Suppressing Diffraction-Related Intensity Losses in Transmissive Single-Crystal X-ray Optics
Crystals, 2021 The highest-quality X-ray optics can be made of single-crystal materials such as silicon, germanium, or, even better, diamond. Unfortunately, such X-ray optics have one drawback: diffraction losses or the “glitch effect”.

Characterisation of very thin epitaxial layers by high resolution x-ray diffraction [PDF]
, 1989 X-rays can be used as a sensitive, non-destructive probe for the characterisation of semiconductors. The energy and wavelength of X-rays is such that structural information down to the Ảngstrom level can be yielded with a depth penetration of several ...

FEBS Open Bio, EarlyView.The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

High resolution X-ray diffraction and topography of Bragg case interferometers [PDF]
, 1994 In the first chapter a brief overview of the principles and techniques of high resolution X-ray diffraction and topography is presented. Since the best analysis of the measurement is given by simulating the experimental results with predictions based on ...

FEBS Open Bio, EarlyView.The crystal structure of Borrelia burgdorferi nicotinamidase (PncA/BBE22) reveals the correct full‐length protein initiated from a non‐canonical AUU start codon. The structure validates previous biochemical findings and resolves a long‐standing annotation error, demonstrating that the truncated database sequence is structurally incompatible with the ...

Nonlinear optical behaviour of bis (cytosinium) tartarate monohydrate single crystal
Chemical Physics Impact, 2022 A nonlinear optical single crystal of bis (cytosinium) tartarate monohydrate (BCTM) was grown by slow evaporation method at room temperature. Single crystal X-ray diffraction study revealed their cell parameters and corresponding space group.

X-ray diffraction by phospholipid monolayers on single-crystal silicon substrates [PDF]
Proceedings of the National Academy of Sciences, 1983 Monolayers of dipalmitoyl phosphatidylcholine have been transferred from an air-water interface to single-crystal silicon wafers previously alkylated with octadecyltrichlorosilane. By using synchrotron radiation it has been found possible to observe diffraction by single-crystal regions of these monolayers with negligible background scattering from the

High resolution double crystal X-ray diffractometry and topography of III-V semiconductor compounds [PDF]
, 1991 Double crystal diffractometry and topography are now routinely used in many laboratories for the inspection of epitaxially grown devices. However the trend towards thinner layers and more complex structures requires the continued development of novel ...
