Russian Scientists Pioneer Accurate Mathematical Description of Quantum Dicke Battery
Physicists at HSE University and NUST MISIS have formulated and solved equations for a quantum battery, a device capable of storing energy in the form of light. Their findings will facilitate precise calculations of the capacity, power, and duration required for optimal battery charging. Quantum batteries are expected to improve the performance of solar panels and electric vehicles, while also opening up new avenues for efficient energy transfer. The study has been published in Physical Review A.

Inverse Relationship Found between Propensity to Innovate and Academic Success

Inverse Relationship Found between Propensity to Innovate and Academic Success
Mariia Evdokimova and Anastasia Stepanova, employees of HSE University’s Faculty of Economic Sciences, studied the connection between students’ personal characteristics and their desire to create something new. The researchers have found that students’ propensity to innovate lowers their GPA. The results of the work were published in the preprint ‘Students’ Propensity to Innovate: Correlates, Determinants, and Impact on GPA.’

Cognitive Reappraisal of Negative Emotions Can Help Manage Stress

Cognitive Reappraisal of Negative Emotions Can Help Manage Stress
Researchers at the HSE International Laboratory of Social Neurobiology assessed the effectiveness of two strategies for regulating emotions: reappraisal and suppression. Having analysed data on the electrical activity of 60 individuals’ brains, the scientists discovered that both approaches put additional strain on the nervous system. It was also found that individuals who are prone to emotional contagion tend to be more effective in using reappraisal and managing negative emotions. The paper has been published in Experimental Brain Research.

WYF 2024 Participants Together with HSE Experts Assemble a Satellite Model Using Blockchain Technology

WYF 2024 Participants Together with HSE Experts Assemble a Satellite Model Using Blockchain Technology
Participants at the World Youth Festival, together with HSE University specialists, have developed a working model of a small spacecraft using blockchain technology. Future engineers aged 14-18 from Algeria, Serbia,  and Kyrgyzstan, as well as different regions of Russia took part in this project.

Scientists Devise Cheaper and Easier Method for Synthesising Layered Rare Earth Hydroxides—'Chemical Sandwiches’

Scientists Devise Cheaper and Easier Method for Synthesising Layered Rare Earth Hydroxides—'Chemical Sandwiches’
Researchers at HSE University and the RAS Kurnakov Institute of General and Inorganic Chemistry have developed a simplified and cost-effective method for synthesising layered rare earth hydroxides using propylene oxide. This reagent helps streamline the process and reduce its duration by several hours. In the future, this method is expected to facilitate the synthesis of various hydroxide-based hybrid materials, including photocatalysts for water purification and luminescent materials for solid-phase thermometers. The paper has been published in the Russian Journal of Inorganic Chemistry.

Scientists Model Turbulence at Atomic Level

Scientists Model Turbulence at Atomic Level
Scientists at HSE University and MIPT have developed a supercomputer-based method to model fluid flows at atomistic scales making it possible to describe the emergence of turbulence. The researchers used the supercomputers cHARISMa and Desmos to compute the flow of a fluid consisting of several hundred million atoms. This method is already being used to simulate the flow of liquid-metal lead coolant in a nuclear reactor. The paper has been published in The International Journal of High Performance Computing Applications.
