The echelle atomique libre (EAL) is the basis of international atomic time (TAI). It is a weighted average of several hundred atomic clocks of different laboratories spread worldwide. The weights of the original weighting algorithm of the weighted av

The study of nano-objects is of particular interest due to their outstanding mechanicalproperties. While metal nanocrystals are generally characterized by high yield strength and ductility under extreme compressive stress, very few is known about oth

International audience; Recently, W-based catalysts have provided a promising route to synthesize single-walled carbon nanotubes (SWCNTs) with specific chirality, but the mechanism of the growth selectivity is vaguely understood. We propose a strateg

In order to control energy losses in mechanical systems, a thin film of lubricant is often introduced between the solids in contact. The lubricated point contacts operate in the elastohydrodynamic regime, characterized by high pressures (of the order

Selon la théorie de Cottrell et Bilby, les dislocations à travers leur champ de contrainte interagissent avec les atomes de soluté qui s’agrègent au cœur et autour des dislocations (atmosphère de Cottrell). Ces atmosphères « bloquent » les

The objective of the thesis was to understand the microscopic features at the origin of ageing in metals. The originality of this contribution was the com- bination of three complementary computational techniques : (1) Metropolis Monte Carlo (MMC), (
