The solution‐processed zinc oxide (ZnO) electron transport layer (ETL) always exhibits ubiquitous defects, and its photocatalytic activity is detrimental for the organic solar cell (OSC) to achieve high efficiency and stability. Herein, an organic dye molecule, PDINN‐S is introduced, to dope ZnO, constructing a hybrid ZnO:PDINN‐S ETL. This hybrid ETL exhibits improved electron mobility and conductivity,...
Acidic residues (Asp and Glu) have a high prevalence on protein surfaces, but cross‐linking reactions targeting these residues are limited. Existing methods either require high‐concentration coupling reagents or have low structural compatibility. Here a previously reported “plant‐and‐cast” strategy is extended to develop heterobifunctional cross‐linkers. These cross‐linkers first react rapidly with...
Non‐aqueous solvents, in particular N,N‐dimethylaniline (NMP), are widely applied for electrode fabrication since most sodium layered oxide cathode materials are readily damaged by water molecules. However, the expensive price and poisonousness of NMP unquestionably increase the cost of preparation and post‐processing. Therefore, developing an intrinsically stable cathode material that can implement...
Diabetic alveolar bone defect (DABD) causes persistent bacterial infection, prolonged inflammation, and delayed bone healing, making it a considerable clinical challenge. In this study, by integrating silver nanoclusters (AgNCs) and M2 macrophage‐derived extracellular vesicles (M2EVs), a multifunctional DNA‐based hydrogel, called Agevgel, is developed with antibacterial, anti‐inflammatory, immunomodulatory,...
As the most popular liquid metal (LM), gallium (Ga) and its alloys are emerging as functional materials due to their unique combination of fluidic and metallic properties near room temperature. As an important branch of utilizing LMs, micro‐ and submicron‐particles of Ga‐based LM are widely employed in wearable electronics, catalysis, energy, and biomedicine. Meanwhile, the phase transition is crucial...
Microbial Fuel Cells
In article number 2304754, Jianmeng Chen, Shihan Zhang, Jingkai Zhao, and co‐workers provide a pore‐matched strategy to develop an excellent bioanode to boost electron extraction in microbial fuel cells. Due to the suitable pore size range of the sponge‐like electrode matching with microbial cells, the microbial cells can be attached individually and wired with the abiotic substrate...
Polymer Vesicles
In article number 2306219, Daniela A. Wilson and co‐workers report the programmable engineering of compartment networks achieved through the stress‐dependent deformation of polymer vesicles. Polymer vesicles can be transformed through either a tubulation pathway by applying mild osmotic stress or through a deflation pathway by applying an osmotic shock. The stress dependency enables...
Nanocontainers that can sense and respond to environmental stimuli like cells are desirable for next‐generation delivery systems. However, it is still a grand challenge for synthetic nanocontainers to mimic or even surpass the shape adaption of cells, which may produce novel compartments for cargo loading. Here, this work reports the engineering of compartment network with a single polymer vesicle...
Microbial fuel cells (MFCs) are of great potential for wastewater remediation and chemical energy recovery. Nevertheless, limited by inefficient electron transfer between microorganisms and electrode, the remediation capacity and output power density of MFCs are still far away from the demand of practical application. Herein, a pore‐matching strategy is reported to develop uniform electroactive biofilms...
MXenes are considered a promising negative electrode material for potassium ion batteries (PIBs) in view of their low potassium ion diffusion barrier and excellent electrical conductivity. However, the stacking phenomenon in practical applications severely reduces their active surface and leads to slow K+ diffusion. Herein, a facile composite template method is proposed to construct stacking‐resistance...
Bismuth (Bi) has attracted attention as a promising anode for sodium‐ion batteries (SIBs) owing to its suitable potential and high theoretical capacity.

For comparison, a random linear copolymer, PR2 is also synthesized based on the...
Developing novel synthetic strategies to downsize metal‐organic frameworks (MOFs) from polydisperse crystals to monodisperse nanoparticles is of great importance for their potential bioapplications.

Herein, the synthesis of an efficient ORR electrocatalyst that is composed...
Tendon stem/progenitor cells (TSPCs) therapy is a promising strategy for enhancing cell matrix and collagen synthesis, and regulating the metabolism of the tendon microenvironment during tendon injury repair. Nevertheless, the barren microenvironment and gliding shear of tendon cause insufficient nutrition supply, damage, and aggregation of injected TSPCs around tendon tissues, which severely hinders...
