• Finding Nanoparticles: ITMO Scientists Propose New Method for Discovering Nanomaterials With Desired Properties

  Researchers from ITMO’s ChemBio Cluster have devised an algorithm that can automatically detect the properties of nanoparticles, including their size, shape, and surface structure, based on their images and even sketches and find similar particles in its database. The novel system also works the other way around by informing users how to produce substances with the desired properties. Read on to learn how AI helps accomplish the challenges of materials science and what the scientists want to achieve with their research.

• ITMO Scientists Develop Method to Easily Synthesize Materials With Set Properties

  Researchers from ITMO’s SCAMT Institute have demonstrated the possibility of using the sol-gel method to produce various porous monolithic structures from magnetite nanoparticles. The new method can produce multifunctional materials with complex hierarchical structures, such as the xero-, cryo-, and aerogel of magnetite. Thanks to this approach, it is possible to control the composition of the resulting porous materials through the relation of their compounds’ concentrations. One of the method’s most promising applications is biomedicine – the new aerogel can be used to stop bleeding and xerogel can serve as a repository for drug transportation.

• Researchers Design New Synthesis Method for Carbon Nanodots With Potential Applications in Biomedicine

  Scientists from ITMO University, St. Petersburg State University, TU Dresden, Ioffe Institute, and City University of Hong Kong have devised water-soluble carbon nanodots that demonstrate efficient luminescence in the long wavelength spectral region. The researchers also managed to achieve the highest possible photoluminescence quantum yield reported so far for carbon nanodots emitting in the near-infrared spectral region. The developed nanoparticles can be used as non-toxic fluorescent probes for bioimaging. Read on to learn more about the study and its findings.

• ITMO Researchers Discover New Properties of Metasurfaces Thanks to Ultrashort Pulse Lasers

  A group of researchers from ITMO University, the Australian National University, and the Friedrich Schiller University Jena (Germany) has for the first time demonstrated effective generation of higher harmonics in silicon metasurfaces. This result was achieved due to resonant states with long lifetimes. The new discovery brings closer the creation of attosecond radiation sources based on semiconductor nanostructures. Ultrashort pulse lasers which earned their pioneers the Nobel Prize in Physics in 2018 make it possible to excite and explore very rapid processes in nature and matter. This opens new horizons for understanding ultrafast physics and faster information recording.

• ITMO Physicists Prove Feasibility of Non-Radiating States in Compact Acoustic Resonators: New Discovery Will Benefit Development of Acoustic Antennas and Sensors

  Researchers from ITMO University’s Faculty of Physics have succeeded in disproving a non-existence theorem which states that oscillations in open resonance systems must fade out by radiating energy into the surrounding medium. The physicists were able to calculate the shapes of acoustic resonators for which this theorem would not apply. In the resulting system, the energy of oscillations does not radiate into the surrounding space and remains within the resonator. Results of this research will facilitate the development of acoustic antennas and sensors.
