Fullerenes: optimising surfaces for anti-wear applications

25.01.2005


The problem of the tribological behaviour of materials had focussed on either improving friction or prioritising less wear and tear. The target of FOREMOST project (“FOREMOST: fullerene-based opportunities for robust engineering: making optimised surfaces for tribology”) is to achieve both effects simultaneously and, tot his end, the project will be based on the use of inorganic fullerenes (molybdenum bisulphate and bisulphate of wolframite). These new alotropic states of these well-known solid lubricants have the property of forming spheres of a few nanometers in diameter and forming layers like onion skins which act as “nano ball bearings” between the surfaces in contact.



The inorganic fullerenes are to be incorporated into three product families:

  • Hard layers: in which fullerenes display greater thermal stability than the bisulphates in their conventional state.
  • Polymeric layers and paints: products in which it is thought that the addition of fullerenes will increase “wetability” and, thereby, enable the rapid evacuation of the surface-deposited water (this is of particular interest in aeronautics as the rapid removal of water minimises the negative effects of ice on the moving control structures).
  • Lubricants (oils and fats): with the aim of reducing the coefficient of friction (there are already references in the literature that they are highly efficient in this function) and increase load resistance capacity.

The consortium is made up of Ion Bond, Microcoat, Fuchs Petrolub, Spolchemie, Nanomaterials, Renault, EADS, Rolls-Royce and Goodrich, amongst others. Also participating is the Institute of Materials Sciences of the National Council for Scientific Research and Fatronik Technological Centre. The project will be co-ordinated by the TEKNIKER Technological Centre.

According to the dates established, this large-scale integrated project will start its activities in March 2004 and conclude in September 2008.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
