Introduction to single crystal X-ray analysis II. Mounting crystals

Akihito Yamano

During data collection in single crystal structure analysis, a crystal is kept within the X-ray beam and rotated and oriented in various directions for hours to days. Therefore, the crystal mount should satisfy two contradictory conditions: it should hold the crystal steady for a relatively long period of time without...

Size-strain analysis using the fundamental parameter (FP) method

Akihiro Himeda

Crystallite size and strain affect the physical (mechanical, electric, magnetic and optical) properties of materials. It is quite important to quantify size and strain, and to clarify the relationship between them in the field of material science.

The effects of finite crystallite size and lattice strain can be observed as...

Benchtop X-ray diffractometer MiniFlex300 / MiniFlex600

In January 2012, Rigaku released the MiniFlex300 and the MiniFlex600, the latest models in the MiniFlex benchtop XRD series. The numerical designations indicate the generator performance of these systems, 300 W and 600 W respectively.

MiniFlex diffractometers are widely used in a variety of fields, such as ceramics, minerals, inorganic...

Small angle X-ray scattering Kratky camera system

Small-angle X-ray scattering (SAXS) is an important technique for generating low resolution structures of proteins in native solution. Moreover, SAXS provides information on aggregation, folding, unfolding, assembly and conformational changes of proteins in solution despite of the low resolution. BioSAXS-1000 is a two dimensional compact Kratky camera for SAXS measurements...
