We have far more oil, coal and gas than we can safely burn. Tackling global warming implies that we must leave most of our fossil reserves in the ground. This will require a completely different way of running our economy, shifting away from liquid fuels for mobility and deriving our chemicals and materials as much as possible from renewable resources. I will discuss the challenges and opportunities that arise from these changes and the enabling role that catalysis can play in the energy transition using examples of our own research.

Illumination of a slurry of (micrometer sized) semiconductor particles in an aqueous phase solution of a metal salt, often results in deposition of well-defined metal(oxide) nanoparticles on the surface of the semiconductor particles: this phenomenon is generally known as photodeposition. In this lecture I will discuss the effect of process conditions, focusing on the role of a so-called sacrificial donor, on the oxidation state and morphology of Pt nanoparticles which are obtained when using photodeposition.

Strong presentation skills are a key to success for engineers, scientists, and others, yetmany speakers are at a loss to tackle the task. Systematic as they otherwise can be in their work, they go at it intuitively or haphazardly, with much good will but seldom good results. In this talk, Dr Doumont proposes a systematic way to prepare and deliver an oral presentation: he covers structure, slides, and delivery, as well as stage fright.

(note the slightly later time of this seminar) An electron in a solid has three attributes: charge, spin, and orbital. The orbital represents the shape of the electron cloud in a solid. In magnetic metal oxides with anisotropic-shaped d-orbitals not only the Coulomb interactions are of importance, but also the quantum exchange energy is crucial for understanding their properties. The orbital degree of freedom causes a variety of phenomena through strong coupling with charge, spin, and lattice dynamics; which determine the catalytic activity of magnetic oxides.

The 20th Workshop on the Exploration of Low Temperature Plasma Physics (WELTPP-20) will be held on the 30th November and 1st December 2017 at the old convent Rolduc in Kerkrade. This workshop is intended for active scientists working in the field of low temperature plasma physics and usually covers low up to atmospheric pressure plasmas, modelling and diagnostic techniques.
