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...
