At the heart of these scanners are materials called scintillators, which light up when hit by radiation. In his PhD research at Aarhus University, Simon Peter Slot Jessen studied how new nanomaterials could be used to build better, faster scintillators, using laser light to mimic real-world ionizing radiation.

Using ultrafast X-ray pulses, researchers found that the material’s surface reacts differently than the bulk when its orbital order is disturbed. These results challenge the idea that light-induced changes happen uniformly and suggest that the path from order to disorder is shaped by local differences inside the material.

But producing them sustainably and without rare earth elements remains a major challenge. In his PhD project at Aarhus University, Priyank Shyam explored how to design and optimize ferrite-based magnets that are both effective and rare-earth-free. His work combines synthesis, structural characterization, property measurements, and performance optimization which are all key pillars of modern materials science. Laura Rammelt 1752526800 1752526800
