Defects are no threat: scientists study unexpected properties of disordered nanolattices

Researchers of Siberian Federal University and their colleagues from Royal Institute of Technology (Stockholm, Sweden), Federal Bio-Medical Agency of Russia (Krasnoyarsk), Kirensky Institute of Physics of the SB RAS, Reshetnev Siberian State University of Science and Technology, and the University of Rochester (New York, USA) have studied the phenomenon of collective lattice resonance arising in the optical spectrum of ordered arrays of silicon nanoparticles.

SibFU scientists developed filter to suppress radio interference

Researchers from Siberian Federal University and Kirensky Institute of Physics proposed a new design for a multimode stripline resonator. The use of such resonators allows to create miniature band-pass filters with unique frequency-selective properties that are in demand by modern telecommunication systems. The main results of the study are published in the highly rated scientific journal Technical Physics Letters.

SibFU metallurgists developed non-stick coating without flaw

Scientists at the School of Non-Ferrous Metals and Materials Science of Siberian Federal University have developed technologies for producing aqueous and self-drying non-stick coatings based on natural and mechanically activated graphites used in the production of cast iron products. Results were published in the journal CIS Iron and Steel Review.

Siberian scientists develop an alternative to foreign-made diagnosis system for diabetes

Scientists from Siberian Federal University, Biophysics Institute of the Siberian Branch of the RAS and the Institute of Chemical Biology and Fundamental Medicine are developing a system for diagnosing diabetes mellitus by the content of hemoglobin in the blood combined with glucose. The development can replace foreign-made systems. The paper about the research is published in the journal Analytical Biochemistry.

New danger of dental implants discovered by Siberian scientists

Scientists of Siberian Federal University (SibFU) and Institute of Medical Problems of the North, while identifying the possible cause of a dangerous infection — peri-implantitis, suggested that it could be traces of foreign inorganic substances on the surface of new sterile dental implants. Intermediate results of the experiment are published in the journal "Dentistry".

URAP: SibFU has doubled its publication activity

On September 3, 2019, an updated version of the University Field Ranking by Academic Performance (URAP) was released. SibFU doubled its publication activity and rose by 29 positions in the subject ranking of URAP in physical sciences. The results have been published on the rating agency website.

Findings of 7000 year-long paleo-wood will help to predict the climate on the planet

Alberto Arzac, the head of the laboratory of biogeochemistry of ecosystems at the School of Ecology and Geography, Siberian Federal University, came back from an international expedition to the Yamal Peninsula, organized by his colleagues from the Institute of Plant and Animal Ecology, the Ural Branch of the Russian Academy of Sciences. In total, scientists brought along saw cuts of 500 trees over 7000 years old. The analysis of the annual rings of these saw cuts will help reconstruct the temperature changes of the past millennia and predict future climate changes.

Heatstroke for cancer cells: Scientists Test Nanoparticles to Target the Disease

SibFU Researches within an international research team investigated two types of core-shell nanoparticles with different core materials and gold shell to determine more efficient thermosensitizers for laser antitumor therapy. The researchers report that, according to their opinion, aluminum doped zinc oxide nanoparticles are the most effective. Key findings are published in the Journal of Quantitative Spectroscopy and Radiative Transfer.
