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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
