Scientists at HSE University Devise More Accurate Method for Predicting the Electrical Conductivity of Electrolyte Solutions
Researchers at HSE MIEM have developed a model for calculating the electrical conductivity of aqueous electrolyte solutions; for the first time, it considers the spatial distribution of ion charges instead of assuming their localisation at a single point. The model remains effective even at high electrolyte concentrations and across a wide temperature range. This breakthrough will contribute to the development of more efficient batteries and enable the calculation of electrical conductivity without the need for experimental testing. The study has been published in the Journal of Chemical Physics.
Russian Scientists Integrate Microdisk Laser and Waveguide on a Single Substrate
A group of Russian scientists led by Professor Natalia Kryzhanovskaya at HSE Campus in St Petersburg has been researching microdisk lasers with an active region based on arsenide quantum dots. For the first time, researchers have successfully developed a microdisk laser coupled with an optical waveguide and a photodetector on a single substrate. This design enables the implementation of a basic photonic circuit on the same substrate as the radiation source (microlaser). In the future, this will help speed up data transfer and reduce equipment weight without compromising quality. The study results have been published in Semiconductors.
Considering News Background Can Improve GDP Projections in Periods of Instability
The accuracy of Russian GDP forecasts during periods of instability improves in 45% of cases when news reports are taken into account. However, during more stable periods, this advantage nearly disappears. News provides an up-to-date view of the economy and enables quicker responses to emerging challenges. This was revealed by an analysis of over 500,000 news reports conducted by Ivan Stankevich and Natalia Makeeva of the HSE Faculty of Economic Sciences (FES), and Nikita Lyubaykin. The study results have been published in Voprosy Ekonomiki.
Scientists Disprove Bunkbed Conjecture
Mathematicians from Russia, including two HSE graduates, have disproven a well-known mathematical conjecture that, despite lacking solid proof, had been considered valid for 40 years. The ‘Bunkbed Conjecture’ belongs to percolation theory—a branch of mathematics that studies the formation of connected structures in independent environments.
Men Behind the Wheel: Three Times More Violations and Accidents than Women
Men are three times more likely than women to commit traffic violations while driving and to be involved in accidents. Moreover, they are more likely to create situations on the road that are highly dangerous to others. Men are also twice as likely to drive under the influence and nearly one-third more likely to receive a prison sentence for reckless driving. Perhaps it comes down to cultural norms and the different attitudes men and women have toward driving. These are the conclusions reached by Anton Kazun, Assistant Professor at the HSE Faculty of Economic Sciences, and Research Assistant Mikhail Belov.
HSE Scientists Discover How to Predict Charitable Behaviour Through Physiological Reactions
Researchers at the HSE Institute for Cognitive Neuroscience have investigated how the emotional impact of advertising affects the amount people willing to donate to support animal welfare. To accomplish this, the researchers measured physiological responses such as heart rate, electrodermal activity, and facial expressions in individuals viewing various photos of dogs. The findings indicate that willingness to donate is most accurately predicted by heart rate and facial muscle activation. The study has been published in Social Psychology.
Between Natural Risks and Tourism Development: How the Life of Local Communities in the Indian Himalayas Is Changing
In 2024, scientists from HSE University-St Petersburg went on two expeditions to the Indian Himalayas. The second trip finished at the beginning of October, and now, the researchers are summing up its results. Read on to find out what new things they learned about the state of Himachal Pradesh, why floods and earthquakes have increased dramatically, and how local citizens adapt to the growth of tourism in the region.
Humans, Bots, and Digital Twins: Year-End Results of the Strategic Project 'Human Brain Resilience'
HSE University hosted a joint research seminar to review the 2024 results of the Strategic Project 'Human Brain Resilience: Neurocognitive Technologies for Adaptation, Learning, Development and Rehabilitation in a Changing Environment.' The event showcased the progress and outcomes of fundamental and applied projects focused on developing technologies for neurodiagnostics, neuroadaptation, and neurorehabilitation—collectively known as 3N technologies. The objective is to develop tools that can help prevent neurogenic and psychiatric disorders or alleviate their consequences.
First Successful Attempt in 55 years: Physicists in Russia and Germany Confirm 1969 Experiment Results
A team of researchers, with the participation of physicists from HSE University, replicated the 1969 experiment on superconductivity and its properties. The scientists induced superconductivity by deliberately deteriorating the interfaces between the layers of superconductors and ferromagnets in the system, resulting in better performance of spin valves compared to the classical version, where the interfaces between the layers are ideal. This approach could lead to the development of more efficient devices for data storage and computing. The study findings have been published in the Beilstein Journal of Nanotechnology.
HSE University-St Petersburg Holds International Expert Day on Social Entrepreneurship
On November 29, the campus hosted the Expert Day of the HSE University-St Petersburg and University of Technology Malaysia mirror laboratory. The official partner of the event was the Our Future foundation.
