Thin porous metal oxide films offer unique physical, electrical and magnetic properties with applications in various fields including catalysis, gas sensing and separation, power storage and generation as well as biology and medicine. Currently known synthesis techniques for metal oxide films with templated porosity (e.g. dip-coating, spin-coating) show significant limitations when they are faced with large substrates and/or substrates with a micro-structured surface.

Cytokinins are plant hormones involved in cell division, shoot meristem and leaf formation, chloroplast biogenesis, and senescence. The development of agonists and antagonists with a particular physiological effect is useful in mechanism-of-action studies of biologically active natural products. The potent naturally occurring cytokinin N6-isopentenyladenine served as the basis for initial structure-activity studies.

Processing of the amyloid precursor protein (APP) by ß-and γ -secretases leads to the generation of amyloid-ß (Aß) peptides, which are the toxic agents in the pathogenesis of Alzheimer`s Disease. γ –secretase cleaves at variable sites producing Aß peptides with different C-termini, of which particularly Aß42 contributes to cytotoxicity and amyloid accumulation in Alzheimer Disease.

Background
Quantum Cascade Lasers (QCLs) are currently the best electrically-pumped sources of Terahertz (THz) radiation regarding output power, linewidth, operating temperatures and efficiency. THz QCLs offer a wide field of applications ranging from astrophysics and security screening to ultrafast spectroscopy in chemistry or biology. For all these applications THz QCLs which can operate at moderate temperature are desired.
