``Physicochemical and Applied Problems of Magnetic Disperse Nanosystems''

Stavropol, Russia, September 2017

PREFACE

The physics of magnetic dispersed nanosystems is a modern, dynamically developing field of fundamental and applied research. The interest to this scientific field is determined by the possibility to control the properties and behavior of liquid magnetically soft and composite materials, such as magnetic colloids, magnetorheological suspensions, ferrogels, magnetic elastomers, etc. by a remote magnetic field. Such materials and media have been found to be promising in technological and biomedicine applications.

The All-Russian conferences on magnetic dispersed nanosystems (magnetic fluids) have a long history. Since 1977, the conferences have been held in Ivanovo, Perm, and Stavropol. The international scientific conference on Physico-Chemical and Applied Problems of Magnetic Disperse Nanosystems organized by the North Caucasus Federal University is traditionally held once every two years since 2007 in Stavropol. The conferences sum up the results of the topical studies on magnetic nanosystems and materials, discuss the most important and promising trends in this field.

The All-Russian scientific conferences on magnetic nanosystems by the North Caucasus Federal University emphasize the fact that the University is a recognized scientific centre in the field of magnetic nanosystems in Russia and has a notable position in the world scientific community. The scientific school of the physics of magnetic dispersed nanosystems in Stavropol exists and has been actively developing since the mid-1970's. V.V. Chekanov established a laboratory of magnetic fluids at the Chair of General Physics, which based the school foundation in 1977. The investigations performed there are focused on the study of structurally-kinetic, magnetic and optical properties of magnetic nanosystems. The scientific school has two research laboratories equipped with modern devices and is aimed at comprehensive studies of liquid magnetizing media, magnetic dispersed nanosystems and new composite magnetic nanomaterials. The scientific studies of the school are often supported by grants from different funds and organizations, including the Russian Foundation for Basic Research, the Council for Grants of the President of the Russian Federation, the programs of the Ministry of Education and Science, Human Capital Foundation, the fund for assistance to innovations.

The 6th All-Russian Scientific Conference held on September 6--9, 2017 in Stavropol addressed the fundamental and applied problems of disperse nanosystems, including physical-chemical problems of synthesis, and discussed the results of the investigations of magnetic, electric, optical, thermo-physical properties, micro-structural characteristics, magnetohydrodynamic problems, heat/mass transfer, convection and waves, the application of magnetic disperse nanosystems in technical engineering and biomedicine. The Conference program included plenary sessions, section meetings, round tables and excursions. More than 30 reports were presented at the conference; more than 40 participants attended the conference. After thorough peer-reviewing, 30 reports (papers) have been selected to be published in a Special issue of the international scientific Journal Magnetohydrodynamics.

The Conference Organizing Committee is grateful to the colleagues, who participated in the preparation of this issue and who have greatly contributed to the process of selection and reviewing of the submitted papers.
