NMR for celiac disease: metabonomic insights
Date: Jan 5, 2011
Author: David Bradley
Celiac disease (CD) is an autoimmune disorder caused by a permanent sensitivity to gluten in genetically susceptible individuals. A nuclear magnetic resonance spectroscopic approach to the disease could allow accurate and early diagnosis using metabonomics.

Optical alternative: light-based technique to complement NMR
Date: Dec 15, 2010
Author: David Bradley
New research published in The Journal of Chemical Physics introduces an alternative path to the nuclear information delivered by NMR by using light to observe the electrons in their orbitals around the nuclei and infer information about those nuclei indirectly.

Not a drop: buckyball bottles up single water molecule
Date: Dec 1, 2010
Author: David Bradley
Much of modern chemistry focuses on the incarceration of small molecules in cages and crypts. Now, a team writing in Angewandte Chemie describe how they have added a single water molecule to the world's smallest "bottle", a fullerene. NMR spectroscopy and X-ray diffraction reveal the details.

EPR spectroscopy: not to be sniffed out in deodorization
Date: Nov 1, 2010
Author: David Bradley
Electron paramagnetic resonance spectroscopy has allowed researchers to study how nanoparticles can eliminate offensive household odours by removing the odour molecules at source rather than simply masking the bad smells.

Cocaine smuggling: NMR spots illicit cocaine in wine
Date: Oct 14, 2010
Author: David Bradley
Nuclear magnetic resonance spectroscopy can be used to screen large cargos, such as cases of wine bottles, for the presence of illicit cocaine being smuggled in solution in the ethanol.

Turning up the NMR - Amplification technique boosts surface spectra
Date: Oct 1, 2010
Author: David Bradley
A technique to amplify nuclear magnetic resonance signals 50-fold or more can be applied to surfaces of solid-state samples, according to research published in the Journal of the American Chemical Society.

Calculating chemists
Date: Sep 15, 2010
Author: David Bradley
A new approach to the calculation of NMR spectra could help organic chemists identify stereoisomers of small, but complex molecules, much more quickly according to theoretical chemists at Cambridge University.

Novel pocket spotted
Date: Sep 1, 2010
Author: David Bradley
Researchers have identified a new class of chemicals that bind to a previously unknown allosteric pocket-a pocket outside the enzyme active site-and inhibit the enzyme FPPS. The work could have implications for new treatments of bone diseases, Paget's disease and tumour-induced bone degradation.

Dipolar Halbach magnet stacks made from identically shaped permanent magnets for magnetic resonance
Date: Aug 18, 2010
Author:
NMR Mandhalas (Magnetic Arrangement for Novel Discrete Halbach LAyout) are arrays of identically shaped magnets in a Halbach-type arrangement. They provide a simple and cost-effective way to generate high magnetic fields for mobile applications, for example, in magnetic resonance.

Fungal inspection
Date: Aug 15, 2010
Author: David Bradley
Two strains of microbial fungi isolated from soil and a commercial white-rot fungus have been tested for biodegradation of untreated, UV-, and heat-treated bisphenol A polycarbonate (PC) to see whether BPA release can be reduced. NMR and FTIR spectroscopy showed the formation of methyl groups due to the pre-treatment process, while EDAX analysis revealed surface oxidation of the PC.
