  • ITMO’s Monday Science Roundup #58

    It’s that time again – the time for our biweekly review of top reports from ITMO.NEWS. There’s plenty of ground to cover this week: we’ve got cutting-edge research by the Faculty of Physics, comprehensive explainers on AI and hacking courtesy of top experts, and two great new Bachelor’s and Master’s programs for ambitious students. Have a look!


  • Researchers at ITMO Create More Durable Blue Perovskite Diodes for RGB Screens

    ITMO University scientists have found a new way of creating blue-emitting perovskite nanocrystals that makes them more stable, while their light doesn’t change to green overtime, unlike existing counterparts. Such light sources can serve as a platform for manufacturing of RGB displays for TVs and phones with a higher quality color rendering, which will also be cheaper than their analogs. The results of the project are described in a paper published in  ACS Applied Materials & Interfaces.


  • Cheap and Simple Method of Detection of Harmful Gases Suggested by ITMO Researchers

    Researchers from ITMO and North Ossetian State University have suggested a brand-new cheap and highly sensitive method of detecting hazardous hydrogen halides that are toxic for humans. The new perovskite nanolaser-based method is able to detect dangerous concentrations of various substances that can vary in the range of 5-500 molecules per a million of air molecules. Their suggestion may provide the basis for highly sensitive compact gas leak detectors for the food and chemical industries.


  • ITMO’s Monday Science Roundup #19

    Winter’s round the corner, so make yourself cozy and sit down for a quick yet enlightening read with our bi-weekly digest of ITMO’s science breakthroughs and developments. Today, you’ll hear about new technologies in advanced materials, particle physics, and optical computing – as well as a new educational course and our students’ successes.


  • ITMO PhD Student ‪Pavel Tonkaev‬ on His Path to Science and Applied Nanophotonics

    Pavel Tonkaev started his Master’s at ITMO University in 2017 after graduating from Peter the Great St. Petersburg Polytechnic University (SPbPU). Since his second year here, Pavel has been studying perovskite materials in nanophotonics and optoelectronics. Current studies suggest that these materials may not only become the future of solar energy but also set the stage for various other technologies, from the creation of sensitive photodetectors to the study of living cells. In this article, Pavel talks about how to get into research in the second year of your Bachelor's, how his discoveries can help people in the future, and why scientists shouldn’t stick to one perspective.


  • ITMO Researchers Create Nanoparticle Paste To Maximize Perovskite Solar Cell Efficiency

    An international team of researchers from ITMO’s School of Physics and Engineering and Tor Vergata University of Rome found a way to increase the efficiency of perovskite-based solar cells. The project was supported by a Russian Science Foundation grant and its results were described in a paper published in Nano Energy. 


  • 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.


  • Cutting Perovskite: Scientists Succeed in Shaping Microscopic Monocrystals Without Loss of Quality

    A research team that includes staff members of ITMO University has suggested a new method of processing miniature perovskite fragments. The method is cheap and makes it possible to fashion microcrystals into desired shapes for use in production of lenses and other optoelectronic elements. This will help bring about the material’s widespread adoption within the industry. A paper on the research was published in Laser & Photonics Reviews.


  • ITMO Fellowship Stories: Daniel Sapori on His Decision to Pursue Science in Russia

    Daniel Sapori came from France to St. Petersburg to do applied research on perovskite solar cells. Now, he works at ITMO’s Laboratory of Hybrid Nanophotonics and Optoelectronics under the supervision of Sergey Makarov.


  • Picture of the Week: Perovskite Crystals in Textile
