Catalytic carbenes: UV and the metal connection
Date: Oct 1, 2013
Author: David Bradley
A team of scientists led by University of Wisconsin-Madison chemist John Berry has developed a technique that lets them freeze the action in a reaction catalysed by a dirhodium carbene complex long enough during a critical step so that they can see the fine details of the mechanism using UV spectroscopy and other techniques.

Journal Highlight: Fluorescence lifetime imaging of lignin autofluorescence in normal and compression wood
Date: Sep 9, 2013
Author: spectroscopyNOW
The fluorescence lifetime of wood cell walls was examined using time-correlated single photon counting to detect differences in lignin composition and measure the molecular environment within cell walls of normal and compression wood.

Natural light: Prototyping light harvesters
Date: Sep 1, 2013
Author: David Bradley
A ring of protein and pigments, half synthetic and half natural, can be used to quickly prototype light-harvesting antennae that absorb more sunlight than their wholly natural counterparts. The system could be used to prototype ultraviolet and visible absorbing molecules for solar energy trapping.

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.
