Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes

Advanced Materials, EarlyView.
Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Expanding radiogenic strontium isotope baseline data for central Mexican paleomobility studies.

PLoS ONE, 2020
Radiogenic strontium isotopes (87Sr/86Sr) have long been used in analyses of paleomobility within Mesoamerica. While considerable effort has been expended developing 87Sr/86Sr baseline values across the Maya region, work in central Mexico is primarily ...

Entropy‐Driven Spin Transition in Rare Earth Perovskites Enables Feedback Adsorption for Enhanced Acidic Water Oxidation

Advanced Materials, EarlyView.
A synthetic protocol for fabricating high‐entropy rare earth perovskite oxides with abundant lattice distortions and oxygen vacancies has been developed, representing an emerging platform for anchoring RuO2. High entropy strategy significantly modulated the electronic structures and spin states, inducing a shift in the mechanism from the adsorption ...
