Journal Highlight: High-resolution MRI of early-stage mouse embryos

Date: Mar 24, 2013

Author: spectroscopyNOW

A method of imaging the mouse embryo from the early stages close to the onset of organogenesis uses a self-gated MRI protocol combined with image registration to obtain whole-embryo high-resolution 3D images.

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.

Carbon capture: Porous trap for greenhouse gas

Date: Mar 15, 2013

Author: David Bradley

Scientists at the King Abdullah University of Science and Technology (KAUST) and the University of South Florida (USF), USA, have developed a unique, efficient, cost-effective as well reusable metal-organic framework (MOF) material, for trapping and separating carbon dioxide from various gas streams. These crystalline materials could lead to clean-air and energy-saving technologies.

Meat test: Llama burger, anyone?

Date: Mar 15, 2013

Author: David Bradley

Partial least-squares regression of data from visible and near infrared reflectance spectroscopy (VIS-NIRS) can be used to quickly discriminate between beef, horse and llama meat in processed food products.

Heavy metal veggies: ICP-MS worth a nickel

Date: Mar 15, 2013

Author: David Bradley

The presence of heavy metal ions of nickel and chromium in vegetables, including potatoes, carrots and onions, irrigated with polluted water is revealed using X-series inductively coupled plasma mass spectrometry.

Journal Highlight: Investigations of chemical warfare agents and toxic industrial compounds with proton-transfer-reaction mass spectrometry for a real-time threat monitoring scenario

Date: Mar 11, 2013

Author: spectroscopyNOW

Chemical warfare agents and toxic industrial compounds have been studied by high-resolution PTR-TOFMS to identify key product ions and their intensities with which to develop a low-resolution PTR-MS system for detecting threat agents in the atmosphere.

Journal Highlight: Donor-substituted distyrylpyrazines: influence of steric congestion on UV–Vis absorption and fluorescence

Date: Mar 11, 2013

Author: spectroscopyNOW

The effects of large substituents on the amino groups in novel synthetic linear 2,5-distyrylpyrazines on steric congestion have been studied by UV–Vis absorption and fluorescence spectroscopy.
