Análise por espectroscopia de fotoluminescência de nanotubos de carbono em filmes de sílica e em solução de NaDDBS
(Universidade Federal de Minas GeraisUFMG, 2010-03-12)
This dissertation presents and discusses results of studies of Photoluminescence Spectroscopy (PL) and Raman spectroscopy in samples with Single Wall Carbon Nanotubes (SWNT) in silicamatrix. We also look at maps of ...
Disulfuryl dichloride ClSO2OSO2Cl: a conformation and polymorphism chameleon
(Wiley VCH Verlag, 2018-04)
Disulfuryl dichloride ClSO 2 OSO 2 Cl was characterized byvibrational spectroscopy in the gaseous and liquid phase as well asin the Ar-matrix. By varying the temperature, certain bands could beassigned to several conformers. ...
Photochemistry and Vibrational Spectra of Matrix-Isolated Methyl 4-Chloro-5-phenylisoxazole-3-carboxylate
(American Chemical Society, 2011-02)
Methyl 4-chloro-5-phenylisoxazole-3-carboxylate (MCPIC) has been synthesized, isolated in low temperature argon and xenon matrices, and studied by FTIR spectroscopy. The characterization of the low energy conformers of ...
Vibrational spectra, conformational properties and argon matrix photochemistry of diacetyl diselenide, CH 3 C(O)Se 2 C(O)CH 3
(John Wiley & Sons Ltd, 2016-11)
By oxidation of selenoacetic acid, CH3C(O)SeH, we have prepared the hitherto unknown diacetyl diselenide, [CH3C(O)Se]2. Its vibrational properties were studied experimentally, both in neat liquid (Fourier transform infrared ...
Magnetic and optical investigation of 40SiO(2)center dot 30Na(2)O center dot 1Al(2)O(3)center dot(29-x) B2O3 center dot xFe(2)O(3) glass matrix
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Samples of 40SiO(2)center dot 30Na(2)O center dot 1Al(2)O(3)center dot(29 - x)B2O3 center dot xFe(2)O(3) (mol%), with 0.0 <= x <= 17.5, were prepared by the fusion method and investigated by electron paramagnetic ...
Matrix isolation and low temperature solid state FTIR spectroscopic study of α-furil
(Royal Society of Chemistry, 2006-12)
α-Furil [C4H3O–C([double bond, length as m-dash]O)–C([double bond, length as m-dash]O)–C4H3O] has been isolated in argon and xenon matrices and studied by FTIR spectroscopy, supported by DFT(B3LYP)/6-311++G(d,p) calculations. ...
Chromium speciation in Zirconium-based metal–organic frameworks for environmental remediation
(Wiley, 2020)
Acute Cr(VI)water pollution due to anthropogenic activities is an increasing worldwide concern. The high toxicity and mobility of Cr(VI)makes it necessary to develop dual adsorbent/ion-reductive materials that are able to ...
Enolase from Paracoccidioides brasiliensis: isolation and identification as a fibronectin-binding protein
(Soc General Microbiology, 2009-06-01)
Paracoccidioides brasiliensis yeast cells can enter mammalian cells and may manipulate the host cell environment to favour their own growth and survival. Moreover, fibronectin and several other host extracellular matrix ...
