Journal Highlight: Comparability of protein therapeutics: Quantitative comparison of second-derivative amide I infrared spectra

Date: May 15, 2012

Author: spectroscopyNOW

Four common algorithms, including those employing spectral correlation coefficient and area of overlap, are compared for their ability to determine the secondary structure of proteins from their amide I regions as a function of changes in pH or temperature.

Journal Highlight: Evaluation of the quality of deep frying oils with Fourier Transform near-infrared and mid-infrared spectroscopy

Date: Mar 5, 2012

Author:

The quality of deep frying oils collected from a local college canteen was examined by Fourier transform mid-infrared and Fourier transform near-infrared spectroscopy using partial least squares regression to correlate spectral data with free fatty acid and peroxide values of frying oils.

Journal Highlight: Quantitative determination of degree of conversion in photocured poly(urethane-dimethacrylate)s by FTIR spectroscopy

Date: Feb 6, 2012

Author:

FTIR spectroscopy was used to characterize the degree of double bond conversion in six series of poly(urethane-dimethacrylate)s, derived from dicarbamates of oligoethylene glycols monomethacrylates and aliphatic, cycloaliphatic and aromatic diisocyanates.

Infrared universe: Hubble spies dark energy clue

Date: Feb 1, 2012

Author: David Bradley

NASA's Hubble Space Telescope has looked deep into near-infrared of the distant universe to detect the feeble afterglow of a star that exploded more than 9 billion years ago. The research offers the first glimpse of constraints to help us explain dark energy.

Journal Highlight: Using FTIR to predict saccharification from enzymatic hydrolysis of alkali-pretreated biomasses

Date: Jan 9, 2012

Author:

Fourier transform infrared, attenuated total reflectance spectroscopy combined with partial least squares regression accurately predicted 72-h glucose and xylose conversions and yields from cellulase-mediated hydrolysis of alkali-pretreated lignocellulose.
