Observation of Highly Efficient Electric-Quadrupole Second Harmonic Generation in a Dirac Semimetal

Abstract Topological semimetals hold great promise for nonlinear optics (NLO). It is challenging to probe tilted Dirac fermion-driven intrinsic second harmonic generation (SHG) and topological band structure modulation of second-order nonlinearity in spatial inversion and time-re...

Indium‐Mediated Electrolyte with Efficient Mg 2+ Transport and CO 2 Pathway Selection for Highly Reversible Mg–CO 2 Batteries

ABSTRACT Mg–CO 2 batteries present promising potential for integrated energy storage and carbon fixation, though their advancement is limited by slow cathodic CO 2 conversion kinetics and insufficient reversibility. Here, we report an In‐mediated electrolyte that couples solvatio...

Macrophage FOXO1 Inhibition Protects Against Hyperglycaemia‐Associated Kidney Injury

ABSTRACT Diabetic kidney disease (DKD) is one of the most significant microvascular complications of diabetes, characterized by high incidence and mortality; however, its pathogenesis remains unclear. Renal inflammation and macrophage infiltration play pivotal roles in driving DK...

Dataset Construction of CO2 Flux over Shifting Sand in the Taklimakan Desert and Assessment of Carbon Sequestration Capacity

Desert ecosystems, which cover extensive global regions, play an essential yet often-overlooked role in sequestering atmospheric CO 2 at substantial yet gradual rates, primarily due to insufficient monitoring, data scarcity, and limited research attention. Current assessments of...

Flowering-Stage Heat Stress in Xinjiang Jujube Orchards: Spatiotemporal Evolution, Integrated Risk Assessment, and Multi-Scale Drivers

Jujube is an important economic fruit tree in China, with Xinjiang being the largest production region, where flowering-stage heat stress threatens yield stability. Assessing heat risk in jujube orchards requires consideration of crop-specific phenological sensitivity and heat in...

RBF‐FD Method for Solving the Generalized Time‐Fractional Burgers Equation With Initial Weak Singularity

ABSTRACT This paper develops an efficient numerical algorithm for solving the generalized time‐fractional Burgers equation subject to three classes of boundary conditions, whose solutions possess weak singularities in the vicinity of the initial instant . Traditional numerical ap...

Dose-Dependent Effects and Metabolomic Analysis of Foliar-Applied Carbon Dots on Cotton (Gossypium hirsutum L.) Growth

While carbon dots (CDs) are promising green nanomaterials for sustainable agriculture, how they regulate cotton growth via physiological and metabolic reprogramming remains poorly understood. This study evaluated foliar CD application (0–200 mg·L−1) to uncover dose–response patte...

Synergistic Co-Blending of Low- and High-Rank Coals: A Strategy for Engineering High-Performance Porous Carbons for Supercapacitors

Owing to the inherent limitations of a single coalification degree, precursors derived from a single-rank coal often struggle to simultaneously fulfill the requirements of composition, structure, and performance. To address this, a blended-coal strategy combining oxygen-rich low-...

Research on the impact mechanical response characteristics of gas containing coal and rock based on RSM

To investigate the dynamic mechanical behavior of gas-containing coal in deep coal mines, dynamic compression tests were conducted on gas-containing coal using a 50 mm diameter split Hopkinson pressure bar (SHPB) system. The central composite design (CCD) method within response s...

Integrating deep learning and pangenomics to recover missing heritability from wild structural variations

Crop domestication has induced a severe genetic bottleneck that reduces the adaptive diversity present in modern cultivars. Standard intra-population genomic prediction models reliant on linear reference genomes and SNPs fail to capture the full spectrum of phenotypic variance hi...

Integrated analysis of surface water-groundwater interactions and enhanced hydrological forecasting of glacierized river in cold and arid regions

Abstract In cold and arid regions, climate change has altered precipitation patterns and accelerated glacierized retreat, which imposes severe risks on the stability of regional hydrological systems. Combined with the strong interactions between surface water (SW) and groundwater...

Mechanical properties and fracture failure characteristics of fractured limestone under coupled freeze-thaw and cyclic loading

<title>Abstract</title> The Central Asian Orogenic Belt possesses abundant mineral resources. As mining activities extend into high-altitude cold regions, the safety and stability of rock engineering projects, such as open-pit mine slopes, have become increasingly prominent. This...

Natural variation in LuGnTL modulates the trade-off between plant height and seed size in flax (Linum usitatissimum L.)

Flax is an ancient crop cultivated for both fiber and oil, and it has undergone divergent selection into two distinct morphotypes: semi-dwarf oil flax with large seeds and tall fiber flax with small seeds. However, the genetic architecture underlying the trade-off between plant h...

Compression Deformation Characteristics of Frozen Soil Containing Ice Lenses Under an Asymmetric Temperature Field

Frozen soil on alpine slopes is influenced by inclination and aspect-induced differential solar radiation effects, resulting in non-uniform temperature fields and inclined layered ice lenses that enhance anisotropy and degrade mechanical properties. This study investigates the de...

Manipulating Valence‐Heterogeneous Pt Dual Sites via Metal‐Support Interactions for Highly Efficient Alkaline Hydrogen Evolution
