Method maps reddish pigment in fossil
C&EN Global Enterprise, 2019Two types of melanins are involved in coloration of animal skin and fur. Eumelanin is associated with black and dark brown hues, whereas pheomelanin is associated with lighter reddish-brown shades. Knowing how these pigments are distributed in fossilized soft-tissue remains can help scientists understand what extinct animals looked like.

Near-Infrared Luminescence of Cadmium Pigments: In situ Identification and Mapping in Paintings
Applied Spectroscopy, 2011A comprehensive study of the luminescence properties of cadmium pigments was undertaken to determine whether these properties could be used for in situ identification and mapping of the pigments in paintings. Cadmium pigments are semiconductors that show band edge luminescence in the visible range and deep trap luminescence in the ...

Developing Macro-Raman Mapping as a Tool for Studying the Pigment Distribution of Art Objects
Analytical Chemistry, 2021Raman spectroscopy is a well-appreciated technique in cultural heritage research for its ability to obtain molecular information nondestructively. During Raman mapping experiments, advantage is taken of the excellent spatial resolution of the approach, allowing to visualize the spatial distribution of the molecules. In the current research, macro-Raman

Mapping pigment distribution in mud samples through hyperspectral imaging
SPIE Proceedings, 2015Mud samples collected from bodies of water reveal information about the distribution of microorganisms in the local sediments. Hyperspectral imaging has been investigated as a technology to identify phototropic organisms living on sediments collected from the Texas Coastal Bend area based on their spectral pigment profiles and spatial arrangement.

Raman mapping study of the pigments in the dancheong of Korean traditional buildings
Journal of the Korean Physical Society, 2017Korea experienced a tragic loss of most of the Sungnyemun building in an arson attack in 2008. Few scientific records of the pigments originally used in the Korean national treasure exist, thus, the restoration of Sungnyemun was a serious failure. Because the Raman spectroscopic method has the advantage of analyzing the pigment phases in a simple ...
