Visualizing the dynamics of quasicrystalline and periodic solid-liquid interfaces via fast 4D X-ray tomography

Our research proposal seeks to delve into the dynamics of quasicrystal (QC) growth, unveiling the fundamental principles that govern their formation. Decagonal
QCs in particular possess an aperiodic plane and a periodic axis perpendicular to this plane. By comparing growth dynamics in aperiodic and periodic directions,
we can place QCs in the same plane of analysis as classical periodic crystals, at least in terms of kinetic properties. Here, we intend to utilize sub-second X-ray
microtomography at beamline ID19 to measure the interfacial dynamics for the solidification of QCs on a timescale that has not been measured yet to the best of
our knowledge.
