Characterization of a Pt mirror to be used to deflect synchrotron radiation beam onto Langmuir monolayers
(Wiley-Blackwell, 2015-05-01)
A homemade mirror for X-rays has been built to prepare a diffraction beamline for liquid surface diffraction and scattering measurements. This simple approach is in operation at the XRD2 bending-magnet beamline at the ...
X-ray scattering processes and chemometrics for differentiating complex samples using conventional EDXRF equipment
(http://dx.doi.org.ez10.periodicos.capes.gov.br/10.1016/j.chemolab.2005.01.001, 2005)
Mild variations in organic matrices, which are investigated in this work, are caused by alterations in X-ray Raman scattering. The multivariate approaches, principal component analysis (PCA) and hierarchical cluster analysis ...
Analysis of phosphorous content in cancer tissue by synchrotron micro-XRF
(Pergamon-Elsevier Science Ltd, 2021-02)
In the present work, an analytical procedure for spatial quantification of phosphorous in cancerous tissues by micro-XRF was developed. This new methodology based on fundamental parameter approach consists of evaluating ...
Mass fractal characteristics of sonogels prepared from sonohydrolysis of tetraethoxysilane with additions of dimethylformamide
(Elsevier B.V., 2007-02-01)
Wet silica gels with similar to 1.4 x 10(-3) mol SiO2/cm(3) and similar to 90 vol.% liquid phase were prepared from the sonohydrolysis of tetraethoxysilane (TEOS) with different additions of dimethylformamide (DMF). Aerogels ...

Synchrotron X-ray diffraction characterization of healthy and fluorotic human dental enamel
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
With the introduction of fluoride as the main anticaries agent used in preventive dentistry, and perhaps an increase in fluoride in our food chain, dental fluorosis has become an increasing world-wide problem. Visible signs ...
Depth Analysis of Chemical Environments using Resonant Raman Spectroscopy in Total Reflection Geometry
(Brazilian Association for Synchrotron Light Technology, 2010-06)
Total Reflection of X-rays is a largely proved spectroscopic technique that allows the study of material surfaces. As the refractive index is less than unity, X-rays incident on a material are, theoretically, totally ...
