‘Balkan Hospitality Opens Doors: Studying Dialects on the Verge of Extinction
You cannot study spoken dialects from books. Instead, you need to go to a village, seek out its elders, and earn the trust of local residents before you can record hours of spontaneous stories. This is how Natalia Muravleva, Associate Professor at the Faculty of Humanities, conducts her research. Her internship in Serbia continued her long-standing study of dialects spoken by Macedonian settlers. In this interview, she discusses how diaspora cultural centres help researchers reach informants, why native speakers need to be interviewed only in their own language (otherwise, as she puts it, they may 'break'), and how a single field season helped her finalise her monograph. She also shares warm memories of autumn in Belgrade and of colleagues with whom grammar can be discussed in three languages at once.

Scientists Train Neural Network to Generate Process Plans from 3D Models
Researchers at the HSE FCS AI and Digital Science Institute have developed CAD2TechSpec, a framework that converts 3D models of mechanical parts into machining process plans—step-by-step instructions for machine tools. The solution aims to reduce the time required for the design and preparation of technical process documentation in mechanical engineering, aircraft manufacturing, and other high-tech industries. The study findings have been published in PeerJ Computer Science.

Biologists Discover 'Molecular Fingerprint' of Preeclampsia
Researchers at HSE University employed a new method to model hypoxia in placental cells during pregnancies complicated by preeclampsia and identified molecular markers of tissue hypoxia. Since hypoxia is one of the key mechanisms underlying preeclampsia, these findings are important for a more accurate and timely diagnosis of the disease and for the development of effective treatment methods. The paper has been published in Placenta.

Polymorphism and Peroxomorphism in Peroxosolvates of Zwitterionic Sulfonic Acids: Features of H-Bonding and Crystal Packing

Crystal Growth & Design. 2023. Vol. 23. No. 10. P. 7252–7265.
Stanislav I. Bezzubov, Yakushev I., Medvedev A., Prikhodchenko P., Churakov A.

A novel class of crystalline hydrogen peroxide adducts, peroxosolvates of zwitterionic sulfonic acids C2H7NO3S·H2O2 (1), p-C6H7NO3S·H2O2 (2), p-C6H7NO3S·0.5(H2O2) (3), m-C6H7NO3S·H2O2 (4), o-C6H7NO3S·H2O2 (5), C5H5NO3S·H2O2 (6), C12H8N2O3S·H2O2 (7), C8H17NO3S·2(H2O2) (8), C10H9NO4S·1.25(H2O2)·0.25(H2O) (9), C10H9NO4S·H2O2 (10), and C10H9NO4S·0.94(H2O2)·0.06(H2O) (11), were prepared from highly concentrated hydrogen peroxide, and their structures were determined by X-ray crystallography. In all compounds, first observed charge-assisted HOOH···–O3S– and well-known NH+···–O3S– hydrogen bonds played a predominant role in crystal packing. The influence of H-bonding on valent S–O distances was discovered. A comparative analysis of the HOOH···O hydrogen bond strength was performed. Polymorphism and temperature-induced phase transition for organic peroxosolvates were observed for the first time. A noticeable temperature dependence of hydrogen peroxide O–O distance was found for compound 8.

Stress tensor of inhomogeneous flexible polymer chain solutions beyond the ground-state dominance approximation
Budkov Y., Journal of Chemical Physics 2026 Vol. 165 No. 9 Article 094902
We derive the stress tensor of a flexible polymer solution within the Gaussian-chain self-consistent field theory (SCFT) without invoking the ground-state dominance (GSD) approximation. Starting from a covariant formulation of the single-chain partition function in a background metric, we obtain the symmetric stress tensor expressed through the full Edwards propagators. The result contains the local ...

Understanding the electric double layer at electrode–electrolyte interfaces, Part III: crystallographic-face dependence of silver capacitance in aqueous NaF solutions
Mazur D., Petr E. Brandyshev, Doronin S. et al., Electrochimica Acta 2026 Vol. 577 Article 149729
The electric double layer (EDL) at a single-crystal metal surface is controlled not only by the electrolyte composition and the electrode potential, but also by the atomic structure of the surface itself. This makes the Ag(hkl)/NaF interface a stringent test for continuum theories of the EDL. In the third part of our series, we examine ...

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 ...

Charge-controlled binding, alloy synergy, and the copper anomaly in Au–Ag–Cu dimers to clusters: DFT-derived design rules for targeted drug delivery
Novikov A., New Journal of Chemistry 2026 Vol. 50 P. 13931–13957
The rational design of coinage metal nanocarriers requires a mechanistic understanding of metal-drug binding and predictive descriptors that translate molecular interactions into design rules. Using DFT (B3LYP-D3BJ/def2-TZVP, SMD water), we systematically investigated the binding of 5-fluorouracil (5-FU) and levodopa (l-DOPA) to neutral and cationic homo- and heteronuclear dimers of Au, Ag, and Cu (Au2, Ag2, ...

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 ...

Developing efficient photoactive materials from bio-derived resources is vital yet challenging for achieving effective water splitting performance. In this work, nano carbon dots (CDs) of zero-dimensional (0D) were synthesized from papaya peel through a simple and eco-friendly process and subsequently anchored onto the two-dimensional (2D) layered structure of graphitic carbon nitride (g-C3N4, GCN) at various ...

Generative adversarial networks (GANs), first published in 2014, are among the most important concepts in modern artificial intelligence (AI). Bridging deep learning and game theory, GANs are used to generate or “imagine” new objects with desired properties. Since 2016, multiple GANs with reinforcement learning (RL) have been successfully applied in pharmacology for de novo molecular design. Those ...

(2-Fluoroallyl)boration of Ketones with (2-Fluoroallyl)boronates
Novikov M., Bobrova A., Mezentsev I. et al., The Journal of Organic Chemistry 2020 Vol. 85 No. 10 P. 6295–6308
Efficient routes toward activation of gem-chlorofluorocyclopropane-derived (2-fluoroallyl)boronates for allylboration of various ketones including functionalized and low-reactive ones were developed. Increasing the boron electrophilicity by the transformation of a boronate moiety into a borinic ester with nBuLi/trifluoroacetic anhydride (TFAA) makes (2-fluoroallyl)boration of acetyl arenes/hetarenes and aliphatic ketones possible with high diastereoselectivity. For low-reactive or sterically hindered ketones (e.g., ...
