Hellen defends her thesis on Friday

MSc Hellen Santos will have her doctoral dissertation on Friday 15th of December at at 12 o’clock in the lecture hall Arcanum 1.

The title of the thesis is “Halogen hectorites: Smectites designed to luminesce” and concerns design and preparation of these synthetic clay minerals and the studies how they could be used as optical materials.
