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.
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.
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.
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.
Scientists of Siberian Federal University have tested the compatibility of four biopolymers with human and animal blood cells. The authors of the study claim that these compounds have huge potential for application in medicine. For example, in the future, it is possible to significantly reduce the number of postoperative complications in cardiovascular surgery due to the use of biopolymers as a coating for vascular endoprostheses (stents). The results of the study have been published in the International Journal of Biological Macromolecules.
The R&D product by the researchers of Siberian Federal University will allow cutting desalination costs tenfold by reducing energy costs for heating and stopping the use of chemical additives in desalination.
