Motivation: For years, silicon has been successfully used as the standard substrate material for the fabrication of penetrating neural probes that perform electrical recording as well as stimulation of single or multiple neuronal cells in vivo. Nevertheless, the mechanical mismatch between the stiff silicon and the surrounding soft tissue enhances acute inflammatory responses [1] and hampers the long-term stability and performance of such implants due to glial scarring as a consequence of foreign body responses [2].

A major criterion in the final disposal of nuclear waste is to keep possible changes in the geosphere due to the introduction of radioactive waste as small as possible and to prevent any escape into the biosphere in the long term. The Federal Office for Radiation Protection (BfS) has therefore established limit values for a number of nuclides [...]

Bei der Entwicklung der Hochtemperaturbrennstoffzelle mit planarer Bauweise werden gasdichte Materialien als Lote zur Abdichtung der Zelle benötigt. Die Bildung von unerwünschten Reaktionsphasen an den Grenzflächen der Brennstoffzelle kann zur Degradation der Zelle beitragen [...]

In energy conversion systems for electric vehicles with fuel cells for generating electricity for the power train, different fuels can be used as energy carriers. These fuels can be converted into hydrogen-rich fuel gas either in a process tailored to the respective fuel or in a largely unified process accounting for the specific requirements of the fuel used.

Terpyridine derivatives reveal rich coordination chemistry and are frequently used to construct reliable metallo-supramolecular wires, which are promising candidates for optoelectronic or nanoelectronic devices. Here, we examine especially the terpyridine/electrode interface, which is a critical point in these organic/inorganic hybrid architectures and of utmost importance with respect to the device performance.
