The direct recycling of spent cathode materials is a promising strategy for a sustainable supply chain but remains challenging for industrial-sourced cathode black mass due to its complex morphology and heterogeneous impurities. Here, we report an all‑dry and scalable process that directly regenerates spent LiNi_0.5Co_0.2Mn_0.3O₂ (NCM523) black mass into h…

Lanthanide-doped fluoride nanoparticles with tunable persistent radioluminescence (persistent RL) have emerged as promising scintillators for 3D X-ray delay imaging.

Non-radiative energy loss remains a critical limitation to further improving the efficiency of organic solar cells (OSCs), as charge generation is typically governed by charge-transfer (CT) states that intrinsically suffer from non-radiative recombination. Intra-moiety excitation (i-EX), a delocalized excitation capable of dissociating within acceptor domains, provides an alternative pathway that…

Integrating sensing functions into memristors is promising to realize in-sensor computing with unpreceded energy efficiency and minimized latency. Strain-sensitive memristors gradually draw attention in neuromorphic tactile sensing applications, but still face the sensitivity-response time tradeoff dilemma.

Morphogenesis is a major developmental process that shapes organs in utero through coordinated structural deformations. Outside of simple cellular or animal models, limited models of morphogenesis exist due to the complexity of hierarchical structural change. In development, the embryonic heart undergoes a complex morphogenesis process involving looping, chamber growth, and septation, transformin…

Wearable and deformable electronics must be driven by safe and flexible batteries.
