Elucidating the Role of Dissolution in CeO Nanoparticle Plant Uptake by Smart Radiolabeling.

The identification of major uptake pathways in plants is an important factor when evaluating the fate of manufactured nanoparticles in the environment and the associated risks. Using different radiolabeling techniques we were able to show a predominantly particulate uptake for CeO nanoparticles in contrast to a possible uptake in the form of ionic cerium.

Evaluating the cytotoxicity of palladium/magnetite nano-catalysts intended for wastewater treatment.

Palladium/magnetite nanoparticulate catalysts were developed for efficient elimination of halogenated organic pollutants from contaminated wastewater. Particle recovery from treated water can be ensured via magnetic separation. However, in worst-case scenarios, this catalyst removal step might fail, leading to particle release into the environment.

Highly active Pd-on-magnetite nanocatalysts for aqueous phase hydrodechlorination reactions.

Nanoscale catalyst particles are already in focus as excellent tools in catalytic processes and intensive research is currently optimizing their performance. As known from nanosized metal particles, nanocatalysts have the potential of very high reaction rates due to their high specific surface areas and low mass transfer restrictions. In this study, we generated extremely active palladium catalysts on the basis of colloidal magnetic carriers.

[Aspects of animal welfare and species protection in the international trade of ornamental fish and air transport to Germany].

The number of ornamental fish kept in German aquariums is rising, but the supply of offspring is not sufficient to meet the needs of the fish enthusiasts. Therefore millions of ornamental fish from foreign countries are being imported to Germany. This provokes a number of new problems regarding the protection of species and the animals' welfare during transportation.
