Glowing grains: NIR ID for parathyroid glands

Date: Jul 1, 2011

Author: David Bradley

Researchers have discovered that the parathyroid glands - four small organs each the size of a grain of rice located at the back of the throat - glow with a natural fluorescence in the near infrared. The finding has led to the development of an optical detector for highlighting the glands during endocrine surgery to avoid damage to these essential organs.

Journal Highlight: The application of visible/near-infrared reflectance (VNIR) spectroscopy to chert: A case study from the Dover Quarry sites, Tennessee

Date: Jun 6, 2011

Author:

The application of visible/near-infrared reflectance spectroscopy to chert sourcing attains a cost-efficient, fast, non-destructive, and accurate means of identifying material type and geologic/geographic origin, exemplified by a case study from the Dover Quarry sites, Tennessee.

Slipped disc gel: microbial remedy

Date: Jun 1, 2011

Author: David Bradley

Viable nucleus pulposus (NP) implant materials for repairing damaged intervertebral discs, comprising novel hydrogels, have been developed and studied using the techniques of Fourier-tranform infrared and nuclear magnetic resonance spectroscopy.

Journal Highlight: Infrared spectroscopy and integrated molar absorptivity of C60 and C70 fullerenes at extreme temperatures

Date: May 2, 2011

Author:

The temperature dependences of the wavelength shift and integrated molar absorptivity of the infrared bands of the C60 and C70 fullerenes were determined and extrapolated to derive the values at absolute zero temperature.

FOG overflow: IR clues to drainage problems

Date: May 1, 2011

Author: David Bradley

It is perhaps no real surprise to any chemist who has unblocked a drain clogged with white lardy deposits, but new FTIR spectroscopic evidence confirms that degraded fat, oil and grease (FOG) reacts with calcium compounds in the murky water of drains to form hardened deposits that are, to all intents and purposes, composed of soap, leading to blockages and overflows.

Journal Highlight: Discrimination of seasonality in cheeses by near-infrared technology

Date: Apr 4, 2011

Author:

Rapid prediction of the fat content of cheeses and the seasonal origin (winter or summer) of milk was achieved using near-infrared spectroscopy without previous destruction or treatment of samples.

Sperm condensation: FTIR used to investigate protamines

Date: Apr 1, 2011

Author: David Bradley

Protamines are small basic proteins that condense the genetic material, the DNA, in mature sperm. They are richin the amino acid arginine whose residues are distributed in a number of stretches separated by neutral amino acids. Researchers have used Fourier transform infrared spectroscopy to investigate, for the first time, the secondary structure of protamines in sperm nuclei.

Journal Highlight: Investigation of poly(vinyl chloride)/polystyrene mixture miscibility: Comparison of viscometry criteria with FTIR and refractive index measurements

Date: Mar 7, 2011

Author:

The refractive index and FTIR spectrum of a poly(vinyl chloride)/polystyrene mixture were measured and compared with published results obtained by the viscosity method.

Organic atmospheric: FTIR assesses pollution

Date: Mar 1, 2011

Author: David Bradley

Fourier transform infrared spectroscopy has been used to analyse submicron particles from 14 regions in North America, Asia, South America, and Europe. The measurements were used to identify characteristic organic functional group compositions of fuel combustion, terrestrial vegetation, and ocean bubble bursting sources. The information helps account for more than a third of organic mass in the atmosphere.

Breath test: infrared approach detects exhaled chemicals

Date: Feb 1, 2011

Author: David Bradley

Trace analytes can be detected in the breath using near infrared Fourier transform broadband cavity enhanced absorption spectroscopy. This opens up a whole new area of medical diagnostics and health research.
