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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
