Quantum-Dot-Based Organic Framework Nanostructures: Engineering toward Enhanced Optical Properties

Abstract Functional nanostructures are widely designed and investigated for their broad applications in optoelectronic devices, biomedicine, and catalysis, among them, framework nanostructures attracted much attention for their compatibility with ions, functional molecules to wid...

Dual effect of calcium ions on sodium oleate adsorption and spodumene flotation

The flotation of spodumene with sodium oleate is highly sensitive to calcium concentration, but the underlying interfacial mechanisms remain unclear, especially under inhibitory conditions. To address this, we systematically investigate how calcium ions govern the spodumene-oleat...

Molecular dynamics study of high-temperature creep in carbon-rich amorphous silicon carbide: The role of local coordination

The high-temperature creep resistance of polymer-derived carbon-rich amorphous silicon carbide (a-SiC) is critical for its application in extreme environments; however, the atomistic origins of its viscoplastic flow remain debated. In this study, molecular dynamics simulations co...

Nacre-inspired hydroxylated BNNS/aramid composite paper with interfacially engineered lamellar networks for efficient thermal conduction

The intrinsically low thermal conductivity of traditional aramid paper hinders its application in next-generation high-power electrical systems. Although incorporating thermally conductive fillers is a common strategy, it often leads to severe filler agglomeration and interfacial...

Investigation of CO2-to-methanol hydrogenation performance over Cu-ZnO/ZrO2 catalysts by tuning ZrO2 crystalline phases

Cu-ZnO/ZrO 2 catalysts are promising for CO 2 hydrogenation to methanol, yet the role of ZrO 2 phase composition remains unclear. Here, monoclinic and tetragonal ZrO 2 were separately prepared and combined to construct catalysts with systematically varied m/t-ZrO 2 compositions....

Urban electricity demand in response to price surges: Evidence from three U.S. cities

Urban electricity systems are increasingly exposed to volatile energy prices, yet the behavioral response of consumers to extreme price shocks remains poorly quantified. The historic surge in electricity prices in many world cities from late 2022 to early 2023 provides a unique o...

From narrative to action: A hierarchical cognitive large language model agent framework for interpretable and adaptive human mobility behavior generation

Understanding and replicating human mobility requires not only spatial–temporal accuracy but also an awareness of the cognitive hierarchy underlying real-world travel decisions. Existing approaches often lack interpretability and struggle to represent adaptive behavior under chan...

Ultrahigh flow strength in shocked nanopolycrystalline diamond

Extreme pressures and temperatures create conditions that allow even hard and brittle materials to flow plastically. Despite extensive research, the limits of flow strength under such conditions remain uncertain, and the mechanisms driving deformation at the relevant stresses are...

Research on automatic segmentation method of microseismic monitoring signal under low signal-to-noise ratio conditions

To address the issues of reduced microseismic signal detection accuracy and difficulty in identifying event boundaries under low signal-to-noise ratio conditions, we propose SEU-Net, an automatic microseismic signal segmentation model that integrates a Squeeze-and-Excitation (SE)...

Nano‐Architectural Evolution and Hybridization Dynamics in Carbon Nanocoatings Under Electro‐Mechanical Coupling

ABSTRACT Current‐carrying tribological interfaces suffer from severe electrical corrosion because coupled electrical, mechanical, and tribochemical interactions continuously drive interfacial degradation. Although carbon‐based films exhibit excellent tribological and electrical p...

Hukou-based residential composition, inbound routine activity mobility, and recorded theft in Shanghai

Crime-and-place research increasingly distinguishes residential context from the populations that enter neighborhoods through daily activity. This study examines whether inbound routine activity mobility is associated with recorded theft differently across Shanghai communities wi...

Smart Prediction of Carbon Emissions in Bridge Construction: An Empirical Study Using Multi-Dimensional Machine Learning

Transportation infrastructure construction generates substantial greenhouse gas emissions, yet construction-phase emissions from small- and medium-span concrete bridges remain difficult to quantify at the design stage. This study develops a data-driven framework for carbon accoun...

Cofixation of NH3 and CO2 through Cyclic Diarylchloronium Salt-Triggered Ring-Opening Bifunctionalization of Unstrained Cyclic Amines

Abstract We report a mild and general strategy for the cofixation of NH3 and CO2 via cyclic diarylchloronium salt-triggered ring-opening bifunctionalization of unstrained cyclic amines. This method employs readily available aqueous NH3 and CO2 as nitrogen and carbon feedstocks, d...

Emerging compound air-soil heatwaves amplify global vegetation losses

Abstract Compound air-soil heatwaves—periods in which extreme air and soil temperatures co-occur—pose a growing threat to terrestrial ecosystems, yet their occurrence and impacts remain poorly understood. Here, we show that compound air-soil heatwaves have become more frequent (0...

Coordination‐Driven Pt(II)‐Ru(II) Heterometallacycles With Ultrastrong Cathodic Electrochemiluminescence and Guest‐Responsive Signal Amplification

ABSTRACT Coordination‐driven self‐assembly enables the integration of multiple functional elements within a single supramolecular architecture. By combining emissive chromophores, optimized electronic structures, and confined microenvironments, it provides an effective strategy f...

Wnt2bb-triggered neighbor cell proliferation is essential for cloaca formation by inducing apoptosis in the cloaca through cell competition

Cloaca serves as the only opening for the digestive, urinary, and reproductive tracts in multiple species. Apoptosis is crucial for shaping the cloaca, yet the underlying mechanisms remain largely unclarified. Here we find that Wnt2bb-triggered neighbor cell proliferation is esse...

The Supply Chain Ripple Effect of Customer Environmental Regulatory Pressure: A Perspective on Suppliers' Financial Asset Allocation

ABSTRACT Using data from Chinese A‐share listed firms and their top five customers over the period 2010–2023, this study finds that supplier firms allocate more financial assets when their customers face higher environmental regulatory pressure and that this effect is primarily d...

Single-ended fault location method for multi-terminal overhead-cable hybrid transmission line using alternating search algorithm
