• Scientists Explain Why Paradise State Is Hard to Reach

  Authors of a paper on social relations’ modelling have adapted the popular model of human interaction in a society by adding individual preferences. According to the initial theory, human relations may reach a “paradise state” at some point. However, the new model contradicts this idea.

• ITMO Researchers Create Unique Wound-Healing Nanofibers Based on Hyaluronic Acid

  Researchers from the International Scientific and Research Institute of Bioengineering are the first to obtain nanofiber based on hyaluronic acid with introduced curcumin and usnic acid, natural biologically active substances. Such nanofibers can be used to create wound dressings for treatment of melanomas, burns, and ulcers.

• Researchers Develop Supersensitive Method to Measure Surface Topography With THz Radiation

  The method allows scientists to get an image close to a holographic one in its properties but with less energy input. In theory, the method could be applied in industrial quality control or acquiring images of concealed objects, for instance, in transillumination of envelopes.

• Scientists Develop Method to Facilitate Plant Growth with Glass-Ceramics Lamps

  Many may have seen bright pink light in some windows – it comes from special lamps that are used for providing sufficient lighting to house plants. Similar lamps are also used by farmers in greenhouses. Still, specialists in photophysiology argue that such lamps do not provide all the light that plants need. Scientists from ITMO in collaboration with their colleagues from Tomsk Polytechnic University came up with an idea to create light sources from ceramics with the addition of chrome: the light from such lamps offers not just red but also infrared (IR) light, which is expected to have a positive effect on plants’ growth. The research was completed as part of a Russian Science Foundation grant, and the results were published in Optical Materials.

• Scientists Grow Optical Chips in a Petri Dish

  The modern photonics industry is constantly working on making its devices more compact, be it computing systems or sensors and lidars. For this, it is necessary to make lasers, transistors and other elements smaller. A team of scientists led by ITMO researchers proposed a quick and affordable method to create optical chips right in a Petri dish. The research was published in ACS Nano.
