Multiple Twinning in Nacre and Aragonite

open access: yesAdvanced Functional Materials, EarlyView.
Electron backscatter diffraction map of a cluster of geologic aragonite, exhibiting single, double, and triple twins. The whole cluster is approximately 2 cm wide. Colors indicate crystal orientations, so that pixels where the a‐, b‐, and c‐axis is perpendicular to the image plane are green, red, and blue, respectively.

Insight into the Internal Structure of Biogenic, Synthetic and Geological Apatite by Electron Microscopy and X‐Ray Scattering

open access: yesAdvanced Functional Materials, EarlyView.
Apatite occurs in many forms in nature, e.g. in teeth and geological minerals. Internally, biological apatite contains nanocrystals that are also found in synthetically prepared calcium phosphate nanoparticles which are used in biomedicine, e.g. for gene and drug delivery and for bone regeneration. Abstract Calcium phosphate is the inorganic component (

Deformation and Degradation in 18650 Li‐Ion Cells Under Freeze‐Thaw Cycling

open access: yesAdvanced Functional Materials, EarlyView.
This study investigates the impact of freezethaw degradation of 18650 cells via combined electrochemical and x‐ray imaging studies. High‐resolution synchrotron X‐ray tomography reveals deformation of the jelly‐roll structure and delamination of electrode active materials in cells cycled at 1C and 4C. These structural changes are quantitatively assessed
