Firstly, graphene is of great theoretical interest for physicists... Graphène also has numerous properties which make it very promising... 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
This Ka-band, whose frequencies are at the boundary of the window of use of radar waves through the atmosphere, promises unmatched performance for altitude measurement and resolution, from a single satellite, by day or by night, regardless of the weather conditions... Great advances are expected; the applications range from current measurements on a global scale, to the measurement of the slow evolution of mountain glaciers
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... Most metal alloys are unable to resist temperatures greater than 1 100 ° C, and ceramics are fragile
Drones are not just for the exclusive use of the military and they can also be of great use for civil surveillance, for example in the battle against forest fires... "The complementarity between the optical imaging and the radar seems to be quite promising", enthuses Claude Le Tallec
