  • ITMO University Professor Joins Nanomaterials as Special Issue's Guest Editor

    Today, physicists, chemists, and materials scientists around the globe seem to have immersed themselves in the world of nanostructures, which promises us materials for unique lasers, remarkably efficient solar cells, quantum computers, and high-resolution monitors. But how efficiently can modern physics explain all the processes taking place in the nanoworld? Do theoretical and experimental physicists have enough reliable and simple tools to solve fundamental problems concerning nanomaterials? These questions are the subject of the special issue of the international peer-reviewed journal Nanomaterials". Its guest editor is Anatoly Fedorov, the head of the International Research and Education Center for Physics of Nanostructures and a professor at ITMO University.


  • Scientists Studied Hybrid Nanoparticles Capable of Generating Broadband Radiation

    An international group of scientists from Russia, Germany and France, including those from ITMO University, conducted a large research at the intersection of materials science and photonics. The research is dedicated to the study of a hybrid nanostructure, a plasmonic golden sponge (Au), the pores of which are filled with crystalline silicon (Si). The peculiarity of this material is that when excited by a laser beam, nanostructures generate broadband radiation which covers the visible range of the spectrum and partially the near-infrared range. The hybrid nanostructure can be used in broadband near-field microscopy. The results of the research and its application prospects have been published in the Nanoscale journal.


  • Serious Science: How School Students Create Projects at Sirius and Develop Them Under the Guidance of ITMO

    This summer, dozens of Russian school students came to Sirius to work on projects in 12 different tracks, from Nanotechnology to Cognitive Studies, New Materials and Smart cities. Researchers from ITMO University’s Faculty of Physics and Engineering participated in the program as mentors and project developers. With their guidance, the students developed breakthrough nanostructured antibacterial surfaces and a metalens for focusing Wi-Fi radiation. To continue working on their projects, the students came to ITMO where they not only attended lectures but also got a chance to visit ITMO’s many laboratories and work on real-life lab equipment. Read on to learn more about their project results and plans for the future. 


  • ITMO Researchers Describe Carbon Dot Structure, Discover Red Emission Amplification Method

    Fluorescent carbon nanoparticles, also known as carbon dots, were first described in the early ‘00s. But even today, scientists around the globe still have not reached a consensus on their inner structure and emission process. Carbon dots have a great deal of potential applications due to their biocompatibility with the human body and the ease and low cost of their production as compared to semiconductor quantum dots. Researchers from ITMO University have published two research papers in which they put forth their answers to the burning questions about carbon dots.


  • Scientists Propose a Fully Optical Method for Near-Field Reshaping and Enhancement in Hybrid Metal-Dielectric Oligomers

    Scientists from ITMO University in collaboration with researchers from Saint Petersburg Academic University have developed a fully optical method that allows to reconfigure the properties of hybrid metal-dielectric oligomers in the near field. This offers a simpler and cheaper alternative to the existing methods of working with such structures. The use of metal-dielectric oligomers has a lot of potential for developing new data recording devices, as well as in sensor science. The research was published in Laser & Photonics Reviews.
