Stereo micro PTV using synchrotron X-ray to measure a micro-tube flow

Dose fractionation in synchrotron radiation x-ray phase micro-tomography.

Phase sensitive x-ray imaging expands the applicability of standard attenuation based techniques by offering several orders of magnitude of increase in sensitivity. Due to the short wavelength, x-ray phase is not directly measurable, but has to be put in evidence by the use of phase contrast techniques. The phase can then be reconstructed from one or several phase contrast images. In this study...

Classification of lead white pigments using synchrotron radiation micro X-ray diffraction

Lead white pigment was used and synthesised for cosmetic and artistic purposes since the antiquity. Ancient texts describe the various recipes, and preparation processes as well as locations of production. In this study, we describe the results achieved on several paint samples taken from Matthias Grünewald’s works. Grünewald, who was active between 1503 and 1524, was a major painter at the beg...

Observation of embolism formation and spreading in plants using synchrotron based X-ray micro computed tomography

Shedding new light on historical metal samples using micro-focused synchrotron X-ray fluorescence and spectroscopy

Synchrotron-based micro-X-ray fluorescence (micro-XRF) and micro-X-ray absorption spectroscopy (micro-XAS) were used in the present study to obtain spatially resolved micro-scale information on elemental composition, trace element distribution, chemical speciation and oxidation state and/or mineral phase distribution within historical iron artefacts dating from the Iron Age to early Medieval Ti...

Cellular Imaging of Cadmium in Resin Sections of Arbuscular Mycorrhizas Using Synchrotron Micro X-ray Fluorescence

Arbuscular mycorrhizal (AM) fungi function as extended roots and take an active part in plant acquisition of nutrients and also soil pollutants, such as heavy metals. The objective of this study was to establish a method to observe the localization of cadmium (Cd) Kα at subcellular levels using X-ray fluorescence (XRF) imaging with a synchrotron irradiation microbeam in resin-embedded sections ...
