Low-cost disposable high-pressure setup for in situ X-ray experiments

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...

Cost-effective upgrade of a focusing system for inelastic X-ray scattering experiments under high pressure

Inelastic X-ray scattering (IXS) is a powerful technique capable of probing the dynamic behavior and electronic structure of materials. For IXS experiments under high pressure up to the megabar range using state-of-the-art diamond-anvil-cell technology, the sample volume is limited to the order of 1 x 10(-3) mm(3) for which a beam focus of the same order and less is often required. In this pape...

A Newly Developed High-temperature Chamber for in Situ X-ray Diffraction: Setup and Calibration Procedures

High-pressure instrument for small- and wide-angle x-ray scattering. II. Time-resolved experiments

An instrument to facilitate smalland wide-angle x-ray scattering measurements of samples under elevated hydrostatic pressures or exposed to pressure jumps is described. Pressure from atmospheric up to 0.35 GPa is produced by a motor-driven, piston-type generator and transferred through a network containing pressurizing liquid to a sample cell. The cell, with the optical path length of 1.6 mm, h...

In-situ high-pressure powder X-ray diffraction study of α-zirconium phosphate.

The high-pressure structural chemistry of α-zirconium phosphate, α-Zr(HPO4)2·H2O, was studied using in-situ high-pressure diffraction and synchrotron radiation. The layered phosphate was studied under both hydrostatic and non-hydrostatic conditions and Rietveld refinement carried out on the resulting diffraction patterns. It was found that under hydrostatic conditions no uptake of additional wa...
