Refinement of anomalous dispersion correction parameters in single-crystal structure determinations

IUCrJ, 2022
Correcting for anomalous dispersion is part of any refinement of an X-ray diffraction crystal structure determination. The procedure takes the inelastic scattering in the diffraction experiment into account.

Vacuum-Ultraviolet Absorption Spectra of Icy C2H4 at 13–60 K

Frontiers in Astronomy and Space Sciences, 2021
The thermal variation of absorption spectra of icy ethene in wavelength range 105–220 nm was measured from 13 to 100 K using a synchrotron as light source. Sublimation of icy ethene began above 62 K, resulting in decreasing absorption.

Regional diversity in the murine cortical vascular network is revealed by synchrotron X-ray tomography and is amplified with age [PDF]

European Cells & Materials, 2018
Cortical bone is permeated by a system of pores, occupied by the blood supply and osteocytes. With ageing, bone mass reduction and disruption of the microstructure are associated with reduced vascular supply.

Correlating STED and synchrotron XRF nano-imaging unveils cosegregation of metals and cytoskeleton proteins in dendrites

eLife, 2020
Zinc and copper are involved in neuronal differentiation and synaptic plasticity but the molecular mechanisms behind these processes are still elusive due in part to the difficulty of imaging trace metals together with proteins at the synaptic level.

Quantifying Microstructural Evolution in Moving Magma

Frontiers in Earth Science, 2020
Many of the grand challenges in volcanic and magmatic research are focused on understanding the dynamics of highly heterogeneous systems and the critical conditions that enable magmas to move or eruptions to initiate.
