The Leiden Institute of Chemistry is part of the Faculty of Mathematics and Natural Sciences of Leiden University. Leiden University is a member of the League of European Research Universities.

The experimental section of the Soft Matter Chemistry group is headed by dr. Alexander Kros who received in 2009 the prestigious European Research Council (ERC) award. The current group is composed of 10 PhD-students, 3 postdocs and 2 technicians. Our group has an organic synthesis lab equipped with 2 peptide synthesizers and equipment for analysis (i.e. FT-IR, CD, optical and fluorescence spectroscopy, CLSM) Furthermore we have direct access to AFM, SEM, TEM, NMR, cell culture facilities. We collaborate with several research groups within Leiden University and other Universities.

We offer a position for a:

PHD STUDENT, on the subject Model Systems for Membrane Fusion (38 hours a week)
vacancy number: 10-178

In this project you will develop devices for the generation of molecular hydrogen and electrical energy from streaming water using the streaming potential. By coupling the generation of electricity to the generation of hydrogen in one process, we aim to increase efficiency as well as provide energy in an alternative storable form.

In your Ph.D. project you will be using nanochannels and nanoporous membranes. It will specifically be your task to optimize the pore wall surface to obtain maximal mechanical-to-electrical conversion efficiencies. You will have to identify the optimal wall material and investigate the influence of different chemical functionalizations. For example, there have been reports that the generation efficiency will strongly increase when the liquid slips past the walls, because this decreases the hydrodynamic resistance. Part of your work will therefore be to chemically functionalize the channel walls to introduce liquid slip. At the same time energy generation will increase with pore surface charge density, which is also influenced by the surface functionalization. Influencing the surface charge density will therefore be another goal.
