- Tracking photo-degradation of triarylmethane dyes with surface-enhanced Raman spectroscopy
Anna Cesaratto, John R. Lombardi and Marco Leona
Version of Record online: 25 OCT 2016 | DOI: 10.1002/jrs.5056
This work aims to study the photo-degradation products of triarylmethane dyes by Surface-Enhanced Raman Spectroscopy (SERS). After comparing the SERS spectra of basic fuchsine, methyl violet, and crystal violet, the feasibility of SERS to evaluate the N-demethylation degradation process of crystal violet have been verified. The results have been used to interpret the data obtained from Meiji Japanese woodblock prints.
- Ex vivo detection and characterization of remineralized carious dentin, by nanoindentation and single point Raman spectroscopy, after amalgam restoration

Zn-containing amalgam produced remineralization of the caries-affected dentin surfaces. An increase in nanomechanical properties, maturation of minerals, lower degrees of impurities, or crystal imperfections and crystallographic disorders were detected. These parameters indicated new crystalline mineral formation, at the restored interfaces. An increase of mineralization, associated to broaden of the phosphate peaks in the v1 spectra region, without influencing the mechanical properties was also determined. It corroborated the augmentation of amorphous content at the remineralized dentin surface.
- Raman imaging processed cheese and its components

Version of Record online: 21 OCT 2016 | DOI: 10.1002/jrs.5054
Many of the components in processed cheese produce distinct Raman spectra. By taking advantage of this, Raman microscopy can be used to effectively image the microstructure of processed cheese without the need for potentially intrusive dyes. This investigation monitored the distribution of several components which are often present in processed cheeses including: fat, protein, water, trisodium citrate, paprika and starch.
- Micro-Raman and SER spectroscopy to unfold Lefranc's early organic pigment formulations
F. Gabrieli, B. Doherty, C. Miliani, I. Degano, F. Modugno, D. Uldank, D. Kunzelman, E. Buzzegoli, M. Patti and F. Rosi
Version of Record online: 17 OCT 2016 | DOI: 10.1002/jrs.5052
In this work, combined Raman and chromatography techniques have been utilized to probe organic pigment constituents of 16 in-house Lefranc experimental formulations. Highlighted use of natural neoflavonoids, anthraquinones, and synthetic azo pigments and mixtures provides a greater understanding of early laboratory syntheses for heritage science purposes.
- Kinetics of enzyme-catalysed oxygen isotope exchange between phosphate and water revealed by Raman spectroscopy
Christian von Sperber, Hans Lewandowski, Federica Tamburini, Stefano M. Bernasconi, Wulf Amelung and Emmanuel Frossard
Version of Record online: 17 OCT 2016 | DOI: 10.1002/jrs.5053
Here, we show that Raman spectroscopy can be applied to monitor enzyme-catalysed oxygen isotope exchange between phosphate and water. Quantification of the overlapping Raman spectra allowed to calculate the overall reaction rate of the oxygen isotope exchange.
