ABSTRACT The fabrication of quantum dots (QDs) micro‐patterns, especially those with both µm‐scale high‐resolution and mm‐/cm‐ scale large area uniformity, remains a bottleneck limiting the application of quantum dot light‐emitting diodes (QLEDs). Current strategies have suffered from either low resolution or complicated micro‐template assisted fabrications deteriorating the device performance. H…

ABSTRACT Polymer electrolytes (PEs) are widely regarded as a promising platform for solid‐state batteries (SSBs), offering the potential to simultaneously achieve high energy density with improved safety. However, in current literature, PEs spanning liquid‐percolated gels, liquid‐assisted quasi‐solids, and truly polymer‐governed solids are often indiscriminately grouped as solid polymer electroly…

ABSTRACT Effectively inducing endoplasmic reticulum (ER) stress to initiate cell pyroptosis is promising to elevate cancer immunotherapy, as it avoids immune escape of tumor cells and insufficient differentiation of immune cells. However, it remains a major challenge due to the lack of effective ways to induce ER stress. Herein, we reported the conceptually new electro‐pyroptosis immunotherapy (E…

ABSTRACT Heat dissipation remains a formidable challenge for polytetrafluoroethylene (PTFE) based high‐frequency substrates, as the integration of thermally conductive fillers like hexagonal boron nitride (hBN) is often hindered by the intrinsic chemical inertness and ultra‐low surface energy of PTFE. Herein, a soluble fluoroalkyl end‐capped polyimide (FPI) precursor is developed. The amphipathic…

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.

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. Here, we demonstrate that antiphase boundaries (APBs) in thin-film structures function as …

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. Aluminum battery is an intrinsically safe energy storage device, but can not meet flexible requirements due to the rigid Al foil negative electrode.
