• ITMO Scientists Increase Sensitivity of Levitating Particle Sensors

  Researchers from ITMO University studied the movement of a single levitating microparticle and found the optimal state when it becomes highly sensitive to small external influences. This effect can lay the foundation for a general-purpose sensor that would precisely and quickly measure the vector of gravity, acceleration, angular moments, and directed weak force. Such data will be useful in geological exploration, as well as in detecting seismic activity or locating ships and other vehicles. The study was published in Physical Review A.

• Scientists Studied Hybrid Nanoparticles Capable of Generating Broadband Radiation

  An international group of scientists from Russia, Germany and France, including those from ITMO University, conducted a large research at the intersection of materials science and photonics. The research is dedicated to the study of a hybrid nanostructure, a plasmonic golden sponge (Au), the pores of which are filled with crystalline silicon (Si). The peculiarity of this material is that when excited by a laser beam, nanostructures generate broadband radiation which covers the visible range of the spectrum and partially the near-infrared range. The hybrid nanostructure can be used in broadband near-field microscopy. The results of the research and its application prospects have been published in the Nanoscale journal.
