As promising oxygen evolution reaction (OER) catalysts, spinel‐type oxides face the bottleneck of weak adsorption for oxygen‐containing intermediates, so it is challenging to make a further breakthrough in remarkably lowering the OER overpotential. In this study, a novel strategy is proposed to substantially enhance the OER activity of spinel oxides based on amorphous/crystalline phases mixed spinel...
Single atom catalysts (SACs) are highly favored in Li–S batteries due to their excellent performance in promoting the conversion of lithium polysulfides (LiPSs) and inhibiting their shuttling. However, the intricate and interrelated microstructures pose a challenge in deciphering the correlation between the chemical environment surrounding the active site and its catalytic activity. Here, a novel...
The combination of ferroptosis and innovative tumor therapy methods offers another promising answer to the problem of tumors. In order to generate effective ferroptosis in tumor cells, iron‐based nanomaterials are commonly utilized to introduce foreign iron as a trigger for ferroptosis. However, this usually necessitates the injection of larger doses of iron into the body. These exogenous iron increases...
Lysosome‐targeting chimera (LYTAC) links proteins of interest (POIs) with lysosome‐targeting receptors (LTRs) to achieve membrane protein degradation, which is becoming a promising therapeutic modality. However, cancer cell‐selective membrane protein degradation remains a big challenge considering expressions of POIs in both cancer cells and normal cells, as well as broad tissue distribution of LTRs...
Advanced bifunctional electrocatalysts are essential for propelling overall water splitting (OWS) progress. Herein, relying on the obvious difference in the work function of Ir (5.44 eV) and CoMoO4 (4.03 eV) and the constructed built‐in electric field (BEF), an Ir/CoMoO4/NF heterogeneous catalyst, with ultrafine Ir nanoclusters (1.8 ± 0.2 nm) embedded in CoMoO4 nanosheet arrays on the surface of nickel...
2D Selectors
In article number 2310158, Yanpeng Liu, Wanlin Guo, and co‐workers devise a 2D graphene/hBN/WSe2 selector that exhibits outstanding bipolar nonlinearity at room‐temperature. Profiting from well‐designed band alignment and proper tunneling barrier, the selector undergoes direct tunneling at low bias, and Fowler‐Nordheim tunneling at high bias. This proof‐of‐concept demonstration opens...
The integration of one‐selector‐one‐resistor crossbar arrays requires the selectors featured with high nonlinearity and bipolarity to prevent leakage currents and any crosstalk among distinct cells. However, a selector with sufficient nonlinearity especially in the frame of device miniaturization remains scarce, restricting the advance of high‐density storage devices. Herein, a high‐performance memory...
Emergent fermions arising from the excess electrons of electrides provide a new perspective for exploring semimetal states with unique Fermi surface geometries. In this study, a class of unique two‐dimensional (2D) highly anisotropic Dirac fermions is designed using a sandwich structure. Based on the structural design and first‐principles calculations, 2D electride MB (M = Ca/Sr, B = Cl/Br/I) is an...
Thermal interface materials (TIMs) are in desperate desire with the development of the modern electronic industry. An excellent TIM needs desired comprehensive properties including but not limited to high thermal conductivity, low Yong's modulus, lightweight, as well as low price. However, as is typically the case, those properties are naturally contradictory. To tackle such dilemmas, a strategy of...
Adsorption, storage, and conversion of gases (e.g., carbon dioxide, hydrogen, and iodine) are the three critical topics in the field of clean energy and environmental mediation. Exploring new methods to prepare high‐performance materials to improve gas adsorption is one of the most concerning topics in recent years. In this work, an ionic liquid solution process (ILSP), which can greatly improve the...
Droplet‐based triboelectric nanogenerators (D‐TENGs) have recently gained much attention due to their great potential in harvesting energy. However, the output performance of conventional single‐electrode droplet‐based TENGs is limited owing to low induced electrification efficiency. The asymmetric distribution of electric fields on both sides of the electrode edge enhances the electrostatic induction...
Near‐infrared‐II (NIR‐II) imaging has shown great potential for monitoring the pathological progression and deep tissue imaging but is limited to present unmet NIR‐II agent.

In this work, atom‐engineered NIR‐II Au24Cd1 clusters with ultrahigh...
One‐step purification of ethylene (C2H4) from a quaternary gas mixture of C2H6/C2H4/C2H2/CO2 by adsorption is a promising separation process, yet developing adsorbents that synergistically capture various gas impurities remains challenging.

Si Nanodisk Clusters
In article number 2204883, Kai Chen and co‐workers demonstrate a new type of anapole state termed as extrinsic anapole with mode field spreading across the high‐index all‐dielectric nanodisk clusters, unlike the intrinsic one that is confined within individuals. The extrinsic anapole boosts two‐photon‐induced white‐light emission in Si nanodisk clusters.
Nanoparticle clusters provide new degrees of freedom for light control due to their mutual interaction compared with an individual one. Here, the authors demonstrate theoretically and experimentally a type of optical anapole (a nonradiating state) termed as extrinsic anapole, with mode field spreading across Si nanodisk dimers unlike the intrinsic one that is confined within individual nanodisks....
Transition metal nitrides (TMNs) nanostructures possess distinctive electronic, optical, and catalytic properties, showing great promise to apply in clean energy, optoelectronics, and catalysis fields.
