Oxygen reduction reaction (ORR) is the key reaction on cathode of rechargeable zinc–air batteries (ZABs). However, the lack of protons in alkaline conditions limits the rate of ORR. Herein, an activating water strategy is proposed to promote oxygen electrocatalytic activity by enhancing the proton production from water dissociation. FeP nanoparticles (NPs) are coupled on N‐doped wood‐derived catalytically...
Aqueous alkaline rechargeable nickel‐zinc (Ni–Zn) batteries possess great potential for large‐scale energy storage systems because of their high output voltage, cheap cost, and intrinsic safety. However, the practical applicability of Ni–Zn batteries has been limited by traditional Ni‐based cathodes with low capacity and poor cycle stability. Rational design of electrode structure and composition...
Suckerin in squid sucker ring teeth is a block‐copolymer peptide comprised of two repeating modules—the alanine and histidine‐rich M1 and the glycine‐rich M2. Suckerin self‐assemblies display excellent thermo‐plasticity and pH‐responsive properties, along with the high biocompatibility, biodegradability, and sustainability. However, the self‐assembly mechanism and the detailed role of each module...
Polarization‐sensitive photodetectors based on van der Waals heterojunctions (vdWH) have excellent polarization‐resolved optoelectronic properties that can enable the applications in polarized light identification and imaging. With the development of optical microcomputer control systems (OMCS), it is crucial and energy efficient to adopt the self‐powered and polarization‐resolved signal‐generators...
Magnetic micro‐/nanoparticles are extensively explored over the past decade as active diagnostic/therapeutic agents for minimally invasive medicine. However, sufficient function integration on these miniaturized bodies toward practical applications remains challenging. This work proposes a synergistic strategy via integrating particle functionalization and bioinspired swarming, demonstrated by recombinant...
Posterior capsular opacification (PCO) is the leading complication after cataract surgery, and is mainly induced by the proliferation and migration of residual lens epithelial cells (LECs). Although numerous attempts have been made to reduce the incidence of PCO, this complication remains a critical challenge in postoperative visual recovery. This study aims to report a functionalized intraocular...
The development of high‐efficiency enzyme mimics is of great significance in the field of biocatalysis. However, it remains challenging to design novel enzyme mimics with multiple enzyme‐like activities, excellent stability, and good reusability. Herein, a facile molecular assembly strategy to construct dialdehyde cellulose (DAC) templated Cu‐doped polydopamine (DAC@PDA/Cu) membrane with dual enzyme‐like...
Design and development of highly efficient photocatalytic materials are key to employ photocatalytic technology as a sound solution to energy and environment related challenges. This work aims to significantly boost photocatalytic activity through rich indium vacancies (VIn) In2S3 with atomic p–n homojunction through a one‐pot preparation strategy. Positron annihilation spectroscopy and electron paramagnetic...
Exploring highly active and cost‐efficient single‐atom catalysts (SACs) for oxygen reduction reaction (ORR) is critical for the large‐scale application of Zn–air battery. Herein, density functional theory (DFT) calculations predict that the intrinsic ORR activity of the active metal of SACs follows the trend of Co > Fe > Ni ≈ Cu, in which Co SACs possess the best ORR activity due to its optimized...
In spite of the widespread application of vaccine adjuvants in various preventive vaccines at present, the existing adjuvants are still hindered by weak cellular immunity responses in therapeutic cancer vaccines. Herein, a hollow silica nanoadjuvant containing aluminum hydroxide spikes on the surface (SiAl) is synthesized for the co‐loading of chemotherapeutic drug doxorubicin (Dox) and tumor fragment...
The slow kinetics and poor structural stability prevent transition metal selenides from being widely used in sodium‐ion batteries (SIBs) and potassium‐ion batteries (PIBs). Herein, the “flower‐like” porous carbon anchored by Zn‐Mn binary selenides (ZMS@FC) composites are fabricated by selenizing the modified hierarchically metal‐organic frameworks. The 2D conductive hierarchically flakes’ abundant...

The endoplasmic reticulum (ER) plays an important role in protein synthesis, processing and secretion. ER‐targeting phototherapy significantly amplifies ER stress, promotes tumor antigen release, and elicits a robust immunogenic cell death. In article number 2202728 by Weidong Wang, Junping Wang, Shenglin Luo, and co‐workers, a small molecular heptamethine cyanine photosensitizer...
In organic electronics, local crystalline order is of critical importance for the charge transport. Grain boundaries between molecularly ordered domains are generally known to hamper or completely suppress charge transfer and detailed knowledge of the local electronic nature is critical for future minimization of such malicious defects. However, grain boundaries are typically hidden within the bulk...
Severe inflammation and myogenic differentiation disorder are the major obstacles to skeletal muscle healing after injury. MicroRNAs (miRNAs) play an important role as regulatory molecules during the process of muscle healing, but the detailed mechanism of miRNA‐mediated intercellular communication between myoblasts and macrophages remains unclear. Here, it is reported that myoblasts secrete miRNAs‐enriched...
The emerging applications of hydrogel materials at different length scales, in areas ranging from sustainability to health, have driven the progress in the design and manufacturing of microgels.
