Structural characterization of the lithium silicides Li15Si4, Li13Si4, and Li7Si3 using solid state NMR
(Royal Society of Chemistry - RSCCambridge, 2012)
Local environments and lithium ion dynamics in the binary lithium silicides Li15Si4, Li13Si4, and Li7Si3 have been characterized by detailed variable temperature static and magic-angle spinning (MAS) NMR spectroscopic ...
Emprego da RMN HR-MAS e análises quimiométricas no reconhecimento e avaliação de soja (Glycine max) geneticamente modificada
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2005-06-29)
The Biotechnology has made possible the development of genetically modified (GM) organisms, including soybean, main Brazilian agricultural product. These GM specimens has been produced by changing some original characteristics ...
Sol-gel preparation of mesoporous Al2O3-SiO2 glasses: structural evolution monitored by solid state NMR
(SpringerNew York, 2014-06)
Glasses along the composition line 0.5Al2O3–xSiO2 (1 ≤ x ≤ 6) were prepared via a novel sol-gel route using tetraethylorthosilicate and aluminum lactate as precursors. The structural evolution from solution to gel to glass ...
Structural investigations of tungsten silver phosphate glasses by solid state NMR, vibrational and X-ray absorption near edge spectroscopies
(Elsevier B.V., 2011-05-01)
Glasses were prepared in the pseudo-binary system (1 - x)AgPO(3)-xWO(3) (0 <= x <= 0.6 mol%). The structural evolution of the vitreous network was studied as a function of composition by thermal analysis, Fourier Transform ...

(Elsevier Science BvAmsterdamHolanda, 2004)
Structural and dynamic characterization of Li12Si7 and Li12Ge7 using solid state NMR
(Academic PressLondon, 2012-04)
Local environments and lithium ion dynamics in the binary lithium silicide Li12Si7, and the analogous germanium compound have been characterized by detailed 6Li, 7Li, and 29Si variable temperature static and magic-angle ...
Synthesis and physicochemical characterization of a novel adsorbent based on yttrium silicate: A potential material for removal of lead and cadmium from aqueous media
(2020-08-01)
A new metallosilicate based on yttrium was synthesized and characterized by XRD, FT-IR, 29Si MAS-NMR, and 89Y MAS-NMR. The mixed framework of the material was confirmed by the detection of distinct chemical shift groups ...
