Physicists Discover What Happens Inside a Stable Vortex
Large vortices with characteristic spiral arms are often observed in the atmosphere and the ocean. Physicists from HSE University have explained how these structures form and why they retain their shape. The researchers found that velocities at points located along the same vortex arc remain correlated even over long distances. At the same time, this correlation weakens rapidly with increasing distance from the vortex centre. These differences help explain the formation of spiral arms and may improve models of atmospheric and oceanic currents. The findings have been published in Physical Review Fluids.

Antipova K. I., Puntus L. N., Lysenko K. A., D. M. Roitershtein

The reactions of sodium 2-(quinolyl-8-iminomethyl)phenolate with rare-earth element chlorides afford homoleptic mononuclear complexes [Ln{2-(8-quinolyl)N=CH–C6H4O}3] (Ln = La (I), Nd (II), Eu (III), and Tb (IV)) with the nonacoordinated rare-earth element ion. All synthesized complexes are similar in structure, and complexes II, III, and IV are isostructural (CIF files CCDC nos. 2124365 (I), 2124364 (II), 2124366 (III), and 2124367 (IV)). Compounds III and IV exhibit no luminescence, and characteristic luminescence in the near-IR range is observed for complex II. © 2022, Pleiades Publishing, Ltd.

Hall effect in electrolyte solutions: Self-consistent Debye–Hückel–Onsager theory
Budkov Y., Kalikin N., Journal of Chemical Physics 2026 Vol. 165 Article 064506
A self-consistent statistical-mechanical theory of the Hall effect in electrolyte solutions is developed by extending the self-consistent Debye–Hückel–Onsager (SCDHO) framework to crossed electric and magnetic fields. The theory incorporates non-local ionic charge distributions via Slater-type form factors, regularizing the Coulomb interaction at short range, and accounts for dielectric friction through ion-specific coefficients, employing experimental values ...

Long-range machine-learning potentials with environment-dependent charges enable predicting LO-TO splitting and dielectric constants
Korogod D., Shapeev A., Ivan S. Novikov, Physical Review B: Condensed Matter and Materials Physics 2026 Vol. 114 No. 2 Article 024104
We present two models with explicit long-range electrostatics in the form of Coulomb interactions. Both models include point charges depending on their local atomic environments, and the second model also conserves a total charge of an atomic system. We combine the proposed long-range models with the local moment tensor potential (MTP) and demonstrate that they ...

Incorporating Scientific Knowledge into Neural Network Density Functionals
Schneider M., Zaripov D., Dokin R. et al., Journal of Chemical Theory and Computation 2026 Vol. 22 No. 9 P. 4405–4414
Density functional theory (DFT) is the workhorse of modern reactions and materials modeling. While the exact functional remains unknown, many approximations to it have been constructed either by hand-crafting functional forms to satisfy exact constraints or by machine learning. In this work, we show how both of these approaches can be fused to build both ...

Obijiofor O., Novikov A., New Journal of Chemistry 2026 Vol. 50 No. 23 P. 9749–9768
Rational design of gold-based nanocarriers for neurotherapeutics requires atomic-scale understanding of drug-material interactions. Density functional theory calculations were performed to investigate levodopa (L-DOPA) adsorption on small gold clusters (Au2–Au4) with cationic, neutral, and anionic charges, with additional validation on a larger Au10 cluster using multiple low-energy isomers. Binding free energies (ΔGbind), charge transfer, and electronic descriptors ...

Band Gap Renormalization Drives Ultrafast Charge Separation and Slow Recombination in Covalently Functionalized Carbon Nanotubes: Nonadiabatic Molecular Dynamics Simulation
Chowdhury U., Mondal S., Dey S. et al., Journal of the american chemical society 2026 Vol. 148 No. 23 P. 24538–24550
Covalent functionalization offers a versatile platform to engineer carbon nanotube properties for optoelectronics applications. We demonstrate by atomistic quantum dynamics simulation that covalent functionalization can renormalize the CNT band gap, split the degenerate CNT band edge states, and strongly influence charge carrier separation and recombination dynamics. Open-ring CNT functionalization (O-CNT) largely retains the π-conjugation, whereas ...
