SYNTHESIS AND INVESTIGATION OF THIN TiO₂ FILMS, DOPED WITH COPPER NANOPARTICLES

Вестник Северо-Кавказского федерального университета, 2022
Thin films of titanium dioxide, doped with copper nanoparticles, were synthesized by the method of deposition on the rotating substrate. The obtained films were dried at room temperature and at temperature of TiO2 calcination and studied by ellipsometry,

Broadband Transmission Spectroscopy of the super-Earth GJ 1214b suggests a Low Mean Molecular Weight Atmosphere

, 2011
We used WIRCam on CFHT to observe four transits of the super-Earth GJ 1214b in the near-infrared. For each transit we observed in two bands nearly-simultaneously by rapidly switching the WIRCam filter wheel back and forth for the duration of the ...

Efficient Removal of Cd(II) and PB(II) Ions Using Innovatively Functionalized Poly(2,5‐Dihydro‐2,5‐Dimethoxyfuran) for Water Treatment Applications

Journal of Applied Polymer Science, EarlyView.
Synthesis and surface functionalization of pDHMF for enhanced Cd(II) and Pb(II) adsorption from water. ABSTRACT In this work, a novel polymeric adsorbent was synthesized via the cationic polymerization of cis, trans‐2,5‐dihydro‐2,5‐dimethoxyfuran (DHMF), a renewable monomer derived from biomass. To improve its adsorption performance, synthesized poly(2,

SYNTHESIS OF ETHYL FATTY ALKYL ETHERS FROM COCONUT (Cocos nucifera L.) FATTY ALCOHOLS

Annals of Tropical Research, 1987
Ethyl fatty alkyl ethers were synthesized using coconut fatty alcohols as the starting raw materials. The fatty alcohols were converted into their corresponding bromides which were then made to react with ethanolic potassium hydroxide.

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Fiber composition of 190 novel energy cane genotypes and their potential for biorefinery applications

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Energy cane has emerged as a promising feedstock for biorefineries due to its high fiber yield and potential for diversified bioproducts. This study evaluated the fiber composition of 190 energy cane genotypes and assessed their theoretical potential for producing second‐generation (2G) ethanol, polyethylene, and xylitol.
