Novel electroblowing synthesis of tin dioxide and composite tin dioxide/silicon dioxide submicron fibers for cobalt(ii) uptake. [PDF]

RSC Adv, 2021
Calcination temperature and heating rate markedly affected the structure and morphology of electroblown SnO2/SiO2composite fibers. Compared with bare SnO2fibers, the SiO2component improved the mechanical strength but slightly weakened Co2+uptake.

Weak Localization in Polycrystalline Tin Dioxide Films. [PDF]

Materials (Basel), 2020
The electrical and magnetotransport properties of nanocrystalline tin dioxide films were studied in the temperature range of 4–300 K and in magnetic fields up to 8 T. SnO2−δ films were fabricated by reactive direct current (DC) magnetron sputtering of a tin target with following 2 stage temperature annealing of synthesized samples.

Preparation of V2O5 and SnO2 Nanoparticles and Their Application as Pollutant Removal [PDF]

Journal of Applied Sciences and Nanotechnology, 2021
Vanadium pentoxide and Tin dioxide nanoparticles were prepared by hydrothermal methods to remove methylene blue (MB) and bromothymol blue (BTB) dyes). First the prepared nanoparticles were heated at different temperature (90 oC and 500 oC).

IR spectral manifestation of tin impurity sites in titanium dioxide

Хімія, фізика та технологія поверхні, 2021
It is known that titanium dioxide as photocatalyst has significant drawback - limited absorption spectrum in the ultraviolet region makes it impossible to use solar energy. To expands the absorption spectrum of TiO2, the doping of impurities (metal, non-
