To help the nature to recover from harmful impacts of the mining industry, Svetlana Mesyats and her team from the Geological Institute of the Kola Research Center RAS offer the method, which implies the application of a thin invisible polymeric film onto the soil surface and provides for a fast and successful minesite recultivation.Polymer Protects Grass
It is not surprising that such a polymeric covering is invented in Apatity. People leaving on the Cola Peninsula often need to deal with a destroyed soil cover and a bare infertile land. As a consequence of mining, a significant part of the peninsula is either stripped of the upper ground layer or buried under dumps of the barren rock. Water and wind erosion and sharp fluctuations in temperature make it impossible for a young grass to survive on this infertile ground, only clouds of dust fly over these bare lands. And such a situation is just the same in all mining and metallurgical areas in the North.
However, in the environs of Apatity the problem of dust storms has been solved. A thick grass cover has been created on barren rock dumps, and eyes and mouths of local population are no longer filled with the tons of dust. The idea is as simple as any stroke of genius.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
