Journal of Raman Spectroscopy: Special Issue on Art and Archaeology
Date: Dec 3, 2012
Author: spectroscopyNOW
Don't miss these key papers from the International Congress on the Application of Raman Spectroscopy in art and archaeology. RAA 2011 focused on the analysis by means of Raman spectroscopy of materials related to cultural heritage and archaeology - pigments, dyes, inks, paper, polymers, glass, ceramics, resins, fibers, corrosion products, including topics related to natural heritage - gemstones, minerals, fossils, and some aspects involving forensic science. The Editorial and several papers are free to...

A chip the size of a fingernail uses surface-enhanced Raman spectroscopy (SERS) to sniff out explosives and avoids the problem of bad dog days in airports and other security-sensitive environments. The system has the potential to be developed into a compact device resembling a smoke alarm to alert the authorities to a potentially explosive problem.

Author: David Bradley
Non-pathogenic microbes found in samples of Chinese dried pork could be used to form nitrosylmyoglobin in preserved meats without the addition of the nitrite preservatives commonly used in bacon products and other meats that have come under fire because of concerns about carcinogenicity. Raman spectroscopy and other techniques were used to demonstrate the formation of the nitrosylmyoglobin and provides critical data on potential safety and viability.

Date: Nov 1, 2012
Author: David Bradley
Fourier transform infrared and Raman microspectroscopy, as well as other techniques have been used to test a putative, non-carcinogenic metal coating material based on molybdate to replace chromate for corrosion protection of aluminium in the automobile, aerospace and engineering industries.
