The aerosol end-of-the-pier show
Date: Jul 1, 2009
Author: David Bradley
Understanding future climate change hinges on the analysis of all contributing factors, not least atmospheric aerosols. Now, infrared spectroscopy and mass spectrometry have revealed important clues as to the role of aerosols in affecting climate patterns.

X-shooter takes celestial snapshots
Date: Jun 1, 2009
Author: David Bradley
The European Southern Observatory's Very Large Telescope now has an X-shooter, a second-generation spectroscopic instrument that can record the entire spectrum of a celestial object in a single shot - from the ultraviolet to the near-infrared - with high sensitivity.

In vivo simultaneous measurement of urea and water in the human stratum corneum by diffuse-reflectance near-IR spectroscopy
Date: May 4, 2009
Author:
Urea and water contents in the human stratum corneum were measured coincidentally in vivo after the treatment of urea-containing cream by a Fourier transform near-infrared spectrometer with a fiber-optic probe.

A raspberry flavoured galactic centre with a hint of rum
Date: May 1, 2009
Author: David Bradley
An international team of astronomers has detected two of the most complex molecules yet discovered in interstellar dust: n-propyl cyanide and ethyl formate. The latter gives raspberries their distinct flavour and has a faint rum-like scent.

Infrared monitoring of interlayer water in stacks of purple membranes
Date: Apr 6, 2009
Author:
The thermodynamic behavior of films of hydrated purple membranes from Halobacterium salinarum and the water confined in it was studied by Fourier transform infrared spectroscopy in the 180-280 K range

Going cellular
Date: Apr 1, 2009
Author: David Bradley
An artificial cell made from molybdenum-based building blocks whose pores can open and close has been devised by an international team. The pores can allow molecules that are "too big" into the capsule.

Capabilities of near-IR spectroscopy to analyse changes in water bonding during honey crystallisation process
Date: Mar 2, 2009
Author:
The changes occurring in honey during crystallisation were measured by near-infrared spectroscopy by subtracting the spectrum of the crystallised sample from that of the liquid sample.

Probing the brain wirelessly
Date: Mar 1, 2009
Author: David Bradley
IR-absorbing lead selenide particles form the basis of a method for the study of neuronal activation in samples of brain tissues without the need for hard-wired electrodes. The technique instead utilises light-triggered nanostructured semiconductor photoelectrodes to probe activity.

Microimaging FTIR of head and neck tumors. IV
Date: Feb 2, 2009
Author:
In continuing studies on head and neck neoplasia, specimens from salivary gland tumors have been explored by using infrared microimaging spectroscopy to discern healthy from neoplastic tissues.
