Distributive effects of climate change: How does rising temperatures affect energy allocation between cities?

The impact of rising temperatures on cities is heterogeneous, leading to a reallocation of energy between cities. However, whether this redistribution is detrimental remains unclear. Based on panel data of 261 cities in China from 2006 to 2021, this study examines how rising temp...

Machine Learning-Based Prediction of Elemental Distribution Rates in Pyrometallurgical Copper Production

Understanding elemental distribution among slag, dust, and copper-bearing products during pyrometallurgical copper production is critical for minimizing valuable metal losses, controlling potentially hazardous elements, and improving resource recovery. However, prediction of elem...

Toward Rational Design of Aqueous Battery Membranes Beyond the Selectivity‐Conductivity Trade‐Off

ABSTRACT Electrochemical energy‐storage systems increasingly require membranes that can simultaneously deliver fast ion transport, suppressed active‐species crossover, chemical and dimensional stability, and scalable manufacturability. Yet conventional membrane platforms still st...

Commutability Assessment of Materials for Serum Copper Measurement Using the IFCC Difference-in-Bias and the CLSI EP30 Approaches

Background: Evidence on the commutability of material for serum copper when assessing multiple material categories and assay pairs remains limited. Methods: We evaluated 21 reference materials for serum copper across four routine colorimetric systems and an inductively coupled pl...

Physics-consistent alignment and discrepancy learning for multi-fidelity prediction of train collision load

Train collision accidents may lead to severe casualties and substantial property losses, making crashworthiness analysis essential for improving train passive safety. However, the high computational cost of high-fidelity numerical simulations limits their direct application to la...

Breaking the High-Voltage Limit of Na2CO3 Presodiation: An Interfacial Engineering Approach to Ampere-Hour Sodium-Ion Devices

Abstract Na2CO3 is a promising sacrificial presodiation agent owing to its high capacity, excellent air stability, and low cost. However, its practical application is severely hampered by a high decomposition overpotential (>4.3 V vs Na/Na+), inducing detrimental electrolyte oxid...

Resolving Proton Diffusion Kinetics in Electrolytic Hydrogen Evolution

Abstract Although the hydrogen-bond network within the electrical double layer (EDL) is crucial for proton diffusion in the hydrogen evolution reaction (HER), its exact role remains controversial. This debate stems from the experimental difficulty in determining the proton diffus...

Harnessing Plasmonic Cu2− x Se Transducers for Quantitative Near-Infrared II Photothermal Lateral Flow Exosome Detection

Abstract Photothermal lateral flow assays (PT-LFAs) hold immense promise for advancing point-of-care (POC) diagnostics into the realm of robust, on-site quantitative analysis. However, their clinical translation remains fundamentally constrained by the absence of high-performance...

Cation-Gated Interfacial Electrocatalysis: Mechanisms and Effects of Alkali and Alkaline Earth Metal Cations

Abstract Electrolyte cations, long considered inert charge-balancing species, are now recognized as active regulators of electrocatalytic interfaces. This review systematically examines alkali metal cations (Li+, Na+, K+, Rb+, Cs+) and alkaline earth metal cations (Mg2+, Ca2+, Sr...

Impulsivity, cognitive inflexibility, and brain network dysregulation in etomidate use disorder: A clinical and EEG microstate study

Etomidate, a short-acting GABA_A receptor modulator and emerging novel psychoactive substance, is increasingly abused non-medically. Despite rising clinical concern, the neuropsychological profiles of etomidate use disorder (EUD) remain poorly characterized, prompting this system...

Magnetically Reconfigurable Noncollinear Excitonic Polarization in a MoSe 2 /CrOCl/Fe 3 GaTe 2 Heterostructure

ABSTRACT Van der Waals (vdW) heterointerfaces provide a versatile platform for tailoring polarization‐resolved excitonic emission in 2D semiconductors, offering new opportunities for polarization‐encoded photonic functionalities. However, the realization of distinct and externall...

β3‑adrenergic receptor agonist improves recovery after volumetric muscle loss and is associated with increased intramuscular brown/beige adipogenic activity in mice

Abstract Background Volumetric muscle loss (VML) often results in chronic muscle weakness, limb dysfunction, and even permanent disability. Current research primarily focuses on cell and extracellular matrix transplantation, but there is a lack of studies on the physiologically s...

Mitochondrial Protection and Neural Repair via ROS‐Responsive Biomimetic Nanoparticles in Intracerebral Hemorrhage

ABSTRACT Intracerebral hemorrhage (ICH)‐induced secondary brain injury is driven in part by oxidative stress, blood‐brain barrier disruption, mitochondrial dysfunction, and neuronal loss. Here, we developed a brain endothelial cell membrane‐coated ROS‐responsive biomimetic nanopl...

Between-cohort variation in the cardiovascular association and predictive utility of the triglyceride-glucose waist circumference index among ageing adults in China, England, and the United States

Low-cost metabolic indices could support cardiovascular screening, but their utility may vary across populations. We evaluated between-cohort variation in the association, incremental predictive value, and absolute-risk performance of the triglyceride-glucose waist circumference...

Effects of LM-PAEK film thickness and processing parameters on interfacial remelting and lap-shear strength of overmolded CF/PEEK joints

Injection overmolding of short carbon fiber reinforced PEEK onto continuous carbon fiber reinforced PEEK (cCF/PEEK) laminates is promising for lightweight composite structures. However, the high melting temperature of PEEK often leads to insufficient interfacial remelting due to...
