"...A recent study explored how spectroscopy can be applied to stamp collecting, also known as philately. A couple of researchers from the Universidad Nacional de Córdoba in Argentina proposed a new approach that they claim can improve the authentication of postal stamps. This study, which was published in the journal Spectrochimica Acta Part B: Atomic Spectroscopy, investigates the effectiveness of using energy-dispersive inelastic X-ray scattering (EDIXS) to differentiate between types of inks used in cancellation marks..."
