September 2011 - MaNEP and the University of Geneva are celebrating 100 years of superconductivity. 
July 2011 – A one dimensional electronic state has been uncovered along the core of a self assembled endotaxial Si nanoline at the Si(001):H surface, with a range of promising properties to explore 1D physics. 
May 2011 – The anisotropic surface stress induced by Bi-nanolines is found to block the formation of embedded structures and stabilizes the nucleation of manganese silicide islands which grow in a preferred direction, forming nanowires on Si(001). 
March 2011 – The oxygen migration scenario for electroresistive switching in manganites gets new support. Mobile oxygen adatoms and defects have been observed by scanning tunneling microscopy with atomic resolution at the surface of PrSr2Mn2O7. Collaboration with the
