Chiral anomaly: An end to decades-long hunt

Date: Sep 15, 2015

Author: David Bradley

The 'chiral anomaly' was first posited in the 1960s and suggested to exist in crystalline materials in the 1980s but has only now been detected by conductivity measurements in a semi-metal compound of sodium and bismuth.

Spin me right round: Ortho-Para water

Date: Sep 1, 2015

Author: David Bradley

Research by an interdisciplinary team including chemists, physicists and engineers from the University of Southampton has found that water molecules react differently to electric fields, which could provide a new way to study spin isomers at the single-molecule level and offer new insights to the phenomenon of magnetic resonance.

NMR reveals cancer clue: p53 activity

Date: Aug 15, 2015

Author: David Bradley

US researchers have used NMR spectroscopy in a study of the activity of the tumour suppressor protein, p53. Their work reveals the mechanism by which p53 triggers programmed cell death (apoptosis) and may have implications for understanding the development of various forms of cancer and perhaps lead to new drug discoveries.

Journal Highlight: NMR data visualization, processing, and analysis on mobile devices

Date: Aug 3, 2015

Author: spectroscopyNOW

A new NMR app has been designed for hand-held and portable touch-controlled devices, such as smartphones and tablets, featuring flexible architecture formed by a powerful NMR processing and analysis kernel and an intuitive user interface.

I should OCCO: Spectral structure

Date: Aug 1, 2015

Author: David Bradley

Photoelectron imaging spectroscopy has been used to characterise a seemingly simpl molecule that has remained elusive since its structure was first mooted in 1913, ethylenedione, OCCO.

NMR boost: Supercapacitors

Date: Jul 1, 2015

Author: David Bradley

Nuclear magnetic resonance spectroscopy has allowed researchers in France, the UK and the US to visualize the activity of individual ions  within battery-like devices known as supercapacitors, which could lead to performance-boosting developments for high-power applications.

Journal Highlight: NMR-based approach to the analysis of radiopharmaceuticals: radiochemical purity, specific activity, and radioactive concentration values by proton and tritium NMR spectroscopy

Date: Jun 29, 2015

Author: spectroscopyNOW

Calibrated 3H and 1H NMR spectroscopy could be used as a supplemental or replacement approach for assessing the purity, radioactivity levels and specific activity of radiopharmaceuticals.

Separation anxiety: Magnetic metal recycling

Date: Jun 15, 2015

Author: David Bradley

Rare earth magnets are widely used in a range of gadgets, instrumentation and even toys but recycling the mixtures of metals from which the magnets are formed is difficult. Now, research published in the journal Angewandte Chemie offers a novel approach to the isolation of neodymium and dysprosium from dismantled magnets. The technique could ward off a future shortage of these metals.
