Arianna's Palette: A Diagnostic Study of the Painting Walls of the Domus of Arianna in Pompeii
ABSTRACT The House of Arianna, also known as the House of Colored Capitals, represents, with its 1700 m2 of floor space, one of the most majestic examples of a residence within the Pompeii archaeological site. The research developed within the project “Cultural Heritage Active Innovation for Sustainable Society—CHANGES” reports the outcomes of the ...

Thermal analysis of goethite [PDF]
Differential scanning calorimetry shows two endotherms at 75 and 225°C for synthetic goethite. The latter endotherm is strongly asymmetric on the low temperature side. The endotherms were attributed to the loss of water and the dehydroxylation of the goethite.

Phase diagram of hard board like colloids from computer simulations [PDF]
The rich mesophase polymorhism and the phase sequence of board-like colloids depends critically on their shape anisometry. Implementing extensive Monte Carlo simulations, we calculated the full phase diagram of sterically interacting board-like particles,

Abstract This research aimed to investigate the effect of calcination temperature on the phase, morphological and optical properties of iron oxides: hematite (α‐Fe₂O₃), magnetite (Fe₃O₄) and goethite (α‐FeOOH), synthesised by co‐precipitation, aiming at their applications as pigments.

Visible and near infrared spectroscopy in soil science [PDF]
This chapter provides a review on the state of soil visible–near infrared (vis–NIR) spectroscopy. Our intention is for the review to serve as a source of up-to date information on the past and current role of vis–NIR spectroscopy in soil science.

ABSTRACT Thin ferruginous sandy crusts are common on top of sandstone beds in the Early Permian post‐glacial deposits of the Paraná Basin in southern Brazil. These crusts usually preserve wrinkle structures, suggesting that they might be a product of microbial mediation.
