Efficient transceivers and antennas at terahertz frequencies are leading the development of 6G terahertz communication systems. The antenna design for high‐resolution terahertz spatial sensing and communication remains challenging, while emergent metallic metasurface antennas can address this issue but often suffer from low efficiency and complex manufacturing. Here, an all‐dielectric integrated meta‐antenna...
Herein, the vitamin K2 (VK2)/maleimide (MA) coloaded mesoporous silica nanoparticles (MSNs), functional molecules including folic acid (FA)/triphenylphosphine (TPP)/tetrapotassium hexacyanoferrate trihydrate (THT), as well as CaCO3 are explored to fabricate a core‐shell‐corona nanoparticle (VMMFTTC) for on‐demand anti‐tumor immunotherapy. After application, the tumor‐specific acidic environment first...
Conductive elastomers are extensively used in electronics; however, they are prone to mechanical damage, have shortened service life, and cause environmental pollution and resource waste under the influence of external factors. Therefore, conductive elastomers with rapid self‐healing properties are crucial for solving these problems. To that end, a conductive elastomer based on a polymerizable deep...
Covalent organic frameworks (COFs) offer a desirable platform to explore multichoromophoric arrays for photocatalytic conversion. Symmetric arrangement of choromophoric modules over π‐extended frameworks enhances exciton delocalization while impairing excitation density and accordingly photochemical reactivity. Herein, a photoisomerization‐driven strategy is proposed to break the excited‐state symmetry...
Designing reliable and energy‐efficient memristors for artificial synaptic arrays in neuromorphic computing beyond von Neumann architecture remains a challenge. Here, memristors based on emerging layered nickel phosphorus trisulfide (NiPS3) are reported that exhibit several favorable characteristics, including uniform bipolar nonvolatile switching with small operating voltage (<1 V), fast switching...
Prelithiation is an essential technology to compensate for the initial lithium loss of lithium‐ion batteries due to the formation of solid electrolyte interphase (SEI) and irreversible structure change. However, the prelithiated materials/electrodes become more reactive with air and electrolyte resulting in unwanted side reactions and contaminations, which makes it difficult for the practical application...
To cater to the swift advance of flexible wearable electronics, there is growing demand for flexible energy storage system (ESS). Aqueous zinc ion energy storage systems (AZIESSs), characterizing safety and low cost, are competitive candidates for flexible energy storage. Hydrogels, as quasi‐solid substances, are the appropriate and burgeoning electrolytes that enable high‐performance flexible AZIESSs...
Metal single‐atom catalysts are promising in electrochemical CO2 reduction reaction (CO2RR). The pores and cavities of the supports can promote the exposure of active sites and mass transfer of reactants, hence improve their performance. Here, iron oxalate is added to ZIF‐8 and subsequently form hollow carbon nanocages during calcination. The formation mechanism of the hollow structure is studied...
Optimizing catalysts for competitive photocatalytic reactions demand individually tailored band structure as well as intertwined interactions of light absorption, reaction activity, mass, and charge transport. Here, a nanoparticulate host–guest structure is rationally designed that can exclusively fulfil and ideally control the aforestated uncompromising requisites for catalytic reactions. The all‐inclusive...
In this paper, Au@Ag nanopencil is designed as a multimodality plasmonic nanoprobe based on asymmetric etching for the detection of SCN− and ClO−. Au@Ag nanopencil with Au tip and Au@Ag rod is prepared by asymmetric tailoring of uniformly grown silver‐covered gold nanopyramids under the combined effect of partial galvanic replacement and redox reaction. By asymmetric etching in different systems,...
Porous metal–organic framework (MOF) liquids with permanent porosity, good fluidity, and fine dispersion attract broad attention in catalysis, transportation, gas storage, and chemical separations. Yet, the design and synthesis of porous MOF liquids for drug delivery remain less explored. Herein, a simple and general strategy is reported to prepare ZIF‐91 porous liquid (ZIF‐91‐PL) via surface modification...
Solid electrolyte interphase (SEI) plays an important role in regulating the interfacial ion transfer and safety of Lithium‐ion batteries (LIBs). It is unstable and readily decomposed releasing much heat and gases and thus triggering thermal runaway. Herein, in situ heating X‐ray photoelectron spectroscopy is applied to uncover the inherent thermal decomposition process of the SEI. The evolution of...
Uncontrollable dendrite growth and sluggish ion‐transport kinetics are considered as the main obstacles for the further development of high‐performance aqueous zinc ion batteries (AZIBs). Here, a nature‐inspired separator (ZnHAP/BC) is developed to tackle these issues via the hybridization of the biomass‐derived bacterial cellulose (BC) network and nano‐hydroxyapatite particles (HAP). The as‐prepared...
Manipulations of singlet oxygen (1O2) generations by the integration of both aggregation‐induced emission luminogen (AIEgen) photosensitizer and photochromic moieties have diversified features in photodynamic therapy applications.

Oxygen Evolution and Reduction Reactions
The spin effects in oxygen evolution/reduction reaction, and advances in design, characterization and mechanisms of spin catalyst are highlighted in article number 2205638 by Hongchao Liu, Hui Pan, and co‐workers. The factors that affect spin are also discussed in detail. Some general rules are obtained, and perspectives on the study of spin catalysts are given...
Searching for high effective catalysts has been an endless effort to improve the efficiency of green energy harvesting and degradation of pollutants. In the past decades, tremendous strategies are explored to achieve high effective catalysts, and various theoretical understandings are proposed for the improved activity. As the catalytic reaction occurs at the surface or edge, the unsaturated ions...
Molecular catalysts have been receiving increasingly attention in the electrochemical CO2 reduction reaction (CO2RR) with attractive features such as precise catalytic sites and tunable ligands. However, the insufficient activity and low selectivity of deep reduction products restrain the utilization of molecular catalysts in CO2RR.

MRSA Phototherapy
In article number 2203292, Weiliang Xia, Yingzheng Zhao, Yijie Chen, and co‐workers show that Van‐Lipo(IR780)‐PFC (an oxygen‐carrying perfluorocarbon nanoemulsion stabilized by a vancomycin‐functionalized sphingo‐myelin liposome loaded with IR780) can capture methicillin‐resistant Staphylococcus aureus (MRSA) toxins in situ, resulting in the on‐demand release of phototherapeutic...
An effective therapeutic strategy against methicillin‐resistant Staphylococcus aureus (MRSA) that does not promote further drug resistance is highly desirable. While phototherapies have demonstrated considerable promise, their application toward bacterial infections can be limited by negative off‐target effects to healthy cells. Here, a smart targeted nanoformulation consisting of a liquid perfluorocarbon...
