or tridymite or lechatelierite silica,silicon oxide cristobalite- a white mineral consisting of silica; found in volcanic rocks ...
Test results show that nano-SiO2 additives can not only effectively increase the hydration product (calcium silicate hydrate [C-S-H] gel), but also make the crystal structure denser. Among the three types of nano-SiO2 additive, the SS type can best improve the properties of sludge ash/...
