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.

ITMO University Specialists Find Out How Much St. Petersburg Citizens Trust Online Shops, Communication on Social Media, and Online Banking
Specialists from the eGovernment Center of ITMO University’s Institute of Design & Urban Studies have conducted a research on the degree to which St. Petersburg residents trust modern technologies, both generally and in specific spheres of life. In particular, the sociologists tried to determine how much the citizens trust online shopping, communicating with government agencies on the internet, and data security on social networks. The work is conducted within the framework of the Russian Foundation for Basic Research project No. 18-311-20001 “The study of cyber-social trust in the context of the use and renouncement of information technologies”. ITMO.NEWS contacted the project’s head Lyudmila Vidyasova to find out what conclusions the researchers came to.

Scientists Report on Crucial Reduction of Indian Lion Genome Diversity
Modern bioinformatics allows us to take a look into the past and find out when certain species diverged during evolution, which of them still are genetically close to each other, and which are not. An international team of researchers, which, among others, includes the academic supervisor of ITMO University’s Laboratory of Genomic Diversity and researchers from the University of Copenhagen, Barcelona Institute of Science and Technology, and other research centers from all over the world, analyzed the genomes of extinct and living lions. They managed to determine when the divergence took place, as well as come to several other conclusions on genetic diversity of the modern lion population in India. The results are published in the journal Proceedings of the National Academy of Sciences of the United States of America.

ITMO University’s NTI FoodNet Curator Olga Orlova: the Pandemic Will Make Food Safety a Long-Term Trend
Early 2020 was a highly unclear time for the food tech industry. On the one hand, the coronavirus pandemic has led to a mass closing of restaurants and reduced demand for the products of food production facilities; on the other hand, it brought about a boom in the food and grocery delivery market. It is already clear that even when the period of self-isolation is over, the industry will take a while to come back to the way it was in late 2019. We spoke to Olga Orlova, the head of Infochemistry Scientific Center’s food tech digitization team and ITMO University’s representative as the curator of National Technological Initiative’s FoodNet program, about what awaits the industry in the near future and what kind of specialists it will require.

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.

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.

ITMO University’s Congress of Young Scientists Held Online for the First Time
The novel coronavirus pandemic has forced theaters, museums and concert halls to move into the digital space – and scientific events are not an exception. This year, the Congress of Young Scientists was set, for the 17th time, to bring together talented researchers at ITMO University. But 2020 turned out to be historic, and this Congress – unique. As part of the reviewed arrangement, young scientists will be presenting their research and communicating with experts on Zoom.

Study Abroad at Home: ITMO University Student’s Experience
Evgenia Ponomareva, a student at the Faculty of Photonics and Optical Information, and an employee at the Laboratory of Femtosecond Optics and Femtotechnologies, was supposed to study abroad, at Aalto University (Finland) from January to May. However, due to the pandemic, she had to return to St. Petersburg in March. She continues her studies at Aalto University remotely. Evgenia tells us how she studies in Finland from Russia and continues her research from home.
