Séminaire 24.09.2015 – 11h00

Alenka Luzar (Virginia Commonwealth University), présentera un séminaire le 24 septembre à 11h dans la bibliothèque du laboratoire PHENIX (7e étage, bâtiment F, porte 754) intitulé :

Small is beautiful, and smart : Reversible control of nanoscale hydration


As accessible experimental length scales become shorter, the modification of interfacial properties of water due to nanopatterned surface topography, functionalization, or electric field, must come to grips with novel effects existing at the nanoscale. The talk will review our theoretical and molecular simulation works that predict and elucidate thermodynamic driving forces and kinetic factors pertinent to nanoconfined water and its saline solutions. Examples will range from changes in hydration and water-mediated interactions in response to surface texture, to nanoelectrowetting. A picture emerges in which molecular modeling can dissect nanoscale phenonema in ways that surprise. Applying this knowledge, we will show how to tailor wetting properties in a reversible manner, to make smart or responsive surfaces for dynamical tunable devices
