Seismic upgrading of an RC frame building using double-stage yield buckling-restrained braces

Nowadays, a large number of existing reinforced concrete (RC) structures require strengthening to meet the new building functions and enhanced seismic demands. Double-stage yield buckling-restrained braces (DYBRBs), capable of yielding at different seismic intensities, offer a pr...

Ecotypic variation and inducible accumulation responses of Leersia hexandra Swartz under Cu(II) and Ni(II) co-contamination

Heavy metal co-contamination is a global challenge for phytoremediation, particularly in regions impacted by mining and electroplating industries, where the selection of plant materials with stable and resilient accumulation traits remains a key bottleneck. This study investigate...

Phosphoric Acid Cross-linking Regulates Closed Pores for Scalable Hard Carbon Anodes

Abstract The low-voltage capacity of hard carbon anodes, governed by closed-pore structures, directly determines the energy density of Na-ion batteries (NIBs), yet rational regulation of closed pores remains challenging. Herein, we report a phosphoric acid-induced cross-linking s...

Evolution of the Deep Channels in the Hechangzhou Anabranching Reach Under the Regulation of Submerged Dikes

The Hechangzhou Anabranching Reach is a typical tidal anabranching segment of the Yangtze River with intense riverbed evolution driven by altered water-sediment regimes and channel regulation. Submerged dikes stabilize river regimes and navigation yet trigger differential local c...

From graph Laplacian to ring polymer dynamics: part I

Abstract A graph-theoretic formulation of overdamped Langevin dynamics and constitutive equations for ring polymers is developed. The polymer molecule is represented as a bead–spring network whose connectivity is described by a graph Laplacian. Starting from overdamped stochastic...

Quantifying the Correlation Between Capacity Utilization and Electrolyte Dosage for Ultrahigh‐Energy‐Density 769 Wh Kg −1 Rechargeable Lithium Metal Batteries

ABSTRACT The pursuit of high‐energy‐density lithium metal batteries requires simultaneous optimization of electrode architecture, electrolyte formulation, and interfacial stability. Here, we establish a fundamental parameter g(σ e , D e ) that quantifies the relationship between...

Se4+-Doped Indium-Based Perovskites via NaCl-Driven Structural Transformation for Dynamic Luminescence Modulation in Multimodal Anti-counterfeiting and Encryption

Abstract The growing risks of counterfeiting and information security breaches have spurred the demand for high-security stimuli-responsive optical materials. However, many reported materials exhibit discontinuous luminescence switching or require harsh external stimuli. Herein,...

Rainfall-Pattern-Dependent Regulation of Hillslope Erosion by Vegetation Conservation Measures in Subtropical Hilly Farmland: A Multi-Method Analysis

The Southern Jiangsu hills region is located within the Yangtze River Delta Ecological Barrier. Soil erosion poses a threat to the development of commercial forests and the water quality of Lake Taihu, making it urgent to quantify the mechanisms by which vegetation and rainfall r...
