Journal Highlight: Verdigris pigment: a mixture of compounds. Input from Raman spectroscopy
Date: Nov 29, 2010
Author:
The reproduction of an old recipe to obtain the pigment known as verdigris leads to a complex mixture of hydrated copper(II) acetates, which was characterised by Raman spectroscopy, Fourier transform infrared spectroscopy and X-ray diffraction.

Ionic liquids in the gas phase - Raman spectroscopy reveals molecular secret
Date: Oct 1, 2010
Author: David Bradley
At first glance ionic liquids would not seem that unusual, heat sodium chloride to a high enough temperature and it will melt. But, ionic materials that are liquid at room temperature are much stranger. Now, a gas-phase Raman study has been used to understand their nature and reveals that in the gas phase each ion of the pair exists as a distinct molecule.

Raman microspectroscopy reveals long-term extracellular activity of Chlamydiae
Date: Aug 2, 2010
Author:
Confocal Raman microspectroscopy was applied to differentiate between reticulate bodies and elementary bodies of Protochlamydia amoebophila and to demonstrate in situ the labelling of this amoeba symbiont after addition of isotope-labelled phenylalanine.

Smooth SERS support
Date: Aug 1, 2010
Author: David Bradley
The judicious use of SERS-active nanoparticles directly or indirectly can surmount the inherent obstacle in the way of the more widespread adoption of surface-enhanced Raman scattering (SERS) studies. Proof of principle in the current work involves activating an organic monolayer by attaching silver nanoparticles.
