TL;DR: The mechanism employed by Larrea tridentata (Creosote bush) to uptake and simultaneously defend against the presence of excess copper has been investigated in this article, showing that creosote takes up or adsorbs copper from the soil in the Cu(II) oxidation state and transports it to the leaves.

TL;DR: In this paper, the role of iron in authentic and synthetic samples of Maya blue using X-ray absorption spectroscopy (XAS) and high-resolution transmission electron microscopy (HRTEM) was investigated.

TL;DR: In this paper, the authors used FT-Raman and FT-IR spectroscopy to demonstrate chemical stability similar to that of the ancient Maya Blue samples, and showed that stable complexes can be synthesized at much higher dye concentrations than used by the Mayas.

TL;DR: The application of multiple synchrotron characterization techniques to two classes of materials defined as 'surface compounds' is reviewed and the 'Maya blue' pigments are identified, based on technology created by the ancient Maya.
