Golden probe: Opening the cluster

Date: Apr 15, 2019

Author: David Bradley

Phosphorus-31 nuclear magnetic resonance (NMR) spectroscopy was the "perfect probe" in a study of a ligand-protected golden fullerene, according to research published in Angewandte Chemie.

Journal Highlight: Explosive emulsion characterisation using nuclear magnetic resonance

Date: Apr 3, 2019

Author: spectroscopyNOW

The droplet size distribution of explosive emulsions, which is critical to assessing long‐term stability and explosive effectiveness, has been determined by NMR pulsed field gradient techniques.

Programmed cell death: Solid-state NMR insights

Date: Apr 1, 2019

Author: David Bradley

Researchers from The Netherlands and the USA have used solid-state nuclear magnetic resonance (NMR) spectroscopy to show how the signal induced by the enzyme cytochrome C is more controlled than was originally anticipated. The discovery could have implications for understanding mitochondria and programmed cell death.

Journal Highlight: Reducing the computational cost of NMR crystallography of organic powders at natural isotopic abundance with the help of 13C‐13C dipolar couplings

Date: Mar 7, 2019

Author: spectroscopyNOW

13C‐13C Dipolar couplings quantified on powdered theophylline at natural isotopic abundance have been used with the help of dynamic nuclear polarisation to carry out DFT‐free, rapid screening of a pool of structures predicted by AIRSS.

Urea complexes: NMR examination and more

Date: Mar 1, 2019

Author: David Bradley

A whole raft of techniques including nuclear magnetic resonance (NMR) spectroscopy have been used to analyse and characterise two synthesised complexes of zinc and nickel with the urea derivative, 2-benzimidazolyl-urea (BZIMU). The compounds show promised against cancer cell lines in the laboratory as well as antibacterial activity.

Staph fights copper: NMR and resistance

Date: Feb 15, 2019

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy has been used to reveal the three-dimensional structure of the copL protein in the Bacillus subtilis bacterium, a close relative of Staphylococcus aureus. The approach reveals copper ions can bind to the surface of the protein and points to how resistance to this antibacterial agent can arise.

Journal Highlight: NMR as a new tool for cultural heritage application: The provenance of ancient white marbles

Date: Feb 8, 2019

Author: spectroscopyNOW

NMR spectroscopy has been applied for the first time to the study of ancient marbles by tracking the 13C nuclide of calcite to highlight the crystal defects and the presence of trace elements, thus providing a signature for the provenance of marble.

Enhanced NMR: Proteins yield

Date: Feb 1, 2019

Author: David Bradley

A team from Massachusetts Institute of Technology (MIT) has found that they can enhance nuclear magnetic resonance (NMR) spectroscopy in such a way as to facilitate the structure determination of proteins associated with a wide range of diseases.

Urban mining: NMR helps find the golden key

Date: Jan 15, 2019

Author: David Bradley

An international team has used nuclear magnetic resonance (NMR) spectroscopy and high-resolution mass spectrometry (HRMS) in a study that has led to the proposal of a selective, fast, and convenient thiol-assisted gold leaching process for the urban mining of this precious metals from the electronic equipment waste stream.
