Reflectance spectral imaging is a powerful tool for the non-invasive study of cultural heritage objects. Particular visible to short wave infrared (400-2500 nm) features are linked compositional information. Spectral images can hence be used generate useful chemical maps. However, in case complex mixtures, global shape reflectance spectra pure materials affected by presence other absorbing materials. While studying heterogeneous polychromatic surfaces which same material found different...
The identification of <italic>Justicia spicigera</italic> in the <italic>Codex Borbonicus</italic> by Raman spectroscopy motivated development a multi-analytical techniques approach to broaden physico-chemical knowledge regarding this traditional dye source.
Ultraviolet visible (UV–Vis) fluorescence spectroscopy is widely used to study polychrome objects and can help identify the nature of certain materials when they present specific fluorescent properties. However, given complexity stratified heterogeneous under study, characterization an intrinsic related a constituent (a pigment or binder composing paint layer for example) not straightforward, recorded raw data need be corrected number effects that influence detected spectral distribution....

Abstract In contrast to most butterflies harboring opaque wing colorations, some species display large transparent patches on their wings. Wing transparency, which entails a dramatic reduction of pigmentation, raises the question potential costs for vital functions, such as thermoregulation, especially along climatic gradients. The thermal melanism hypothesis posits that darker colorations should be favored in colder environments, enables them absorb more radiation and maintain body...
