Despite the intriguing potential, nano‐socketed Cu/perovskite heterostructures for CO2 electroreduction (CO2RR) are still in their infancy and rational optimization of their CO2RR properties is lacking. Here, an effective strategy is reported to promote CO2‐to‐C2+ conversion over nano‐socketed Cu/perovskite heterostructures by A‐site‐valence‐controlled oxygen vacancies. For the proof‐of‐concept catalysts...
Crystal phase engineering has emerged as a powerful tool for tailoring the electrocatalytic performance, yet its impact on nitrate reduction to ammonia (NRA) remains largely uncharted territory. Herein, density functional theory (DFT) calculations are performed to unravel the influence of the crystal phase of FeOOH on the adsorption behavior of *NO3. Inspiringly, FeOOH samples with four distinct crystal...
Boosting the hydrogen evolution reaction (HER) activity of α‐MoB2 at large current densities and in pH‐universal medium is significant for efficient hydrogen production. In this work, Co2B/MoB2 heterostructured nanoclusters are prepared by molten‐salt electrolysis (MSE) and then used as a HER catalyst. The composition, structure, and morphology of Co2B/MoB2 can be modulated by altering the stoichiometries...
Hybrid organic–inorganic perovskite (HOIP) ferroelectric materials have great potential for developing self‐powered electronic transducers owing to their impressive piezoelectric performance, structural tunability and low processing temperatures. Nevertheless, their inherent brittle and low elastic moduli limit their application in electromechanical conversion. Integration of HOIP ferroelectrics and...
Surface defects in tin‐based perovskite films disrupt the periodic arrangement of atoms in crystals, making surface atoms more susceptible to interactions with water and oxygen molecules in the surrounding environment. The diffusion of oxygen ions into the perovskite interior leads to the formation of severe bulk defects, which compromises the performance of tin‐based perovskite solar cells (PSCs)...
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...
Bacteria‐induced epidemics and infectious diseases are seriously threatening the health of people around the world. In addition, antibiotic therapy has been inducing increasingly more serious bacterial resistance, which makes it urgent to develop new treatment strategies to combat bacteria, including multidrug‐resistant bacteria. Natural extracts displaying antibacterial activity and good biocompatibility...
Radium‐223 (223Ra) is the first‐in‐class alpha‐emitter to mediate tumor eradication, which is commonly thought to kill tumor cells by directly cleaving double‐strand DNA. However, the immunogenic characteristics and cell death modalities triggered by 223Ra remain unclear. Here, it is reported that the 223Ra irradiation induces the pro‐inflammatory damage‐associated molecular patterns including calreticulin,...
That magic‐size clusters (MSCs) have their counterpart precursor compounds (PCs) has not been generally accepted by expertise circles. Here, experimental evidence to support this new concept is presented. With aqueous‐phase CdSe MSCs as a model system, it is shown that when the MSCs are dispersed in water containing a certain amount of L‐cysteine (Cys), the MSCs disappear slowly. Upon the addition...
The unsatisfactory power conversion efficiency (PCE) and long‐term stability of tin perovskite solar cells (TPSCs) restrict its further development as alternatives to lead perovskite solar cells (LPSCs). Considerable research has focused on the negative impacts of O2 and H2O, while discussions about degradation mechanism in an inert atmosphere remains insufficient. Herein, the light‐induced autoxidation...
In the search for sustainable cathode materials for aqueous zinc ion batteries (AZIBs), vanadium (V)‐based materials have garnered interest, primarily due to their abundance and multiple oxidation states. Among the contenders, Li3VO4 (LiVO) stands out for its affordability, high specific capacity, and elevated ionic conductivity. However, its limited electrical conductivity results in significant...
The significant attraction toward aqueous proton batteries (APBs) is attributable to their expedited kinetics, elevated safety profile, and economical feasibility. Nevertheless, their practical implement is significantly blocked by the unsatisfactory energy density due to the limited cathode materials. Herein, vanadium hexacyanoferrate Prussian blue analog (VOHCF) is introduced as a potentially favorable...
The inherent slow diffusion dynamics of aqueous zinc‐ion batteries (AZIBs) act as a significant hindrance to their universal utilization as energy storage systems, largely attributed to the scarcity of superior cathode materials. In this study, a novel method that amalgamates oxygen defect engineering and polymer intercalation, guided by theoretical computations, to confront this challenge, is introduced...
Electrochromic smart windows (ESWs) offer an attractive option for regulating indoor lighting conditions. Electrochromic materials based on ion insertion/desertion mechanisms also present the possibility for energy storage, thereby increasing overall energy efficiency and adding value to the system. However, current electrochromic electrodes suffer from performance degradation, long response time,...
Primary cancer modulates the bone microenvironment to sow the seeds of dormancy and metastasis in tumor cells, leading to multiple organ metastasis and death. In this study, 3D printing and bone‐on‐a‐chip (BOC) are combined to develop a BOC platform that mimics the pre‐metastatic niches (PMNs) and facilitates elucidation of the interactions between bone‐resident cells and metastatic tumor cells under...
CoNi‐LDH (layered CoNi double hydroxides) hollow nanocages with specific morphology are obtained by Ni ion etching of ZIF‐67 (Zeolitic imidazolate framework‐67). The structure of the layered materials is further modified by molecular intercalation. The original interlayer anions are replaced by the ion exchange effect of terephthalic acid, which helps to increase the interlayer distance of the material...
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...
Methicillin‐resistant Staphylococcus aureus (MRSA) biofilm‐associated bacterial keratitis is highly intractable, with strong resistance to β‐lactam antibiotics. Inhibiting the MRSA resistance gene mecR1 to downregulate penicillin‐binding protein PBP2a has been implicated in the sensitization of β‐lactam antibiotics to MRSA. However, oligonucleotide gene regulators struggle to penetrate dense biofilms,...
Perovskite solar cells (PSCs) based on 2D/3D composite structure have shown enormous potential to combine high efficiency of 3D perovskite with high stability of 2D perovskite. However, there are still substantial non‐radiative losses produced from trap states at grain boundaries or on the surface of conventional 2D/3D composite structure perovskite film, which limits device performance and stability...
