Estrutura de vidros fosfatos ternários no sistema Pb-Al metafosfato
(Universidade Federal de São Carlos, 2008-02-26)
In this work, the Pb-Al meta-phosphate glass system (1-x) Pb(PO3)2 xAl(PO3)3
was studied, with the aim of determining the structural effects induced in the glass network by
the substitution of Pb by Al. In the series of ...
Caracterização elétrica e magnética de Fe granular embebido em matriz de ZnSe
(Universidade Federal de São Carlos, 2008-03-13)
Electric and magnetic properties of nanoscopic clusters of iron immersed in Zinc
