Highly active bifunctional electrocatalysts for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) have always been the key factors to affect the performance of zinc–air batteries. However, integrating the independent reaction sites of ORR and OER in a catalyst remains a major challenge. Herein, a collaborative strategy based on defect induction and doping is proposed to prepare the...
Both the uncoordinated Pb2+ and excess PbI2 in perovskite film will create defects and perturb carrier collection, thus leading to the open‐circuit voltage (VOC) loss and inducing rapid performance degradation of perovskite solar cells (PSCs). Herein, an additive of 3‐aminothiophene‐2‐carboxamide (3‐AzTca) that contains amide and amino and features a large molecular size is introduced to improve the...
The phototheranostics in the second near‐infrared window (NIR‐II) have proven to be promising for the precise cancer theranostics. However, the non‐responsive and “always on” imaging mode lacks the selectivity, leading to the poor diagnosis specificity. Herein, a tumor microenvironment (TME) activated NIR‐II phototheranostic nanoplatform (Ag2S‐Fe(III)‐DBZ Pdots, AFD NPs) is designed based on the principle...
The establishment of effective antitumor immune responses of vaccines is mainly limited by insufficient priming tumor infiltration of T cells and immunosuppressive tumor microenvironment (TME). Targeting β‐adrenergic receptor (β‐AR) signaling exerts promising benefits on reversing the suppressive effects directly on T cells, but it appears to have considerably limited antitumor performance when combined...
Sodium‐based dual‐ion batteries (SDIBs) have become a new type of energy storage device with great application value because of their high operating voltage, high energy density, and low cost. However, transition‐metal dichalcogenide (TMD) anodes show unsatisfactory Na+ electrochemical performance owing to the low intrinsic conductivity and inferior ion transport kinetics. Here, an elaborate design...
Rechargeable magnesium batteries (RMBs) are promising candidates to replace currently commercialized lithium‐ion batteries (LIBs) in large‐scale energy storage applications owing to their merits of abundant resources, low cost, high theoretical volumetric capacity, etc. However, the development of RMBs is still facing great challenges including the incompatibility of the electrolyte and the lack of...
Polyhedral oligomeric silsesquioxane (POSS) is a family of organic/inorganic hybrid materials with specific molecular symmetry, and shows great potential in the structural design of nanomaterials. Here, a “bottom‐up” strategy is designed to fabricate 3D interconnected Si/SiOx/C nanorings (NRs) via AlCl3‐assisted aluminothermic reduction using dodecaphenyl cage silsesquioxane (T12‐Ph) as the building...
Owing to the low cost of sodium/potassium resources and similar electrochemical properties of Na+/K+ to Li+, sodium‐ion batteries (SIBs) and potassium‐ion batteries (KIBs) are regarded as promising alternatives to lithium‐ion batteries (LIBs) in large‐scale energy storage field. However, traditional organic liquid electrolytes bestow SIBs/KIBs with serious safety concerns. In contrast, quasi‐/solid‐phase...

Amplifying the chemotherapy‐driven immunogenic cell death (ICD) for efficient and safe cancer chemoimmunotherapy remains a challenge. Here, a potential ICD nanoamplifier containing diselenide‐bridged mesoporous organosilica nanoparticles (MONs) and chemotherapeutic ruthenium compound (KP1339) to achieve cancer chemoimmunotherapy is tailored. KP1339‐loaded MONs show controlled drug release profiles...
The effectiveness of active targeting in cancer nanomedicine is becoming increasingly more debatable. Here, the role of the ligand functionalization patterns (number and distribution) on nanoparticle surfaces in tumor targeting is investigated using a 9 nm sized miniferritin protein nanocage, Dps modified with Arg‐Gly‐Asp (RGD) ligands whose functionalization patterns are precisely controlled. In...
The rapid development of lightweight and wearable devices requires electronic circuits possessing compact, high‐efficiency, and long lifetime in very limited space. Alternating current (AC) line filters are usually tools for manipulating the surplus AC ripples for the operation of most common electronic devices. So far, only aluminum electrolytic capacitors (AECs) can be utilized for this target....
The feasibility of transition metal carbides (TMCs) as promising high‐rate electrodes is still hindered by low specific capacity and sluggish charge transfer kinetics. Improving charge transport kinetics motivates research toward directions that would rely on heterostructures. In particular, heterocomposing with carbon‐rich TMCs is highly promising for enhancing Li storage. However, due to limited...
To address demands for increased data transmission rates, electrically small antennas (ESAs) that simultaneously offer large frequency bandwidths and small physical sizes are of growing interest. 3D layouts are particularly important in this context and among various 3D ESAs, systems that adopt hemispherical shapes are very promising, because they can occupy the entire Chu‐sphere and offer outstanding...
Carbon materials have attracted considerable attention as anodes for lithium‐ion and sodium‐ion batteries due to their low cost and environmental friendliness. This work reports an advanced carbon nanostructure that takes advantage of the chelation effect of glucose and metal ions, which ensures the uniform dispersion of metal in the precursor. Thus, an effective catalytic conversion from sp3 to sp...
Organic–inorganic lead halide perovskite solar cells (PVSCs), as a competing technology with traditional inorganic solar cells, have now realized a high power conversion efficiency (PCE) of 22.1%. In PVSCs, interfacial carrier recombination is one of the dominant energy‐loss mechanisms, which also results in the simultaneous loss of potential efficiency. In this work, for planar inverted PVSCs, the...

The dual‐ion battery (DIB) system has attracted great attention owing to its merits of low cost, high energy, and environmental friendliness. However, the DIBs based on sodium‐ion electrolytes are seldom reported due to the lack of appropriate anode materials for reversible Na+ insertion/extraction.
