Gerhard Ertl Lecture & Award

Gerhard Ertl Lecture & Award

The Ertl Lecture Award was established in 2008 by the three Berlin universities (Humboldt University, Technical University and Free University) and the Fritz Haber Institute of the Max Planck Society and is awarded once a year. It commemorates former FHI Director Gerhard Ertl's Nobel Prize in Chemistry, which he received in 2007. The prize honours outstanding personalities and researchers in the field of catalysis where Ertl carried out exceptional research for many decades. The prize, sponsored by BASF, includes a one-week research stay at the participating Berlin institutions and a keynote lecture. The winner is typically announced in Spring, the lecture takes place around the December 10th, the anniversary of Ertl's Nobel Prize reception.

Speaker: Dr. Erik T. J. Nibbering

Ultrafast Structural Dynamics of Elementary Water-Mediated Proton Transfer Processes

Proton transport between acids and bases in aqueous solution involves the exchange of protons, rearrangements of hydrogen bonds, and the changes in electron charge distributions of all molecules involved. Progress in the development of ultrafast structurally resolving techniques have enabled to follow in real-time the elementary individual steps in proton transfer that occur on femto- to picosecond time scales. Ultrafast probing in the mid-infrared has provided a wealth of information on hydrogen bond dynamics and proton transfer time scales. Recent progress in soft X-ray spectroscopy of solution phase acids and bases using novel flatjet technology has now made possible to locally probe electronic structure. I will showcase this with examples on proton hydration, and photoacid molecular systems, and indicate how further advances in ultrafast soft X-ray spectroscopy of solution phase proton transfer may be made.
