Hydrogen uptake in zirconium alloys is a major limiting factor of nuclear fuel cladding as subsequent hydride precipitation can lead to potential failure via delayed cracking (DHC). The specific mechanisms DHC have been focus earlier research, however there still no clear definition the resulting crystallography and sizes at various temperatures crack propagation. In this work, novel thermo-mec...

The benchmarking of the performance for H2 evolution cobalt diimine-dioxime catalysts is provided based on a comprehensive study their catalytic mechanism. latter follows an ECE'CC pathway with intermediate formation Co(II)-hydride and second protonation possibly at basic site ligand, acting as proton relay. This suggests intramolecular coupling between hydride protonated ligand concentration-i...

Streptavidin-based secondary amine enables organocatalytic hydride reduction.

The first enantioselective organocatalytic hydride reduction has been accomplished. The use of iminium catalysis has provided a new organocatalytic strategy for the enantioselective reduction of beta,beta-substituted alpha,beta-unsaturated aldehydes to generate beta-stereogenic aldehydes. The use of imidazolidinone 2 as the asymmetric catalyst has been found to mediate the transfer of hydrogen ...

among the different reducing agents tributyltin hydride was found to be a powerful reducing agent for the denitration of a series of tertiary and secondary nitroesters. the organotin residues removed from the crude product using saturated potassium fluoride solution. the yield of the reactions was 62-98%.
