A combined Raman-X-ray powder diffraction study at non-ambient condition

X-Ray Powder Diffraction Metrics

To compare sample data from x-ray diffraction a suitable metric is developed to evaluate the similarity (or dissimilarity) between samples and to compare it to a references. The methodology focuses on the d-lines and uses the intensity measurements indirectly in the algorithm. The resulting d-line distribution and summary statistics of the differences is used to establish whether a true differe...

Detection of breast cancer using non-invasive X-ray diffraction technique of hair: A preliminary study

Background: An early diagnosis of breast cancer relates directly to an accurate treatment plan and strategy. Early detection of breast cancer before its development would be a significant reduction of morbidity and mortality rates. The aim of this preliminary study is to investigate the sensitivity of Wide Angle X-ray diffraction (WAXRD) method on women hair samples of healthy and breast cancer...

Watching the Action: Powder Diffraction at non-ambient conditions

The Bi-Sn-Zn system has not been studied, till present, in all its extension; at least it was not done a complete optimization and assessment of the phase diagram. D. Malakhov et al. [1], as well as N. Moelans et al. [2], have only optimized and assessed the liquid phase of the ternary system due to the lack of data for the thermodynamic properties of terminal solid solutions as well as on thei...

Raman microscopy and X-ray diffraction, a combined study of fibrillin-rich microfibrillar elasticity.

Fibrillin-rich microfibrils are essential elastic structures contained within the extracellular matrix of a wide variety of connective tissues. Microfibrils are characterized as beaded filamentous structures with a variable axial periodicity (average 56 nm in the untensioned state); however, the basis of their elasticity remains unknown. This study used a combination of small angle x-ray scatte...
