Molecular approach for the synthesis of supported nanoparticles on active carbon using noble metal clusters

Bertrand P., Delcorte A., Devillers M., Dubois V., Hermans S., Vidick D., Willocq C., Université catholique de Louvain, BE

A molecular approach was envisaged for the preparation of nanoparticles supported on carbon. The support was first treated in order to build suitable anchors for organometallic compounds on the surface. Palladium clusters of various nuclearities [...]

Size Effect on the Elastic Modulus of Nanomaterials as Measured by Resonant Contact Atomic Force Microscopy

Cuenot S., Demoustier-Champagne S., Frétigny C., Nysten B., Université catholique de Louvain, BE

The elastic modulus of metallic nanowires and polymer nanotubes was measured using a novel method called resonant contact atomic force microscopy. The direct application of a normal load to the contact was obtained using a [...]

Binary Chemical Nanopatterns: Fabrication and Use as Templates for Electrostatic Self-Assembly

Baralia G., Jonas A.M., Moussa A., Nicol E., Nysten B., Pallandre A., Université catholique de Louvain, BE

We report on surface-directed macromolecular self-assembly at the nanoscale, starting from 2D templates produced by combining electron beam nanolithography with surface chemistry. As assembly process, we concentrate on electrostatic self-assembly, which allows to grow functional [...]

A Fluoro-ethoxysilane-Based Stiction-Free Release Process for Submicron Gap MEMS

Jonas A.M., Pallandre A., Parvais B., Raskin J-P, Université catholique de Louvain, BE

Nowadays, stiction remains one of the biggest reliability problems in the fabrication of micro-electromechanical systems (MEMS), especially when a small gap is used. To avoid the adhesion, a Self-Assembled Monolayer (SAM) can be coated. Main [...]
