‘I Would Like My Research to Help Make the World a Calmer and Better Place
Whatever task Saraa Ali, Junior Research Fellow at the Laboratory of Methods for Big Data Analysis (LAMBDA) of the AI and Digital Science Institute (HSE Faculty of Computer Science), is working on, she thinks about how it can benefit people. She told the Young Scientists of HSE University project about her large family, diagnosing three-phase motors, and her dream of building a children’s home in her native country.

‘The Peak of Stupidity and ‘The Valley of Despair: HSE Economists Propose an Explanation for the Dunning–Kruger Effect
The Dunning–Kruger effect, which describes a sharp surge in self-confidence among beginners followed by an equally rapid decline as they gain experience, can be explained by the nature of the learning process and the acquisition of new knowledge. This conclusion was reached by Andrey Vorchik of the HSE Faculty of Economic Sciences together with independent researcher Murat Mamyshev. They developed a mathematical model of learning and demonstrated how subjective confidence is formed and changes as knowledge accumulates, as well as how teachers can reduce the ‘valley of despair’ experienced by learners.

‘I Like Self-Fulfilling Prophecies
Andrey Vorchik studies happiness, delivers popular science lectures, and believes that science should address social issues as well. In an interview for the Young Scientists of HSE University project, he spoke about how emotions influence decision-making, the Bermuda Triangle formed by the bathroom, refrigerator, and bed, and the ideal formula for education.

The influence of methoxy- group position on thermal stability and properties of novel isomeric 4-[(methoxy)phenoxy] phthalonitriles and phthalocyanine complexes based on them

Dyes and Pigments. 2023. Vol. 219. Article 111600.
Erzunov D., Rassolova A., Botnar A., Tonkova S., Rumyantsev R., Maizlish V., Aleksandriskii V., Vashurin A.

Isomeric 4-[(methoxy)phenoxy]phthadinitriles were obtained and characterized in this work. The compounds showed high thermal stability, which is directly related to their structure. These features were revealed and described using X-ray diffraction analysis. For m-substituted structures during packing, the largest contribution was found from intermolecular interactions of the π-stacking type between nitrile fragments. In the packing of o-substituted analogs, this type of interaction is not realized due to geometry, and additional stabilization is realized due to the appearance of three-center intermolecular bonds between the bridging oxygen atoms of one nitrile molecule and the hydrogen atom of the nitrile fragment of another molecule. Based on the obtained phthalonitriles, novel metal complexes with tetrakis-4-[4-(o-/m-/p-methoxy)phenoxy]phthalocyanine ligands were synthesized. For the substituted phthalocyaninates obtained the structure was characterized, the spectroscopic and luminescent properties were determined, as well as the influence of the position of the methoxy-group in the peripheral fragments on them. It is shown that, on the one hand, the position of the methoxyl-group has a significant effect on the values of the fluorescence quantum yields of the compounds, and, on the other hand, has almost no effect on their fluorescence lifetimes.

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 ...
