VIEW, EarlyView.The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Portable X‐Ray Fluorescence in the Assessment of Zinc Along Grizzly Bear Hair
X-Ray Spectrometry, EarlyView.ABSTRACT As a biomarker of past uptake of zinc, hair presents an interesting option since its growth can provide a stored record over time. This study investigates the distribution of zinc in hairs gathered from a series of grizzly bears (Ursus arctos horribilis).

X-Ray Spectrometry, EarlyView.ABSTRACT The diffusion of metal ions in polymer electrolyte membranes is an important parameter for aging and capacity loss in electrochemical cells. Here, the diffusion coefficients of vanadium ions in Nafion membranes are studied. These are important to describe transportation of the ions through the membrane separator in vanadium redox flow ...

Trace Element Analysis in Human Neuroblastoma Cell Spheroids Supplemented With ZnCl2 by Micro‐XRF
X-Ray Spectrometry, EarlyView.ABSTRACT Neuroblastoma, the most common extracranial solid tumor of childhood, is responsible for ~10% of pediatric cancer deaths and has high potential for metastasis. Metals are extremely important in biological processes, and changes in their levels have been correlated with the development of cancerous growth.
