We propose a new mechanism for the electroreduction of hydrogen in acidic media. The specific model and theoretical calculations are designed for the Pt(111) surface, because this is the only face that exhibits a clear first order phase transition. The bas ...
Novel three-component domino processes to polyheterocycles are developed. Reaction of an allylamine, an aldehyde and an alpha -isocyanoacetamide in methanol at room temp. provides an efficient access to an oxa-bridged tricycle as a single diastereoisomer. ...
We discuss our recently proposed mechanism for the electro-oxidation/reduction on Pt(111) surfaces (J. Electroanal. Chem. 2002, 537, 7) in the presence of sulfuric acid. The bisulfate ion has a large dipole moment and is strongly adsorbed on the positive e ...
he structure and dynamics of the surrounding water were studied through molecular dynamics (MD) simulations for several GdIII polyaminocarboxylate and polyaminophosphonate complexes in aqueous solution. The radial distribution functions (rdf) show that a f ...
We modeled liquid oxygen using ab initio molecular dynamics in which both the atomic structure and the noncollinear magnetic structure evolve without constraints. The atomic structure shows preference for parallel alignment of first-neighbor molecules and ...
The title compound, C6H12N4. C9H16O4, undergoes several thermotropic phase transitions. The crystalline structure is layered, with sheets of azelaic acid linked to sheets of hexamethylenetetramine by hydrogen bonds. In the room-temperature phase, the azela ...
Monoglyme forms a mol. 1:1 adduct with AlBr3 which dissocs. into the ions AlBr2(DME)2+ and AlBr4- in DME, CH2Br2, and CDCl3 as solvents. A hexacoordinated Al center is present in the solid adduct AlBr3.diglyme. The O and Br atoms are arranged in a meridion ...
This work deals with the engineering of a new luminescent complex of lanthanide, able to be specifically grafted onto biological materials and to emit a characteristic light useful in quantifying the concentration of the target molecules. We have based our ...
Since the first facile synthesis of Ru(H2O)(6)(2) was published at the beginning of the eighties, several Ru-II aqueous inorganic and organometallic complexes were described, showing the increasing interest in this kind of compound due to potential ...
N-Salicylideneaniline (SA), C13H11NO, belongs to the large family of aromatic Schiff bases. It is of particular importance owing to its reversible photoreactivity. SA forms two photochromic polymorphs, both with two non-coplanar benzene rings. In addition, ...
