Electrohydraulic Folding Ring Actuators for Radially Contracting Applications
Advanced Science, EarlyView.This work presents an Electrohydraulic Folding Ring Actuator that combines high‐performance electrohydraulic actuation with origami‐inspired folding geometry to achieve constricting radial actuation. This integration yields significant inner lumen constriction, alongside a gripping force capable of holding objects exceeding four times the actuator's ...

Aseismic Capability of Beam-to-Column Joint in RC Frame Under Biaxial Loading
Advances in Civil EngineeringThe aseismic capability of a beam-to-column connection may be lower under identical bidirectional compared to unidirectional loads. However, earthquake excitations are multidimensional and random, so joints may be simultaneously subjected to different ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks
Advanced Science, EarlyView.Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Graphene (0002)/Diamond (111) Heterojunction with High Piezoresistive Response
Advanced Science, EarlyView.Graphene/diamond heterostructures show promise as silicon alternatives for semiconductors, but high‐quality integration is challenging. Thermal electron irradiation enables covalent bonding; lonsdaleite acts as an intermediate. The heterostructure exhibits a high piezoresistive response (gauge factor −1149) associated with electron‐rich layers and ...
