Photoreactor Modeling: Applications to Advanced Oxidation Processes
(Berkeley Electronic Press, 2008-05)
A general methodology for photoreactor analysis and design based on the fundamentals of chemical reaction engineering and radiative transfer in participating media is presented. Three applications in the field of advanced ...
Coupling of Acetaldehyde to Crotonaldehyde on CeO 2-x (111): Bifunctional Mechanism and Role of Oxygen Vacancies
(American Chemical Society, 2019-04)
Selective C-C coupling of oxygenates is pertinent to the manufacture of fuel and chemical products from biomass and from derivatives of C 1 compounds (i.e., oxygenates produced from methane and CO 2 ). Here we report a ...
Metal-free synthesis of 3,5-disubstituted 1H- and 1-aryl-1H-pyrazoles from 1,3-diyne-indole derivatives employing two successive hydroaminations
(Royal Society of Chemistry, 2015-03)
A robust and efficient atom-economic one-pot synthesis of 3,5-disubstituted 1H- and 1-aryl-1H-pyrazoles under base, acid and metal-free reaction conditions, is reported. The transformation conveniently takes place between ...
Interaction of oxidized copper surfaces with alkanethiols in organic and aqueous solvents. the mechanism of Cu2O reduction
(American Chemical Society, 2010-03)
The interaction of 1-octanethiol, 1,8-octanedithiol, 1-hexadecanethiol, and 16-mercaptohexadecanoic acid with polycrystalline copper surfaces was investigated comparatively using forming solutions with polar (0.05 M NaOH ...
Mechanochemical synthesis and characterization of nanocrystalline Ni1-xCoxFe2O4 (0 ≤ x ≤ 1) ferrites
(Elsevier Science SA, 2019-11-30)
Magnetic ferrites Ni1-xCoxFe2O4 are synthesized by means of a simple, clean and scalable route consisting of a solid-state reaction induced by high energy ball-milling between metal salts (Lewis'acids) and sodium hydroxide ...
Lipid signalling mediated by PLD/PA modulates proline and H2O2 levels in barley seedlings exposed to short- and long-term chilling stress
(Elsevier France-editions Scientifiques Medicales Elsevier, 2017-04)
Phospholipase D (PLD) hydrolyses phospholipids to yield phosphatidic acid (PA) and a head group, and is involved in responses to a variety of environmental stresses, including chilling and freezing stress. Barley responses ...
Novel bifunctional mesoporous catalysts based on preyssler heteropolyacids for green pyrrole derivative synthesis
(Molecular Diversity Preservation International, 2018-10-26)
In this paper, we report the synthesis of Preyssler heteropolyacids supported on mesoporous alumina in order to obtain materials with acid–base properties. A series of pyrrole derivatives were synthesized using a suitable ...
Rewiring Chemical Networks Based on Dynamic Dithioacetal and Disulfide Bonds
(Wiley VCH Verlag, 2018-03-23)
The control of the connectivity between nodes of synthetic networks is still largely unexplored. To address this point we take advantage of a simple dynamic chemical system with two exchange levels that are mutually connected ...
A green and reusable catalytic system based on silicopolyoxotungstovanadates incorporated in a polymeric material for the selective oxidation of sulfides to sulfones
(Elsevier Science, 2021-01)
Two vanadium-containing Keggin silicopolyoxotungsto compounds K5SiVW11O40 and K6SiV2W10O40 were synthesized and characterized. They were incorporated in a superporous hydrogel constitute by prop-2-enamide and propenoic ...
Challenges of dye removal treatments based on IONzymes: Beyond heterogeneous Fenton
(Elsevier, 2021-06)
Dyes are recalcitrant organic compounds that generate environmental damage. Heterogeneous Fenton-like catalysts, catalytic systems using reusable solid-state catalysts as an alternative for Fe2+ in solution, have gained ...
