Liquid metal “sloshing” by the robot's own actuator is proposed to improve the self‐healing performance. The proposed method drastically enhances the healed strength by decomposing the surface oxides and the impurities. The method contributes to the world's first demonstration of active self‐healing behavior performed by a life‐sized legged robot. Self‐

Thermally Responsive Architected Actuators with Programmable Shape Morphing and Tunable Stiffness
A tunable‐stiffness architected morphing structure enables programmable shape transformation and load‐bearing functionality through thermal activation. By tessellating rigid particles with shape memory alloy‐based soft connectors, the system achieves simultaneous morphing and stiffness modulation.

Symmetry Breaking Metamaterial Sleeve Actuators
Metamaterial sleeves are designed to impart to a soft inflatable structure, nonlinear characteristics within the pressure–volume domain. By tuning the unit cells of the metamaterial sleeve, symmetry breaking is achieved during the inflation–deflation cycle.

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect
This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Quantum Anomalies in Condensed Matter
Quantum materials provide a fertile ground in which to test and realize quantum anomalies predicted by quantum field theory. Quantum anomalies need to be canceled globally, however, quantum states with a quantum anomaly can exist at the boundary of topological materials.

Recent Advances in Nitride‐Based Micro‐LEDs for Next‐Generation Display
Nitride‐based Micro‐light‐emitting diode (Micro‐LED) is now spreading into the field of display technology, which has been dominated by liquid crystal display (LCD) and organic LED (OLED). This review focuses on recent developments in Micro‐LED display, including epitaxy and chip processing, mass transfer, driving, bonding, and detection technologies ...

ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Bi‐BiOBr‐P25 TiO2 composite exhibits high and synergistic improvements in the photocatalytic activity for nitrogen oxide (NOx) removal. Herein, we explored the influence of adding carbonaceous material to this composite, namely graphene (G), graphene oxide (GO), carbon nanotubes (CNT) and buckminsterfullerene (F); all at 1 wt.%.
