In this dissertation were synthetized six compounds, of the which one is free ligand 1- phenyl-3-(4-nitrophenyl) triazene 1-oxide (1) and five are triazenido complexes of [Ni(O2NC6H4NNN(O)C6H5)2(C5H5N)2] (2), [Zn(O2NC6H4 ...
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 ...
