Ultrafast Laser‐Induced Interatomic Forces in Magnetostrictive Metals
Advanced Science, EarlyView.This study reports ultrafast changes in the interatomic forces generated by femtosecond laser excitation in magnetostrictive FeGa thin films. This ultrafast process manifests as an optical birefringence signal lasting ≈400 fs. Using a pump‐probe system, the femtosecond evolution of this nonequilibrium interatomic interaction is visualized, providing ...

Photochromic Molybdate for Advancing Anode Capacity of Lithium‐Ion Battery
Advanced Science, EarlyView.Photochromic polyoxomolybdate is first used to enhance the anode capacity and rate performance of Li‐ion batteries. Abstract Decoupling strategies can effectively enhance lithium‐ion battery (LIB) capacity, but suffer from the need for complex equipment, preventing widespread applicability. This work offers, for the first time, a decoupling strategy of

Advanced Science, EarlyView.This work successfully fabricated ion‐conductive hydrogels with low hysteresis and high conductivity using 3D printing technology. By adjusting the component ratios, the properties of the hydrogels can be tuned to meet diverse sensing requirements. Finally, a multimodal sensing sign language recognition system was constructed based on this hydrogel ...

High‐Entropy Chemical Composition Design for Ultrahigh Capacitive Energy Storage
Advanced Science, EarlyView.La‐donor doping suppresses defect charges and reduces domain size via local random fields. Conversely, NaNbO3 addition in BNT‐based ceramics stabilizes the orthorhombic phase. This creates R‐O‐T multiphase polar nanoregions within a cubic matrix, which lowers the energy barrier, delays polarization saturation, and enables a high breakdown strength ...

Advanced Electronic Materials, EarlyView.5 nm HfO2 memristors exhibit a fully reversible, voltage‐controlled transition between filamentary and interfacial switching within the same device. At high voltages, a filament forms and dominates the conduction, whereas at lower voltages the device reversibly returns to interfacial mode without defect accumulation, implying a new reversible ...

Phenomenological modelling of viscoplasticity
Revue de Physique Appliquée, 1988 The essentials of phenomenological modeling of metal deformation behavior at small strain are introduced together with companion experiments which are performed with servocontrolled testing machines and strain measurement on the specimen gage length. Systematic experimentation leads to the viscoplasticity theory based on overstress and its properties ...
