Three-dimensional network of nitrogen-doped carbon matrix
Sep 26, 2022 · Here, we report a Nitrogen-doped graphene/carbon-encapsulated Si nanoparticle/carbon nanofiber composite (NG/C@Si/CNF) prepared by methods of surface modification, electrostatic self-assembly,...
Thermogravimetric analysis (TGA) - Chemistry LibreTexts
Aug 22, 2022 · In thermogravimetric analysis (TGA), a sample is continually weighted while heating, as an inert gas atmosphere is passed over it. Many solids undergo reactions that evolve gaseous byproducts. In TGA, these gaseous byproducts are removed and changes in the remaining mass of the sample are recorded. Three variations are commonly employed:
OH Surface Density of SiO2 and TiO2 by Thermogravimetric Analysis
Dec 4, 2002 · Thermogravimetric analysis (TGA) is investigated for determination of the OH surface density (OH/nm 2) and carbon content of silica and titania powders made by flame aerosol and sol−gel processes.
Silver oxide decomposition mediated direct bonding of silicon …
Jul 11, 2018 · Here, we demonstrate a process for directly bonding metals to silicon-based materials that does not require surface treatment, based on the in situ decomposition of Ag 2 O paste, forming Ag...
