The Moscow radiochemists have developed and applied in practice new methods for analysis of transuranium elements in the environment objects. With the help of the most up-to-date techniques, they have investigated in detail the americium and plutonium migration paths in water and soils of some regions in Siberia and Southern Ural which are in particular need for such type of monitoring – in the vicinity of the Federal State Unitary Enterprise “Mayak” Manufacturing Company and Federal State Unitary Enterprise “GHK” (“Mining and Chemical Enterprise”) - i.e. the areas where nuclear fuel is produced and nuclear waste is utilized.
This investigation seems too specific at first sight, but in fact it refers to every inhabitant of the planet. As in the post-nuclear epoch, after all types of experimental and not only experimental explosions, radio-active waste discharge into open water bodies, technological failures and accidents at the nuclear fuel cycle enterprises, there is not a single location on the Earth which is absolutely free of transuranium elements. Apparently, there would be no such locations in the future. Therefore, Russian researchers are now actively developing new analytical methods to ensure safety of people.
The problem is that the concentration of these radionuclids in the objects of the environment are extremely low, therefore, the researchers have to literally seek individual atoms. Before chemical analysis is carried out, these elements need to be educed from water and soil and concentrated. Respective analytical methods were developed in the Radio-Chemistry Laboratory, Vernadsky Institute of Geochemistry and Analytical Chemistry, Russian Academy of Sciences. Doctoral thesis by Alexander Novikov, who has recently withheld it successfully, is devoted to this topic.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
