摘要: Abstract Carbonate biominerals are one of the most interesting systems a physicist can study. They play major role in CO2 cycle, they master templation, self-assembly, nanofabrication, phase transitions, space filling, crystal nucleation and growth mechanisms. A new imaging modality was introduced last 5 years that enables direct observation orientation carbonate single crystals, at nano- micro-scale. This is Polarization-dependent Imaging Contrast (PIC) mapping, which based on X-ray linear dichroism, uses PhotoElectron Emission spectroMicroscopy (PEEM). Here we present PIC-mapping results from biominerals, including nacre prismatic layers mollusk shells, sea urchin teeth. We describe various approaches, show these lead to fundamental discoveries formation mechanisms biominerals.
