New Functional Nano-Materials for Nanotechnology, Bio-Medicine and Energy
Dr. Victor Koledov

In recent decades, new functional solid state materials have attracted much attention of material scientists, physicists and engineers. The physical basement of the unique functional properties of the new materials is often associated with phase transitions that manifest themselves in a solid state: magnetic, structural, superconducting ones. The resulting “giant” effects of the striking controlled change of size, shape, entropy, conductivity etc. in these materials, under action of heating/cooling, stress and/or magnetic field, exceed by the orders of magnitude the usual effects of magnetostriction, thermal expansion, etc. These effects provide new opportunities for next step engineering, microsystem technology, biomedical technology and alternative energy. Several new kinds of the solid state functional materials with phase transitions will be described in the lecture, including magnetic and non-magnetic shape memory alloys, magnetocaloric materials based on Heusler alloys and rare Earth elements. The devices based on them and their prospective applications will also be detailed. Particularly, the new technology of the composite shape memory mechanical nano-tools with record small dimensions and high frequency of operation will be described. New room temperature applications of the magnetocaloric effect and magnetic functional materials for solid state refrigerators and heat pumps will be outlined. The new ideas of the economical high magnetic field generation for electrical engineering, super high speed vacuum magnetic levitating transportat and medical diagnostics will be discussed. The 10 years’ experience of the new shape memory dental implant system based on nanostructural shape memory materials for treatment of the patients with severe dental diseases will also be reported.

The main distinctive feature of the scientific school, to which belongs, and which develops V. Koledov is combination of fundamental research in the fields of magnetism, physics of phase transitions and new functional materials, consistently focused on important topics of applied problems with the continuous training of graduate students and young scientists from leading universities of Russia such as: MIPT, Moscow State University, Bauman MSTU, MEPI, MISIS, and others. The scientific school is based on the laboratory of physics of magnetic phenomena of Kotelnikov IRE RAS, which is currently headed by professor Vladimir G. Shavrov. This school now goes far beyond the boundaries of the Institute and Moscow. It has strong scientific relations, especially in Chelyabinsk and other cities of the Urals (Ufa, Ekaterinburg), as well as such cities of Russia, as Tver, Syktyvkar, Makhachkala, etc. To date, it has strong links, works on joint projects, published articles and patents in collaboration with the scientists from other countries: USA, Japan, Germany, India, China, Spain, Italy, Ukraine, Australia Belarus etc. The scientific and educational activities of V. Koledov in recent years are concentrated in the Scientific-Research Educational Center (REC) 'Magnetoelectronics and nanophysics', which was created in 2008 in Kotelnikov IRE RAS under leadership of professor V.G. Sharov. REC brings together faculties and students from leading universities, which are taking pre-graduation practice and prepare their bachelor, master, PhD, and Dr of Science theses. The basis of learning and research activities of this largely informal group, is an integrated approach to scientific work: from basic research through all the technological, theoretical and practical developments to the solution of applied problems in priority areas of Russian and World science and engineering, in particular nanotechnology, microsystems technology, medicine and alternative energy . V.V. Koledov in recent years has participated in 28 basic, applied and innovative projects (including 9 as the Principal Investigator), supported by various Russian and foreign foundations and organizations. They are listed in Annex 1. One of this project unexpectedly have led to the invention of the smallest in the world nanotools with shape memory effect which are currently proved to manipulate with CNTs, stacks of grapheme layers, nanoparticles, bionanofibers and so on. This gave the idea of the Project slogan: “Uralskiy Levsha”. Levsha is well recognized in Russia hero of the fantastic story by XIX century Russian writer Pavel Bazhov. Levsha has surprisingly versed the mechanical flea, created by some unique English master.
