Análise estrutural de complexos derivados de telúrio
(Universidade Federal de Santa Maria, 2011-03-18)
This work describes the synthesis and structural analysis of different kinds of
tellurium based compounds, depicting the preparation of zwitterions, coordination
polymers and also heteronuclear complexes, using ...
Estudo da transição cristalográfica em filme fino de VO2 por difração de raios-x
(Universidade Federal de Santa Maria, 2011-03-28)
In one sample, X-Ray diffractions have been measured as a function of the temperature, in
order to follow the crystallographic transition experienced by VO2 near 68ºC. The results have
been analysed with the aide of a ...
Síntese, reatividade e caracterização estrutural de haletos de telúrio e ariltelurenila com estados de oxidação incomuns ou mistos.
(Universidade Federal de Santa Maria, 2011-03-24)
This work presents a study related to the halogenation of diarylditellurides (RTe)2
in order to obtain tellurium and aryltellurenyl halides with unusual or mixed oxidation
states. Although regarded as essentially unstable, ...
Síntese e caracterização de triazenos e complexos com Hg(II) incluindo arranjos supramoleculares
(Universidade Federal de Santa Maria, 2011-10-14)
This work presents the synthesis of new compounds and their triazenes complexes of
mercury(II). Triazenes have three nitrogen atoms connected in sequence [ N=N N(H) ] and, when
deprotonated, they become good Lewis bases ...
