Decoding Dopant-Induced Electronic Modulation in Graphene via Region-Resolved Machine Learning of XANES

This study combines density functional theory and region-resolved machine learning to demonstrate that the pi* region of XANES spectra is the most informative for predicting Bader charge and bond lengths, thereby establishing a robust method to quantify dopant-induced electronic modulation in boron- and nitrogen-doped graphene.

Plasmon Engineering in Intercalated 2H-TaS2_2

This study demonstrates that transition metal intercalation (Fe and Co) in 2H-TaS2_2 suppresses plasmon modes not through conventional electron doping, but by reshaping the low-energy electronic structure via orbital hybridization and structural reconstruction, thereby providing a chemically controlled pathway to tune plasmonic losses and dielectric responses in van der Waals materials.

Continuous three-dimensional imaging of nanoscale dynamics by in situ electron tomography

This paper presents a novel dynamic electron tomography framework that combines continuous tilting with self-supervised deep learning to enable continuous, dose-efficient 3D imaging of nanoscale structural transformations under operating conditions, overcoming the limitations of traditional static reconstruction methods.

Fe-site-resolved anisotropy energies in Nd2_2Fe14_{14}B for atomistic spin dynamics

This paper addresses the discrepancy in modeling Fe-site magnetocrystalline anisotropy for atomistic spin dynamics simulations of Nd2_2Fe14_{14}B by deriving and validating two models, ultimately demonstrating that anisotropic exchange is essential for accurately capturing Fe contributions that single-ion theory cannot explain.

Thermal Conductivity and Temperature-Induced Band Gap Renormalization in Crystalline and Amorphous Ga2_2O3_3

This study employs a machine-learned moment tensor potential coupled with first-principles calculations to reveal that crystalline β\beta-Ga2_2O3_3 exhibits significantly stronger temperature-induced band gap renormalization and higher lattice thermal conductivity compared to its amorphous counterpart, establishing a reliable computational framework for predicting semiconductor properties under microelectronic operating conditions.

Superlinear Temperature-Dependent Resistivity and Structural Phase Transition in BaNi2_2P4_4

This study reveals that the anomalous superlinear temperature-dependent resistivity in BaNi2_2P4_4 arises from the decay of enhanced residual scattering caused by local Ba rattling as the material undergoes a first-order tetragonal-to-orthorhombic structural phase transition, a mechanism confirmed by electron irradiation, Hall effect, NMR, and Raman scattering data.
