2021年1月1日 · Metal oxide nanoparticles were found to be correlated with the configuration and putrefaction process through the heat action of the synthesized samples in good concurrence with thermogravimetric analysis. TGA performed in 27 °C–990 °C at a constant heating rate of 10 °C/minute under air atmosphere.

2022年3月2日 · We have employed a combination of quantitative NMR (qNMR) and thermogravimetric analysis (TGA) to address this problem for commercial cerium, nickel, and iron oxide nanoparticles (NPs) that have been modified to add functional coatings with (3-aminopropyl)triethoxysilane (APTES), stearic acid, and polyvinylpyrrolidone (PVP).

2019年2月15日 · Aluminum nanopowder oxidation is mostly experimentally studied through thermogravimetric analysis (TGA) combined with differential scanning calorimetry (DSC). These types of analyses are very sensible to a variety of parameters such as the heating rate, oxidizing gas composition or sample mass.

2024年8月14日 · A stepwise multi-temperature thermogravimetric analysis (SMT-TGA) method is a rapid and time- and material-efficient measurement procedure for oxidation kinetics over a wide range of temperatures. It is suitable for alloy design and material selection procedures.

2019年6月1日 · Thermal stability studies were made by thermogravimetric analysis (TGA) (Shimadzu, TGA-50). Raman spectra were obtained to estimate the extent of reduction by Raman spectrometer (Renishaw, UK, Renishaw basis series with 514 laser; excitation energy of 2.41 eV) and to study possible defect formation.

2008年7月3日 · The chemical-looping hydrogen generation (CLH) system consists of reduction of metal oxide and water decomposition by oxidizing reduced metal oxide. In the present study, water decomposition by the reduction and oxidation of metal oxide (CuO) was conducted in a thermogravimetric analysis (TGA) system for the CLH process.

A new, rapid and precise thermogravimetric analysis (TGA) technique has been developed for the analysis of AgO-Ag2O-Ag mixtures from silver oxide-zinc cells. The method is described, and the data obtained for cathode material from a variety of sources are presented.

This study explored the potential of cetyltrimethylammonium bromide functionalized graphene oxide (CTAB@GO composite) to remove selenite and selenate from wastewater, given the health hazards ...

2021年1月1日 · Thermogravimetric analysis technique is most widely used for qualitative measurements. The temperature variations in weight obtained by the TGA method can be used for the identification of the composition of nanoparticles, to determine the effect of additives and the assessment of oxidative and thermal stability.
