It is our pleasure to congratulate three of the newest Docteurs de l'Université du Luxembourg! And these defenses all happened in the same very busy last week, so lots of guests to welcome and lots to celebrate.

First up, on 25 August, Xu Ma defended her Ph.D. thesis, "Cholesteric Liquid Crystal Spheres for Visible and Infrared Operation: From Tunable Configurations to Continuous Production".

Secondly, on 27 August, Deniz Avşar defended her Ph.D. thesis, "Encoding Information as Unobtrusive Graphical Patterns Using Cholesteric Spherical Reflectors: From Optical and Materials Challenges to Applications in Robotics".

Finally, to round off the week, Nikolay Popov defended his Ph.D. thesis, "Impact of nonionic stabilizers and ionic solutes on liquid crystal shell stability and defect configuration", on Friday, 29 August.

Häerzlech Gléckwonsch fir eis dräi néi Doktoren!/Félicitations à nos trois nouveaux docteurs!/Congratulations to our three new doctors!
