In most PXRD measurements, a glass sample holder is usually filled with sample. However, other appropriate sample holders should sometimes be selected based on the chemical properties, composition, and shape of the sample, which will allow you to obtain high-quality data with high resolution and low background. Also,

2024年6月12日 · Here we report the discovery of a supramolecular amorphous glass formed by the spontaneous self-organization of the short aromatic tripeptide YYY initiated by non-covalent cross-linking with ...

2025年1月4日 · To identify patterns in Powder X-ray Diffraction (PXRD) data, a neural network called the PXRD Feature Extractor (f PXRD) was developed, which is based on the BERT architecture. PXRD data are represented as curves with diffraction angles on the x-axis and intensities on the y-axis.

2025年3月7日 · Powder X-ray diffraction (pXRD) experiments are a cornerstone for materials structure characterization. Despite their widespread application, analyzing pXRD diffractograms still presents a significant challenge to automation and a bottleneck in high-throughput discovery in self-driving labs.

Powder X-ray diffraction (PXRD) patterns of glass-ceramics and CNT/glass-ceramic composites sintered at different temperatures (* ¼ wollastonite, : ¼ calcium zirconium silicate)....

Powder X-ray diffraction (PXRD) can be used to determine the crystallinity, unit size, and phase purity of the MOF sample through the obtained pattern. The information about unit cell size and phase purity can be extracted through computational models.

2024年3月1日 · In situ precipitation of CsPbBr 3 quantum dots (QDs) in glass is considered as one of the effective methods to overcome its instability and to achieve practical applications. However, it still faces the great challenges of low photoluminescence quantum yield (PLQY), poor thermostability and photostability at present.

2023年8月29日 · When an X-ray is shined on a crystal, it diffracts in a pattern characteristic of the structure. In powder X-ray diffraction, the diffraction pattern is obtained from a powder of the material, rather than an individual crystal.

X-ray diffraction (XRD) is a versatile, non-destructive analytical method to analyze material properties like phase composition, structure, texture and many more of powder samples, solid samples or even liquid samples.
