Fine sediments, often due to run-off from the land, can clog the surface and sub-surface spaces in gravel beds used by spawning fish to lay their eggs and by aquatic insects. Without an adequate flow of oxygenated water, the eggs and insects die. Heather Haynes, Susithra Lakshmanan, Anne-Marie Ockelford, Elisa Vignaga and William Holmes tells us about this in “The emerging use of magnetic...
Bruker has announced five orders for ultra-high field (UHF) nuclear magnetic resonance (NMR) spectroscopy systems from Europe and Brazil in recent months. These UHF systems have been funded for cutting-edge NMR research in structural biology, intrinsically disordered proteins (IDPs), membrane proteins, macro-molecular complexes and interactions, cell biology, disease research, as well as in...
A new electron paramagnetic resonance (EPR) spectroscopy method is bringing researchers at Rensselaer Polytechnic Institute (RPI) closer to understanding—and artificially replicating—the solar water-splitting reaction at the heart of photosynthetic energy production.
Deutero have introduced a simple glass funnel suitable for 5-mm NMR tubes, and applicable for filling powder.

Tony Davies and Mohan Cashyap are concerned about your NMR data. When an article starts “On 10 October 2014 the impossible happened”, you will want to take note! Following the withdrawal of Agilent from the NMR business, Tony and Mohan consider three solutions to ensuring your NMR data is available now and into the future. If you have an NMR of any make, you will want to read this. Do remember...
Mathieu Duval raises the question “Dating fossil teeth by electron paramagnetic resonance: how is that possible?”. Whilst we are all familiar with 14C dating, the use of EPR is less well known. In fact, there are less than 10 laboratories in the world able to carry out EPR dating of fossil teeth!
“Rheo-nuclear magnetic resonance spectroscopy: a versatile toolbox to investigate rheological phenomena in complex fluids” is Claudia Schmidt’s topic. Rheology is an important science, and NMR has a number of uses within it. However, challenges remain for the simultaneous measurement of rheological and NMR parameters.
Many analytical methods have been used to control the quality, authenticity and origin of fresh fruit. NMR methodologies yield a comprehensive metabolic profile, provide direct structural information regarding individual metabolites in the mixture and also give information regarding the water state in the tissue. This is useful in discriminating various fruits varieties, in investigating...
Peter Jenks has discovered quantitative NMR. in his article titled “NMR: is it the future for the analysis of organic molecules?”. If only it wasn’t so expensive, it might be the perfect method to certify pure organic compounds.
Nuclear magnetic resonance (NMR) spectroscopy is one of the most powerful analytical tools used to probe details of molecular structure and dynamics. It requires very high magnetic fields and, hence, generally uses extremely large, powerful magnets. The advent of small, powerful magnets has allowed much less expensive low resolution NMR instrumentation to be designed, making it feasible to...
1H NMR spectra are usually interpreted by hand, which is very time consuming, and can become a process bottleneck in fields such as high-throughput NMR. Greater automation of the spectral analysis process has become essential if NMR is to be of value as a high-throughput analytical method in the future.
Dirk Lachenmeier, Marina Gary, Yulia Monakhova, Thomas Kuballa and Gerd Mildau describe “Rapid NMR screening of total aldehydes to detect oxidative rancidity in vegetable oils and decorative cosmetics”. Lipid oxidation produces rancid products, which are both unpleasant and potentially toxic. The authors describe the use of NMR to screen food and cosmetic products. Whilst, vegetable oils were...

In 1946, two scientists in the United States, independently of each other, described a physicochemical phenomenon that was based upon the magnetic properties of certain nuclei in the periodic system. This was “nuclear magnetic resonance”, for short...

The purpose of this short review article is to highlight some capabilities of qNMR spectroscopic methods in drug quality evaluation, indicating that qNMR spectroscopy should be more often applied when chromatographic methods are not working effectively.
Our focus here is analytical procedures, and the role of nuclear magnetic resonance (NMR) in particular. These have, until now, largely relied on conventional chromatography, and vibrational spectroscopy—infrared (IR), Raman and near infrared (NIR) spectroscopy. In spite of inherent difficulties with peak assignment and reliable quantification, vibrational spectroscopy has been used to derive...
