Journal Highlight: Near-infrared fluorescence imaging of lymphatics in head and neck lymphedema
Date: Apr 2, 2012
Author: spectroscopyNOW
Near-infrared fluorescence imaging was used to understand the lymphatic anatomy and function and help direct manual lymphatic drainage in a patient with head and neck lymphedema after surgery and radiation treatment, using 3D surface profilometry to monitor response to therapy.

Journal Highlight: Evaluation of the quality of deep frying oils with Fourier Transform near-infrared and mid-infrared spectroscopy
Date: Mar 5, 2012
Author:
The quality of deep frying oils collected from a local college canteen was examined by Fourier transform mid-infrared and Fourier transform near-infrared spectroscopy using partial least squares regression to correlate spectral data with free fatty acid and peroxide values of frying oils.

Journal Highlight: Quantitative determination of degree of conversion in photocured poly(urethane-dimethacrylate)s by FTIR spectroscopy
Date: Feb 6, 2012
Author:
FTIR spectroscopy was used to characterize the degree of double bond conversion in six series of poly(urethane-dimethacrylate)s, derived from dicarbamates of oligoethylene glycols monomethacrylates and aliphatic, cycloaliphatic and aromatic diisocyanates.

Infrared universe: Hubble spies dark energy clue
Date: Feb 1, 2012
Author: David Bradley
NASA's Hubble Space Telescope has looked deep into near-infrared of the distant universe to detect the feeble afterglow of a star that exploded more than 9 billion years ago. The research offers the first glimpse of constraints to help us explain dark energy.

Journal Highlight: Using FTIR to predict saccharification from enzymatic hydrolysis of alkali-pretreated biomasses
Date: Jan 9, 2012
Author:
Fourier transform infrared, attenuated total reflectance spectroscopy combined with partial least squares regression accurately predicted 72-h glucose and xylose conversions and yields from cellulase-mediated hydrolysis of alkali-pretreated lignocellulose.

Titanic weather: Methane recycled
Date: Jan 5, 2012
Author: David Bradley
Titan, the planet Saturn's largest and perhaps its most intriguing moon, has weather patterns that are akin to those found on earth but rather than being underpinned by a water cycle, it is methane that circulates across the orb. A new study published in Nature corroborates infrared mapping to reveal methane lakes in the moon's polar regions, "dry" low latitudes with fluvial features, and occasional rainstorms, as well as tropospheric clouds found so far mainly in mid-southern latitudes and the polar...

Journal Highlight: Complementary near-infrared and Raman chemical imaging of pharmaceutical thin films
Date: Dec 5, 2011
Author:
Complementary near-infrared and Raman mapping techniques have been used to study the distribution of drug particles suspended in polymeric films designed to enhance dissolution rates of poorly soluble drugs and to aid the content uniformity of drugs administered in low doses.

Water world: IR astronomy reveals cloudy system
Date: Nov 1, 2011
Author: David Bradley
Astronomers have used far-infrared instrumentation to show for the first time a cloud of water vapour swirling around a burgeoning solar system. The vapour is cold enough to form comets, which could eventually deliver oceans to the distant system's parched newly forming planets.
