The properties of a clinical LINAC are investigated for a study of photoactivation cross-sections slightly above the neutron threshold. As an example, the photoactivation of a tiny amount of gold by the Au(γ,n)196197Au reaction has been measured. Th

The most widely prescribed antidepressant, fluoxetine (FLX), is known for its antioxidant and anti-inflammatory effects when administered post-stress. Few studies have evaluated the effects of FLX treatment when chronic stress has induced deleterious

Sections of interplanetary dust particles (IDPs) have been analyzed with proton-induced X-ray emission (PIXE) and scanning transmission ion microscopy (STIM) in order to determine trace element contents and distributions on a micrometer scale as well

Geosiphon pyriforme represents the only known endosymbiosis between a fungus, belonging to the arbuscular mycorrhizal (AM) fungi, and cyanobacteria (blue-green algae). Therefore we use Geosiphon as a model system for the widespread AM symbiosis and t

Brassica juncea L. is a high biomass producing crop plant, being able to accumulate Cd and other heavy metals in their roots and shoots. It is a good candidate for efficient phytoextraction of heavy metals – such as Cd – from polluted soils. PIXE

We developed a new technique to determine the impact position of single pencil beams in the image plane with an accuracy of 0.2 μm. This technique bases on the overlapping of secondary electron images from a 1000 mesh grid. The measurements themselv

Some aspects of quantitative analysis of biological samples – including a review of the relevant literature – are discussed. Special emphasis is put on the accuracy of trace elemental results despite severe sample damage which occurs during analy

Geosiphon pyriforme is a unique endosymbiotic consortium consisting of a soil dwelling fungus and the cyanobacterium Nostoc punctiforme. At present this symbiosis becomes very interesting because of its phylogenetic relationship to the arbuscular myc

Graphite intercalation compounds combine low density with high electrical conductivity. These physical properties makes these compounds interesting as components of carbon epoxy composites, but the high reactivity of graphite intercalation compounds
