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...

Thermally Modulated Microfluidic Fabrication of Phase-Tunable Cs4PbBr6/CsPbBr3 Hybrid Perovskite Nanocrystals for White Light-Emitting Diodes

All inorganic CsPbBr3 perovskite nanocrystals (NCs) exhibit outstanding luminescence for optoelectronics, yet poor environmental stability severely restricts their practical deployment. As a stable derivative phase, Cs4PbBr6 can effectively improve structural stability. Neverthel...

Coupling Landscape Patterns and Ecosystem Services With Sustainable Development Goals for Regional Sustainability: Evidence From the Yellow River Basin

ABSTRACT Human activities are accelerating ecosystem degradation, making regional sustainability transitions increasingly urgent. Although the United Nations Sustainable Development Goals (SDGs) provide a unified global framework for action, their implementation at the regional s...

Beyond Morphological Conservatism: Integrative Taxonomy Unveils Remarkable Cryptic Diversity in the Tachysurus virgatus (Oshima 1926) Group (Siluriformes: Bagridae) Endemic to the Northern Margin of East Asian Tropics

The northern margin of the East Asian tropics harbors exceptional endemism, yet its freshwater fish fauna remains poorly characterized. Tachysurus virgatus, long considered a single widespread species in this region, exemplifies this taxonomic gap. Through integrative taxonomic a...

Study on the Promotion of Methane Hydrate Formation by Surface Modification of Quartz Sand

Natural gas hydrates, with their vast reserves and high gas storage density, have emerged as a highly promising alternative energy source and technology for gas storage and transportation. Wettability, as a core surface property of porous media, directly influences hydrate nuclea...

An N-acetylated daropeptide modulates nematode development

The symbiotic bacterium Photorhabdus is a rich source of bioactive secondary metabolites that mediate tripartite interactions with nematodes and insect hosts. However, natural products of ribosomal origin remain largely underexplored within this ecological niche. Here, we report...

Antioxidant nanozymes for regenerative medicine: mechanisms, design, and applications in tissue repair

Natural antioxidant enzymes play a central role in regulating oxidative stress within living organisms. During tissue repair following injury, these enzymes act synergistically to scavenge excess reactive oxygen species and maintain cellular redox homeostasis, thereby supporting...

CDGP-Net: Channel-Decoupling and Geographic-Prior Fusion for Spatial Super-Resolution of HIRAS Radiances with Co-Platform MERSI-II

Hyperspectral infrared sounders provide valuable observations for numerical weather prediction (NWP), but their native nadir spatial resolution of approximately 12–16 km is coarser than the approximately 4 km grid spacing commonly used in convection-permitting regional forecastin...

A Microseismic Energy Field Distribution Prediction Method Guided by Geological Structure Priors

Existing microseismic prediction methods commonly incorporate domain prior knowledge as ordinary input features, which makes it difficult to fully exploit its structural constraints and physical implications. To address this limitation, this study proposes a geological-structure-...

From Spatial Evolution to Low-Carbon Transition: Regional Heterogeneity and Stage Diagnosis of Carbon Emissions Across 19 Urban Agglomerations in China

Understanding the spatiotemporal dynamics of carbon emissions and developing differentiated governance strategies for urban agglomerations are essential for achieving regional low-carbon transformation. This study aims to identify the spatiotemporal patterns, driving mechanisms,...

Constructing High-Transparency, Self-Healing and Reprocessable Poly(thiourethane) Elastomers Based on Zn2+-Multidentate Pyrimidine Coordination

To develop self-healing polyurethane materials with high transparency and superior mechanical performance, in this work, the poly(thiourethane) elastomers were prepared by incorporating the dynamic thiourethane bonds via thiol–isocyanate click reaction, followed by the addition o...

MedKGent: a large language model agent framework for constructing temporally evolving medical knowledge graph

The rapid expansion of medical literature challenges the scalable structuring of domain knowledge. Knowledge Graphs (KGs) offer a solution, yet current construction methods lack generalizability and ignore the temporal dynamics of evolving knowledge. To address this, we introduce...

Trichoderma-Enabled Crop Resilience Under Abiotic Stress: From Field Delivery to Systems-Level Stress Reprogramming

Abiotic stresses increasingly threaten crop productivity, whereas reliance on chemical and resource-intensive interventions can compromise environmental sustainability. Existing literature identifies Trichoderma spp. as multifunctional biocontrol agents, biofertilizers, and micro...

Trends and Lagged Cumulative Associations Between Vegetation NDVI and Extreme Climate Indices in the Yangtze River Basin: A 41-Year Observational Analysis

Extreme climate events can disturb vegetation dynamics and alter ecosystem stability. This study investigated the evolution of extreme climatic conditions and vegetation greenness across the Yangtze River Basin during 1982–2022 by integrating CN05.1 daily meteorological records w...

Detailed study of non-equilibrium characteristics of quasi-neutral TNSA plasmas

In an experiment performed in November 2022 at the petawatt (PW) laser facility at Vega III located in Salamanca-Spain, we have studied the successful production of several radioisotopes using protons accelerated by the Target Normal Sheath Acceleration (TNSA) mechanism (Rodrigue...

Tribological Behavior and Attachment Force Regulation of Bioinspired Claw–Spines

This study investigates the tribological behavior of the attachment force between bio-inspired claw–spines and rough surfaces and conducts theoretical and model-based analyses of the corresponding attachment mechanism. Based on critical interfacial tribological theory, a friction...

BCL9 inhibition promotes fibroblast lipogenesis by regulating macrophage–fibroblast interactions to attenuate pulmonary fibrosis

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal interstitial lung disease with an urgent need for novel therapeutic strategies. M2 macrophage-derived TGF-β1 promotes fibroblast myogenesis, contributing to IPF pathogenesis. Targeting macrophage polarization and fibr...

Deep N-glycoproteomic profiling of FFPE tissues enables precise diagnosis of primary liver cancer from metastatic liver cancer

Reliable tumor origin assessment from routinely archived specimens remains challenging, particularly for diagnostically ambiguous liver malignancies. Although formalin-fixed, paraffin-embedded (FFPE) tissues are widely available, deep and quantitative site-specific N-glycoproteom...
