Lithium-lanthanum double chromates
(1993-11-12)
Synthesis and crystallographic data are reported for low and high temperature forms of LiLa(CrO4)2. The compounds are closely related to lamellar rare earth phosphates and arsenates of sodium and to RbLu(CrO4)2. Lattice ...

Estudos estruturais de pequenas e médias moléculas por difração de raios-x em monocristais
(Universidade Federal de Minas GeraisUFMG, 2003-05-23)
Five compounds, three organic and two organometallic, were studied by x-ray diffraction in single crystals and their structure was successfully determined in four of five compounds. The measurements were made in diverse ...

Structure determination of the intermediate tin oxide Sn304 by precession electron diffraction
(Oldenbourg Verlag, 2010-03)
The structure of an intermediate form of tin oxide was investigated by precession electron diffraction. The results support a revised version of a layered, vacancy-ordered structure for Sn304 proposed in the preceding ...
Use of molecular dynamics simulations to estimate the solubility of menadione in supercritical CO2 using Chrastil's model
(2017)
The binary system of menadione in explicit supercritical carbon dioxide (SC-CO2) was studied using molecular dynamics (MD) simulations, with the objective to understand the nature of interactions between menadione and ...

Thermal properties of 2:1 bismuth borate: Temperature-dependent characterizations of lone electron pairs
(Wiley Blackwell Publishing, Inc, 2018-11)
Applications of bismuth borate ceramics require understanding of the microscopic features, leading to macroscopic behaviors such as thermal expansion. We report the structural and spectroscopic features of Bi4B2O9 between ...
