Full-scale simulation of high-current vacuum arc in vacuum interrupter under axial magnetic field
AIP AdvancesMost existing studies on vacuum arcs confine the arc to the space directly between the electrodes. Contacts are often slotted to facilitate magnetic field control of the arc, thereby artificially restricting the arc-burning zone and overlooking the ...

Advanced Healthcare Materials, EarlyView.This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

Freeform Fabrication of Layered Halide Perovskite Nanowire Heterojunctions
Advanced Materials, EarlyView.‘All‐at‐once’ freeform fabrication of layered perovskite nanowire heterojunctions is realized by 3D printing employing meniscus‐guided crystallization. The integration of nanoscale additive manufacturing with layered halide perovskites will provide a versatile platform to freely design and realize highly stable perovskite‐based optoelectronic ...
