Autor: Martine Mayne-L’Hermite, C. Reynaud, Mathieu Delmas, Dominique Porterat, Mathieu Pinault

Publikováno v: ECS Transactions. 25:757-762

Dense, aligned and clean multi-walled carbon nanotubes (MWCNT) can be obtained by aerosol-assisted catalytic CVD process. A successful extension of this method has been performed in order to obtain MWCNT growth even on carbon fibres and metallic surf

Langmuir, 2015, 31 (36), pp.9790-9798. ⟨10.1021/acs.langmuir.5b02607⟩

We investigate the shape and mechanical properties of liquid interfaces down to nanometer scale by atomic force microscopy (AFM) and scanning electron microscopy (SEM) combined with in situ micromanipulation techniques. In both cases, the interface i

MOCVD processed platinum–aluminum coatings on titanium alloys

Autor: Mathieu Delmas, Michel Pons, Magali Ucar, Constantin Vahlas, Laurence Ressier

Publikováno v: Surface and Coatings Technology. :49-54

Reduced oxidation and corrosion resistance at high temperature are limiting factors to the application of titanium alloys in aero gas turbine engines despite their interesting mechanical properties in view of their low density. Adapted protective coa

Physical Review Letters, American Physical Society, 2011, 106 (13), ⟨10.1103/PhysRevLett.106.136102⟩

Using atomic force microscopy with nonconventional carbon tips, the pinning of a liquid contact line on individual nanometric defects was studied. This mechanism is responsible for the occurrence of the contact angle hysteresis. The presence of weak
