Colloidal semiconductor nanocrystals are versatile nanomaterials, whose properties are determined by their size, shape (quantum dots and nanorods, nanosheets, nanowires), composition, and compositional profile (i.e., single component, gradient or homogeneous alloy, doped, heterostructured). Heterostructured semiconductor nanocrystals (hetero-NCs) are particularly attractive, since they allow the spatial localization of photogenerated charge carriers to be manipulated by controlling the band offsets between the materials that are combined at the heterointerface. This has a dramatic impact on... Read more

Solar energy driven processes with H2O and CO2 as basic feedstocks can produce ‘‘solar fuels’’ that could substitute their fossil based counterparts. This presentation summarizes the main findings of techno-economic research on systems that can generate different types of fuels with renewable energy as starting point. These ‘‘renewable fuels’’ could potentially play a key role in future energy systems, both as a storage medium in the power sector and as an energy carrier in e.g. the transport sector, or deliver fundamental building blocks for the chemical industry.
Stellarators, the twisted siblings of the axisymmetric fusion experiments called tokamaks, have historically suffered from confining the heat of the plasma insufficiently compared with tokamaks and were therefore considered to be less promising candidates for a fusion reactor. This has changed, however, with the advent of stellarators in which the laminar transport is reduced by shaping the magnetic field accordingly. As in tokamaks, the turbulent transport remains as the now dominant transport channel.
