NIR CdSeTe
Date: Oct 1, 2009
Author: David Bradley
A near-infrared-emitting alloy of cadmium, selenium, and tellurium, has been used to make a novel type of quantum dot that is of high-quality, water-soluble, and biocompatible. The quantum dots might have application in the analysis and study of biological systems.

Complex biopolymeric systems at stalk/epicuticular wax plant interfaces: A near IR spectroscopy study of sugarcane
Date: Aug 3, 2009
Author:
Naturally occurring macromolecules present at the epicuticular wax/stalk tissue interface of sugarcane were investigated using near IR spectroscopy alone to study water, cellulose, and wax-cellulose interrelationships, where in the past many different techniques have been required.

Reflecting on Martian heat
Date: Aug 1, 2009
Author: David Bradley
A research team in Spain has used infrared spectroscopy to reveal that taking the temperature of the Red Planet is not quite as straightforward as astronomers would like to think. They have demonstrated that the mineralogical chemistry of the planet's surface can influence the precise temperature readings obtained for Martian soil.

Variable-temperature FTIR studies on thermal stability of hydrogen bonding in nylon 6/mesoporous silica nanocomposite
Date: Jul 3, 2009
Author:
Hydrogen bonding in a nylon 6/mesoporous silica nanocomposite was investigated using variable-temperature FTIR spectroscopy. Comparison with the results for nylon 6 showed that mesoporous silica increases considerably the thermal stability of hydrogen bonding.

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.
