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 Suggest Using Gold Nanoparticle Metasurfaces to Determine Substance Molecular Composition
This will make it possible to create compact devices that will accurately determine molecular composition of a liquid or gas, and help identify potentially dangerous chemical compounds. The results of the work carried out by researchers from ITMO University and Ben-Gurion University of the Negev, Israel have been published in Nanomaterials.
Svetlana Ulasevich is an associate professor and researcher at ITMO University’s Infochemistry Scientific Center, as well as a specialist in sonochemistry, electrochemistry, and biomimetic materials.
In the future, this breakthrough will help boost the accuracy of MRI scans and enlarge the MRI chamber in order to improve the patient experience. Results of this research may also be put to use in research-purpose high-field MRI systems.
Promising Materials, Reservoir Computing and Li-Fi: Research at ITMO’s International Research Center of Functional Materials and Devices of Optoelectronics
Since the time of its foundation, researchers of ITMO’s International Research Center of Functional Materials and Devices of Optoelectronics have succeeded in publishing over 600 research articles, getting over one and a half billion rubles in funding from the Ministry of Science and Higher Education of the Russian Federation, Russian Science Foundation, and Russian Foundation for Basic Research, and completing 36 major projects, international-level projects included. As part of an Open Day, researchers from the center’s six laboratories and its head Alexey Romanov spoke about its structure, international research activities, and project work.
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.
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.
