Netherland: PhD position in Proton transfer in nanoconfined water at FOM Institute AMOLF

Font size: Decrease font Enlarge font

Job description

Aqueous proton (H+ ion) transfer is an extremely important and widespread process in nature that shows exciting physical properties. For bulk liquid water evidence has been found that proton transfer involves a special conduction mechanism in which the proton charge is transferred between hydrogen atoms located on different water molecules. This transfer strongly relies on the structure and dynamics of a large number of nearby water molecules. Aqueous proton transfer often takes place in nanometer sized volumes of water, like for instance in trans-membrane channels, and in the channels of nafion membranes in hydrogen fuel cells. The nano-structuring of water in these channels will probably affect (enhance?) the rate of proton transfer.
In this project we will study the mechanism of proton transfer through different types of nano-channels, in particular in so-called metal–organic frameworks that are promising proton conducting materials for applications in fuel cells. This research will be performed with ultrafast spectroscopic techniques like two-dimensional infrared spectroscopy and time-resolved surface sum-frequency generation spectroscopy.

Organisation

FOM Institute AMOLF

FOM Institute AMOLF performs leading fundamental research on physics of Biomolecular Systems and Nano Photonics; two areas with key potential for technological innovations. The Institute contributes to knowledge transfer to industry and society and trains talented young researchers. AMOLF is located at Science Park Amsterdam, The Netherlands, and engages approximately 140 scientists and 70 support staff. See alsowww.amolf.nl

The goal of the Ultrafast Spectroscopy group is to study the molecular-scale properties of water, ice and aqueous systems like hydrated ions, membranes and proteins. The research is carried out using spectroscopic techniques including femtosecond (nonlinear) vibrational spectroscopy, surface sum-frequency generation and GHz-THz dielectric relaxation spectroscopy.
