Project title:

NEW NANOSTRUCTURED VITREOUS SYSTEMS WITH POSSIBLE APPLICATIONS IN THE IMMOBILIZATION OF NUCLEAR WASTES

Project director:

Prof.dr. Eugen CULEA, Technical University of Cluj-Napoca

Duration of the project:

1 May 2009- 30 April 2011
Financial support:

Project targets:

-Preparation of some samples in the GeO-PbO and TeO-PbO vitreous systems doped with Gd, Eu, Er and Ce ions;

-Obtaining of structural information concerning the above mentioned systems by investigations using X-ray diffraction, IR, UV-Vis, Raman and EPR spectroscopies and magnetic susceptibility measurements.

Human resources:

         The project research team is composed of Prof.dr.Culea Eugen -project director- 2 postdoc researchers and a master degree student:

1. Dr.Pascuta Petru
2. Dr.Rada Simona
3. Culea Nicolae Eugen
   

         During the project the postdoctoral researchers will improve their professional experience in using some structural investigations techniques (i.e., XPS spectroscopy) at the University of Osnabruck, Germany.

Equipments:

         Due to the financial support obtained by the project IDEI 183/2009, during the year 2009, at the Department of Physics of the Technical University of Cluj-Napoca some accessories for the EPR spectrometer were acquisitioned.

Dissemination of results:

         The results obtained during the year 2009 were published in some scientific journals or were reported at international conferences:
