Many different types of inorganic materials are processed into nano/microparticles for medical utilization. The impact of selected key characteristics of these particles, including size, shape, and surface chemistries, on biological systems, is frequently studied in clinical contexts. However, one of the most important basic characteristics of these particles, their density, is yet to be investigated...
Two‐dimensional nanofluidic membranes offer great opportunities for developing efficient and robust devices for ionic/water‐nexus energy harvesting. However, low counterion concentration and long pathway through limited ionic flux restrict their output performance. Herein, it is demonstrated that rapid diffusion kinetics can be realized in two‐dimensional nanofluidic membranes by introducing in‐plane...
Metal phase molybdenum disulfide (1T‐MoS2) is considered a promising electrocatalyst for hydrogen evolution reaction (HER) due to its activated basal and superior electrical conductivity. Here, a one‐step solvothermal route is developed to prepare 1T‐MoS2 with expanded layer spacing through the derivatization of a Mo‐based organic framework (Mo‐MOFs). Benefiting from N,N‐dimethylformamide oxide as...
While the solid‐state nanopore shows increasing potential during sensitive and label‐free single molecular analysis, target concentration and signal amplification method is in urgent need. In this article, a solution via designing a model nucleic acid circuit reaction that can produce “Y” shape‐structure three‐way DNA oligomers with controllable size and polymerization degree is proposed. Such a so‐called...
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. Herein, a donor–acceptor modified Cu porphyrin (CuTAPP) is developed,...
Natural polymer‐based sutures have attractive cytocompatibility and degradability in surgical operations. Herein, anionic cellulose nanofibrils (ACNF) and cationic guar gum (CGG) are employed to produce nontoxic CGG/ACNF composite filament with a unique core–shell structure via interfacial polyelectrolyte complexation (IPC) spinning. The comprehensive characterization and application performance of...
Aqueous Potassium Ion Supercapacitors
A covalently interlayer‐confined polyaniline–MoS2 hybrid with a dual charge storage mechanism is developed for supercapacitors. In the hybrid, confined polyaniline induces a favorable phase transition, facilitates cross‐layer electron transfer, and decreases K+ diffusion barrier, thus enabling high electrochemical performance. More details can be found in article...
Anti‐Infection Therapies
In article number 2205471, Jianqing Gao, Fangyuan Li, Daishun Ling, and co‐workers report a silver‐based enzymatic nanoadjuvant (EnzNA) by self‐assembling silver nanoclusters that can modulate intracellular and extracellular infectious microenvironments with pH discrepancy to overcome antimicrobial resistance of pathogens. The EnzNA‐mediated modulation of the infectious microenvironment...

In article number 2206155, Cailei Yuan and co‐workers report a single‐atom catalyst (Gd@MoS2) with long range room temperature ferromagnetic spin alignment that exhibits significant improvements in catalytic kinetics under alternating magnetic field (AMF) excitation. This increase in catalytic activity is attributed to the atomic‐level magnetic heating effect resulting...
Potassium‐ and sodium‐ion batteries (PIBs and SIBs) have great potential as the next‐generation energy application owing to the natural abundance of K and Na. Antimony (Sb) is a suitable alloying‐type anode for PIBs and SIBs due to its high theoretical capacity and proper operation voltage; yet, the severe volume variation remains a challenge. Herein, a preparation of N‐doped carbon‐wrapped Sb nanoparticles...
Strain engineering of electrocatalysts provides an effective strategy to improve the intrinsic catalytic activity. Here, the defect‐rich crystalline/amorphous Pd nanosheet aerogel with hybrid microstrain and lattice strain is synthesized by combining laser irradiation and phosphorus doping methods. The surface strain exhibited by the microstrain and lattice strain shifts the d‐band center of the electrocatalyst,...
The emergence and evolution of antimicrobial resistance (AMR) pose a significant challenge to the current arsenal to fight infection. Antibiotic adjuvants represent an appealing tactic for tackling the AMR of pathogens, however, their practical applications are greatly constrained by the harsh infectious microenvironment. Herein, it is found that silver nanoclusters (Ag NCs) can possess tunable enzymatic...
Helicobacter pylori (H. pylori) infection has been the leading cause of gastric cancer development. In recent years, the resistance of H. pylori against antibiotic treatment has been a great challenge for most countries worldwide. Since biofilm formation is one of the reasons for the antibiotic resistance of H. pylori, and phototherapy has emerged as a promisingly alternative antibacterial treatment,...
As one of the most promising cathode materials in sodium‐ion batteries, manganese‐based layered oxides have aroused wide attention due to their high specific capacity and plentiful reserves. However, they are plagued by poor air stability rooting in water/Na+ exchange and adverse structural reconstruction, hindering their practical applications.
