“The powder method has gained a new importance in neutron diffraction owing to the general lack of large specimens for single-crystal methods”. With this brief opening sentence of his landmark paper ...
粉末衍射卡片(Powder Diffraction File)是国际衍射数据中心(International Centre for Diffraction Data)编辑、发行的纯化合物X射线衍射数据库。 The Powder Diffraction File(PDF)粉末衍射卡片是研究物质以及晶体结构的重要工具。它包含已知晶体结构物相的标准数据,可以作为物质定性 ...
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 ...
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 ...
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 X-Ray Analysis Core Lab includes x-ray powder diffraction (XRD) and x-ray fluorescence (XRF) instruments. This lab offers staff operated analysis as well as training. All reservations are made in ...
The fundamental course covers instrumentation; specimen preparation; data acquisition; and live demonstration of qualitative phase analysis. It also provides an opportunity to use the latest ...
This course provides an introduction to Powder X-ray Diffraction (PXRD), aimed at complete beginners. The course is also ideal for analysts or technicians looking for a refresher in these techniques.
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 ...
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.
