Optical Computers Explained: Will They Replace the Regular Kind?
Modern computers are becoming increasingly more power-hungry and their performance doesn’t always meet our needs. Some say that optical computers could be the solution. ITMO University professor Ivan Iorsh spoke to ITMO.NEWS to help us learn what they are.

ITMO Researchers Discover Material With Refractive Index Higher Than in Silicon
This will potentially allow them to create more compact and efficient elements for lasers, sensors, and optical chips. Moreover, it proves the hypothesis that ITMO physicists had about the connection between a material’s refractive index and its electronic features. The research has been published in Nanophotonics.

ITMO Researchers Win Grant for Development of Smart Glasses Components
The scientists will develop a method for the development of waveguides invisible to the naked eye and which will make it possible to transmit images onto transparent glass and polymer surfaces. It will also be possible to use the same technology to create sensors useful in the production of protective eyewear for workers in hazardous occupations.

Picture of the Week: Perovskite Inorganic Quantum Dots
The effect that can be seen on the picture is called photoluminescence. Quantum dots made out of cesium perovskite receive ultraviolet light that gets absorbed by quantum dots and then re-emitted, but in the spectral range.

Scientists Use Lasers and Gold Particles to Turn Titanium Oxide Into Nanocomposite for Photocatalysts
Oxides of different metals often serve as photocatalysts in various systems such as air purification, reactions of water decomposition and even in the production of self-cleaning surfaces for glass and mirrors. The physical-chemical properties of such materials can be improved by adding nanoparticles, which turn an ordinary oxide into a nanomaterial with new capabilities. To successfully perform this, however, it is necessary to understand the processes going on as a nanocomposite is being formed, and to be able to control them. ITMO University researchers together with their colleagues from France and the USA have demonstrated how a femtosecond laser can be used to tune the structure and nanocomposite properties for titanium dioxide films filled with gold nanoparticles. The paper was published in ACS The Journal of Physical Chemistry C.
