Solid-state NMR joins IUCr

Date: Nov 20, 2014

Author: Professor Robin Harris, University of Durham

In this International Year of Crystallography, NMR has at last established its own Commission within The International Union of Crystallography, joining 22 other commissions on a whole range of crystallographic subjects.

Insecticidal fungi: Enzyme inhibitors extracted

Date: Nov 15, 2014

Author: David Bradley

Screening of dozens of strains of fungi that infect insects has led to the discovery of a strong inhibitor for the enzyme tyrosinase. Tyrosinase activity is involved in insect development processes but also in human aging, the development of melanoma, wound healing, and even in the browning of fruits and vegetables.

Journal Highlight: Aqueous and lipid nuclear magnetic resonance metabolomic profiles of the earthworm Aporrectodea caliginosa show potential as an indicator species for environmental metabolomics

Date: Nov 5, 2014

Author: spectroscopyNOW

The aqueous and lipid metabolites in Aporrectodea caliginosa have been examined using high-resolution 1- and 2-dimensional nuclear magnetic resonance spectroscopy, allowing worms from different sites to be distinguished.

Collagen connection: The sticky ends

Date: Nov 1, 2014

Author: David Bradley

Discovering the secrets of collagen, a major component of connective tissue in mammals could lead to improved tissue engineering and cosmetic and reconstructive medicine. Researchers at Rice University have now used NMR spectroscopy to demonstrate how model collagen fibres self-assemble via their sticky ends.

Protein complex: The matter of the heart

Date: Oct 15, 2014

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy is offering important clues into how changes in protein structure present in heart failure impact the pumping action of the heart, suggesting new strategies for treating one of the biggest killers in the developed world.

Journal Highlight: Rapid assessment of the illegal presence of 1,3-dimethylamylamine (DMAA) in sports nutrition and dietary supplements using 1H NMR spectroscopy

Date: Oct 6, 2014

Author: spectroscopyNOW

A proton NMR method was developed and validated for measuring 1,3-dimethylamylamine in sports nutrition and dietary supplements and is recommended for routine use in food testing, customs or doping control laboratories.

Dynamic sugars: Sweet approach to behaviour

Date: Oct 1, 2014

Author: David Bradley

The dynamic behaviour of complicated sugar chains in solution has been followed at atomic resolution using a combination of a sophisticated nuclear magnetic resonance spectroscopic technique and a novel molecular dynamics simulation technique.

Planetary nano: Orbital system

Date: Sep 15, 2014

Author: David Bradley

German researchers have produced nanoparticles surrounded by a group of smaller nanoparticles in what might whimsically be described as a system resembling a tiny planet with orbiting satellites. Nuclear magnetic resonance spectroscopy and other techniques reveal the details.

Journal Highlight: Aluminum incorporation in the C–S–H phase of white portland cement–metakaolin blends studied by 27Al and 29Si MAS NMR spectroscopy

Date: Sep 1, 2014

Author: spectroscopyNOW

The composition and structure of the calcium-silicate-hydrate (C–S–H) phases formed by hydration of white portland cement–metakaolin (MK) blends have been investigated using 27Al and 29Si MAS NMR.
