  • ITMO Researchers Create Model to Demonstrate What Happens During Microbiota Transplantation Genome-Wise

    Fecal microbiota transplantation (FMT) has been successfully used in treating metabolic and intestinal diseases. Even though the procedure shows high effectiveness, its mechanism remains unclear. To that end, scientists from ITMO University and the Federal Research and Clinical Center of Physical-Chemical Medicine (Russian Federal Medical Biological Agency) carried out an extensive study on post-FMT patients, during which they figured out how the intestinal microbiota changes under FMT and how its composition correlates with donor microbiota.


  • ITMO Scientists Enhance Multiphoton Processes in Perovskite Metasurfaces

    Researchers placed a polymer on a thin perovskite film and, using lithography, created a metasurface consisting of prolonged parallelepipeds. In the future, this will help create highly efficient visualizers for infrared radiation.


  • ITMO Scientists Propose Multi-Use System for Real-Time Temperature Monitoring in Living Cells

    The researchers from ITMO’s Faculty of Physics have created a multifunctional system for drug delivery capable of monitoring temperature inside living cells in real-time. Read on to learn what scientists need these measurements for and how they can be taken at the nanoscale.


  • Scientists Develop Compact Nanolaser with Unique Properties

    A team of researchers from the ITMO University’s School of Physics and Engineering, the Nonlinear Physics Center at the Australian National University (ANU), and Korea University has developed a compact nanolaser based on a photonic crystal waveguide with super-high efficiency. The device is a photonic structure and is notable for its small size compared to its counterparts. An article about this device was published in Nature Communications.


  • International Team Develop Non-Radiating Electromagnetic Source

    The proposed structure allows to generate electromagnetic fields without dissipating any energy into the surrounding environment. This type of electromagnetic source will pave the way for technological breakthroughs, such as highly efficient wireless power transfer systems, high-precision sensors, and RFID technology.


  • ITMO Researchers Introduce New Method for Magnetization Switching

    Scientists Andrew Kudlis, Ivan Shelykh, and Ivan Iorsh from ITMO’s School of Physics and Engineering have proposed an innovative method for ultrafast magnetization switching in layered magnetic structures. The developed technique makes it possible to efficiently control memory cells and break the ground for fully optical methods of recording information in 2D materials. The article detailing the results of the study is published in Physical Review B, a peer-reviewed journal of the American Physical Society.


  • ITMO Researchers Find a Way to Control Localized Light

    Scientists from ITMO University, the National University of Colombia, and the University of Siena have developed a metasurface with a unique structure and properties. The proposed solution makes it possible to generate surface waves with new characteristics, transfer them from point to point while maintaining their initial polarization, and therefore improve information communication. The relevant article is published in Physical Review X.


  • How To Teach a Computer To Interpret Text

    A team of scientists from ITMO University has created a model for an algorithm that can analyze the meaning of texts. It differs from regular neural networks because it not only takes into account word usage frequency but also introduces a category of subjective text perception. Read on to find out what it means for the future of artificial intelligence and how quantum theory is of help here.


  • Molecular Building Blocks: Scientists Demonstrate Controlled Melamine Cyanurate Nucleation

    The conducted experiments may potentially be applied in creating capsules for targeted drug delivery. As the structure of melamine cyanurate is similar to that of DNA, a thorough study of its formation can bring researchers closer towards artificial DNA.


  • ITMO Physicists Discover New Physical Effect

    The scientists called it the anomalous exciton Hall effect. It occurs when a laser affects a semiconductor plate in the presence of a magnetic field. This phenomenon can be potentially used for studying exciton quasiparticles. The research is published in Physical Review Letters.
