  • Russian-Born Scientist Receives The 2023 Nobel Prize in Chemistry

    Moungi Bawendi, Louis Brus, and Alexei Ekimov won the 2023 Nobel Prize in Chemistry for their discovery and study of quantum dots. The awards ceremony was streamed live on the Nobel Assembly’s website on October 4. Below is a primer on quantum dots and their possible applications by ITMO researchers.


  • ITMO Researchers Create Perovskite Chess Set That Glows in the Dark

    For today’s International Chess Day, a research team from ITMO’s School of Physics and Engineering presents a unique device – a chess set with light-emitting pieces that contain perovskite. The energy is delivered wirelessly into each piece using a special transmitter embedded into the chessboard.


  • Picture of the Week: AgInS Quantum Dots in CaCO3 Calcite Phase

    These structures can become an alternative to semiconductor cadmium nanocrystals, which will allow using them as a transport system for drug delivery. They make it possible for substances to reach their target locations without affecting the cells, organs, and tissues that they shouldn’t.


  • Picture of the Week: Dendrites of Semiconductor Quantum Dots

    The photo was taken during a study aimed at increasing the efficiency of solar batteries.


  • One Summer and Three Schools: ITMO Master’s Student Wins Poster Session At Biophotonics Summer School

    Anastasia Lazareva has presented a report on the generation of reactive oxygen species with hybrid structures based on CdSe quantum dots and thermally annealed titanium butoxide. She received positive feedback from experts as well as offers to collaborate. 


  • Picture of the Week: ITMO Researchers' "Lightsaber"

    Well, it’s actually a demonstration of light distribution in waveguides with an active medium.


  • ITMO Graduate and UbiQD’s Senior Director of Physics Nikolay Makarov: A Scientist’s Interests Must Always Be In Flux

    Nikolay Makarov was a student at ITMO University in the late ‘90s to early ‘00s. In that time, his scientific interests shifted from programming to experimental physics. His work caught the attention of an American university, where he eventually got his PhD. Since then, Nikolay has lived in the US, having worked at various universities, research institutes, and even at the Los Alamos National Lab. Today, he works at UbiQD, a private manufacturer of quantum dots. ITMO.NEWS got in touch with Nikolay and learned about his story, why young scientists don’t stick around for long at American universities, and the prospects of US-Russian scientific collaboration.


  • 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.


  • Holographic Quantum Dot Laser in Progress

    How can we make a laser that will work effectively on low pump energy, be quite small and will allow dynamically changing the output radiation spectrum?  Vladimir Borisov, a  PhD  student at ITMO’s Department of Photonics and Optical Information Technologies, has won a grant of the Russian Foundation for Basic Research for creating just such a laser. One of the advantages of the new device is that the resonator is placed in the active laser medium, which simplifies the design while changing the resonator itself; it is created by  holographic  grating and uses quantum dots as photon sources.


  • Lasers&Photonics Congress: Quantum Dots and Topological Insulators

    The 18th Lasers&Photonics Congress has just kicked off in St. Petersburg; it includes several conferences, schools for young scientists and students, and an exhibition on laser and optoelectronic technologies. The main topics of the congress are: research into quantum dots and their practical application in lasers, a new concept of lasers based on topological insulators, as well as the possibilities offered by the European X-ray free-electron laser (XFEL), experiments on which began last autumn. These topics were discussed during the plenary presentations by the event’s main speakers. The congress is organized by ITMO University together with its partners.
