Fenton chemistry at aqueous interfaces.

In a fundamental process throughout nature, reduced iron unleashes the oxidative power of hydrogen peroxide into reactive intermediates. However, notwithstanding much work, the mechanism by which Fe(2+) catalyzes H2O2 oxidations and the identity of the participating intermediates remain controversial. Here we report the prompt formation of O=Fe(IV)Cl3(-) and chloride-bridged di-iron O=Fe(IV) · ...

Polish chemistry in the century of the discov - ery of polonium and radium

Chemistry International, 1998, Vol. 20, No. 5 sor of Physics at Vienna, Lvov and Cracow universities developed the theory of fluctuations in gases and, independently of Einstein, proposed the theory of Brownian motion. Subsequent experimental confirmation of the Einstein–Smoluchowski equation became one of the final proofs in the kinetic theory of matter. Great achievements in organic chemistry...

The Price of Radium

milligram. As representatives in the British Empire "of the Radium Beige (Union Miniere du Haut Katanga), we would like to have an opportunity of correcting this statement. Previous to the discovery of the rich ores in the Belgian Congo, the standard price for radium element was $110 per milligram, and this price was reduced following the production of radium from the Congo ore to $70, equivale...
