Electrochemically reversible conversion of I2/I− redox couple in a controllable iodine speciation manner is the eternal target for practical metal‐iodine batteries. This contribution demonstrates an advanced polyiodide‐free Zn‐I2 battery achieved by the bidirectional confined redox catalysis‐directed quasi‐solid iodine conversion. A core‐shell structured iodine cathode is fabricated by integrating...
The robust and scalable oxygen evolution electrocatalysts that can deliver high current densities at low applied potential is a great challenge for the large‐scale industrial application in hydrogen production. Here, the preparation of a grain‐boundary‐rich Ni‐Fe (oxy)hydroxide catalyst on Ni foam is reported using a scalable coating approach followed by a chemical precipitating treatment. This facile...
Synaptic devices that mimic biological synapses are considered as promising candidates for brain‐inspired devices, offering the functionalities in neuromorphic computing. However, modulation of emerging optoelectronic synaptic devices has rarely been reported. Herein, a semiconductive ternary hybrid heterostructure is prepared with a D‐D’‐A configuration by introducing polyoxometalate (POM) as an...
Lithium (Li) metal anode (LMA) is highly considered as a desirable anode material for next‐generation rechargeable batteries because of its high specific capacity and the lowest reduction potential. However, uncontrollable growth of Li dendrites, large volume change, and unstable interfaces between LMA and electrolyte hinder its practical application. Herein, a novel in situ formed artificial gradient...
Targeted protein degradation (TPD) is an emerging therapeutic strategy with the potential of targeting undruggable pathogenic proteins. After the first proof‐of‐concept proteolysis‐targeting chimeric (PROTAC) molecule was reported, the TPD field has entered a new era. In addition to PROTAC, numerous novel TPD strategies have emerged to expand the degradation landscape. However, their physicochemical...
Adequately harvesting all excitons in a single molecule and inhibiting exciton losses caused by intermolecular interactions are two important factors for achieving high efficiencies thermally activated delayed fluorescence (TADF). One potential approach for optimizing these is to tune alignment of various excited state energy levels by using different doping concentrations. Unfortunately, emission...
2D lamellar materials can offer high surface area and abundant reactive sites, thus showing an appealing prospect in photocatalytic hydrogen evolution. However, it is still difficult to build cost‐efficient photocatalytic hydrogen evolution systems based on 2D materials. Herein, an in situ growth method is employed to build 2D/2D heterojunctions, with which 2D Ni‐based metal–organic layers (Ni‐MOLs)...

Three‐dimensional conductive carbon framework together with the expanded interlayer spacing of titanate hierarchical hollow spheres via the pillared Mg2+ ions expose...
Layered titanates are of great potential for hybrid Na‐ion capacitors (NICs). However, the poor conductivity and sluggish reaction kinetics are the critical issues for the practical applications of titanates. Herein, an approach to synthesize magnesium titanate hierarchical hollow spheres embedded in carbon nanofibers (denoted as MTO@C) by electrospinning coupled with interlayer engineering processes...
Conjugated polymers (CPs) are capable of coordinating the electron coupling phenomenon to bestow powerful optoelectronic features. The light‐harvesting and light‐amplifying properties of CPs are extensively used in figuring out the biomedical issues with special emphasis on accurate diagnosis, effective treatment, and precise theranostics. This review summarizes the recent progress of CP materials...
Aqueous zinc‐ion batteries (AZIBs) are regarded as one of the most promising alternative technology to lithium‐ion batteries on account of their low flammability and cost‐benefits. Among various cathode materials in AZIBs, environment‐friendly and sustainable organic electrode materials stand out owing to their structural diversity and tunability. However, their limited rate capability and cycle stability...
Direct tracing of small extracellular vesicle (sEV) cargoes holds unprecedented importance for elucidating the mechanisms involved in intercellular communication. However, high‐fidelity determination of sEVs’ molecular cargoes in situ has yet to be achieved due to the difficulty in transporting molecular probes into intact sEVs.
