Fast diffraction-enhanced imaging using continuous sample rotation and analyzer crystal scanning
Autor: Thet Thet Lwin, Masahide Kawamoto, Akio Yoneyama
Publikováno v: Journal of Synchrotron Radiation. 27:468-471
Diffraction-enhanced imaging (DEI) has high sensitivity and a wide dynamic range of density and thus can be used for fine imaging of biological and organic samples that include large differences in density. A fast DEI method composed of continuous fa

Novel Zeff imaging method for deep internal areas using back-scattered X-rays
Autor: Akio Yoneyama, Rika Baba, Masahide Kawamoto
Publikováno v: Scientific Reports
Scientific Reports, Vol 9, Iss 1, Pp 1-7 (2019)
Elemental kinds, composition ratios, effective atomic number (Zeff), and spatial distributions are the most basic information on materials and determine the physical and chemical properties of materials. X-ray fluorescence analysis have conventionall

Publikováno v: Acta Crystallographica Section D: Biological Crystallography
The tertiary structure of a β-lactamase derived from the halobacterium Chromohalobacter sp. 560 (HaBLA) was determined by X-ray crystallography. Three unique Sr2+-binding sites and one Cs+-binding site were discovered in the HaBLA molecule.

X-ray Diffraction of Protein Crystal Grown in a Nano-liter Scale Droplet in a Microchannel and Evaluation of Its Applicability
Autor: Saori Yoshizuka, Masahide Kawamoto, Masatoshi Maeki, Kenichi Yamashita, Masaya Miyazaki, Hiroshi Yamaguchi, Hiroyuki Nakamura, Hideaki Maeda
Publikováno v: ResearcherID
We describe the technical aspects of the in-situ X-ray diffraction of a protein crystal prepared by a nanodroplet-based crystallization method. We were able to obtain diffraction patterns from a crystal grown in a capillary without any manipulation.
