Black Plastic Identification for Sorting and Recycling With Deep‐UV Raman Spectroscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
We present a deep ultraviolet (DUV) Raman spectrometer for sorting black plastics in recycling. The common identification modality of hyperspectral NIR struggles with black plastics due to strong absorption by the black pigment. By using a 248.6‐nm NeCu laser, we enable stand‐off detection over a conveyor belt while avoiding fluorescence interference ...

Study of Garnets in Hellenistic–Roman Jewellery From the Collections of the Archaeological Museum of Thessaloniki, Greece

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study presents the gemological analysis of 25 garnets from Hellenistic and Roman jewellery in the Archaeological Museum of Thessaloniki using mobile Raman spectroscopy and micro‐EDXRF. The garnets are classified into three geochemical clusters, with notable differences in distribution between Thessaloniki and Pydna, suggesting distinct trading ...

Maximizing Scientific Exploitation of Raman Spectroscopy With A.C.M.E. (Atmospheric Chamber for Measurements in Environment)

open access: yesJournal of Raman Spectroscopy, EarlyView.
Simulated planetary gas detection using the A.C.M.E. chamber and a novel hollow‐core fiber Raman sensor. Controlled atmospheric mixtures were used to evaluate the sensor’s performance, demonstrating its capability to detect gases such as CO₂, O₂, and N₂. The results support the applicability of the HCF‐based Raman sensor in future planetary exploration
