Multifunction superhydrophobic coatings that facilitate water harvesting are attractive for addressing the daunting water crisis, yet, they are caught in a double bind when their durability is considered, as durable coatings will require both tough micro‐textures to survive concentrated stress and high‐surface‐energy chemistry to form chemical bonds within the matrix. To date, a universal bulk‐phase...
Superhydrophobic Coatings
In article number 2307561, Youfa Zhang and co‐workers develop a binary cooperative cell design that eliminates the mutual exclusion between the features of functions and mechanical stability of superhydrophobic coatings. The coating is structurally strong and exhibits almost all aspects of enhancement including ultra‐durability and over 1000% enhancement in water harvesting...
The contrast agents and tumor treatments currently used in clinical practice are far from satisfactory, due to the specificity of the tumor microenvironment (TME). Identification of diagnostic and therapeutic reagents with strong contrast and therapeutic effect remains a great challenge. Herein, a novel carbon dot nanozyme (Mn‐CD) is synthesized for the first time using toluidine blue (TB) and manganese...
Defect‐rich carbon materials are considered as one of the most promising anodes for potassium‐ion batteries due to their enormous adsorption sites of K+, while the realization of both rate capability and cycling stability is still greatly limited by unstable electrochemical kinetics and inevitable structure degradation. Herein, an Fe3+‐induced hydrothermal‐pyrolysis strategy is reported to construct...
Lithium metal batteries (LMBs) are the most promising high energy density energy storage technologies for electric vehicles, military, and aerospace applications. LMBs require further improvement to operate efficiently when chronically or routinely exposed to high temperatures. Electrolyte engineering with high temperature tolerance and electrode compatibility has been essential to the development...
There is an urgent demand of ultrathin high‐performance microwave absorbing materials (MAMs) in the electromagnetic protection field. However, minimizing thickness is challenging mainly due to dielectric mismatch at high permittivity from excessive dielectric loss, leading to strong reflection at 2–18 GHz. Here, a hybrid TaS2/Co(Cp)2 superlattice is fabricated with alternating [TaS2] inorganic layers...
Pore space partition (PSP) is an effective materials design method for developing high‐performance small‐pore materials for storage and separation of gas molecules. The continued success of PSP depends on broad availability and judicious choice of pore‐partition ligands and better understanding of each structural module on stability and sorption properties. Here, by using substructural bioisosteric...
Coupling the photoproduction of solar fuel and value‐added chemicals is highly attractive, as it maximizes the utilization of incident sunlight and the economic value of photocatalytic reactions. Constructing intimate semiconductor heterojunction for these reactions is highly desirable due to accelerated charge separation at the interfacial contact, but is challenged by material synthesis. Here, an...
Polymeric Nanoparticles
In article number 2300801, Liang‐Yin Chu, Wei Wang, and co‐workers develop a spontaneous confined nanoemulsification strategy to facilely fabricate sub‐10 nm uniform polymeric nanoparticles by template synthesis of nanoemulsions. The strategy employs a self‐confined reaction with highly accumulated surfactants in chemically‐active droplets to achieve enhanced molecular‐level...
Sub‐10 nm nanoparticles are known to exhibit extraordinary size‐dependent properties for wide applications. Many approaches have been developed for synthesizing sub‐10 nm inorganic nanoparticles, but the fabrication of sub‐10 nm polymeric nanoparticles is still challenging. Here, a scalable, spontaneous confined nanoemulsification strategy that produces uniform sub‐10 nm nanodroplets for template...
The low electrical conductivity and the high surface defect density of the TiO2 electron transport layer (ETL) limit the power conversion efficiency (PCE) of corresponding perovskite solar cells (PSCs). Here, the conductivity and defect modulation of the mesoporous TiO2 (mp‐TiO2) ETL via oxygen vacancy (OV) management by the reduction and oxidation treatment are reported. Reduction treatment via reducing...
Despite the unprecedented progress in lead‐based perovskite solar cells (PSCs), the toxicity and leakage of lead from degraded PSCs triggered by deep‐level defects and poor crystallization quality increase environmental risk and become a critical challenge for eco‐friendly PSCs. Here, a novel 2D polyoxometalate (POM)‐based metal–organic framework (MOF) (C5NH5)4(C3N2H5)2Zn3(H8P4Mo6O31)2·2H2O (POMOF)...
Surface open polar sites within the voids of porous molecular crystals define the localized physicochemical environment for critical functions such as gas separation and molecular recognition. This study presents a new charge‐assisted hydrogen bonding (H‐bonding) motif, by exploiting inorganic ammonium (NH4+) cations as H‐bond donors, to regulate the assembly of C2‐symmetric carboxylic tectons for...
Developing efficient heterojunction electrocatalysts and uncovering their atomic‐level interfacial mechanism in promoting sulfur‐species adsorption‐electrocatalysis are interesting yet challenging in lithium‐sulfur batteries (LSBs).

Nanopore brings extraordinary properties for a variety of potential applications in various industrial sectors. Since manufacturing of solid‐state nanopore is first reported in 2001, solid‐state nanopore has become a hot topic in the recent years. An increasing number of manufacturing methods have been reported, with continuously decreased sizes from hundreds of nanometers at the beginning to ≈1 nm...
Nanodrugs are becoming increasingly important in the treatment of bacterial infection, but their low penetration ability to bacterial biofilm is still the main challenge hindering their therapeutic effect. Herein, nitric oxide (NO)‐driven nanomotor based on L‐arginine (L‐Arg) and gold nanoparticles (AuNPs) loaded dendritic mesoporous silica nanoparticles (AG‐DMSNs) is fabricated. AG‐DMSNs have the...
The tremendous volume change and severe pulverization of micro‐sized Sb anode generate no stable capacity in potassium‐ion batteries (PIBs).

Here, a green, scalable template‐free method for designing...
Rechargeable aluminum batteries (RABs) have been paid considerable attention in the field of electrochemical energy storage batteries due to their advantages of low cost, good safety, high capacity, long cycle life, and good wide‐temperature performance.

Anode‐supported protonic ceramic fuel cells (PCFCs) are highly promising and efficient energy conversion systems.
