Mechanophysical Synthesis of Core/Shell Hybrid Supraparticles
Advanced Materials, EarlyView.Collision‐driven mechanophysical synthesis enables rapid, chemical‐free assembly of core/shell hybrid supraparticles (HSPs) by embedding inorganic nanomaterials onto polymer microparticles. Governed by collision and interfacial energies, this scalable, solvent‐free method accommodates diverse material combinations, allowing multifunctional HSPs for ...

Thermionics in Topological Materials
Advanced Materials, EarlyView.Thermionics is one of the fundamental energy conversion mechanisms in solid state systems. Recent development in topological materials opens new avenues in developing thermionic systems and devices. Due to the linear energy dispersion and topological protection of charge transport, these new materials are promising candidates for high efficiency ...

Long‐Range Spin Transport in Chiral Gold
Advanced Materials, EarlyView.It is demonstrated that in chiral gold film, spin information can be transferred to distances of several microns at room temperature. The conduction of spins is accompanied by the Hall effect that exists without applying an external magnetic field. The spin diffusion length is consistent with the frequency‐dependent Hall effect which indicates spin ...
