- Rapid 3D chemical-specific imaging of minerals using stimulated Raman scattering microscopy
Marie-Andrée Houle, Robert C. Burruss, Andrew Ridsdale, Douglas J. Moffatt, François Légaré and Albert Stolow

We present the first applications of stimulated Raman scattering microscopy, a nonlinear optical Raman technique, to samples of mineralogical interest. Combined with second harmonic generation microscopy, stimulated Raman scattering offers a multimodal tool for rapidly imaging mineral samples having chemical specificity, structural sensitivity, and excellent three-dimensional resolution. In mineralogical applications, our wide-tuning range offers hyperspectral imaging of both trapped organics, via the CH region (~2900 cm−1), and the low-frequency (<1000 cm−1) modes important for mineral identification.
- Thermodynamic CoO–Co3O4 crossover using Raman spectroscopy in magnetic octahedron-shaped nanocrystals
Beatriz Rivas-Murias and Verónica Salgueiriño
Version of Record online: 8 MAR 2017 | DOI: 10.1002/jrs.5129
The thermodynamic crossover of octahedron-shaped nanocrystals of cobalt(II) oxide to oxidized Co3O4 normal spinel is studied using Raman spectroscopy. For that, the effect of the laser power from 0.3 (0.05%) to 69 (100%) mW and of the exposure time using different laser wavelengths was analyzed. Controlling both laser power and time exposure, the sample evolution from CoO rock salt to Co3O4 fcc spinel was attained, stemming from the energy transfer and consequent local heating.
- The effect of excitation wavelength and metallic nanostructure on SERS spectra of C60
Miri Sinwani, Merav Muallem and Yaakov R. Tischler
Version of Record online: 8 MAR 2017 | DOI: 10.1002/jrs.5126
In this study, we investigated the surface-enhanced Raman scattering spectra of Fullerene C60 evaporated on tapered Au thin films that contain several nanomorphologies with two excitation wavelengths: 532 and 784 nm. We show that each excitation wavelength reveals the strongest surface-enhanced Raman scattering signal at different regions in the tapered Au film. We explain these observations as a result of different Raman enhancement mechanisms.
- Raman spectral variation for human fingernails of postmenopausal women is dependent on fracture risk and osteoporosis status
J. R. Beattie, M. C. Caraher, N. M. Cummins, O. M. O'Driscoll, R. Eastell, S. H. Ralston and M. R. Towler

Human nail protein structure and composition are affected by systemic factors that are associated with poor bone health. Fracture risk is associated with restructuring of nail keratin and compositional changes. Osteoporosis is associated with changes in the ionization of acid residues in the nail keratin.

Comparison between a natural sample of forsterite (Fo#89) unpolarized Raman spectrum (bottom) and a calculated forsterite Mg2SiO4 by means of CRYSTAL14 (top). The box at the top on the left is an enlargement of wavenumbers from 150 to 500 cm−1 to emphasize peaks at low wavenumbers.
