Since 2014 I have been a doctoral student in Prof. Dr. Fiz. Ioan Ardelean’s team in the NMR diffusometry and relaxometry laboratory, part of the Physics and Chemistry Department at the Technical University of Cluj-Napoca, Faculty of Materials and Environmental Engineering.
So far I have worked on NMR relaxometry experiments on cement based materials (both gray and white cement) in low magnetic fields.
I use silica nanoparticles as mineral fillers and am studying their effects on the properties of cement based materials, especially on their porosity.
Together with the team, I have managed the following:
