rssJournal 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...

Journal Highlight: The first in situ micro-Raman spectroscopic analysis of prehistoric cave art of Rouffignac St-Cernin, France
Date: Dec 3, 2012
Author: spectroscopyNOW
The first in situ micro-Raman spectroscopic study of prehistoric drawings found in the cave of Rouffignac-Saint-Cernin (Dordogne, France) was carried out using non-destructive analyses to identify carbon-based drawings.

Journal Highlight: On the embalmment of S. Francesco Caracciolo
Date: Dec 3, 2012
Author: spectroscopyNOW
Four samples of the remains of S. Caracciolo have been analysed for traces of embalmment using cold vapour atomic absorption spectroscopy, which revealed low background levels of As and high levels of Hg.

Journal Highlight: Combined use of filtered and edited 1H NMR spectroscopy to detect 13C-enriched compounds in complex mixtures
Date: Dec 3, 2012
Author: spectroscopyNOW
The 13C background signal can be distinguished from resonances of 13C-enriched xenobiotics by the absence of a 12C component, detected by combined analysis of 13C-filtered and -edited proton NMR spectra.

Journal Highlight: FTIR spectra of algal species can be used as physiological fingerprints to assess their actual growth potential
Date: Dec 3, 2012
Author: spectroscopyNOW
FTIR spectra were measured from cells of two algal species whose growth rates were manipulated by the availability of nutrients or light and a species-specific model was developed to predict the growth rate.

Single cell spectrometry: Inkjet printing and ambient mass spectrometry for lipid profiling
Date: Dec 2, 2012
Author: Steve Down
The phospholipids in single cells that have been printed using a custom inkjet printer were analysed by liquid extraction surface analysis coupled to nanospray mass spectrometry, allowing cell types to be differentiated.

Muse on X-rays: Supermassive black hole
Date: Dec 1, 2012
Author:
A supermassive black hole 12.4 billion light years from Earth is pumping out a jet of X-rays that could give astronomers using NASA's Chandra X-ray Observatory a glimpse into how such bodies form and the role they play in galaxy formation in the early universe.

Cognitive integrity: MRI reveals benefits
Date: Dec 1, 2012
Author:
A study using magnetic resonance imaging (MRI) shows that mental activities like reading and writing can preserve structural integrity in the brains of older people. Details were reported at the annual meeting of the Radiological Society of North America (RSNA).

A sense of Mars: Atmospheric probe
Date: Dec 1, 2012
Author:
A remote sensing instrument that will peer into the ultraviolet to offer clues to how Mars might have lost its atmosphere has arrived at Lockheed Martin for integration into NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft.

Particulate matter: NMR checks on brain cancer
Date: Dec 1, 2012
Author:
NMR relaxometry can be used to detect the minuscule cell particles (microvesicles) that are shed by cancer cells and enter the blood stream. The approach offers the potential for a simple, inexpensive and relatively non-invasive way to diagnose and monitor brain cancer researchers say.
