Influence of Ni Doping on the Structural, Morphological, Optical, and Electrical Properties of Nanocrystalline Cd1-xMnxS Thin Films

This study demonstrates that Ni-doping of Cd1x_{1-x}Mnx_xS thin films prepared via chemical bath deposition enhances crystallinity, increases grain size, and reduces the optical band gap, making them promising photoconducting window layer materials for optoelectronic applications.

Alterations in Conformations of Poly(3-hexylthiophene) on Au(111) Induced by Annealing

Using high-vacuum electrospray deposition and scanning tunneling microscopy, this study demonstrates that the conformation of individual P3HT chains on Au(111) is controlled by the interplay between thermal energy and the regularity of the substrate's reconstructed surface potential.

Pressure-Temperature Phase Diagram and λ\lambda-Transition in Liquid Sulfur

Using machine-learned molecular dynamics simulations, this study provides a microscopic explanation of sulfur's λ\lambda-transition by demonstrating how temperature-induced formation of non-S8_8 rings triggers polymerization, ultimately mapping a pressure-temperature phase diagram that reveals a critical point where polymerization merges with the melting line.

Mechanical Scaling Laws and Deformation Behavior of Nanoporous Tantalum Microparticles

This study demonstrates that nanoporous tantalum produced via liquid metal dealloying follows classical Gibson-Ashby scaling laws due to enhanced ligament connectivity, distinguishing its mechanical behavior from that of nanoporous gold and highlighting solvent chemistry as a key factor in tuning the properties of nanoporous metals.

Physical scaling laws in dislocation microstructures and avalanches from dislocation dynamics simulations

Through extensive 3D dislocation dynamics simulations of FCC Cu, this study resolves inconsistencies in avalanche statistics by demonstrating that the power-law exponent is invariant to dislocation density and loading direction, while the truncation scale is strictly controlled by density, thereby providing robust scaling laws for predictive plasticity modeling.

Accurate predictive model of band gap with selected important features based on explainable machine learning

This study demonstrates that applying explainable machine learning techniques to prune irrelevant and correlated features from a support vector regression model yields a simplified, five-feature predictor for material band gaps that maintains high accuracy while significantly improving generalization and interpretability for materials discovery.

Beyond Diamond: Interpretable Machine Learning Reveals Design Principles for Quantum Defect Host Materials

This paper introduces a composition-only machine learning framework based on heterogeneous Rashomon set ensembles to identify design principles for quantum defect host materials, successfully screening 45,000 compounds to predict 122 high-confidence candidates—including TiO2_2 and layered chalcogenides—that are validated by density functional perturbation theory calculations.
