KNOWLEDGE DISSEMINATION

Editor’s choice in Journal of Cultural Heritage, Volume 47, 2021

Identification of dyes is of great importance for the protection of textiles artefacts, as well as for further understanding the manufacturing process of ancient dyes. Moreover, the evaluation of degradation status can help conservators to reconstruct the original appearance of historical textile objects and predict the stability of their colors.
Natural organic dyes on textile are usually detected through molecular analytical methods. In particular, liquid chromatography (LC) and gas chromatography (GC) have been widely used in the dye analysis with high accuracy. However, they are invasive methods, as they are based on the analysis of organic extracts.

Recently, non-invasive methods based on spectroscopy technology, such as reflectance spectroscopy and fluorescence spectroscopy, received great attention. Reflectance spectroscopy is used for the characterization of paint films and pigments. In addition, Kubelka-Munk’s theoretical reflectivity of diffuse medium provides chances to quantitatively analyze mixtures of pigments by reflectance spectroscopy. When the scattering coefficient is independent of the wavelength, the typical absorption spectrum measured by the reflection can be used as a substitute indicator for the actual absorption spectra.

THIS WEEK'S HIGHLIGHTS

Process optimization is necessary for the design and development of materials with new performances and high functionality, able to operate under aggressive conditions such as those of the waste energy plants, the systems for solar cells, the fossil fuel systems or the innovative nuclear systems (subcritical reactors, Generation IV reactors).

The research activity concerns the development and application of optical/spectroscopic techniques for chemical and morphological characterization of nanoparticles in aerosols.
The following techniques are currently used:

  • Laser-Induced Incandescence (LII)
  • Laser-Induced Breakdown Spettroscopy (LIBS)

A relevant part of the research activity is focused on the optimization of innovative "wet chemistry" synthesis processes through three general approaches:

  1. hydrothermal
  2. miniemulsion
  3. nucleation and growth from solution

A first approach is based on the combination of hydrothermal treatments with oxalates co-precipitation. This approach has been used for the production of nanomaterials with interesting magnetic properties, in particular ferrites and manganites, with crystallite domains with average sizes ranging between 5 and 50 nm.
