Atomic High-Spin Cobalt Unlocks Reversible Multi-Electron Transfer Chemistry for Superb Aqueous Zn-Mn Batteries

Abstract To settle inherent irreversible phase transition and motivate re-dissolution of deposited “dead” MnO 2 without acid and redox mediator addition, we introduced atomic-dispersed Co atoms with high-spin state into layered MnO 2 , denoted as Co–MnO 2 , via an in situ topolog...

Knowledge-Guided Graph iTransformer Enhanced by Reinforcement Learning for Industrial Fault Diagnosis

Complex industrial processes are characterized by strong coupling, nonlinear interactions, and dynamic causal dependencies between variables, posing significant challenges for accurate fault diagnosis. Conventional data-driven methods often fail to effectively exploit structural...

Decouple Intrinsic Activity and Mass Transfer Optimization to Achieve Ultra-High Hydrogen Evolution Reaction Performance at High Current Density

Abstract Improving the hydrogen evolution reaction (HER) performances of the Pt catalysts is important for reducing the cost of proton exchange membrane water electrolyzers. Understanding the origin of the overpotential when Pt/C catalyzes the HER is significant for designing hig...

Structural Water‐Enabled Helicity Emergence From an Asymmetric Achiral Molecule

ABSTRACT Helical supramolecular architectures are ubiquitous in nature yet remain challenging to construct from asymmetric achiral molecules. Here, we demonstrate that structural water acts as a symmetry‐breaking and frustration‐generating element in artificial self‐assembly. Usi...

Direct visualization of RNA virus and evaluation of drug effect in living cells by catalytically transformable DNA cube

In situ visualization of viral RNA in living cells is critical for understanding infection dynamics and evaluating antiviral responses, yet offline methods such as polymerase chain reaction are incompatible with real-time analysis. Here, a CAtalytically Transformable DNA Cube (CA...

Metabolic engineering of Escherichia coli for efficient production of d-phenylglycine

d -phenylglycine (D-PHG) is a valuable building block extensively used in the synthesis of β-lactam antibiotics and other high-value pharmaceuticals. However, its conventional chemical production relies on expensive starting materials and harsh reaction conditions, while existing...

Are corporate cash holdings sensitive to neighborhood carbon emissions?

Abstract As carbon transition and regulatory risks escalate, understanding the impact of local carbon emissions on corporate financial strategies is essential, particularly in shaping cash holding policies to manage environmental liabilities. This study investigates the impact of...

Nanoconfinement Engineering Enables Pt Nanocrystals in MOF-on-MOF Derived Nanoporous Carbon Microspheres for Hydrogen Evolution

Abstract Developing Pt-based catalysts with maximized atomic utilization and optimized electronic structures remains crucial for accelerating the cathodic hydrogen evolution reaction (HER). Herein, we develop a MOF-on-MOF-derived confinement strategy to construct a defect-mediate...

A biodegradable piezoelectric vertebral implant for programmable electro-neuromodulation in spinal cord injury

Spinal cord stimulation has emerged as a promising therapeutic strategy for spinal cord injury (SCI), yet conventional electronic implants remain limited by surgical risk and long-term safety concerns. We introduce a biodegradable piezoelectric cryogel (Piezo Gel) that enables pr...

Axial N Disrupt d –π Conjugation of Asymmetric Fe─Cu Dual‐Atom Enhances CO 2 Electroreduction

ABSTRACT Precise spin‐polarization modulation of electronic structures in dual single‐atomic sites (DSAS) is critical yet challenging for boosting electrocatalytic CO 2 reduction reaction (CO 2 RR). Here, we report a Fe 3 d ‐orbital spin‐polarization regulation strategy through c...

Two‐Dimensional Conjugated Metal Organic Frameworks with Dual Metal Catalytic Active Sites Enhance POD Activity for Antibacterial Treatment

ABSTRACT The emergence of drug‐resistant bacteria has brought a grand challenge to the treatment of oral ulcers (OUs). Peroxidase (POD) enzymes catalyze the conversion of hydrogen peroxide (H 2 O 2 ) into reactive oxygen species (ROS), offering a promising strategy for treating d...

Symbolic or Substantive? The Impact of Managerial Climate Awareness on Firms' Sustainability

ABSTRACT This study examines whether managerial climate awareness contributes to symbolic or substantive sustainability of Chinese publicly listed firms. We find that only when managers' climate awareness is high enough will they significantly drive firms toward substantive susta...

What is happening at the atomic level during the seed-mediated growth of copper on gold?

Bimetallic nanocrystals obtained via seed-mediated growth are typically analyzed using conventional electron microscopy and many interesting features at the atomic level are often missed. Here we report the seed-mediated growth of copper (Cu) on gold (Au) nanospheres for the synt...

Dynamic Resilience Screening of Strait of Hormuz-Induced Trade Squeeze in Global Food Supply Chain Systems

A maritime chokepoint shock can spread beyond the countries directly connected to the affected route. We develop a monthly resilience screening model for a hypothetical Strait of Hormuz closure that separates direct disruption, scarcity-driven trade squeeze, household access pres...

Disuse enhances cancellous and cortical bone responses to mechanical loading by altering lacunocanalicular fluid dynamics

Disuse conditions, such as microgravity, prolonged bed rest, sedentary lifestyle, and limb immobilization, frequently affect human skeletal responses to mechanical loading. However, the precise impact of disuse on bone adaptation to mechanical loading and its underlying mechanobi...
