Postdoc:Proton conduction at aqueous interfaces studied with nonlinear femtosecond spectroscopy
In this project you will use advanced femtosecond spectroscopy techniques to study the properties of water and hydrated protons near hydrophylic and hydrophobic surfaces. You will use the highly surface-specific technique of vibrational surface sum-frequency generation (VSFG) to study the hydrogen-bond configuration of water molecules and hydrated protons near metal-oxide surfaces, hydrophobically coated metals, and graphene. With VSFG you will also investigate how the water molecules and hydrated protons interact with the molecular groups of these surfaces. You will also study the molecular dynamics near the surface with the technique of time-resolved VSFG, in particular you will study the rate at which hydrogen bonds are broken and reformed, and the rate and mechanism by which protons are conducted along the surface. The studies will yield new fundamental physics knowledge and insights, which will be highly relevant to the better understanding and control of (photo)catalysic processes.
About the group
We study the molecular-scale properties of aqueous solutions and aqueous interfaces. This research is carried out using spectroscopic techniques including femtosecond vibrational spectroscopy, vibrational surface sum-frequency generation and GHz-THz dielectric relaxation spectroscopy.
You need to meet the requirements for a doctors-degree and must have research experience in a non-Dutch academic environment. You have successfully completed doctoral studies in experimental physical chemistry or experimental physics. You are expected to have experience in femtosecond laser spectroscopy of molecular and/or condensed phase systems. Experience with the technique of surface sum-frequency generation is a bonus.
Terms of employment
The position is intended as full-time (40 hours / week, 12 months / year) appointment in the service of the Netherlands Foundation of Scientific Research Institutes (NWO-I) for the duration of two years with the possibility of extension with another year. AMOLF assists any new foreign postdoc with housing and visa applications and compensates their transport costs and furnishing expenses.
