Quantum Bridge: scientists predict new plasmons

A research group of SibFU and Federal Research Centre “Krasnoyarsk Research Centre” of the SB RAS has predicted the existence of a new type of plasmons associated with charge transfer. According to the experts, the obtained result is very bright and promising in terms of creating the basis for producing ultra-sensitive biosensors of the new generation. Their work has been published in Journal of Chemical Physics, a highly-rated international journal.

SibFU Researchers come up with X-ray scissors to cut molecules selectively

A research team from Siberian Federal University and Institute of Physics (Federal Research Center, Krasnoyarsk Scientific Center SB RAS predicted a new physical phenomenon — recoil-induced molecular dissociation in hard-x-ray photoionization. The recoil effect is caused by electronic and photon intermolecular momentum transfer. In particular, the researchers forecasted that recoil experienced by a hydrogen molecule during the absorption of an X-ray photon and the emission of a photoelectron leads to a break in the chemical bond of the hydrogen molecule at photon energies greater than 5 keV. The research article is published in the peer-reviewed journal Physical Review A.

Temporary operation rules of SibFU

Siberian Federal University switches all the educational activities for our both degree and non-degree students and lecturers to online environment from 17 March 2020 till 4 April 2020. This is caused by preventive measures against coronavirus infection (COVID-19) and is based on the recommendations of the Ministry for Higher Education and Science of the Russian Federation and the ordinance on the organization of distance learning by acting rector Maksim Rumiantsev.

Born summiteer: scientists about the amazing abilities of Siberian stone pine

Scientists of Siberian Federal University for the first time have studied coniferous forests growing on the upper forest line in the West Sayan Ridge, mainly consisting of Siberian pine (Pinus sibirica Du Tour) and Siberian fir (Abies sibirica L.). It turned out that Siberian pine, or, as it is often called by locals, Siberian cedar adapts better to high altitude — the species has learned to develop comprehensive protection against hazards awaiting at the height (excessive insolation, abrupt temperature fluctuations).

To replace the "sandwich": scientists develop a super-miniature optical filter

A research team, which included scientists from Siberian Federal University and Krasnoyarsk Research Centre SB RAS, as well as scientists from Sweden and the USA, has proposed ultra-miniature devices allowing to isolate the ultra-narrow spectral line in the visible and infrared ranges of the spectrum from the broadband optical radiation and to control its location.

Digital immunity: SibFU scientists to teach AI to catch data leakage

SibFU scientists are developing a self-learning artificial intelligence system capable of detecting hidden information inbuilt in various media content disseminated in Internet resources. This artificial immune system mimics some of the natural processes that take place in the human immune system, for instance, it produces special digital antibodies to detect hostile antigens — media files which covertly embed additional information. The main results of the study are given in the article here.

The Fir Tree Remembers Warmth

International research team including a researcher from Siberian Federal University has found out that spruces sprouted in the south from seeds of northern populations and then planted in northern regions within reforestation event, “recalls” warmth and reveal specific features of its southern childhood, i.e. they bloom early and hibernate later. The researchers have suggested that this pattern is caused by stable epigenetic modifications acquired during some period of life that regulate these processes. The study was published in the Christmas issue of Scientific Reports journal.
