Multiple Twinning in Nacre and Aragonite
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.

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles
Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

When Error Propagation Fails: A Mini‐Tutorial on Geometric Brownian Motion Simulation
Linear error propagation fails in multiplicative stochastic processes governed by geometric Brownian motion, severely underestimating variance and tail risk. This mini‐tutorial derives the exact log‐normal solution, implements Euler–Maruyama simulation, and introduces a quantitative diagnostic for when simulation is essential.
