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 Twist Particles Using Quantum Entanglement
Twisted particles have found their applications in many fields, such as optomechanics, biology, astrophysics, as well as quantum optics, information science, and communications, where, for instance, they can be used to increase data capacity. However, as these particles are primarily obtained through diffraction gratings, they can’t yet be used for experiments in nuclear and particle physics given the high energies of particles used in contemporary colliders. As a solution to this problem, physicists from ITMO University have suggested a method of obtaining such particles using the so-called generalized measurements, without relying on any special equipment. Their research was supported by a Russian Science Foundation grant, with its results published in The European Physical Journal C (Particles and Fields).

A Quiet Place: ITMO Physicists Reduce Noise Tenfold With Metamaterial Structure
Imagine you are in a park in the bustling downtown and there is sunshine, fresh air, and… total quiet. Doesn’t feel real, does it? Researchers from ITMO University have developed a translucent vented structure that decreases noise by up to 20 dB within the spectral range of 2 to 16.5 kHz. This means that it covers 70% of the audible bandwidth. The new structure can be used to build noise-insulating barriers alongside roads or pavilions in parks.

ITMO Researchers Developing New Cancer Treatment Using Gold Nanoparticles and Infrared Lasers
In recent years, oncological diseases have become one of the most wide-spread causes of death in developed countries – and despite the abundant new diagnostics and treatment methods, fighting cancer is still a challenge. Nearly all known treatments have significant side effects, while some of them are even helpless against more persistent cancer cells. One solution to this problem is photothermal therapy, on its own or in combination with other treatments. Researchers from ITMO University have suggested a new method to treat melanoma more effectively and safely using gold nanoparticles. Read on to learn more about the new method.

ITMO Scientists Create Method to Quickly Detect Painting Authenticity
In collaboration with the staff of the State Russian Museum, researchers from ITMO University have developed a new method for detecting painting authenticity with infrared spectroscopy. The method will allow the museum’s experts to quickly identify a painting’s chemical compounds and the century it was created in, as was demonstrated by a test analysis performed on a copy of one of Ivan Aivazovsky’s creations. In the future, the new method will help identify the authenticity of pieces from the era of Russian avant-garde.

ITMO and VK: Main Takeaways From Major Study of Gamedev Educational Programs
According to a recent study conducted by ITMO, VK Education, and VK Play, the number of all educational programs in gamedev increased by 45% in the last two years. Despite the growing interest in short online courses, full-scale university programs in the field have also been increasingly popular, with their number increasing by 25%. Read on to learn about other educational trends in gamedev.

ITMO Researchers Create Virus-Detecting DNA Bot
A team of scientists from ITMO University have used DNA molecules to develop a high-performance nanobot that detects pathogens. Its effectiveness has been tested on COVID-19, but the technology may be adapted to seek out other viruses. Unlike PCR testing, this method does not require costly reagents, complex equipment, or trained personnel while demonstrating the same level of accuracy.

Student Spotlight: David Castro, Ecuador
Should I do a PhD? That’s the million-ruble question. We are no strangers to the fact that PhD studies can be super stressful. Yet so many students do it. How do they maintain their work-life balance? Do they get paid enough? Is it obligatory to publish several Scopus-indexed papers every year? Let’s find out from David, a South American who is currently a second-year PhD student at ITMO.

ITMO Scientists Create Ultra-Broadband Carbon Dots With Biomedical Applications
Carbon nanodots are a new trend in science, now used in smart packaging, warranty tags and with potential applications in diagnostics and tumor visualization. However, in order to be used in biomedicine, carbon nanodots have to be made visible through the human skin. This has recently been achieved by researchers from ITMO University, the Ioffe Physical-Technical Institute, and North Ossetian State University, who synthesized nanodots with unique properties: they can radiate and absorb light in the infrared spectrum. Such newly developed dots can be used for tissue visualization in medicine. Learn more about the new carbon dots synthesis method and its practical applications in this article.
