Journal Highlight: High-spatial-resolution mapping of superhydrophobic cicada wing surface chemistry using IR microspectroscopy and IR imaging at two synchrotron beamlines
Date: May 15, 2013
Author: spectroscopyNOW
The chemical composition of the wings of the Clanger cicada (Psaltoda claripennis) were characterized using infrared (IR) microspectroscopy and IR imaging with a view to reproducing their characteristics in industrial applications.

Combined forces: AFM boosts IR
Date: May 1, 2013
Author: David Bradley
A technique that combines atomic force microscopy (AFM) with infrared spectroscopy has allowed researchers, for the first time, to study the infrared absorption of semiconductor plasmonic microparticles on the nanometre scale.

Journal Highlight: Assessment of resin formulations and determination of the formaldehyde to urea molar ratio by near- and mid-infrared spectroscopy and multivariate data analysis
Date: Apr 15, 2013
Author: spectroscopyNOW
The molar ratios of formaldehyde to urea in resin formulations have been analyzed by ATR-FTIR and FT-NIR spectroscopy, using PCA to separate them according to molar ratios and to distinguish between two groups of resins, and SIMCA to classify new resin samples.

Journal Highlight: Analysis of audio magnetic tapes with sticky shed syndrome by ATR-FTIR
Date: Apr 1, 2013
Author: spectroscopyNOW
ATR-FTIR spectroscopy was used to identify spectroscopic markers for sticky shed syndrome in audio magnetic tapes with a poly(ester urethane) binder layer that are held in Library of Congress collections.

Venusian vortex: Infrared images of planetary sibling
Date: Apr 1, 2013
Author: David Bradley
The South Polar Vortex of the planet Venus, second planet from the Sun, shows a much more chaotic and unpredictable weather system than had previously been recognised by astronomers. A new analysis of IR images shows that the axis of rotation of this vortex is nomadic about the pole depending on the particular altitude level in the clouds at which it is observed, revealing a much more unpredictable storm and morphology than thought.

Journal Highlight: Detection of low-quality extra virgin olive oils by fatty acid alkyl esters evaluation: a preliminary and fast mid-IR spectroscopy discrimination by a chemometric approach
Date: Mar 18, 2013
Author: spectroscopyNOW
FT mid-IR spectroscopy with partial least squares analysis was used to predict the contents of fatty acid methyl and ethyl esters in extra virgin olive oils, allowing low-quality products to be identified.

Journal Highlight: Infrared imaging as a cancer diagnostic tool: Introducing a new concept of spectral barcodes for identifying molecular changes in colon tumors
Date: Mar 4, 2013
Author: spectroscopyNOW
A biophotonic approach based on IR spectral micro-imaging combined with multivariate statistical analysis has been implemented on colon tissues to develop a new concept of spectral bar coding.

Water, water everywhere: Even on the Moon
Date: Mar 1, 2013
Author: David Bradley
An analysis of tiny mineral deposits from lunar anorthosites brought back to Earth by Apollo astronauts adds new evidence to suggestions that water was not lost to space during the formation of the Moon. The analysis was carried out using Fourier-transform infrared (FTIR) spectroscopy.

Journal Highlight: Could infrared spectroscopy identify melamine-related stone using melamine-contained mixture as a reference?
Date: Feb 4, 2013
Author: spectroscopyNOW
The infrared spectra of dry melamine-containing mixtures are different from those of melamine-containing stones formed in urine, so cannot be used for reference purposes.

An eye for the dye: Novel IR sensors
Date: Feb 1, 2013
Author: David Bradley
Image sensors developed by researchers at the Technische Universität München (TUM) are more sensitive to light than the conventional silicon devices. The sensors are simple and inexpensive to produce and could easily be modified by switching dye molecules to use them for infrared applications.
