Mechanochromic Organic Materials: Molecular Mechanisms and Multidimensional Applications

Advanced Physics Research, EarlyView.
Mechanochromic (MC) organic materials change color in response to mechanical force. This review elucidates the molecular mechanisms (e.g., aggregation‐induced emission, AIE) and explores their multidimensional applications in sensors, anti‐counterfeiting, biomedical devices, and structural health monitoring, providing a roadmap for future smart ...

Ultra‐High Spin Hall Angle in Sputtered Sb2Te3 Topological Insulators via Pt Interfacial Engineering

Advanced Physics Research, EarlyView.
Topological insulator Sb2Te3 demonstrates exceptional charge‐to‐spin conversion efficiency and thermal stability up to 400°C, showing great promise for spin–orbit torque memory applications. This study achieves high‐quality Sb2Te3 films on silicon substrates through optimized sputtering and introduces an ultrathin Pt interlayer to suppress interfacial ...

Symmetry Control of Mutually Thermoelectric Conversion in Rutile RuO2

Advanced Physics Research, EarlyView.
We demonstrate that crystal symmetry can efficiently modulate mutual thermoelectric conversion. Longitudinal electric‐to‐heat conversion via the anisotropic crystal Peltier effect is observed in a RuO2 single layer without forming P–N junctions, and its dependence on crystal orientation is revealed by lock‐in thermography. Reciprocally, the anisotropic

Controlling Bubble and Skyrmion Lattice Order and Dynamics via Stripe Domain Engineering in Ferrimagnetic Fe/Gd Multilayers

Advanced Physics Research, EarlyView.
The density and ordering of the bubble/skyrmion lattice hosted by Fe/Gd multilayers can be significantly enhanced using an in‐plane field to align the stripe domain state. As a result, the laser‐induced breathing mode dynamics are strongly modified, showing both an increased amplitude and frequency.

Redox‐Dependent Luminescence in a Pentavalent Uranyl Complex

ChemistryEurope, EarlyView.
Redox‐dependent luminescence in a molecular pentavalent uranyl complex supported by a pyridine dipyrrolide pincer ligand is presented. Electrochemical and chemical reduction of the uranyl(VI) species provides a stable uranyl(V) complex that emits blue light from a high‐energy excited state. The anti‐Kasha emission is credited to the presence of “nested”
