By using hot pressing, plastically bent Si and Ge wafers in cylindrical shape with keeping mirror surfaces have been obtained. In the present paper, the experimental results obtained by diffractometer with channel-cut monochromater have been discussed from the viewpoint of requirements necessary for curved monochromaters for X-ray optics. It was made clear that by choosing appropriate condition...

Numerical database systems have recently become available online. Their enhanced search capabilities and fast retrieval of data make them a valuable tool in research. In particular, CRYSTDAT which is a search and analysis system for NBS CRYSTAL DATA has proven to be powerful in the identification of crystalline materials. In conjunction with a single-crystal x-ray diffractometer, a qualitative ...

The C-terminal 232-419 amino acids fragment of endonuclease Sau3AI has been successfully expressed in Escherichia coli with 6 His at its N-terminal. After purification and crystallization, one completed 2.8 A data set was collected using a Rigaku R-AXIS IV++ diffractometer. The plate-like crystals belong to orthorhombic space group P2(1)2(1)2(1) with the cell dimension of a = 34.75, b = 76.82, ...

Single crystal neutron diffraction is one of the powerful methods to obtain structure information, including that hydrogen atoms. The IBARAKI biological diffractometer called iBIX a high-performance time-of-flight single elucidate hydrogen, protonation and hydration structures macromolecules in various life processes. Most notably merit observation atoms states. From remarkable results by iBIX,...

With the use of modern single-crystal diffractometers for structure determination, the preliminary photographic study of the diffraction pattern is much abbreviated or even eliminated entirely. The dangers inherent in this omission can be reduced by systematic checking of the automatic features of diffractometer operation, and this requires a full understanding of the methods. This paper (a) de...
