Solution‐processed photodetectors have emerged as promising candidates for next‐generation of visible‐near infrared (vis–NIR) photodetectors. This is attributed to their ease of processing, compatibility with flexible substrates, and the ability to tune their detection properties by integrating complementary photoresponsive semiconductors. However, the limited performance continues to hinder their...
Porous frameworks that display dynamic responsiveness are of interest in the fields of smart materials, information technology, etc. In this work, a novel copper‐based dynamic metal‐organic framework [Cu3TTBPE6(H2O)2] (H4TTBPE = 1,1,2,2‐tetrakis(4″‐(1H‐tetrazol‐5‐yl)‐[1,1″‐biphenyl]‐4‐yl)ethane), denoted as HNU‐1, is reported which exhibits modulable photoelectromagnetic properties. Due to the synergetic...
Efficient construction of proton transport channels in proton exchange membranes maintaining conductivity under varied humidity is critical for the development of fuel cells. Covalent organic frameworks (COFs) hold great potential in providing precise and fast ion transport channels. However, the preparation of continuous free‐standing COF membranes retaining their inherent structural advantages to...
Metal nanoclusters with precisely modulated structures at the nanoscale give us the opportunity to synthesize and investigate 1D nanomaterials at the atomic level. Herein, it realizes selective 1D growth of building block nanocluster “Au13Cd2” into three structurally different nanoclusters: “hand‐in‐hand” (Au13Cd2)2O, “head‐to‐head” Au25, and “shoulder‐to‐shoulder” Au33. Detailed studies further reveals...
Biofilm is a spatially organized community formed by the accumulation of both microorganisms and their secretions, leading to persistent and chronic infections because of high resistance toward conventional antibiotics. In view of the tunable physicochemical properties and the related unique biological behavior (e.g., size‐, shape‐, and surface charge‐dependent penetration, protein corona endowed...
Strain gradients widely exist in development and physiological activities. The directional movement of cells is essential for proper cell localization, and directional cell migration in responses to gradients of chemicals, rigidity, density, and topography of extracellular matrices have been well‐established. However; it is unclear whether strain gradients imposed on cells are sufficient to drive...
Covalent organic frameworks (COFs) with precisely controllable structures and highly ordered porosity possess great potential as electrocatalysts for hydrogen evolution reaction (HER). However, the catalytic performance of pristine COFs is limited by the poor active sites and low electron transfer. Herein, to address these issues, the conductive carbon nanotubes (CNTs) are coated by a defined structure...
The ability to effectively treat deep bacterial infections while promoting osteogenesis is the biggest treatment demand for diseases such as osteomyelitis. Microwave therapy is widely studied due to its remarkable ability to penetrate deep tissue. This paper focuses on the development of a microwave‐responsive system, namely, a zinc ion (Zn2+) doped graphite carbon nitride (CN) system (BZCN), achieved...
Electrocatalysts based on Fe and other transition metals are regarded as most promising candidates for accelerating the oxygen evolution reaction (OER), whereas whether Fe is the catalytic active site for OER is still under debate. Here, unary Fe‐ and binary FeNi‐ based catalysts, FeOOH and FeNi(OH)x, are produced by self‐reconstruction. The former is a dual‐phased FeOOH, possessing abundant oxygen...
The current immunotherapy strategies for triple negative breast cancer (TNBC) are greatly limited due to the immunosuppressive tumor microenvironment (TME). Immunization with cancer vaccines composed of tumor cell lysates (TCL) can induce an effective antitumor immune response. However, this approach also has the disadvantages of inefficient antigen delivery to the tumor tissues and the limited immune...
The additive engineering strategy promotes the efficiency of solution‐processed perovskite solar cells (PSCs) over 25%. However, compositional heterogeneity and structural disorders occur in perovskite films with the addition of specific additives, making it imperative to understand the detrimental impact of additives on film quality and device performance. In this work, the double‐edged sword effects...
Recent studies have found that the existence of oxygen around the active sites may be essential for efficient electrochemical CO2‐to‐CO conversion. Hence, this work proposes the modulation of oxygen coordination and investigates the as‐induced catalytic behavior in CO2RR. It designs and synthesizes conjugated phthalocyanine frameworks catalysts (CPF‐Co) with abundant CoN4 centers as an active source,...
Rare earth‐doped metal oxide nanocrystals have a high potential in display, lighting, and bio‐imaging, owing to their excellent emission efficiency, superior chemical, and thermal stability. However, the photoluminescence quantum yields (PLQYs) of rare earth‐doped metal oxide nanocrystals have been reported to be much lower than those of the corresponding bulk phosphors, group II‐VI, and halide‐based...

In article numbered 2207936, Man‐Bo Li, Yan Zhao, Zhikun Wu, and co‐workers synthesize a novel atomically precise Au14 nanoclusterzyme, which can activate O2 to O2•− under visible light and leads to the blue color of 3,3′,5,5′‐tetramethylbenzidine (TMB). With the addition of acetylcholinesterase (AChE), the blue color of (Au14 + TMB) solution disappears, but the further addition of...
The hollow sandwich core–shell micro‐nanomaterials are widely used in materials, chemistry, and medicine, but their fabrication, particularly for transition metal phosphides (TMPs), remains a great challenge. Herein, a general synthesis strategy is presented for binary TMPs hollow sandwich heterostructures with vertically interconnected nanosheets on the inside and outside surfaces of polyhedron FeCoP...
