Researchers of the Bochvara All-Russian Scientific Research Institute for Inorganic Materials, supported by the International Scientific and Technical Center have developed new tilth technology, which allows to get rid of radioactive or poisonous dust, to transform dust-forming slag-heaps into green lawn and even to grow forest in the desert.
The technology is based on the polyelectrolytes developed by chemists of the Lomonosov Moscow State University. The polyelectrolytes are polymers, the chains of which carry different charges. “When the polymers contact, they combine strongly with each other, explains Academician Kabanov, one of the authors of the development. This is their first advantage, and the second one is that they are capable of joining to any specks of dust, as the specks’ surface always carries electric charge. If the soil is tilled by polyelectrolytes, they will form a solid crust”. The crust will contain nubbins of soil, grains of sand, and various small and fine specks of dust get combined together by adhesive polymeric filaments resembling the spiders web. Such crust lets the air through excellently and it is even capable of accumulating moisture, that is why the seeds contained in the crust get into microhotbed conditions and germinate well.
The major challenge in developing the technology is that polyelectrolytes, when located in the same solution, react immediately and precipitate. That is why the soil is to be initially tilled by the solution of the first polymer and then by the solution of the second one. “This technology cannot be applied when large areas are tilled from helicopters, says Sergei Mikheikin, leader of the effort. The task was set up as follows: create one-pass tillage technology. We have succeeded in finding the way out – some salt was added to the solution”.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
