Martian atmospherics: Peering into the past
Date: Aug 1, 2013
Author: David Bradley
An Imaging Ultraviolet Spectrometer will provide complementary data to the Neutral Gas and Ion Mass Spectrometer (NGIMS) and other instruments aboard NASA's MAVEN spacecraft, which is destined for Mars and will measure the gas composition of the Red Planet to give us a clearer picture of its past.

Lip up: Fatty molecules investigated
Date: Jul 1, 2013
Author: David Bradley
Fatty lipid molecules in the human body act not only as energy storage molecules and structural elements but are also important signalling compounds. Lipids with their head in a molecular cage have now been used to study such molecules and their roles in diseases such as atherosclerosis and diabetes.

Journal Highlight: Spectroscopic studies on nicotine and nornicotine in the UV region
Date: Jun 10, 2013
Author: spectroscopyNOW
The UV absorption and electronic circular dichroism (ECD) spectra of (R)- and (S)-nicotine and (S)-nornicotine in aqueous solution were measured to a significantly lower wavelength range than previously reported, allowing the identification of four previously unobserved electronic transitions.

Colours to dye for: Spray on pigments
Date: Jun 1, 2013
Author: David Bradley
Japanese scientists have developed a new type of colouring agent that is not only environmentally friendly but does not fade like conventional textile dyes and pigments. The colourants consist of submicrometre-sized silicon dioxide particles and carbon black and can be sprayed on to the desired surface to generate bright colours that are permanent and highly fade resistant.

Journal Highlight: Determination of the anti-viral drug Ribavirin in dosage forms via micelle-enhanced spectrofluorimetric method
Date: May 7, 2013
Author: spectroscopyNOW
A simple and sensitive spectrofluorimetric method was developed for the determination of Ribavirin in pharmaceutical formulations, based on its fluorescence spectral behaviour in a sodium dodecyl sulfate micellar system.

Sweet red wine: Ultraviolet exposure
Date: May 1, 2013
Author: David Bradley
UV-Vis spectroscopy has been used for the first time to study phenolics and other compounds present in a type of sweet, red wine emerging from the North West of Spain. The approach could be used to study the components of other beverages too as well as offering quality analysis (QA) data on produce.

Journal Highlight: Visible and near infrared fluorescence spectral flow cytometry
Date: Apr 8, 2013
Author: spectroscopyNOW
Spectral flow cytometry instruments, software and experimental design that allow spectral flow cytometry to be integrated with conventional flow cytometry approaches are described and several near infrared emitting fluorophores are evaluated.

Chlorophyll f: UV sheds some light on infrared molecule
Date: Apr 1, 2013
Author: David Bradley
Chlorophyll f is the most red-shifted natural chlorophyll and is made by the blue-green alga Halomicronema hongdechloris. Researchers have now carried out a structural assignment UV-Vis spectroscopy and other techniques. New insights into chlorophyll and its variants is important for understanding photosynthesis as well as for research into energy conversion, electron transfer applications.
