The technique is typically carried out on a single crystal, but because not all substances easily form good quality crystals, powder X-ray diffraction (PXD) is sometimes used instead. Powder X-ray ...

THE classical methods of X-ray crystallography give either the spacings but not the positions of the reflecting planes (if monochromatic radiation is used, as in the rotating crystal and powder ...

Particle size analysis is crucial to quality control and product development in a number of key industries including aerosols, construction, food and beverage, paint and coatings, and pharmaceuticals.

In pharmaceuticals, PXRD is most commonly used to detect traces of polymers. Better detectors and optical technologies are being developed primarily to push the limits of detection (LOD) still lower.

Over the course of its long history, powder diffraction has provided countless insights into the properties of materials. It will continue to do so in the future, but with an emphasis on elucidating ...

X-ray powder diffraction (XRD) is a powerful structural characterization tool that is essentially a two point probe which measures the distance between all pairs of atoms within the diffraction volume ...

This video shows how the X-ray powder diffraction sample preparation, measurement and analysis is now easy with Bruker’s D2 PHASER instrument. The D2 PHASER desktop X-ray diffraction tool enables ...

The new method can determine crystal structures underlying experimental data thus far difficult to analyze. A joint research team led by Yuuki Kubo and Shiji Tsuneyuki of the University of Tokyo has ...

BUFFALO, N.Y. -- A new, more powerful method of determining the details of molecular structure will be the topic of an international workshop to be held May 12-17 at the University at Buffalo.

X-ray crystallography, like mass spectroscopy and nuclear spectroscopy, is an extremely useful material characterization technique that is unfortunately hard for amateurs to perform. The physical ...

With the development of different techniques for the synthesis of nanomaterials, researchers are constantly looking for a more precise instrument for their nanoscale characterization. X-ray ...

Experiments were conducted to establish a laser diffraction-based method for the determination of lactose powder particle size. This was accomplished using a Bettersizer 2600 equipped with a fully ...
