Ag precipitation and dissolution reactions in the Cu-3 wt.% Al-4 wt.% Ag alloy
(Elsevier B.V., 2006-12-15)
The Ag precipitation and dissolution reactions in the Cu-3 wt.% Al-4 wt.% Ag alloy were studied using isothermal and non-isothermal analyses. The activation energy values, obtained for the Ag precipitation reaction indicated ...
Quantum information from selected elementary chemical reactions: Maximum entangled transition state
(John Wiley & Sons Inc, 2015-10)
Quantum entanglement features exhibited by the reaction path of some selected elementary chemical reactions: hydrogenic abstraction, nucleophilic hydrogenic substitution, three-atom insertion reaction of silylene into ...
Quantitative characterization of the global electrophilicity power of common diene/dienophile pairs in Diels-Alder reactions
(2002)
The global electrophilicity power, ω, of a series of dienes and dienophiles commonly used in Diels-Alder reactions may be conveniently classified within a unique relative scale. Useful information about the polarity of ...
Chlorine evolution during the fusion of chlorofluoroindate glasses
(2005-05-18)
Samples with a composition of 40InF 3-20ZnF 2-5MCl- xBaF 2-ySrF 2, where M=Na, Li and x+y=35 mol%, were prepared. The thermal properties related to the Ba/Sr ratio and to the remaining chlorine content in the glasses were ...
