The chemical composition of low temperature cofired ceramics (LTCC) allows to locally embed air into sintered substrates by a selective wet chemical etch process. Therefore, LTCC substrate with areas of low permittivity can be created without materia

In this study a promising approach for a novel fuel cell catalyst layer is shown using films of carbon nanotubes (CNTs) formed by the layer-by-layer (LbL) method. A special focus is on the dispensing procedure of CNTs in water what is one of the most
