Oil and oil products spill often and in various places. These are plots in oil production areas and pipeline breaking locations and places of tanker wracks or crashes of consists, which carry oil products. At best, oil spillage falls on hard soil: it can be collected and somehow refined or, at the worst, buried. The case is much worse if the spillage takes place on water.
The oil film spreads out quickly to large distances, and it is very uneasy to collect. A thick film is removed by sea bulldozers by “scraping it off” water surface. As for a thin film, which produces iridescent spots, it is practically impossible to eliminate. By the way, its emergence does not require any disastrous events at all: a film may drift behind an ordinary motor-launch if its engine does not run well. A film several microns thick may seem to produce little impact. For water inhabitants, it emergence can mean certain death: it reduces oxygen dissolving in water drastically.
Therefore, the problem of fighting oil film is more than urgent. There is only one remedy for it: sorbent that is capable of taking in oil products. It is also desirable that the sorbent itself did not contaminate the environment and was able to turn carbohydrates into something quite harmless. Researchers of three institutes – Snezhinsk All-Russian Scientific Research Institite of Technical Physics (VNIITF), Novosibirsk State Research Center “Vector” and the Syktyvkar Institute of Biology (Komi Research Center, Ural Branch, Russian Academy of Sciences) with financial support from the International Science and Technology Center (ISTC) – managed to combine all three components of an ideal sorbent. Significant assistance was also provided by the US colleagues. Furthermore, the partner of the project – the Kirov Center for Ecological Initiatives “Press-Torf (Peat)” – even arranged production of sorbent trial lots.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
