Despite the large diffusion of natural organic substances in art-historical materials, their
characterization presents many challenges due to the chemical complexity and instability …

Brass is a relatively stable alloy but it tends to tarnish over time due to the interaction with the
atmosphere. Thus, it is rare to observe centuries-old brass objects untouched by the passing …

Optical‐photothermal infrared (O‐PTIR) spectroscopy is a recently developed technique that
provides spectra comparable to traditional transmission FTIR spectroscopy with nanometric …

Medieval texts describe the use of the three-tone system as a pictorial procedure
characteristic of Romanesque art to represent shape and volume. Some Medieval art …

The resin extracted from the species of the Pinus genus (Pinaceae family) is a widely used
material. Primarily, resins are made up of two types of diterpenoids: abietanes and …
