  • Russian Participants of European XFEL Observe and Document Never-Before-Seen Effect

    A team of ITMO University specialists and their German colleagues have successfully used the world’s largest free-electron X-ray laser to conduct an experiment on ultrafast demagnetization of ferromagnetic material using femtosecond IR excitation. While studying the dynamics of this process, the scientists had discovered a new type of X-ray scattering in ferromagnetic material, which occurs immediately after the laser pulse and lasts for some 100 picoseconds. Their findings were recently presented at the European XFEL Users’ Meeting in Hamburg, which brought together over 1,300 participants from 30 countries. ITMO.NEWS got in touch with Igor Pronin, the head of this project, who presented a plenary report on the study during the event.


  • What Cells Do When They Can’t Breathe

    Can cells measure the amount of oxygen around them? And why do they need it? How do they react to the changing conditions? This evasive mechanism of an animal cell had been in the dark for a very long time. It was the work of William G. Kaelin Jr, Sir Peter J. Ratcliffe and Gregg L. Semenza that finally shed light on this mechanism, earning them the 2019 Nobel Prize in Medicine or Physiology. Ekaterina Umnyakova, a senior researcher at the Institute of Experimental Medicine, explained what this discovery means for modern science, and especially for cancer treatment research. Her lecture took place at the Lermontov Central Library within the framework of the “Nobel Prize in the Open Living Room 2019” project. 


  • Russian Physicist Alexey Melnikov Awarded the Prestigious Cozzarelli Prize

    The annual Cozzarelli Prize acknowledges papers that reflect scientific excellence and originality. Among the 2018 Cozzarelli Prize recipients in the field of physics and mathematics is Russian physicist Alexey Melnikov. His research focuses on quantum machine learning technologies, as well as the development of new machine intelligence methods. The researcher works on a range of projects at the University of Basel (Switzerland), ITMO University, and the Valiev Institute of Physics and Technology of Russian Academy of Sciences in Moscow.


  • Transcending Humanity: Evolution of Technological Art

    Last week, the first FUTURE ART festival was held in St. Petersburg. The event explored the cutting-edge sphere of BioArt, an Art&Science current encompassing the synthesis of artistic, scientific, creative, and technological methods of contemporary art-making. BioArt adherents work with live materials and organic processes. In her FUTURE ART lecture, art expert and head of ITMO’s Art & Science Center Anastasiia Yarmosh talked about how the technological art changed over the years, in which direction it is now heading, and what questions it deals with today.


  • New Nanoobject Construction Method Opens Road to Complex Optics

    ITMO University scientists have developed a new approach to nanoobject construction, one that provides the opportunity to study and predict how deformations and defects in the crystal lattice affect the optical properties of semiconductor nanocrystals. This model allows them to calculate both the linear and non-linear optical properties of various nanoobjects such as: nanorolls, nanorods, nanoplates and others. The method can be used to create optical materials and devices with new functionalities with uses in drug delivery, chiral exciton-based devices and chiral catalysis devices, and areas such as biosensing and spintronics. Results of this research were published in Nano Letters and used in the writing of other articles in ACS Nano.


  • First Russian Li-Fi Network Launched at ITMO University

    The first light-operated data transmission network in Russia was launched by ITMO University’s Department of Light Technologies and Optoelectronics. The new format, known as Li-Fi, may become an effective alternative to Wi-Fi. It uses optical signals instead of radio waves, and, in fact, transmits data hundreds of times faster than traditional wireless networking. A speed of 50 Mbps was reached in the ITMO University laboratory, which is comparable, and even superior, to a regular Wi-Fi connection. Li-Fi communication channels are considered to provide better security. They may also be used in Wi-Fi “dead-zones”: operating rooms, airplanes, and in other conditions requiring minimization of radio interference.
