The use of the Rietveld method and pairs distribution function analysis to study the pressure dependence of the trigonal SnSe2 and SnS2 structure
J. C. de Lima, Z. V. Borges, C. M. Poffo +3
A nanostructured trigonal SnSe2 was produced by mechanical alloying, and the effect of high-pressures up to 25.8 GPa on it was investigated. The literature reports refined structur…
Approach combining the Rietveld method and pairs distribution function analysis to study crystalline materials under high-pressure and/or temperature: Application to rhombohedral Bi2Te3 phase
J. C. de Lima, Z. V. Borges, C. M. Poffo +3
An approach combining the Rietveld method and pairs distribution function analysis to study crystalline materials under high pressure or temperature was early proposed by us, and i…
Approach combining the Rietveld method and pairs distribution function analysis to study crystalline materials under high-pressure and/or temperature
J. C. de Lima, Z. V. Borges, C. M. Poffo +3
An approach combining the Rietveld method and pairs distribution function analysis was developed and can help to understand the effect of temperature and/or high-pressure on crysta…
Modeling the amorphous structure of a mechanically alloyed Ti50Ni25Cu25 alloy using anomalous wide-angle x-ray scattering and reverse Monte Carlo simulations
João Cardoso de Lima, Claudio Michel Poffo, Sergio Michielon de Souza +4
An amorphous Ti50Ni25Cu25 alloy was produced by 19 h of mechanical alloying. Anomalous wide angle x-ray scattering data were collected at six energies and six total scattering fact…
New pressure-induced monoclinic β-Sb2Te3 phase with sevenfold symmetry
Sergio Michielon de Souza, Daniela Menegon Trichês, Claudio Michel Poffo +4
A nanometric Sb2Te3 rhombohedral phase was produced from Sb and Te by mechanical alloying for 3 hours and its structural stability was studied by synchrotron X-ray diffraction (XRD…
Structural, Vibrational and Mechanical Studies of Hydroxyapatite produced by wet-chemical methods
K. Donadel, M. C. M. Laranjeira, V. L. Gonçalves +4
Hydroxyapatite samples were produced by two different wet-chemical methods, and characterized by x-ray diffraction, infrared and compression strength measurements. The x-ray diffra…
