Near infrared spectroscopy of nanostructured materials

As nanotechnology grows in importance, the need for rapid, easy and automated analytical methods to investigate new nanomaterials increases. Near infrared (NIR) spectroscopy has the potential to replace numerous methods for the investigation of a wide range of nanostructured materials and with particular potential in the area of PAT.

Liquid-phase analytical applications of UV-visible broadband cavity-enhanced absorption spectroscopy (BBCEAS)

BBCEAS is a new cavity-based absorption technique that uses broadband sources rather than lasers. This offers potential improvements in signal-to-noise but often lower spectral resolution compared to techniques where the laser wavelength is scanned. The article concentrates on liquid-phase applications, an interesting new area since most cavity-based absorption studies have been performed on gas-phase species up to now.

The use of complementary techniques in understanding the detoxification of aluminium in the freshwater snail, Lymnaea stagnalis

The authors describe the use of a range of complementary methods to explore cellular, physiological and behavioural mechanisms underlying Al accumulation and toxicity, and its eventual fate, using the pond snail as a model organism.

The search for signatures of early life on Mars: Raman spectroscopy and the Exomars mission

User Rating: / 1
PoorBest 

raman-23_1-F1-sRaman spectroscopy is to be used as one of the analytical techniques for the European Space Agency’s ExoMars mission to identify the geological and biogeological spectral signatures that could herald the presence of extinct or extant life on Mars. The article looks at the benefits of Raman spectroscopy for this and the research on Earth to build knowledge of the spectra of organisms living in extreme conditions here.
