Perovskite photodetectors with polarization‐sensitive properties have gained significant attention due to their potential applications in fields such as imaging and remote sensing. Most perovskite photodetectors concentrate on iodine (I) or bromine (Br)‐based materials, primarily due to their straightforward fabrication techniques. The utilization of chloride (Cl)‐based perovskites with wider bandgaps,...
Twisting has recently been demonstrated as an effective strategy for tuning the interactions between particles or quasi‐particles in layered materials. Motivated by the recent experimental synthesis of pentagonal NiN2 sheet [ACS Nano 2021, 15, 13539], for the first time, the response of phonon coherence to twisting in bilayer penta‐NiN2, going beyond the particle‐like phonon transport is studied....
Sodium‐ion batteries (SIBs) are expected to replace partial reliance on lithium‐ion batteries (LIBs) in the field of large‐scale energy storage as well as low‐speed electric vehicles due to the abundance, wide distribution, and easy availability of sodium metal. Unfortunately, a certain amount of sodium ions are irreversibly trapped in the solid electrolyte interface (SEI) layer during the initial...
The interface between the perovskite and electron‐transporting material is often treated for defect passivation to improve the photovoltaic performance of devices. A facile 4‐Acetamidobenzoic acid (containing an acetamido, a carboxyl, and a benzene ring)‐based molecular synergistic passivation (MSP) strategy is developed here to engineer the SnOx/perovskite interface, in which dense SnOx are prepared...
With the pursuit of high‐energy‐density for lithium‐ion batteries (LIBs), the hidden safety problems of batteries have gradually emerged. LiNixCoyMn1−x−yO2 (NCM) is considered as an ideal cathode material to meet the urgent needs of high‐energy‐density batteries. However, the oxygen precipitation reaction of NCM cathode at high temperature brings serious safety concerns. In order to promote high‐safety...
Nano Cell Cycle Checkpoint Inhibitors
In article number 2300736, Daishun Ling, Fangyuan Li, and co‐workers demonstrate that ultra‐small iron oxide nanoparticles (IONPs) can serve as a selective nano cell cycle checkpoint inhibitor (NCCI) to catalyze the intracellular H2O2 into abundant ·OH, cleave heat shock protein 90 (Hsp90), and thus induce the degradation of the client protein ATR/CHK1, leading...
Cell cycle checkpoint activation promotes DNA damage repair, which is highly associated with the chemoresistance of various cancers including acute myeloid leukemia (AML). Selective cell cycle checkpoint inhibitors are strongly demanded to overcome chemoresistance, but remain unexplored. A selective nano cell cycle checkpoint inhibitor (NCCI: citric acid capped ultra‐small iron oxide nanoparticles)...
Mixed matrix membranes (MMMs), conjugating the advantages of flexible processing‐ability of polymers and high‐speed mass transfer of porous fillers, are recognized as the next‐generation high‐performance CO2 capture membranes for solving the current global climate challenge. However, controlling the crystallization of porous metal‐organic frameworks (MOFs) and thus the close stacking of MOF nanocrystals...

In article number 2208177, Ming‐Jie Yin, Quan‐Fu An, and co‐workers propose a “confined swelling coupled solvent controlled crystallization” strategy to rapid preparation of mixed matrix membrane for CO2 capture. The fabricated membrane exhibits 4‐fold enhancement in CO2 permeability, benefiting from the high ZIF‐8 loading creating additional speedy mass transfer channel for...
The Ti3C2Tx film with metallic conductivity and high pseudo‐capacitance holds profound promise in flexible high‐rate supercapacitors. However, the restacking of Ti3C2Tx sheets hinders ion access to thick film electrodes. Herein, a mild yet green route has been developed to partially oxidize Ti3C2Tx to TiO2/Ti3C2Tx by introducing O2 molecules during refluxing the Ti3C2Tx suspension. The subsequent...
Sustainable production of hydrogen from seawater electrolysis has attracted much attention in recent years. Considering that Cl‐ might corrode metal substrate by crossing through the covered catalyst, the conventional Ni(II)Fe(III)‐layered double hydroxide (NiFe‐LDH) loaded on metal substrate, as a favorable oxygen evolution catalyst, cannot be directly used for seawater electrolysis. Herein, an anti‐corrosion...

In article number 2203852, Jie Sun and co‐workers demonstrate that PO43− intercalation in Ni(II)Fe(III)‐layered double hydroxide (NiFe‐LDH) can prevent the Ni substrate from Cl− corrosion by electrostatic repulsion. The anode stability time of seawater electrolysis can be improved more than 100 times by the intercalated PO43−.
High‐capacity Ni‐rich layered oxides are considered as promising cathodes for lithium‐ion batteries. However, the practical applications of LiNi0.83Co0.07Mn0.1O2 (NCM83) cathode are challenged by continuous transition metal (TM) dissolution, microcracks and mixed arrangement of nickel and lithium sites, which are usually induced by deleterious cathode–electrolyte reactions. Herein, it is reported...
Zinc metal has a severe dendrite issue caused by the uneven Zn plating/stripping during continual cycles, which hinders the practical application of ZIBs. The surficial atomic structure of zinc anode plays a decisive role in solving dendrites and improving the electrochemical performance.
