Synthesis and UV/Vis spectroscopic properties of new [2-(N,N-dialkylamino)-1,3-dithiolium-4-yl]phenolates
Autor: Mihail Lucian Birsa, Dumitru Ganju
Publikováno v: Journal of Physical Organic Chemistry. 16:207-212
In weak alkaline aqueous medium, 4-(hydroxyphenyl)-2-(N,N-dialkylamino)-1,3-dithiolium salts led to the corresponding dipolar betaines. These compounds were described as zwitterionic phenolates with an intramolecular charge-transfer UV/Vis absorption

Radiolytic output of hydrogen as environmentally friendly energy vector
Autor: Alexandru Cecal, Ada Macovei, Oana Roxana Hauta, Gabriela Apostolescu, Dumitru Ganju
Publikováno v: Scopus-Elsevier
This study deals with the radiolytical decomposition of water molecules, in the presence of some catalysts, getting out hydrogen as unpolluting and cheaper energy vector. Instead of the spent nuclear fuel elements taken out from nuclear power plants,
