Chiral Discrimination and Mechanistic Study of Enantiomers R-1,1'-Bi-2-naphthol and S-1,1'-Bi-2-naphthol in Briggs-Rauscher Oscillatory Chemical System

This study demonstrates that the enantiomers R-BINOL and S-BINOL can be qualitatively discriminated by their distinct inhibition times in a nickel-catalyzed Briggs–Rauscher oscillatory system, a difference attributed to their varying efficiencies in scavenging hydroperoxyl radicals via a free radical controlled autoinhibition mechanism.

Modelling of Reaction Between Magnetite and Uranium Under Beishan Groundwater Conditions

This study utilizes PHREEQC modeling to demonstrate that magnetite effectively reduces U(VI) to U(IV) in Beishan groundwater, promoting uraninite precipitation and reducing uranium mobility, particularly at higher temperatures and when using appropriate thermodynamic databases, although low uranium concentrations may hinder precipitation.
