Announcement Start Up Funding

Start-up funding

 

Within the SPP1959, young post-doctoral researchers have the opportunity to get funding for their own, collaborative project idea. A collaboration between young post docs from different SPP1959 projects, who have not worked on a joint project so far, is required for application. Their project idea is reviewed by the programme committee and if applicable recommended for funding.

The first project, entitled "Electric and magnetic field effects on solid state synthesis of BaTiO3 and FeTiO3 from binary oxide mixtures", is now going to be funded from the SPP1959 coordination fund.

Abstract:

In this project, synthesis of two oxide ceramics namely BaTiO3 and FeTiO3 will be probed by two alternative methods (1) electric field/current assisted synthesis, the process also known as reactive flash sintering (RG Guillon) and (2) magnetic field assisted sintering of preceramic homogenates obtained from single-source molecular precursors (RG Mathur). This will be followed by comparative analysis of the magnetic properties (RG Gutfleisch) and phase purity of the target ceramics. Moreover, the effects of external magnetic and electric fields on microstructure evolution, grain orientation and phase segregation will be investigated to understand the field effects (both electrical and magnetic) on phase evolution and grain growth phenomena.

Specific technical objectives of this collaborative effort within SPP1959 are:

  1. Evaluation of process parameters enabling synthesis of single-phase FeTiO3 and BaTiO3 under field and no-field conditions.
  2. Contrasting the field effects in the flash sintering of two crystalline powders (BaO & TiO2 and Fe2O3 & TiO2) and an amorphous gel with pre-formed mixed cation bonds (-Fe-O(H)-Ti- and -Ba-O(H)-Ti-)
  3. Microstructure evolution and phase segregation: role of magnetic vs. non-magnetic ions during nucleation and grain growth.
  4. Investigations on photo-electrocatalytic performance: Role of processing parameters on the performance of the obtained materials.
