Confocal Raman microscopy for in depth analysis in the field of cultural heritage
Autor: Jana Striova, Emilio Castellucci, Angela Zoppi, G. Lorenzetti
Publikováno v: Journal of Molecular Structure. 993:97-103
In the field of cultural heritage, the main concern when a sample is analyzed is its safeguard, and this means that non-destructive techniques are required. In this work, we show how confocal Raman microscopy (CRM) may be successfully applied in the

Publikováno v: Journal of Raman Spectroscopy. 41:1550-1555
Terra sigillata is certainly the most famous fine ware of the Roman period, and for this reason it has been a subject of interest for both the archeology and archeometry communities. X-ray diffraction studies showed systematic differences in the mine

Autor: Angela Zoppi, Emilio Castellucci, Cristiana Lofrumento, N. F. C. Mendes
Publikováno v: Analytical and Bioanalytical Chemistry. 397:841-849
One degradation phenomenon that occurs in artworks is the formation of metal oxalates on their surfaces. In order to gain insight into the inclination of pigments to produce oxalates, nine pigments including Na, Ca, Fe, Pb and Cu cations were selecte
