Síntese e caracterização estrutural de polialetos e compostos zwitteriônicos derivados de diteluretos de diarila
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2016-06-22)
The present work describes the synthesis and structural elucidation of ten new tellurium halide starting from diaryl ditellurides (aryl group = 2-piridine or N,N-dimethylbenzilamine). The compounds and starting material ...
Enhanced luminescence of Tb3+/Eu3+ doped tellurium oxide glass containing silver nanostructures
(American Institute of Physics (AIP), 2009-05-15)
We report on energy transfer studies in terbium (Tb3+)-europium (Eu3+) doped TeO2-ZnO-Na2O-PbO glass containing silver nanostructures. The samples excitation was made using ultraviolet radiation at 355 nm. Luminescence ...

(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 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 ...
A glimpse on biological activities of tellurium compounds
(Academia Brasileira de Ciências, 2009-09-01)
Tellurium is a rare element which has been regarded as a toxic, non-essential trace element and its biological role is not clearly established to date. Besides of that, the biological effects of elemental tellurium and ...
Enhanced optical properties of germanate and tellurite glasses containing metal or semiconductor nanoparticles
(2013-05-13)
Germanium- and tellurium-based glasses have been largely studied due to their recognized potential for photonics. In this paper, we review our recent studies that include the investigation of the Stokes and anti-Stokes ...

Practical synthesis of chiral beta-telluro amines by ring-opening reaction of aziridines
(ELSEVIER SCIENCE SA, 2009)
A set of chiral beta-tellurium amines and their selenium and sulfur-containing derivatives have been efficiently synthesized in good to excellent yields via the ring-opening reaction of chiral aziridines by chalcogen ...
The influence of Tellurium an Folic Acid Adminitration on Coping Behavioural Parameters in Maturing Rats: Transgenerational effects
(Austin Publishing Group, 2019-11)
A previous study of our laboratory have shown that Tellurium (Te), a metalloid with low concentrations in soil and water in the earth, is able to modify important behavioural parameters related to cognitive functions when ...
