A supercapacitor is a device capable of rapidly storing and releasing a significant amount of energy within a matter of seconds. It consists of metal electrodes immersed in an electrolyte solution. In their model, MIEM HSE scientists substituted the conventional low-molecular-weight electrolyte with a polyelectrolyte, resulting in an unexpected and adverse physical phenomenon: supercapacitors experience a reduction in capacitance when the pore size of the electrode is below 1 nm. By carefully selecting optimal conditions for polyelectrolytes, it becomes possible to develop supercapacitors that are not only more robust but also more efficient in their performance. The study has been published in Physical Review E.

On May 19, the annual Mental Health Spring festival dedicated to psychological health took place in the atrium of HSE University on Pokrovsky Bulvar. The event was organised by the HSE Centre for Psychological Counselling and the ‘Training School’ student organisation.

Students of the English-language master's programme ‘Population and Development’ study issues related to the impact of demographic processes on a country's social development, as well as learn how to develop the relevant administrative measures to ensure sustainable development. Below, the programme's academic supervisor and international students provide more information about the programme and studies in Moscow.

Economists and sociologists who study alcohol consumption patterns often link them to people's living conditions and human capital such as education, work experience, and knowledge. Researchers of the HSE Laboratory for Labour Market Studies and the HSE Laboratory for Studies in Economic Sociology have found that non-cognitive skills developed in childhood and adolescence can have a major effect on the likelihood of alcohol abuse later in life and can diminish the role of education in this respect. The paper has been published in the Journal of Comparative Economics.

After studying the brain scans of 13 Russian cosmonauts who participated in space missions to the ISS from 2014 to 2020, scientists discovered that prolonged exposure to microgravity had an impact on the connectivity of the brain structures responsible for adapting to unfamiliar conditions. The study revealed that these connections may not always return to their original state after the flight. The paper has been published in Communications Biology.

On May 18, 2023, HSE University and the University of Technology Malaysia signed an agreement on scientific and educational cooperation at the XIV International Economic Forum ‘Russia—Islamic World: KazanForum’. The agreement was signed by HSE Rector Nikita Anisimov and UTM Vice Chancellor Ahmad Fauzi bin Ismail.

Researchers at HSE University in Perm have used electroencephalography (EEG) to determine that consumers are willing to pay 10% more for chocolate when they know it to be a premium product. On the other hand, if consumers are aware that a chocolate product is inexpensive, their willingness to pay decreases by 13%. On average, men are willing to pay 8.8 monetary units more for chocolate than women, and men's willingness to pay decreases by 0.3 monetary units with each additional year of age. The study has been published in Food Quality and Preference.

Neural network generative models have achieved impressive results in recent years, but researchers are still working on increasing their efficiency. Researchers from the HSE Faculty of Computer Science and AIRI have managed to optimize the finetuning of the StyleGAN2 neural network, which creates realistic images, to new domains, reducing the number of trained parameters by four orders of magnitude. At the same time, the quality of the obtained images remained high. The results of this work were presented at the NeurIPS 2022 conference.
