Chemoselective Ru-Catalyzed Oxidative Lactamization vs Hydroamination of Alkynylamines: Insights from Experimental and Density Functional Theory Studies Abstract: The Ru-catalyzed intramolecular oxidative amidation (lactamization) of aromatic alkynylamines with 4-picoline N-oxide as an external oxidant has been […]
Quantitative evaluation of the surface stability and morphological changes of Cu2O particles Abstract: Cu2O low-index surfaces periodic models have been simulated based on density functional theory. The calculated surfaces energies allowed estimating the morphology by […]
Photoanodes on titanium substrates: one-step deposited BiVO4 versus two-step nano-V2O5 films impregnated with Bi3+ Abstract: One-step deposition of photoelectrochemically active BiVO4 (monoclinic) from a polyethylene glycol (PEG300) precursor paint onto titanium substrates is demonstrated to lead […]
The iron oxyhydroxide role in the mediation of charge transfer for water splitting using bismuth vanadate photoanodes Abstract: The water photo-oxidation to oxygen on iron oxyhydroxide (FeOOH) deposited on a surface of semiconductor materials play a […]
Surface free energy of enamel treated with sodium hexametaphosphate, calcium and phosphate Abstract: Objective: This study evaluated the capacity of sodium hexametaphosphate (HMP) at different concentrations to alter the surface properties of dental enamel in order […]
Writers: M. Congiu and O. Nunes-Neto and M.L. De Marco and D. Dini and C.F.O. Graeff Keywords: Copper sulphide; Solar energy; Counter-electrodes; Ferrocene; Dye solar cells; Abstract: In this work, the application of hexagonal CuS nanoparticle layers as […]
Writers: M M Ferrer, A F Gouveia, L Gracia, E Longo and J Andrés Keywords: morphology, Wulff construction, surface energy, Co3O4, α-Fe2O3, In2O3 Abstract: Essentially, the exposed crystal planes of a given material, which primarily determine their morphology, tremendously […]
