Abstract (englisch):

Technical relevance of diverse magnetic nanoparticles is rising steadily in numerous and distinct fields. Their application potential is increasing strongly in the field of tumor treatment, for instance, where iron oxide nanoparticles are used to provide magnetic hyperthermia procedures or targeted drug delivery therapies. Advanced quality criteria such as high purities or narrow particle size distributions can only be achieved to a certain extent by the synthesis process. The supply of rare earth particles such as holmium or dysprosium is as well essential for many 21st century technologies such as luminescent material, electronic, catalyst, battery and alloy technologies. Efficient recycling and waste management of such technology-critical materials is crucial as the demand is expected to further grow rapidly within the next few years. Thus, in order to remove undesirable contaminants and/or achieve an improvement regarding particle size distribution, it is often vital to perform a size fractionation after the synthesis process or as part of a recycling process.

For the particle size range in the nanometric scale, however, fractionation processes encounter technical difficulties with only limited solutions discovered, yet. ... mehr
