Cool microscopy: Nobel chemistry

Date: Oct 15, 2017

Author: David Bradley

The development of cryo-electron microscopy has led to this year's Nobel Prize for Chemistry been awarded to Jacques Dubochet of the University of Lausanne, Switzerland, Joachim Frank of Columbia University, New York, USA, and Richard Henderson of the Medical research Council Laboratory of Molecular Biology (MRC-LMB) in Cambridge, UK.

Metals in meat: Bioavailability assessed by spectroscopy

Date: Oct 15, 2017

Author: David Bradley

Various techniques including graphite furnace atomic absorption spectrometry have been used to assess the bioavailability of metals ions present in beef, pork, and chicken after thermal treatment. The study shows that high temperatures make nutrient metal ions of calcium, copper, iron, magnesium and zinc less readily available.

Spot the difference: NMR technique for drug design

Date: Oct 15, 2017

Author: David Bradley

A powerful new NMR technique DiffErential EPitope mapping by STD NMR spectroscopy (DEEP-STD NMR) is being used by researchers in the UK to reveal the nature of the contact between ligand and protein target with a view to developing new pharmaceuticals with fewer side-effects.

Better bread and beer: Chemometric bakeoff

Date: Oct 15, 2017

Author: David Bradley

The use of multivariate data has allowed researchers from the Department of Food Science (FOOD) at the University of Copenhagen in Denmark to build a regression model of the analysis of whole grains at long near-infrared (NIR) wavelengths obtained with a supercontinuum laser. The research could improve our understanding of the chemistry of food ingredients with implications for improving bread and beer.

New 1.2 GHz NMR Spectrometers - New Horizons?

Date: Oct 3, 2017

Author: Prof. Dr. Harald Schwalbe

The latest ultrahigh-field NMR spectrometers are a huge technological challenge that require large financial investments. In his Guest Editorial written in the July issue of Angewandte Chemie, Harald Schwalbe justifies the need for spectrometers with higher magnetic field strengths. The important results from previous generations of high-field NMR spectrometers are discussed, and research areas are identified that will benefit from the latest spectrometers.
