Generalized Chemical Model for Warm Dense Hydrogen: Ionization Potential Depression and Molecular Dissociation Shifts

Contributions to Plasma Physics, EarlyView.
ABSTRACT Warm dense matter (WDM) is a complex state, where quantum effects, thermal excitations, and strong interparticle correlations coexist. Understanding its microscopic composition and medium‐induced modifications of atomic and molecular properties is essential for planetary modeling, fusion research, and high‐energy‐density experiments.

ZnO‐Coated Silicon Oxide Nano‐Anode: Synergistic Enhancement of Cycling and Thermal Stability of Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

One‐Step Synthesis of Si–Graphene Heterostructures via in‐Flight Gas‐Phase Mixing for High‐Capacity Silicon‐Rich Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A one‐step gas‐phase synthesis directly assembles amorphous Si nanoparticles with few‐layer graphene heterostructures via in‐flight mixing. Compositions with only 15 wt.% FLG deliver ~2800 mAh g−1 (Si + FLG) at 0.05 C and retain ~1400 mAh g−1 after 100 cycles at a high cycling rate of 1 C, enabled by a percolated, strain‐buffering graphene network that

Hydride Nitrides: Crystal Structure Redetermination of LiSr2H2N and the Isostructural LiBa2H2N

European Journal of Inorganic Chemistry, EarlyView.
The quaternary hydride nitrides LiSr2H2N and LiBa2H2N are obtained in a non‐centrosymmetric crystal structure, different from previous reports. Crystal growth of the honey‐ and pale‐yellow compounds and essentially single phase synthesis is successful using alkali metal flux. The resulting fully ordered structures do not account for a structural reason

Evaluating Forecasts at Multiple Horizons: An Extension of the Diebold–Mariano Approach

Journal of Forecasting, EarlyView.
ABSTRACT Forecast accuracy tests are fundamental tools for comparing competing predictive models. The widely used Diebold–Mariano (DM) test assesses whether differences in forecast errors are statistically significant. However, its standard form is limited to pairwise comparisons at a single forecast horizon.

Single-star Warm-Jupiter Systems Tend to Be Aligned, Even around Hot Stellar Hosts: No T eff–λ Dependency

The Astrophysical Journal Letters
The stellar obliquity distribution of warm-Jupiter systems is crucial for constraining the dynamical history of Jovian exoplanets, as the warm Jupiters’ tidal detachment likely preserves their primordial obliquity.
