The electronic properties of these materials are sensitive to their environment... The Nobel Prize for Physics has recently been awarded to Andre Geim and Konstantin Novoselov, of the University of Manchester in Great Britain for" their revolutionary experiments on a two-dimensional material, graphene
Ceramics have been a little neglected recently but they still have something to reveal to us: the latest generations of eutectic" ceramics are very promising for engines, while ceramic composites- more traditional- have had a new lease of life with the development of low-cost processes... But then we come up against the limits of the materials used to manufacture the engine
Joint work by Onera and the Kastler Brossel laboratory is leading to progress in knowledge of" twin" photons, with the promiseof new quantum applications. When a beam of light passes through certain materials (referred to as non- linear), the photons of the beam spontaneously split into two photons, referred to as" twins"
Carbon nanotubes, long extremely thin tubes discovered twenty years ago, are very promising for the elaboration of new sensors highly sensitive to pollutants and explosives... Image of the electronic wavefunction of a nanotube obtained by tunnel effect microscopy 1. ONERA hasn't missed the boat when it comes to nanotechnology: since 1998, it has taken a close interest in nanoscience, which concerns objects of a few nanometres in size, that is, billionths of a meter
