• Scientists Create Smallest Semiconductor Laser That Works in Visible Range at Room Temperature

  An international team of researchers announced the development of the world’s most compact semiconductor laser that works in the visible range at room temperature. According to the authors of the research, the laser is a nanoparticle of only 310 nanometers in size (which is 3,000 times less than a millimeter) that can produce green coherent light at room temperature. The research article was published in ACS Nano.

• ITMO Staff Visit University of Toronto as Part of Megagrant Research Project

  The ongoing pandemic has made the academic community to put a lid on all forms of direct scientific contact such as conferences, internships, and exchanges. Two researchers from ITMO University got lucky: they were able to do an internship at the University of Toronto (Canada) mere weeks before the country closed its borders. We got in touch with them to find out what impressed them most about their Canadian colleagues’ practices, how they had to outrun the travel lockdown, and how their research continues at home.

• A Quantum Walk Forward: Researchers Find Way to Discern Cases of Effective and Ineffective Quantum Computation

  Quantum computers are becoming increasingly common in the headlines of high tech publications. Giants like Google and IBM fight for supremacy in the field of quantum computing. Every once in a while, prototypes are exhibited at high tech fairs. But, as scientists point out, science still hasn’t solved the fundamental problems that would define the effectiveness of quantum computers. One such problem was tackled in a recent article by an international research team that includes staff members of ITMO University. The study was featured on the cover of Advanced Quantum Technologies.

• From Digital to Optical: Scientists Demonstrate the Work of First Chemically Synthesized Optical Switch

  Today, scientists from all over the world face the task of creating optical switches. These devices will allow for transmitting information in binary code with the help of light, which in the future will be useful for the development of ultrafast optical memory cells. ITMO University scientists have demonstrated how to create, using a femtosecond laser, an all‐optical switch based on a metal‐organic framework which can be synthesized in vitro and is usually used in chemistry for gas absorption. The research has been published in the journal Angewandte Chemie.

• 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.

• Suvorov Canals: Russia and Finland to Cooperate on Development of Important Historical Objects

  The project on the restoration and development of a complex of canals and fortresses located in the border territory between Finland and Russia unites seven organizations from both countries, including ITMO University. The Faculty of Software Engineering and Computer Systems’ Center of Usability and Mixed Reality contributes as a technological partner – its remit includes the development of different multimedia and an interactive map of the project.

• Optical “Nanomixer”: Scientists Propose New Method for Mixing Liquids

  Every now and then, scientists need to control the process of mixing liquids in vessels so small that the thinnest needle or even a hair won’t fit in there. At the same time, controlling the diffusion speed of molecules in the so-called microreactors is extremely important for the purposes of designing new drugs, conducting biological experiments and even diagnosing diseases fast enough. Scientists from ITMO University and their colleagues from the Czech Academy of Sciences proposed to solve this problem by using the energy of light. Their research has been published in Advanced Science.

• Scientists Develop Light-emitting Composite Material Based on Perovskite Nanocrystals with Air- and Water Resistant Optical Characteristics

  An international team of scientists including researchers from ITMO University has developed a new composite material based on perovskite nanocrystals to fabricate miniature light sources with improved performance. Protection of perovskite nanocrystals within porous glass microspheres made it possible to increase their stability by almost 3 times. Moreover, the subsequent coating of these particles with polymers resulted in the fabrication of water-dispersible luminescent microspheres based on CsPbBr3 nanocrystals. This method of fabrication is especially important for the implementation of perovskite nanocrystals in diverse biological applications. The results have been published in ChemNanoMat.

• Russian and Dutch Researchers on What’s Holding Back a Revolution in Data Storage

  Almost all of us store data on cloud services and use social networks. Some know that servers hosting that data occupy whole buildings and require significant resources to maintain. The world’s best researchers are at work trying to make data hosting more affordable, secure and user-friendly, but no revolutionizing changes have happened so far. Recently, Alexandra Kalashnikova, a physicist at the Ioffe Institute and ITMO University, along with colleagues from Radboud University Nijmegen (the Netherlands) and the Prokhorov General Physics Institute of the Russian Academy of Sciences have published a paper in Physics Reports. In the article, researchers explain why the industry hasn’t yet begun recording data on HDDs with lasers, or dropped disk drives altogether. Alexandra told ITMO.NEWS more about the paper.

• Scientists Propose a Carbon Dot-Based Method for Increasing the Efficiency of Solar Cells and LED

  An international group of scientists, including some from ITMO University, has proposed a method that allows for significantly increasing the efficiency of solar cells and light-emitting diodes. The scientists managed to achieve this result by augmenting the auxiliary layers of the devices responsible for electron transport rather than working with the main active layer. The work has been published in the journal Advanced Functional Materials.
