  • Researchers Present New Synthesis Method for Optically Active Carbon Nanodots

    One of the most remarkable carbon-based nanomaterials are luminescent carbon dots, the physical and chemical properties of which are easy to control. Thanks to their low toxicity, these particles are said to possess great potential in the fields of biology and medicine. Carbon dots are made from organic substances; if their precursor contains a chiral center, the resulting nanoparticles will be chiral, too. These particles have various application prospects, including in medical diagnostics. Researchers from ITMO University and St. Petersburg State University, in collaboration with their international colleagues, have developed a new way to synthesize such nanoparticles with stable optical properties.


  • Physicist Tatiana Orlova On New Materials for Soft Robotics and Working in Europe

    In 2007, Tatiana Orlova received her PhD in solid state and liquid crystals physics from the Institute of Physics of the Ukrainian National Academy of Sciences. Since then, she has collaborated with Strasbourg University and the University of Bordeaux in France, the University of Twente in the Netherlands, and the University of Southampton in England. Two years ago, she joined the ITMO Fellowship & Professorship program that brings together experts in different fields. In this interview, we asked Tatiana about her international experiences, the projects she is working on at ITMO, and the advice she’d give to young researchers. 


  • 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.


  • Chirality: The Property That Changes It All

    This year, specialists from ITMO's Modeling and Design of Nanostructures Laboratory published several articles on nanocrystal chirality in such renowned science journals as Optics Letters, Journal of Applied Physics and Scientific Reports. The article on the optical activity of chiral nanocrystals was highly praised by the Optical Society (OSA). So, why is chirality of nanocrystals and biomolecules so important? What methods do experts develop to separate hazardous substances from safe ones? Ivan Rukhlenko, head of Modeling and Design of Nanostructures Laboratory, and Nikita Teplyakov, his colleague, shared on the topic.
