Localized light will help improve medical sensors

Scientists of Siberian Federal University, as part of an international scientific team, investigated a special state of light that occurs at the interface between a cholesteric liquid crystal and a layered medium. The researchers created a digital model of this phenomenon and showed how to change the lifetime of a bundle of light and its wavelength. It is assumed that in the future it will help to create effective sensors for conducting medical tests — including at home. An article with the primary results of the work was published in Crystals.

Russian scientists create a three-layer sorbent to purify drinking water from zinc

Scientists of Siberian Federal University have developed an inexpensive highly selective sorbent with a “three-layer” structure. It reacts exclusively to zinc contained in samples of drinking water from artesian wells and natural reservoirs. The experts assure that a very small amount of their sorbent is sufficient to determine the presence of a hazardous metal in water, and its concentration can easily be evaluated by the glow of the sorbing agent: the brighter the glow the more zinc, and the more dangerous this water is for living organisms.

SibFU Student wins two golds at FIS Alpine European Cup

Aleksey Bugaev, a student of the School of Physical Education, Sports and Tourism, Siberian Federal University, won two gold medals at the 1st stage of FIS Alpine European Cup among athletes with a lesion in the musculoskeletal system and visual impairments. Competitions were held on 7–8 November 2019 in Landgraaf (Netherlands).

SibFU researchers participate in creation of "perfect green" for smartphone and TV screens

A research team from Siberian Federal University, Beijing University of Science, and Technology and South China University of Technology obtained a rare-earth silicate phosphor with exceptional properties — it emits an almost monochrome green color, which could be called "perfect green". This material is assumed to improve the color reproduction of the screens of all modern gadgets, especially televisions. Also, the finding will help improve the new generation of LED lamps.

Researchers will „pimp out“ the organic dye fluorescein for the needs of toxicology and medicine

Researchers of Siberian Federal University and their colleagues from L.V. Kirensky Institute of Physics of the Siberian Branch of the Russian Academy of Sciences (SB RAS) revealed structural and behaviour features of fluorescein, an organic compound used in medicine and the environmental industry as a highly sensitive probe. The results of their study have been published in Dyes and Pigments.
