Titre : From Passivating Monolayers to Romantic Surfaces: Surface Chemistry for Better Interface Control.
Endroit : Pavillon J.-A.-Bombardier, salle 1035 à 9 h
Hôte : Professeure Françoise Winnik
La conférence sera prononcée par le professeur Han Zuilhof, du laboratoire de chimie organique de la Wageningen University (Pays-Bas).
Résumé : Over the last decade the modification of surfaces by the stable and directed attachment of a monolayer of organic molecules has allowed a range of novel physical and biological phenomena. The presentation outlines the basic chemistry behind this, and applications from ultra-low friction surfaces to anti-fouling coatings. Along the way I will show the power of mass spectrometry in the surface analysis of such thin layers. Finally, I’ll wrap up with a molecular love story.
