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.

The light-driven water splitting reaction to generate molecular hydrogen and oxygen is one of the most promising processes for producing clean fuels. In the approach we are following we attempt to construct a photoelectrochemical (PEC) cell based on molecular components. The two half reactions, water oxidation (anode-side) and proton reduction (cathode-side), both require their own specialized catalysts, linkages, chromophores, and electrode materials. Initially, these components are made and studied separately, first in solution and subsequently as integrated part of the electrode.

Many layered materials can be mechanically exfoliated to atomically thin sheets, the most famous being graphene. This opens the possibility to stack different layer types together to form materials with novel properties: van der Waals (vdW) systems. The extent to which vdW systemsdiffer from the mother materials is governed by the interaction between the different layers. Here, we investigate interlayer interactions using several novel techniques developed in our lab. At the basis is a low-energy electron microscope (LEEM).
