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.

Journal Highlight: Use of near-IR spectroscopy to distinguish carbon and nitrogen originating from char and forest-floor material in soils: usefulness of a genetic algorithm
Date: Oct 3, 2011
Author:
The potential of a genetic algorithm for spectral feature selection and interpretation of near-IR spectra in soil science studies was examined for predicting C and N from char and forest-floor material and compared with a partial least squares method.

Porous boron: Heralding hydrogen economy
Date: Oct 1, 2011
Author: David Bradley
Researchers in Europe have developed a hydrogen storage material based on porous magnesium borohydride that can safely adsorb large quantities of the gas via both a physical and a chemical mechanism. They used X-ray diffraction, infra-red and Raman spectroscopy to investigate this material.

Journal Highlight: Examining the phonological neighborhood density effect using near infrared spectroscopy
Date: Sep 6, 2011
Author:
Neurobehavioral correlates of phonological neighborhood density in skilled readers of English have been explored using near infrared spectroscopy, showing that words with many neighbors elicited significantly greater changes in blood oxygenation in the left than in the right hemisphere of the brain.

Infrared dwarf: Icy world of slushy volcanoes
Date: Sep 1, 2011
Author: David Bradley
US astronomers have used infrared techniques to reveal that the dwarf planet, nicknamed Snow White, is an icy world half covered in water ice that once spewed from slush volcanoes. Their data also hints that the planet has an atmosphere of methane, that is gradually evaporating into space.

Journal Highlight: Measurement of the variation of crystal lattice structures of ethylene copolymers with high-resolution cryogenic FTIR spectroscopy
Date: Aug 2, 2011
Author:
A high-resolution cryogenic FTIR study of the variation of unit cell volume of ethylene-octene copolymers found that both the comonomer content and thermal history have great influence on the crystal lattice structure of ethylene polymers.
