Energy and environment are the biggest challenges of the 21st century. Nanomaterials with their attractive chemical and physical properties are being explored for their potential in energy, environmental, electronic and magnetic applications. In nanostructured materials, the elemental steps of energy conversion like charge transfer, molecular rearrangement, chemical reactions etc. take place on the nanoscale. Technical energy applications exploiting nanomaterials include harvesting of light, batteries, thermoelectric generation, H storage materials etc. Novel nanoelectronic and nanomagnetic materials are interesting from the point of view of the relationship between microstructural features and the electronic and magnetic properties. Such features include particle size and distribution, chemical inhomogeneities, crystalline defects and crystallographic texture. Technical applications exploiting magnetic nanomaterials include magnetic data storage, sensors, materials for biotechnology, generation and distribution of electric power and other biomedical aspects. Many of our modern technological devices rely on magnetism and magnetic materials like electrical power generators and transformers, electric motors, computers, and components of sound and video reproduction systems.This has led to various opportunities such as improving the quality of magnetic resonance imaging, hyperthermic treatment for malignant cells, site-specific drug delivery and the manipulation of cell membranes. The activities of the group will include synthesis and structural characterization of nanomaterials for electronic, magnetic and energy applications.
