  • 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 Scientists Suggest Cheap Way to Control Optical Signals With Halide Perovskites

    Halide perovskites are a relatively new group of materials that are used in solar cells, diodes, scintillators, and other devices. One of their main advantages is their availability and ease of production. They are also characterized by the stable bound state of an electron and an electron hole that makes up an exciton. By connecting an exciton to light in a photonic crystal plate, the researchers were able to reach record optical nonlinearity values, which makes the plates a promising tool for controlling optical signals and, in the future, can render them useful in optical computers. The article describing the experiment was published in Nano Letters.


  • 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.
