The development of excellently stretchable, highly mobile, and sustainable power supplies is of great importance for self‐power wearable electronics. Transpiration‐driven hydrovoltaic power generator (HPG) has been demonstrated to be a promising energy harvesting strategy with the advantages of negative heat and zero‐carbon emissions. Herein, this work demonstrates a fiber‐based stretchable HPG with...
High‐entropy oxides (HEOs) have emerged as promising anode materials for next‐generation lithium‐ion batteries (LIBs). Among them, spinel HEOs with vacant lattice sites allowing for lithium insertion and diffusion seem particularly attractive. In this work, electrospun oxygen‐deficient (Mn,Fe,Co,Ni,Zn) HEO nanofibers are produced under environmentally friendly calcination conditions and evaluated...
The threshold voltage (Vth) adjustment of complementary metal‐oxide‐semiconductor (CMOS) thin film transistors (TFTs) is one of the research hotspots due to its key role in energy consumption control of CMOS circuits. Here, ultralow‐power flexible CMOS circuits based on well‐matched enhancement‐mode (E‐mode) CMOS single‐walled carbon nanotube (SWCNT) TFTs are successfully achieved through tuning the...
Developing bifunctional catalysts for oxygen electrochemical reactions is essential for high‐performance electrochemical energy devices. Here, a Mott–Schottky heterojunction composed of porous cobalt–nitrogen–carbon (Co‐N‐C) polyhedra containing abundant metal‐phosphides for reversible oxygen electrocatalysis is reported. As a demonstration, this catalyst shows excellent activity in the oxygen electrocatalysis...
The rapid progress of information technology is accompanied by plenty of information embezzlement and forgery, but developing advanced encryption technologies to ensure information security remains challenging. Phase separation commonly leads to a dramatic change in the transmittance of hydrophilic polymer networks, which is a potential method for information security but is often neglected. Here,...
Metal‐oxo clusters have emerged as advanced proton conductors with well‐defined and tunable structures. Nevertheless, the exploitation of metal‐oxo clusters with high and stable proton conductivity over a relatively wide temperature range still remains a great challenge. Herein, three sulfate groups decorated zirconium‐oxo clusters (Zr6, Zr18, and Zr70) as proton conductors are reported, which exhibit...
Hollow Core‐Shell Structures
Core‐shell Cu2‐xS@ZnIn2S4 hollow nanoboxes S‐scheme heterojunction photocatalysts are prepared via surface growth deposition and hydrothermal method. The Cu2‐xS@ZnIn2S4 photocatalyst exhibits excellent photothermal‐photocatalytic performance. This can be attributed to core‐shell S‐scheme heterojunction promoting efficient interfacial contact and facilitating the spatial...
Major issues in photocatalysis include improving charge carrier separation efficiency at the interface of semiconductor photocatalysts and rationally developing efficient hierarchical heterostructures. Surface continuous growth deposition is used to make hollow Cu2‐xS nanoboxes, and then simple hydrothermal reaction is used to make core‐shell Cu2‐xS@ZnIn2S4 S‐scheme heterojunctions. The photothermal...
Solid‐state lithium metal batteries (SSLMBs) promise high energy density and high safety by employing high‐capacity Li metal anode and solid‐state electrolytes. However, the construction of the composite Li metal electrode is a neglected but important subject when the extensive research focuses on the interface between the solid electrolyte Li6.4La3Zr1.4Ta0.6O12 and Li metal anode. Here, an electronic–ionic...
Bifunctional Catalysts
In article number 2201974, Yunqi Liu, Xuan Yang, Xiang Feng, Yuan Pan, and co‐workers propose an encapsulation‐adsorption‐pyrolysis strategy for constructing Co‐Te diatomic sites with special CoN3C1‐TeN1C3 coordination structure anchored in N‐doped carbon, as efficient bifunctional catalysts for synergistic electrocatalytic hydrogen evolution and oxygen reduction. This work...
A encapsulation–adsorption–pyrolysis strategy for the construction of atomically dispersed Co‐Te diatomic sites (DASs) that are anchored in N‐doped carbon is reported as an efficient bifunctional catalyst for electrocatalytic hydrogen evolution reaction (HER) and oxygen reduction reaction (ORR). The as‐constructed catalyst shows the stable CoN3C1‐TeN1C3 coordination structure before and after HER...
Metallic zinc is regarded as an ideal anode material for high‐energy aqueous zinc ion batteries owing to its high theoretical capacity, low cost, and abundant resource. However, the undesirable dendrite formation and side reactions occurring on Zn anode during the long‐term cycling process seriously restrict the electrochemical performance of the device. Herein, 1‐hydroxy ethylidene‐1,1‐diphosphonic...
All‐in‐One Theranostics
In article number 2104660, Xin Jia, Bo Han, and co‐workers coordinate bismuth ions and natural polyphenols into a metal phenolic network (MPN). Tetracycline is used as a model drug to evaluate the efficacy and drug carrying capacity of the MPN. The results show that the drug delivery system constructed in this work provides a versatile intragastric‐targeting all‐in‐one theranostic...
Bismuth‐containing therapies are suggested as first‐line and rescue alternatives for gastric ulcer (GU) treatment and Helicobacter pylori eradication. The current treatment strategy is called quadruple therapy and includes proton pump inhibitors, bismuth, and two broad‐band antibiotics. This fact may affect medication compliance, leading to a resistance rate of more than 25% to clarithromycin or metronidazole...
The intrinsic properties of carbon‐based material and the voltage window of electrolyte are the two key barriers to restrict the energy density of carbon‐based supercapacitors (SCs). Herein, a cucurbit[6]uril‐derived nitrogen‐doped hierarchical porous carbon (CBCx) with unique pore structure characteristics is synthesized and successfully applied to construct SCs based on different electrolyte systems...
Artificial muscles are reported in which reduced graphene oxide (rGO) is trapped in the helical corridors of a carbon nanotube (CNT) yarn. When electrochemically driven in aqueous electrolytes, these coiled CNT/rGO yarn muscles can contract by 8.1%, which is over six times that of the previous results for CNT yarn muscles driven in an inorganic electrolyte (1.3%). They can contract to provide a final...
