Tough Injectable Hydrogels Enabled by Integrating Rigid Homogeneous Framework With Flexible Chains
Tough injectable hydrogels are constructed by integrating a rigid, homogeneous hyaluronic acid framework with flexible long‐chain connectors. This framework–flexible structure simultaneously enhances network uniformity and promotes effective energy dissipation by enlarging plastic deformation zones under compression.

Online Identification and Verification of the Elastic Coupling Torsional Stiffness
To analyze the torsional vibration of a diesel engine shaft, the torsional stiffness of the flexible coupling is a key kinetic parameter. Since the material properties of the elastic element of the coupling might change after a long-time operation due to

We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Effects of adjusting ring and spring stiffness on fluid dynamics of steam spring-loaded safety valve
As the most typical direct-loaded safety valves, spring-loaded safety valves are automatically opened by fluid pressure. Their stable and reliable dynamic characteristics are vital for overpressure protection in nuclear power plants.

The influence of suction changes on the stiffness of railway formation
Despite compacted soils being unsaturated, geotechnical design is predominantly based on saturated soils,despite it being known that differences exist between the behaviour of saturated and unsaturated soils.Suction in soils has been shown to increase ...

Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks
