Topic 1: Synthesis and Phase Control
Influence of magnetic field on film growth and topography.
Electric and magnetic field processing are effective tools to control the structural and functional properties of materials. Therefore the impact of magnetic and electric fields and current on defects, phase transformation, solid state reactions and microstructure is investigated in this topic.

Topic 2: Densification and Coarsening
Field assisted sintering of a high temperature material.
Technologies, such as electric and magnetic field assisted sintering, offer the possibility to produce materials that are extremely difficult, if not impossible, to obtain by conventional methods. The impact of fields on densification, microstructure and material properties is investigated here.

Topic 3: Mechanical Deformation
Influence of current on mechanical deformation.
This topic focuses on the electro- and magneto-plastic effects. The use of fields can indeed change the mechanical behavior of solids dramatically and can potentially reduce processing time and temperatures.
