Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems
Advanced Materials Technologies, EarlyView.Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Grinding Management of Rail Profile Based on Abnormal Hunting of High-speed Train
机车电传动, 2020 To study the influence of the polished depth of rail profile at the gauge angle on the low-frequency vibration of high-speed train, a group of rail profiles were obtained by interpolating between the standard CN60 profile and the measured rail profile ...

Advanced Science, EarlyView.The ultra‐short‐acting sedative remimazolam has a sustained therapeutic effect on the core symptoms of VPA‐exposed mice. Remimazolam, a GABA agonist, exerts its therapeutic effects by protecting dopamine neurons in the VTA of VPA‐exposed mice. Meanwhile, ferroptosis is the critical mechanism by which remimazolam protects VTA dopaminergic neurons and ...
