Dr. M. Heggen: What’s your research all about?

More than 2,000 scientists work at Forschungszentrum Jülich. At more than 80 different institutes, they search for new insights in their respective fields and often go unconventional ways. Year after year, they publish their results in thousands of articles, initiate research projects or file new patents. Reason enough to look straight at the laboratory or the desks of individual researchers and ask: what’s your research all about? This is exactly what we will be doing here in the future: presenting in brief the areas of responsibility of some clever minds who create new knowledge every day on the research campus.

“Precious, shiny metals are the focus of my research – but only in tiny quantities because I look at individual atoms. Expensive platinum, for example, which is used as a catalyst in fuel cells. With my colleagues, I look for inexpensive alternatives. We use high-resolution electron microscopy for this purpose. We could thus show that the arrangement of platinum and nickel in specially shaped nanoparticles is decisive for their performance. As a result, catalysts were designed that are ten times more efficient than pure platinum – and thus significantly cheaper.”
