Solar-powered windows: Transparent reaction
Date: Aug 1, 2012
Author: David Bradley
US researchers have developed a polymer that is photoactive in the near-infrared (NIR) rather than the visible region of the electromagnetic spectrum and so might be used as a transparent layer for converting ordinary windows into in situ solar panels.

Journal Highlight: Infrared spectroscopy of hydrogenated fullerenes (fulleranes) at extreme temperatures
Date: Jul 2, 2012
Author: spectroscopyNOW
The infrared spectra, integrated molar absorptivity and molar extinction coefficient of each infrared transition of the three fulleranes and a mixture of fulleranes are presented and discussed.

Fireflies after dark: Flashy nuptial gifts
Date: Jul 1, 2012
Author: David Bradley
Once the lights go out, female fireflies apparently prefer a little more substance and a little less flash. Infrared imaging and other techniques have been used to monitor firefly behaviour and to show that the females of the species tend to choose mates that they perceive as able to deliver a large "nuptial gift" a high protein sperm package that helps females produce more eggs.

Vendor column: Qualitative models and their application to mining – “How you gonna get any gold if you’re not diggin’?”
Date: Jun 13, 2012
Author: Daniel Shiley
This is the second of a four-part series on chemometric applications for materials analysis. Those of you who have watched the “Gold Rush Alaska” television show on the Discovery Channel might recognize the quote. This is an old attitude, much different than today’s commercial mining companies, which are all very concerned with obtaining information before they begin to dig. The data derived from near-infrared (NIR) analysis often plays an important role in development of this much needed data.

Journal Highlight: Infrared spectrum and structure of the adamantane cation: Direct evidence for Jahn-Teller distortion
Date: Jun 4, 2012
Author: spectroscopyNOW
The IR spectrum of the adamantane cation has been derived by resonant IR photodissociation of weakly bound clusters with helium and nitrogen.

Journal Highlight: Comparability of protein therapeutics: Quantitative comparison of second-derivative amide I infrared spectra
Date: May 15, 2012
Author: spectroscopyNOW
Four common algorithms, including those employing spectral correlation coefficient and area of overlap, are compared for their ability to determine the secondary structure of proteins from their amide I regions as a function of changes in pH or temperature.
