High Pressure-High Temperature, X-Ray Diffraction Apparatus

A tetrahedral-anvil press has been developed that permits x-ray diffraction powder measurements at pressures to 75 kb and temperatures to 1000°C. A counting technique, rather than photographic film, is used for x-ray detection. Sample tetrahedra of compressed LiH, boron, and boron-filled plastic are used in place of the pyrophyllite customarily used for this purpose. Two possible entrance pupil...

High-Temperature X-Ray Powder Diffraction of Secondary Gypsum

Dosimetry of Occupational Radiation around Panoramic X-ray Apparatus

Background: Panoramic imaging is one of the most common imaging methods in dentistry. Regarding the side-effects of ionizing radiation, it is necessary to survey different aspects and details of panoramic imaging. In this study, we compared the absorbed x-ray dose around two panoramic x-ray units: PM 2002 CC Proline (Planmeca, Helsinki, Finland) and Cranex Tome (Soredex, Helsinki, Finland).<br ...

High Pressure Apparatus for in Situ X-ray Diffraction and Electrical Resistance Measurement at Low

High pressure is very effective tool for research of discovering new phenomena and of exploring new materials. For example, some materials undergo superconducting transition under high pressure. Also, it is well known that some insulators become metallic at high pressure. Conversely, there are some singular materials in which metallic state becomes unstable for insulating state at high pressure...
