Annals of West University of Timisoara: Physics, 2018 Photocatalytic degradation of organic pollutants from wastewater using titanium dioxide is recognized as an efficient process. To be feasible, this process needs to be solar- or visible light -activated, but, due to its wide band gap energy, titanium ...

Electrochemical Properties of Nonflammable Organo-Fluorine Compounds for Lithium Ion Batteries [PDF]
, 2010 Electrochemical behavior of organo-fluorine compounds with high oxidation stability has been investigated. Oxidation currents of fluorine compound-containing EC/DEC solutions were much smaller than those of EC/DEC and EC/DEC/PC at the higher potentials ...

Can fluorine form triple bonds?
, 2022 A central dogma is that fluorine is the most electro negative element in the PSE and would thusact as a pure electron acceptor. However, to some chemists it is known, that fluorine can bond induality.

Fluorine chemistry at the millennium : fascinated by fluorine /
, 2000 This volume brings together contributions by leading researchers covering a wide scope so characteristic of fluorine chemistry. It was in 1986 that the centennial of the isolation of fluorine by Moissan was celebrated, and much was said at the time about

Organo-sulfur phosphorus chemistry
, 1998 P-organo-substituted dithiadiphosphetane disulfides have been prepared by the reaction of ferrocene and arenes with P4S10. Reaction of these compounds and Lawesson's reagent with alkenes, 2,3-dimethylbutadiene and other compounds gave organo-sulfur ...
