Multicolor Optoelectronic Synapse Enabled by Photon‐Modulated Remote Doping in Solution‐Processed Van Der Waals Heterostructures

Advanced Functional Materials, EarlyView.
Multicolor optoelectronic synapses are realized by vertically integrating solution‐processed MoS2 thin‐film and SWCNT. The electronically disconnected but interactive MoS2 enables photon‐modulated remote doping, producing a bi‐directional photoresponse.

Multi‐Faceted Binder Enhancement via Slurry‐Applicable Thiol‐Ene Click Chemistry for Low‐Pressure‐Operable All‐Solid‐State Batteries

Advanced Functional Materials, EarlyView.
Cross‐linked binders with enhanced resiliencies under low operating pressures are designed via in situ thiol‐ene click reactions within slurries. Cross‐linking improves the Young's moduli and elasticities of the styrene‐butadiene rubber binders, effectively mitigating interparticle delamination within the composite cathodes induced by volumetric ...

Unprecedented Spin‐Lifetime of Itinerant Electrons in Natural Graphite Crystals

Advanced Functional Materials, EarlyView.
Graphite exhibits extraordinary spintronic potential, with electron spin lifetimes reaching 1,000 ns at room temperature ‐ over 100 times longer than graphene‐based devices. Magnetic resonance spectroscopy reveals strong anisotropy: out‐of‐plane spins live 50 times longer than their in‐plane counterparts.
