Advanced Functional Materials, Volume 36, Issue 22, 16 March 2026.We demonstrate true random number generator (TRNG) circuits based on a 2D hBN threshold switching memristor integrated with passive components. Leveraging its intrinsic stochastic behavior, the spike generator produces output fluctuations directly converted into random bits via a comparator.

In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque
Advanced Science, Volume 13, Issue 18, 27 March 2026.In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...

Dendrite Formation and Self‐Healing Mechanism in Ionic Liquid‐Based Magnesium Batteries
Advanced Energy Materials, Volume 16, Issue 11, 18 March 2026.This graphical illustration highlights the importance of operating Mg batteries within a safe operating current density (SOCD) range. Beyond this range, Mg batteries are susceptible to dendrite formation. However, when cycling a dendritic cell with a highly thermally stable electrolyte, a self‐heating effect occurs.
