Date: Jan 7, 2013
Author: David Bradley
A new spectroscopic method has been developed for the determination of the drug furosemide used to treat congestive heart failure and other conditions.
Read MoreJournal Highlight: FTIR spectra of algal species can be used as physiological fingerprints to assess their actual growth potential
Date: Dec 3, 2012
Author: spectroscopyNOW
FTIR spectra were measured from cells of two algal species whose growth rates were manipulated by the availability of nutrients or light and a species-specific model was developed to predict the growth rate.
Read MoreThe heat is on: NIR tumour ablation
Date: Dec 1, 2012
Author: David Bradley
Researchers have discovered that if you expose modified electrically conductive polymers to near-infrared light they can generate localised heat to kill colorectal cancer cells through thermal ablation.

Date: Nov 5, 2012
Author: spectroscopyNOW
In this minireview, the power of CO infrared absorption spectroscopy as a probe for the characterization of novel nanostructured catalysts is discussed.
Read MoreCorrosion coating: Chromate replacement
Date: Nov 1, 2012
Author: David Bradley
Fourier transform infrared and Raman microspectroscopy, as well as other techniques have been used to test a putative, non-carcinogenic metal coating material based on molybdate to replace chromate for corrosion protection of aluminium in the automobile, aerospace and engineering industries.
Read MoreVendor column: If you aren’t controlling your process, your process is controlling you
Date: Oct 29, 2012
Author: Daniel Shiley
This is the fourth and final segment in the series on near-infrared for the mining industry. Development of quantitative data sets was discussed in the previous article. This article will discuss the finished quantitative model as it can be used to optimize mine productivity.
Read MoreJournal Highlight: Structural differences between wood species: Evidence from chemical composition, FTIR spectroscopy, and thermogravimetric analysis
Date: Oct 1, 2012
Author: spectroscopyNOW
The relationship between wood cellulose crystallinity, influence of extractives on wood degradation, correlation between chemical composition, and physical properties of four wood species were investigated by chemical analysis, FTIR spectroscopy, and thermogravimetry
Read MoreSkin scan: NIR cancer mapping
Date: Oct 1, 2012
Author: David Bradley
Non-invasive mapping of the network of tiny blood vessels beneath the skin is now possible thanks to an advanced optics system and near-infrared imaging. The new technique could one day be used to quickly and efficiently reveal the latent signs of skin disorders, such as psoriasis or even skin cancer.
