Space balls

Date: Aug 1, 2010

Author: David Bradley

Infrared spectroscopic data from the planetary nebula Tc 1 in the southern constellation Ara has now revealed convincing evidence that the fullerenes, C60 and C70, are present in large quantities in cosmic dust.

Determination of water penetration and drug concentration profiles in HPMC-based matrix tablets by near infrared chemical imaging

Date: Jul 5, 2010

Author:

Near infrared chemical imaging and chemometric data analysis were used to study hydration behaviors of prolonged release tablets, which contain a high solubility drug at high load and a hydrophilic polymer hydroxypropylmethylcellulose (HPMC).

Life's molecules in outer space

Date: Jul 1, 2010

Author: David Bradley

An astronomical infrared study reveals one of the most complex organic molecules yet found in the interstellar medium - anthracene - offering possible new clues to the way the building blocks of life might have emerged.

An FTIR study of the induction and release of kiwifruit buds from dormancy

Date: Jun 7, 2010

Author:

FTIR spectrometry was used to provide an alternative mechanism for tracking metabolic changes in the meristems of kiwifruit buds during winter dormancy.

Nano rice

Date: Jun 1, 2010

Author: David Bradley

Heating rice flour to 600 Celsius under a nitrogen atmosphere is not the usual way to cook it, but researchers in India have done just that. The product, rather than a bowl of light and fluffy grains is a plethora of nanoscopic carbon cubes and bricks, the team says

All about crystal Eve

Date: May 1, 2010

Author: David Bradley

Scientists have reported the discovery of what may be the "ancestral Eve" crystal that billions of years ago gave life on Earth its curious and exclusive preference for so-called left-handed amino acids. Fourier transform IR spectroscopy and powder X-ray diffraction provide the evidence.

Marvellous time for monitoring moonshine

Date: Apr 1, 2010

Author: David Bradley

A portable IR device that can quickly and easily determine the strength of alcoholic drinks proves more effective than laboratory-based FTIR spectroscopy. The device could be useful in law enforcement and in industry fraud.

Structure characterization of films from drying oils cured under infrared light

Date: Apr 1, 2010

Author:

Infrared radiation was used to increase the curing rate of linseed and tung oils and FTIR spectroscopy was used to monitor the chemical changes during oil oxidation.

NIR focus on energy molecule

Date: Mar 1, 2010

Author: David Bradley

Organisms use ATP as a universal energy storage molecule, now carbon nanotubes, modified with luciferase, have been used as near-infrared detectors for cellular ATP. The work has potential for studies of ischaemia, Parkinson's disease, hypoglycaemia and more.
