Playing protein tag: Repeatable NMR

Date: Oct 1, 2012

Author: David Bradley

Chemists at the University of California San Diego have developed a method that allows them, for the first time, to attach chemical probes on to proteins and remove them again in a straightforward and repeatable cycle. The method will facilitate NMR spectroscopy for metabolic and other research studies.

MOFs: NMR reveals inner secrets

Date: Sep 15, 2012

Author: David Bradley

A large international research team from Canada and China has shown for the first time that zinc-67 solid-state NMR spectroscopy could be as useful in analysing the zinc atom centres in a new type of synthetic porous materials known as metal-organic frameworks (MOFs) as its aluminium-based counterpart, aluminium-27 NMR is in studying the more widely known natural porous zeolite minerals.

Journal Highlight: Applications of NMR metabolomics to the study of foodstuffs: Truffle, kiwifruit, lettuce, and sea bass

Date: Sep 3, 2012

Author: spectroscopyNOW

The use of NMR to study the metabolomes of foodstuffs of different origin (truffle, kiwifruit, lettuce, sea bass) with different metabolite compositions, processing, and storage procedures, is reviewed.

Move like caged hydrogen: Buckyball traps

Date: Sep 1, 2012

Author: David Bradley

Cryogenic NMR spectroscopy and other techniques has been used to investigate how small molecules, including water, are trapped by the all-carbon cages known as fullerenes. The work might open up the possibility of using such caged systems as alternative contrast agents for magnetic resonance imaging.

Supercritical carbon dioxide: Forming formic acid

Date: Aug 15, 2012

Author: David Bradley

Carbon dioxide can be both starting material for the production of formic acid through hydrogenation and also the solvent for the reaction if held in the supercritical; the usual complexities of extraction of product from solvent essentially removed as the solvent can be evaporated by simply releasing the pressure from the system and trapping the carbon dioxide gas released. NMR spectroscopy allows the German inventors of the process to keep track of reactants and products.

Journal Highlight: Comparison of the metabolic profiling of hepatitis B virus-infected cirrhosis and alcoholic cirrhosis patients by using 1H NMR-based metabonomics

Date: Aug 6, 2012

Author: spectroscopyNOW

Proton NMR was used to reveal the serum metabolic characteristics of hepatitis B virus-infected cirrhosis and alcoholic cirrhosis patients and to find the specific serum biomarkers associated with the diseases.

Stellar effort: New chemical bond revealed

Date: Aug 1, 2012

Author: David Bradley

Quantum mechanics calculations suggest that the intense magnetic field around a type of fast-spinning, high-density star known as a white dwarf might be strong enough to distil a new type of chemistry.
