Advances in Thermochemical Synthesis and Characterization of the Prepared Copper/Alumina Nanocomposites
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
This paper presents thermochemical synthesis of copper/alumina nanocomposites in a Cu-Al2O3 system with 1–2.5 wt.% of alumina and their characterization, which included: transmission electron microscopy: focused ion beam ...
Macroporous monoliths based оn natural mineral sources, clay аnd diatomite
(Science of Sintering, 2020)
Macroporous silica ceramic was obtained using clay and diatomite. Boric acid as a low-cost additive in the amount of 1 wt% was used. These porous materials were obtained at low forming pressure (40-80 MPa) and lower sintering ...
Assessment of trace metal alterations in the blood, cerebrospinal fluid and tissue samples of patients with malignant brain tumors
(Nature Research, 2020)
The pathogenesis of malignant brain tumors (MBTs) should be better understood due to the evident association between prolonged exposure to metals and increased risk of MBTs. The present research aimed to find trace metals ...
A detailed experimental and computational study of monocarbohydrazones
(Elsevier, 2020)
The substituent and solvent effect on intramolecular charge transfer (ICT) of twelve monocarbohydrazones (mCHs) were studied using experimental and theoretical methodology. The effects of specific and non-specific ...
Oxidized humic acids from the soil of heat power plant / Oksidovane huminske kiseline iz toplane
(Serbia : Serbian Chemical Society, 2020)
Humic acids isolated from the soil of a heat power plant (HA-E) contaminated with oil were analyzed by Fourier transform infrared spectroscopy (FTIR). In comparison with a humic acids standard (HA-S), a lack of an intense ...
The effect of the composition of the alloy of ruo2 and pt nanocrystals on intermediate adsorption during methanol oxidation
(Academia Romana, 2020)
A catalytic coating composed of a mixture of RuO2 and Pt
nanocrystals was prepared by a thermal procedure on a titanium
substrate and used for the electrochemical oxidation of methanol.
The adsorption of the intermediate ...
