Enhancing Empirical Energy Functions Using Physics‐ and Machine Learning‐Based Extensions: Structure, Dynamics and Spectroscopy of Modified Benzenes

open access: yesJournal of Computational Chemistry, Volume 46, Issue 21, 05 August 2025.
Quantifying effects of judiciously chosen physics‐ and ML‐based replacements to a generic empirical force field. ABSTRACT The effects of replacing individual contributions to an empirical energy function are assessed for halogenated benzenes (X‐Bz, X = H, F, Cl, Br) and chlorinated phenols (Cl‐PhOH).

Big‐Data Analysis of Geometric Descriptors as Efficient Predictors of Energetic Stability in Nonplanar Polycyclic Aromatic Hydrocarbons

open access: yesJournal of Computational Chemistry, Volume 46, Issue 21, 05 August 2025.
Fast, geometry‐only descriptors—ΣDihedral, HOMA, and θRMSD—predict isomerization energies for peri‐condensed PAHs. The PAH Automated Property Scanner instantly converts an uploaded xyz file into a ΔE estimate, enabling large‐scale screening and design. ABSTRACT Accurate, efficient stability predictors are essential for understanding isomer formation in

Accurate and Efficient Description of Acidic Zeolites with Plane‐Wave Density Functional Theory Using Range‐Separated Hybrid Functionals

open access: yesChemPhysChem, Volume 26, Issue 15, August 4, 2025.
Range‐separated functionals, such as ωB97M‐D4, are shown to perform very well for reactions in acidic zeolites. Importantly, they work well with plane‐wave density functional theory and can thus be directly applied to periodic models at modest computational cost.

Multi‐Pathway Upconversion Emission in Symmetry‐Broken Nanocavities: Broadband Multiresonant Enhancement and Anti‐Correlated Interfacial Sensitivity

open access: yesAdvanced Functional Materials, Volume 35, Issue 35, August 28, 2025.
Symmetry‐broken plasmonic nanoantenna arrays achieve broadband multiresonant enhancement of second harmonic generation (SHG), third harmonic generation (THG), and upconversion photoluminescence (UCPL), under femtosecond laser excitation across the near‐infrared range (1000–1600 nm).
