Magnesium oxide nanocubes are compressed along the [001] direction in situ in the transmission electron microscope. Incipient plasticity in the smaller samples is characterized by the nucleation of few $ \raise.5ex\hbox{$\scriptstyle 1$}\kern-.1em/\k

Abstract The extremely elevated strength of nanoceramics under compression arises from the necessity to nucleate highly energetic dislocations from the surface, in samples that are too small to contain pre-existing defects. Here, we investigate the s

International audience; The mechanical behaviour of UO$_2$ single crystal is under debate due to the unexpected multi-slip observations in the experiments that involve dislocations in $\frac{1}{2}$ {100} slip systems but also in $\frac{1}{2}$ {110} a

International audience; While surfaces are known to have a limited impact on the mechanical properties of crystalline materials at the macroscopic scale, they play a key role at small-scale behaving alternatively as sources or sinks of various plasti
