Negative‐Thermal‐Expansion Strategy Enables Hard Carbon With Tuned Heat/Strain Tolerances for Sodium Storage

ABSTRACT The thermal/stress runaways pose a risk to the safety and industrialization of sodium‐ion battery (SIB), which hence requires external management equipment. Actually, the thermal/stress generation originates from the repetitive Na + intercalation within carbon interlayer...

Moving-target-enclosing control of nonholonomic MASs with bearing-only measurements and collision avoidance

This paper focuses on a moving-target-enclosing control problem for nonholonomic multi-agent systems with bearing-only measurements and collision avoidance. Due to the lack of distance measurements, a bearing-only observer is designed first to estimate the complete relative posit...

Fragment-Specific Stable Carbon Isotope Analysis for Screening the Authenticity of Red Yeast Rice Products

Monacolin K (MK) in red yeast rice (RYR) is structurally identical to pharmaceutical lovastatin in its lactone form, making their origins difficult to distinguish. This study examined the δ13C value of hydrolysis-derived 2-methylbutyric acid (2-MBA) as a fragment-specific screeni...

Interfacial Oxophilicity Engineering Modulates Surface Hydroxyl Chemistry for Enhanced Electrocatalytic Nitrogen‐to‐Nitrate Conversion

ABSTRACT Electrocatalytic nitrogen oxidation offers an ambient route to nitrate, but the competition between oxygenated intermediates and N 2 adsorption limits efficient nitrate formation. Here, we construct a La 2 O 3– Co 3 O 4 heterojunction to regulate the interfacial oxygen/h...

Condensation Sink Efficiency of Atmospheric Particles Regulated by Their Chemical Compositions and Hygroscopicity

Abstract Condensation sink (CS) from atmospheric pre-existing particles is a crucial limiting factor for the occurrence of new particle formation (NPF). However, intense NPF events occur frequently in polluted urban areas despite high CS levels. Here, to address this discrepancy,...

Ca2+-Triggered Reinforcement of Polyacrylamide/Sodium Alginate Composite Nanogel Spheres for Regulating Multiphase Transport in Low-Permeability Heterogeneous Porous Media

Low-permeability heterogeneous porous media commonly exhibit preferential flow through high-permeability channels and persistent residual-oil trapping in small pores and dead-end regions, limiting effective multiphase transport and residual-oil mobilization. Herein, Ca2+-responsi...

Oxygen-vacancy-rich LDH sonosensitizers potentiate narrow-spectrum antibiotics via membrane-disruption strategy for mixed bacterial wound infections

Mixed bacterial infections, including Gram-positive and Gram-negative pathogens, remain a major global health concern. Achieving efficient treatment of synergistic polymicrobial infections stills a tremendous clinical challenge due to antibiotic permeability barriers and resistan...

Salt Spray Resistant Silver‐Plated Graphite Flake/Polyurethane Foam for Efficient Electromagnetic Interference Shielding

ABSTRACT Porous polymer‐matrix electromagnetic interference (EMI) shielding composites can effectively lower density, and their multiple interfaces facilitate microwave attenuation by enhancing the internal scattering of electromagnetic waves. However, owing to the large specific...

Controlled assembly of MoSe2/N-doped carbon nanoflower spheres via coordination-induced precursor for superior sodium-ion storage
