The present work describes the synthesis of a new series of furan-3-carboxamides and 3-aminomethylenedihydrofuran-2-ones, through the reactions of 3-trichloroacetyl furan or furan-3-carbonyl chloride, and 3-trichloroacet ...
Síntese e análise estrutural de haletos de organilcalcogênios ( Se e Te ) com estados de oxidação mistos
(Universidade Federal de Santa Maria, 2007-03-22)
This work describes the synthesis and structural analysis of new organochalcogen halides with mixed oxidation states in the same molecule. Studies in the solid state by X-ray diffraction reveal a general tendency to associate ...
Magnetoimpedância e dinâmica da magnetização em nanoestruturas ferromagneto/Cu (Ag)/ferromagneto
(Universidade Federal de Santa Maria, 2007-08-17)
In this work the static and dynamic magnetic properties are investigated in FM/i/Cu(Ag)/i/FM tri-layer structured samples where FM is the ferromagnetic multilayer and i is the SiO2 isolating layer. All samples have been ...
