The COST Action contributed jointly with the EUREKA ENIWEP (European Network for Industrial Wear Prevention) Umbrella also dealing with friction control and industrial wear prevention.
200 participants from 35 countries attended the conference where 109 scientific papers were presented. 41 of those papers will appear in special issues of the highly ranked refereed tribology journals “Wear, Tribology International” and “Tribotest”.
COST Action 532 focused European research work on solving friction, wear and lubrication related problems in engines and transmissions. Researchers from 58 institutes from 30 countries used a total of 260 research man years to find new solutions to future industrial challenges.
A scientific breakthrough was the clarification of the basic mechanisms related to carbon-based low friction coatings. The one micrometer thick vacuum deposited diamond-like carbon surfaces can, in dry conditions, reduce the friction with up to two orders of magnitude. Now their interaction with lubricants and additives has been explained and new coating-additive chemical compositions developed.
Much work was focused on improving the understanding of environmentally adaptable fluids in engines and transmissions. New techniques for emission reduction in engines through the use of biogas, advanced lubricants, coatings and light weight materials were developed. A detailed theoretical and experimental study on a new piston-ring design whereby the hydrodynamic microlubrication was generated by a textured topography containing microdimples resulted in a 4 % fuel consumption reduction in engine tests.
Transmission systems were redesigned to improve the frictional conditions resulting in a power loss reduction of up to 74 %. The results are of benefit to the new industrial products and improvements in production methods in the 103 companies directly involved in the research work. The 42 projects carried out have already, at the end of the 5-year Action, resulted in 32 industrial improvements in commercial use.
The Chair of the Domain Committee Materials, Physical and Nanosciences, Axel Kranzmann and Science Officer Piotr Swiatek took part in that final event.

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
