Compensation–Skills Dual-Dimensional Configuration and Sustainable Upgrading of Export Technological Sophistication: A Re-Explanation of the “Value Paradox” of Skill Mismatch

Amid the restructuring of global value chains (GVCs) and the artificial intelligence (AI) revolution, how firms’ reallocation of human capital relates to escaping value chain lock-in has become a question of growing theoretical and practical importance for China. Traditional stat...

Fluorinated Microporous Organic Network-Based Cooling-Assisted SPME for Ultra-Trace Determination of Fluorinated Liquid Crystal Monomers

Abstract Fluorinated liquid crystal monomers (FLCMs), widely used in electronic displays, have emerged as persistent and bioaccumulative contaminants, yet their ultra-trace determination in complex matrices remains challenging. Herein, a cooling-assisted solid-phase microextracti...

Synthesis, Crystallographic Characterization, and Proton-Modulated Physical Properties of an Azulene-Embedded Chiral Nanographene

Abstract The construction of novel nanographenes embedded with non-benzenoid rings offers a promising platform for advanced optoelectronic applications. Postfunctionalization of the tribenzo[a,d,g]coronene scaffold with an azulene unit remains largely undeveloped. Herein, we rati...

Topology-aware dynamic co-evolution for robust graph learning

Graph Neural Networks (GNNs) have achieved remarkable success in learning from graph-structured data. However, recent studies have revealed their vulnerability to adversarial attacks, where imperceptible perturbations to the graph structure can easily mislead predictions. Existin...

Diversity–multifunctionality relationships shift with increasing aridity in grasslands

Grasslands, a dominant global ecosystem, face an uncertain future. Diverse grasslands can maintain multiple functions (multifunctionality); however, the relative roles of species diversity and functional diversity in promoting this resilience remain unclear. We examined how the d...

Photo‐Controlled Treatment for Psoriasis‐Like Skin Lesions by UVB‐Photoactivated Hydrogen Sulfide Donors and Pterostilbene

ABSTRACT Smart and efficient drug delivery is always desirable, especially for chronic diseases, such as psoriasis. We developed an ultraviolet B (UVB) light‐triggered scaffold, 1,4,2‐dioxazol‐5‐thione (DOT), for the controlled release of hydrogen sulfide (H 2 S), a pivotal endog...

The generation and characterization of CTRP9-CreERT2 knock-in mice for targeting endothelial cell muscle and adipose tissues

Vascular endothelial cells (ECs) exhibit significant diversity in different tissues. To elucidate the distinct physiological roles of individual EC subtypes, genetic mouse lines utilizing the Cre-loxP recombination system are crucial. However, there is still a lack of Cre mouse l...

Post‐Oxidation Integrating Assembly‐Confined Pyrolysis to Boost POD‐Like Activity of Non‐Metal Nanozyme and Engineer Colorimetric Hydrogel for On‐Site Detection of PFAS

Abstract Nanozymes have become attractive candidates for advanced sensors, yet enhancing peroxidase (POD)‐like activity of non‐metal nanozymes with minimized oxidase activity interference and broad‐spectrum recognition capability for per‐ and polyfluoroalkyl substances (PFASs) re...

Time-varying and nonlinear effects of climate policy uncertainty on air pollution and carbon emissions in China: combination of TVP-VAR and QQA

Climate policy uncertainty (CPU) can alter the predictability of mitigation pathways, yet its environmental benefits may differ across time horizons and transition stages for pollutants or carbon emissions. Because air pollutants and CO 2 are often co-emitted through fossil-fuel...

An accelerated branch-and-cut algorithm for globalized robust sustainable biomass supply-chain optimization under uncertainty

This article addresses the optimal design of a sustainable biomass supply chain under multiple sources of uncertainty, including fluctuating transportation costs and ambiguity in the demand distribution. A globalized robust bi-objective optimization model is proposed that integra...

Experimental study on the influence of pupil diameter on laser‐induced retinal damage effects

Abstract To investigate the impact of pupil diameter on laser‐induced retinal damage, this study employed 473 nm and 1064 nm lasers to irradiate the retinas of Chinchilla rabbits, with an exposure duration of 0.1 s. Apertures of 2 and 5 mm were placed in front of the dilated eyes...

Application and prospects of high-temperature heat pipe technology in concentrating solar thermal collector systems

Against the backdrop of global energy transition, concentrated solar thermal (CST) collector systems offer efficient conversion of solar energy into high-grade thermal energy, representing a critical pathway for renewable energy development. However, the synergistic enhancement o...

Buckling behavior of steel bars with different strength grades subjected to random corrosion: An experimental and multi-method predictive study

The random morphology caused by corrosion significantly damages the compressive buckling performance of steel bars. Differences in chemical composition across strength grades lead to distinct corrosion morphologies, affecting mechanical properties. Buckling behavior under compres...

Cascade Spirocyclization–Difunctionalization or Rearrangement of Bicyclobutyl-Tethered Aldehyde Hydrazones via Strain Release

Abstract A cascade spirocyclization–difunctionalization of bicyclobutyl-tethered aldehyde hydrazones with N-halosuccinimides was smoothly performed to access diverse halo-succinimide-containing diazaspiro[3.3]heptan-3-ones. Meanwhile, the three-component rearrangement of bicyclob...

Underground Signals: The Ecological Power of Root Volatiles

Root volatiles mediate diverse belowground interactions among plants, microbes, and invertebrates, but biological and environmental conditions strongly influence their production, movement, perception, and ecological effects. This review synthesizes current knowledge through an i...
