The National Academies of Sciences, Engineering, and Medicine are private, nonprofit institutions that provide expert advice on some of the most pressing challenges facing the nation and world. Our ...

"Contains all the mineral data cards in the 1980 Mineral powder diffraction file, which were not published in Selected powder diffraction data for minerals, 1974." ...

On these data, the model was accurate about 67 percent of the time. Then, they began testing the model on diffraction patterns that hadn't been solved before. This data came from the Powder ...

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 ...

Non-ambient diffraction is a powerful tool for identifying the effects of temperature, humidity, pressure, or atmosphere on a sample. Materials exposed to non-ambient environments tend to have ...

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.

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 ...

Join this new webinar presented by Mark Bumiller of Entegris titled, Particle Sizing in Additive Manufacturing Powders: SPOS vs. Laser Diffraction Comparison. Additive manufacturing (AM), or ...
