Determination of tellurium at ultratrace levels in drinking water by on-line solid phase extraction coupled to graphite furnace atomic absorption spectrometer
(Elsevier, 2008-12)
In this paper, two time-based flow injection (FI) separation pre-concentration systems coupled to graphite furnace atomic absorption spectrometry (GFAAS) for tellurium determination are studied and compared. The first ...
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 ...
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 ...
Mechanistic study of the addition reaction of TeCl(4) to alkynes: Participation of TeCl(3) centered-radical
(ELSEVIER SCIENCE SA, 2008)
The mechanism of the addition reaction of TeCl(4) to alkynes was indirectly established by the detection of TeCl(3) centered radicals using EPR spin trapping, ESI-MS and ESI-MS/MS characterization. Crown Copyright (C) 2008 ...
NON-ISOTHERMAL STUDIES on CRYSTALLIZATION KINETICS of TELLURITE 20Li(2)O-80TeO(2) GLASS
(Springer, 2009-01-01)
Structural and thermal properties of the 20Li(2)O-80TeO(2) glass were studied using X-ray diffraction analysis and differential scanning calorimetry techniques to understand and control the crystallization process on this ...
Controlled formation of metallic tellurium nanocrystals in tellurite glasses using femtosecond direct laser writing
(Elsevier B.V., 2021-07-01)
Tellurite glasses are considered a potential alternative for applications not achieved by SiO2-based glasses, presenting interesting optical properties, such as high linear and nonlinear refractive indexes, extended optical ...
Enhanced luminescence of Tb(3+)/Eu(3+) doped tellurium oxide glass containing silver nanostructures
(AMER INST PHYSICS, 2009)
We report on energy transfer studies in terbium (Tb(3+))-europium (Eu(3+)) doped TeO(2)-ZnO-Na(2)O-PbO glass containing silver nanostructures. The samples excitation was made using ultraviolet radiation at 355 nm. Luminescence ...
A tellurium-based cathepsin B inhibitor: Molecular structure, modelling, molecular docking and biological evaluation
(Elsevier B.V., 2012-04-11)
The crystallographically determined structure of biologically active 4,4-dichloro-1,3-diphenyl-4-telluraoct-2-en-1-one, 3, shows the coordination geometry for Te to be distorted psi-pentagonal bipyramidal based on a ...
4-Organochalcogenoyl-1H-1,2,3-triazoles: synthesis and functionalization by a nickel-catalyzed Negishi cross-coupling reaction
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
A general method for the synthesis of triazoles containing selenium and tellurium was accomplished via a CuCAAC reaction between organic azides and a terminal triple bond, generated by in situ deprotection of the silyl ...
