Application of a handheld Raman spectrometer for the screening of colored secon...
Košek, F; Culka, A; Fornasini, L; Vandenabeele, P; Rousaki, A; Mirão, J; Bersani, D; Candeias, A; Jehlička, JThe São Domingos area (Corte do Pinto, Portugal) represents a large sulfide ore deposit in the Iberian Pyrite Belt that was mined primarily for copper and sulfur in the past. Currently, the deserted mine and mine wastes are the reason for the production of acid mining drainage releasing potentially harmful elements. Because metastable secondary sulfates may temporary sink toxic pollutants, the in situ monitorin...
Micro-Raman spectroscopy and complementary techniques (hXRF, VP-SEM-EDS, μ-FTIR...
Coccato, A; Costa, Mafalda; Rousaki, A; Clist, B; Karklins, K; Bostoen, K; Manhita, A; Cardoso, A; Dias, CB; Candeias, A; Moens, L; Mirao, JIn the framework of the inter-disciplinary KongoKing project, a set of beads from archaeological excavations in the Democratic Republic of the Congo was analysed by means of a minimally invasive, multi-analytical approach based on micro-Raman spectroscopy. The full characterization of the materials, including glassy network, opacifiers and colorizers, was achieved thanks to the combination of data from handheld...
