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.

This new model accounts for a wide range of ion-electrode interactions and predicts a device's ability to store electric charge. The model's theoretical predictions align with the experimental results. Data on the behaviour of the electric double layer (EDL) can aid in the development of more efficient supercapacitors for portable electronics and electric vehicles. The study has been published in ChemPhysChem.

A team of researchers from HSE MIEM joined colleagues from the Institute of Non-Classical Chemistry in Leipzig to develop a theoretical model of a polymeric ionic liquid on a charged conductive electrode. They used approaches from polymer physics and theoretical electrochemistry to demonstrate the difference in the behaviour of electrical differential capacitance of polymeric and ordinary ionic liquids for the first time. The results of the study were published in Physical Chemistry Chemical Physics.

Researchers from HSE MIEM and the Institute of Non-Classical Chemistry in Leipzig have proposed a new theoretical model of supercapacitors that takes into account the properties of a cation, which considerably impacts the electric differential capacitance of supercapacitors. This is the first publication of its kind in electrochemistry. The authors believe that the model will allow engineers to create more powerful energy sources in the future. The results of the study were published in The Journal of Physical Chemistry C. The study was completed with support from a grant by RSF.

Russian scientists have proposed a theory of phase transformation in polymer gels. It explains the mechanisms of the dramatic reduction in volume of zwitterionic hydrogels when they are cooled. The results are published in the journal Chemical Communications (ChemComm).

The paper by Yury Budkov, Professor at HSE MIEM School of Applied Mathematics, co-authored with Andrey Kolesnikov from Leipzig University, was initially published by a Russian journal, Polymer Science. Its English version was published by SpringerLink, where it generated considerable interest among visitors.

This year, the new Master's programme ‘Supercomputer Simulations in Science and Engineering’ will be launched at MIEM HSE. Graduates will be experts in the interdisciplinary field of computer technology, natural sciences and engineering sciences.

On August 31 – September 2, 2016, a conference on ‘The Future of Chemical Physics’, organized by the Journal of Chemical Physics, was held in Oxford, England.
