Improved Correlations for the Static Dielectric Constant of Hydrogen

This paper presents improved correlations for the static dielectric constant of para- and ortho-hydrogen over a temperature range of 1 to 1000 K by recalculating low-density contributions with modern ab initio methods and developing new functional representations based on an extensive review of experimental data, thereby significantly enhancing accuracy for cryogenic and liquid states compared to previous models.

Comparison of LMP and MHS+MG Models for Oxidation-Corrected Creep Rupture Life Prediction of Grade 23 Steel

This study demonstrates that the Modified Hyperbolic Sine plus Monkman–Grant (MHS+MG) model outperforms both constrained and unconstrained quadratic Larson–Miller Parameter (LMP) models in predicting the oxidation-corrected creep rupture life of Grade 23 steel by offering superior accuracy, stability, and physically consistent stress–life trends across a wide temperature range.

Distinguishability Geometry of Phase Transitions: A Structural Theory from First Principles

This paper proposes Distinguishability Geometry as a first-principles framework that derives phase transitions as discontinuous changes in the structural invariants of state distinguishability, thereby naturally emerging the Landau order parameter and predicting experimentally verified sensor-dependent transition temperatures that challenge classical thermodynamic assumptions.

Physics-Informed Generative Inverse Design of Stable Vanadium Oxide Crystals with First-Principles Validation

This paper presents a physics-informed generative inverse design framework that couples a voxel-based variational autoencoder with a formation-energy-constrained Wasserstein generative adversarial network to efficiently discover and validate stable vanadium oxide crystal candidates, significantly increasing the yield of thermodynamically stable structures compared to random sampling while reducing the computational burden of first-principles screening.

Influence of Cu2Te Doping on the Microstructure and Phase Formation Process of MgB2 Superconductor

This study demonstrates that doping MgB₂ with 2 wt% Cu₂Te enhances superconducting properties by lowering the phase formation temperature through a eutectic liquid-assisted mechanism and improving critical current density via grain refinement and the introduction of effective flux pinning centers.
