Low energy electron transmission through layered materials and chiral organic films
In this Ph.D. thesis we study the interaction of low energy electrons with thin materials, namely layered materials (graphene, hexagonal boron nitride, molybdenum disulfide) and organic films. At these low energies the quantum mechanical wavelength of the electron wave function is in the order of a…

Conspiracy thinking and social media use are associated with ability to detect deepfakes
Deepfakes zijn video’s die gemanipuleerd zijn om twee personen te verwisselen. Ze kunnen moeilijk te onderscheiden zijn van de originele video’s. In onze studie laten we zien dat mensen die meer complotdenken en mensen die meer gebruikmaken van social media beter zijn in het herkennen van deepfakes.
