Nucleation and growth in nanomaterials

Academic head of project management: Erdélyi Zoltán

  • Title of project: Nukleáció és növekedés nanoanyagokban
  • Type of grant: OTKA-NF
  • Description: Due to the complexity of the problem, until now there has been no systematic investigation into the effect of stresses on the diffusion-reaction. We plan calculations in the framework of Stephenson’s model, both for planar and spherical geometries, considering vacancy sinks and sources. Stress development and relaxation may result in contraction or expansion of matrixes in a nanolayered material. We will develop neutron standing wave technique (NSW) at the Budapest Neutron Centre and study these effects by using the NSW and synchrotron standing wave technique modified for this purpose. Also for deeper understanding of diffusion-reaction processes, we intend to investigate the formation of ordered nuclei in ordering systems and in which an ordered phase and a solid solution with restricted solubility are in equilibrium.
  • The duration of the project: April 1, 2012 – December 31, 2016
  • Actual total costs: 81.686.000 (HUF)
  • Type of research: Basic
