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.

Journal Highlight: Structural determinants of ligand binding in truncated hemoglobins: Resonance Raman spectroscopy of the native states and their carbon monoxide and hydroxide complexes

Date: Apr 30, 2018

Author: spectroscopyNOW

The use of resonance Raman spectroscopy to study ligand binding in truncated hemoglobins has been reviewed, focussing on three hemoglobins from Thermobifida fusca and Pseudoalteromonas haloplanktis.

Journal Highlight: Changes in the proteome of the problem weed blackgrass correlating with multiple herbicide resistance

Date: Apr 23, 2018

Author: spectroscopyNOW

The evolution of multiple herbicide resistance in populations of the weed blackgrass (Alopecurus myosuroides) has been investigated using a combination of transcriptomics and proteomics.

Journal Highlight: In vivo hyperpolarization transfer in a clinical MRI scanner

Date: Apr 23, 2018

Author: spectroscopyNOW

The purpose of this study was to investigate the feasibility of in vivo 13C→1H hyperpolarization transfer, which has significant potential advantages for detecting the distribution and metabolism of hyperpolarized 13C probes in a clinical MRI scanner.

Journal Highlight: Big (bio)chemical data mining using chemometric methods: A need for chemists

Date: Apr 16, 2018

Author: spectroscopyNOW

The capabilities and versatility of chemometric methods have been discussed in light of the big (bio)chemical data challenges that are being encountered in chromatographic, spectroscopic and hyperspectral imaging measurements, with an emphasis on their application to omics sciences.
