Procedures using diffuse reflectance spectroscopy for estimating hematite and goethite in Oxisols of São Paulo, Brazil
(2015-07-09)
Abstract This work aims to evaluate the accuracy of different procedures using diffuse reflectance spectroscopy for estimation for iron oxides in the soil. Soil samples were collected at a depth of 0.00-0.20 m in two study ...
X-ray reflectivity of zirconia based sol-gel coatings on borosilicate glasses
(Elsevier B.V., 1999-05-01)
In this work the technique of X-ray reflectometry was applied to study zirconiumsulfate films deposited by sol-gel dip-coating process on a borosilicate glass surface. The influence of withdrawal speed and temperature of ...

Time lags of the kilohertz quasi-periodic oscillations in the low-mass X-ray binaries 4U 1608−52 and 4U 1636−53
(Oxford University PressOxford, 2013)
We studied the energy and frequency dependence of the Fourier time lags and intrinsic
coherence of the kilohertz quasi-periodic oscillations (kHz QPOs) in the neutron-star lowmass
X-ray binaries 4U 1608−52 and 4U 1636−53, ...
Caracterization of thin films by x’pert-pro panalytical difractometer
(Universidad Nacional de Colombia, Bogotá, 2014-09-13)
In this work, the structural characterization of thin films using a conventional diffraction equipment, brand X'Pert PRO PANalytical X-rays is described. A brief review of the theoretical diffraction techniques and X-ray ...
