Heart testing: Improving the troponin I assay

Date: May 1, 2018

Author: Steve Down

A novel mass spectrometric assay for cardiac troponin I improves upon current immunoassays which give variable results from type to type and facilitates use of troponin in clinical care.

Brain structure changes: Restless legs MRI

Date: May 1, 2018

Author: David Bradley

Magnetic resonance imaging (MRI) has revealed that there are morphological differences in the structure of the somatosensory cortex and the thickness of the corpus callosum subdivisions that provide interhemispheric connections between the two somatosensory cortical areas of the brain in people who suffer with restless legs syndrome.

Fossilized algae: Assisting Raman food testing

Date: May 1, 2018

Author: David Bradley

Photonic crystals derived from fossilised diatoms could be used to boost surface enhanced Raman spectroscopy (SERS) for food safety testing, according to scientists in China and the USA.

Earthly delights: Ultraviolet quantum dots

Date: May 1, 2018

Author: David Bradley

Can scientists use earthworms to make quantum dots? That is a question answered in the positive by researchers from Iran who have used ultraviolet-visible spectroscopy and photoluminescence analysis to confirm the unique absorption and luminescence properties of their products.

Counting tree rings: NMR helps in climate calculations

Date: May 1, 2018

Author: David Bradley

Using a decade-long sequence of annual growth rings from pine trees, scientists have then incorporated data from nuclear magnetic resonance (NMR) spectroscopy into a study to help them correlate carbon metabolism with climate change.

Pillars of Creation: Clues to life

Date: May 1, 2018

Author: David Bradley

Scientists have mimicked the extreme conditions of deep space - cryogenic temperatures, ultrahigh vacuum, lots of ice particles covered with methane, ammonia, and carbon dioxide - and then blasted this miniature universe with low energy electrons, which are abundant in space, to see if they can generate the molecules of life, the amino acids. They used various techniques to pluck out information about of the products and suggest that Fourier transform infrared (FTIR) spectroscopy might be used to obtain...

Journal Highlight: Hydrocerussite‐related minerals and materials: structural principles, chemical variations and infrared spectroscopy

Date: Apr 30, 2018

Author: spectroscopyNOW

The general structural principles, chemical variations and IR spectra of the rapidly growing family of hydrocerussite‐related minerals and synthetic materials have been reviewed and the crystal structures of hydrocerussite from Merehead quarry, Somerset, England, and of its synthetic analogue, have been reported here for the first time.

Journal Highlight: NMReDATA, a standard to report the NMR assignment and parameters of organic compounds

Date: Apr 30, 2018

Author: spectroscopyNOW

A new format called NMReDATA (for nuclear magnetic resonance extracted data) has been proposed for associating the NMR parameters extracted from 1D and 2D spectra of organic compounds to the proposed chemical structures.

Journal Highlight: Trace elements in ancient gold products with PGE microinclusions from archaeological sites of the Urals and North Black Sea Region: LA–ICP–MS data

Date: Apr 30, 2018

Author: spectroscopyNOW

An LA–ICP–MS study of the trace element compositions of archaeological gold products of the Urals and North Black Sea region that contain microinclusions of platinum group minerals indicated that cupellation was the most common technique of gold refinement.
