In this talk, Prof Marc Koper Link opens in a new windowjoins us form Leiden University, NL, to discuss the mechanism of the simplest electrocatalytic reaction, namely hydrogen evolution, in both acidic and alkaline media. In addition to the hydrogen binding energy, we show that in alkaline media at least two other activity descriptors are relevant: OH or oxygen binding energy of the catalyst surface, and local cation concentration near the electrode surface. Both parameters are expected to influence the rate of the first (Volmer) step in alkaline media. At higher current density, hydrogen evolution becomes dominated by bubble formation and removal. We show that thermal and solutal Marangoni forces due to surface tension gradients in the electrolyte determine the local fluid dynamics and thereby impact bubble coalescence and removal.

This is a departmental lecture for all students and staff. Please come along. Tea, coffee and refreshments will be provided from 12:45 on the Science Concourse.

Science Facilities Roadshows

Gibbet Hill – 27th April and Main Campus 20^th June

Looking to learn more about the cutting-edge scientific facilities at the University of Warwick? The Science Facilities Roadshow is a unique opportunity to discover how the facilities at the University of Warwick can help enable your research and foster new collaborations.

These events offers staff and students the chance to engage with facility managers and technical specialists across a wide range of facilities from Gibbet Hill to the Main Campus. You'll have the opportunity to attend 8 short facility talks, followed by networking over coffee and cake in the atrium afterwards.

The first Roadshow is in the IBRB, Gibbet Hill on 27th April 2-4 pm, with a second being held on the main campus on 20th June. Please visit our website for more information, and to register:

Prof David Wales, University of CambridgeLink opens in a new window, joins us as a guest speaker. This is a departmental lecture for all students and staff. Please come along. Tea, coffee and refreshments will be provided from 12:45.

Abstract

The potential energy landscape provides a conceptual and computational framework for investigating structure, dynamics and thermodynamics in atomic and molecular science. This talk will summarise new approaches for global optimisation, quantum dynamics, the thermodynamic properties of systems exhibiting broken ergodicity, and rare event dynamics. Applications will be presented that range from prediction and analysis of high-resolution spectra, to coarse grained models and design principles for self-assembly of mesoscopic structures, with recent results for machine learning landscapes.
