Ulrike Diebold Receives Adamson-Award

American Chemical Society ACS honours her research on metal oxides.

29.5.2013 | Metal oxides have highly diverse properties - they can be used as catalysts or protective layers, as insulators or superconductors. For her research in this promising field, Prof. Diebold was awarded the 2013 Arthur W. Adamson Award for Distinguished Service in the Advancement of Surface Chemistry.

Prof. Ulrike Diebold
Ulrike Diebold is an experimental surface scientist with a focus on metal oxide surfaces. After all, most metals are oxidized in the ambient atmosphere, so it is, in fact, the oxide surface that deserves most attention. Furthermore, metal oxides exhibit an extremely rich variety of chemical and physical properties. While some metal oxides are chemically so inert that they are used as corrosion protection layers, others prove to be active and selective catalysts. The best electrical insulators belong to the class of metal oxides - yet also the most-promising high temperature superconductors. Due to this high tunability of their properties, metal oxides are used in many different technical areas – as gas sensors, catalysts, in solar cells, batteries, etc.

In virtually all applications, the surfaces of metal oxides play a major, and often the dominant role. Hence a more in-depth understanding of the surface of metal oxides surface is key to understanding and improving device performance. In her research lab, Prof. Diebold uses Scanning Tunnelling Microscopy (STM), in combination with surface spectroscopic and diffraction techniques, to unravel the atomic-scale geometry, electronic structure, and reactivity of surfaces at the atomic scale. STM allows to investigate processes at surfaces in a direct manner, as well as on a molecule-by-molecule basis. So far she has mostly concentrated on semiconducting binary metal oxides such as TiO2, SnO2, ZnO, or Fe3O4.

Already in 1993, Prof. Diebold studied metal oxides at Tulane University in New Orleans. Her research on titanium oxide, an important component of photocatalysis, attracted notice at that time. In 2010, she returned to the Vienna University of Technology (TU Wien), where she had obtained her PhD degree in 1990. Two years after her return to Vienna, she received a grant of the European Research Council ERC for further research on metal oxide surfaces.

Each year, the American Chemical Society confers the Arthur W. Adamson Award to a researcher with outstanding achievements in surface chemistry. The award consists of a medallion, a certificate and 5,000 US dollars prize money. Last month, Prof. Diebold received the award personally in a ceremony at the ACS National Meeting in New Orleans.   (© Vienna University of Technology, AcademiaNet)

  1. ‘Scientists are still human beings with presuppositions about sex differences’

    Science is meant to be objective but sometimes the personal bias of the researcher gets in the way. To find out more, AcademiaNet went online for a conversation with Associate Professor Malin Ah-King from Stockholm University, whose work sits at the intersection of gender studies and evolutionary biology.

  2. Petra Ahrweiler and Elisabeth André secure funding from Volkswagen Foundation for artificial intelligence project

    The project aims to improve AI technologies for social welfare systems.

  3. Seismology project headed by Prof Céline Hadziioannou granted with €4 million

    The project will improve predictions of natural disasters, such as landslides.

  4. Learning from feminism: Ericka Johnson on the prostate and insufficient toilets

    Over the last decades women have fought for change and a more gender-balanced society. We still have a long way to go. Professor Johnson from the Linköping University spoke to us about feminist technoscience, public infrastructure and the problem with binary categories in research.

  5. Anu Noorma elected new head of the Estonian Research Council

    The professor of physics starts her five year term on April 1st.
