X-ray diffraction data of tibolone Delta(4) isomer (isotibolone)
, 2009 Tibolone is used for hormone reposition of postmenopause women and isotibolone is considered the major degradation product of tibolone. Isotibolone can also be present in tibolone API raw materials due to some inadequate synthesis.

Optimizing electron backscatter diffraction of carbonate biominerals—resin type and carbon coating [PDF]
, 2009 Electron backscatter diffraction (EBSD) is becoming a widely used technique to determine crystallographic orientation in biogenic carbonates. Despite this use, there is little information available on preparation for the analysis of biogenic carbonates ...

Diffraction in grating optical filters with angular-selective light transmission [PDF]
Компьютерная оптика, 2020 The effect of diffraction on the directional light transmittance of grating optical filters designed for smart windows is studied. The filter has an angular selective light transmission due to two thin-film gratings formed by "non-transmissive ...

Surface Plasmons Excited by X-rays in the Surface Layers of Solids
Solids, 2022 The phenomenon of total external reflection of X-rays at a sliding angle of incidence of a beam of incident X-rays is investigated. For metals, a quantitative law of direct dependence of the refractive index decrement on the interplane distance is ...

Influence of annealing on X-ray diffraction of natural alexandrite
, 2002 In this work we present results of X-ray diffraction using powder method, on natural alexandrite samples from Minas Gerais State (Brazil), as a function of a sequence of annealing. From these measurements we determine lattice parameters before (a = 9.405
