Participation in the Following Priority Programs (SPP)
SPP 1681: Field controlled particle matrix interactions: synthesis multiscale modelling and application of magnetic hybrid materials
The use of magnetic fields is an external stimulus for the control of material properties, which is of considerable technical interest, since magnetic fields can easily be generated and controlled. Recently, significant progress has been made in terms of both synthesis and modeling and feature analysis of magnetic hybrid materials. The program thus spans the field of problems from the synthesis of magnetic hybrid materials over the characterization of material behavior and microstructure and their theoretical description towards technical and medical applications. The result is a highly interdisciplinary field of research that extends from chemistry to materials science, experimental and theoretical physics and towards engineering sciences and medicine.

SPP 1613: Fuels Produced Regeneratively Through Light-Driven Water Splitting
If solar energy turns into electric current, one needs an expensive storage technology. An alternative: When splitting water, chemical energy is converted into oxygen and hydrogen and later becomes re-available in a fuel cell. In priority program 1613 scientists search for suitable materials to produce regenerative fuels by light-driven water splitting. Also, the role of nanoparticles and catalysts is analyzed in order to develop new technologies later.
SPP 1599: Caloric Effects in Ferroic Materials: New Concepts for Cooling
The recent discovery of giant entropy changes associated with ferroelastic phase transformations promises higher efficiency for future refrigerants. Furthermore, because the refrigerant is in a solid state, the technology completely eliminates the need for high global-warming potential halofluorocarbon refrigerants. In order to accelerate research on ferroic cooling DFG decided to establish the priority program SPP 1599. It will address the major challenges for introducing ferroic materials in practical cooling applications.
SPP1538: Spin Caloric Transport
The aim of the Priority Program “Spin Caloric Transport“ (SpinCaT) is to develop the new research field of caloric effects in spin transport. The program is designed to run for six years and will focus on four priority areas:
- spin caloric effects and spin mediated heat transport in planar geometry
- thermal spin-based conductivities across interfaces in nanopatterned magnetic devices
- spin currents induced by large temperature gradients
- materials for spin caloric applications
To focus the activities, materials to be investigated should show strong magnetic interactions such as magnetic order or large spin orbit coupling. The aim of the program is to explore effects at room temperature.
SPP 1459: Graphen
The aim of the Priority Programme is to promote the understanding and control of the properties of graphene with the vision to establish a basis for new, graphene-based electronics. In a total of 38 projects, the scientists concentrate on aspects like the synthesis of high quality graphene, its interaction with other materials and contacts and the construction of functional demonstrators.
SPP 1391: Ultrafast Nano-optics
Priority program 1391 involves the interaction of coherent broadband excitations with nanostructures. The subject areas dealt with here involve coherent control, propagation, nonlinear response, and nanoantenna. Studies are being carried out at the University of Duisburg-Essen on spatiotemporal dynamics and the nonlinear interaction of plasmon-polariton waves with self-assembled silver islands through the use of nonlinear photoemission microscopy.
SPP 1386: Nanostructured Thermoelectric Materials
The researchers involved in priority program SPP 1386 “Nanostructured Thermoelectric Materials" are tasked with developing thermoelectric systems using nanostructured materials that in the long term are 50-200% more efficient than conventional materials. The development of more efficient thermoelectric materials would open up completely new opportunities in the field of energy technology, such as through the direct usage of waste heat in combustion engines, while simultaneously reducing CO2, and in energy self-sufficient sensors. This priority program combines questions from the areas of physics, nanotechnology and microsystems, measurement and energy technology, and materials science.
SPP 1327: Optically-Generated Sub-100 nm Structures for Biomedical and Technical Applications
The objective of this priority program is to comprehensively describe the basic physical, optical, and chemical processes that occur in the nanostructuring and nanofunctionalization of materials and surfaces using non-linear photonic methods. The structures being investigated are limited to sub-100 nm and are produced using ultrashort laser pulses (picoseconds, femtoseconds, attoseconds).
SPP 1313: Biological Responses to Nanoscale Particles
In priority program 1313, the basic interaction processes between nanoparticles and biological systems at cellular and molecular level are examined. This includes clarifying the way in which nanoparticles are transported across biological membranes and other phase boundaries, interactions with proteins and cell constituents, as well as the effects on biological functions. In these investigations, the latest methods for the production and characterization of nano particles as well as their detection and localization in biological systems are applied.
SPP 1285: Semiconductor Spintronics
The objective of this priority program is to investigate the physical bases for future semiconductor electronics using the “spin” degree of freedom through intensive collaboration between theoretical, experimental and material-oriented groups. For the first phase, the focus is on combining theory, experimental physics, and materials science to create the bases for spintronic components. In addition to basic research, the second phase will focus on strengthening the engineering component in order to place greater emphasis on the development of new types of components and quantum-mechanical circuit structures.
