Journal Highlight: Understanding surface and interfacial chemistry in functional nanomaterials via solid-state NMR

Date: May 1, 2017

Author: spectroscopyNOW

The use of solid-state NMR for the analysis of nanomaterials such as battery materials, nanocrystals, quantum dots, supramolecular assemblies, drug-delivery systems, ionomers and graphite oxides has been reviewed.

NMR reveals entropy redistribution: Bacterial proteins

Date: May 1, 2017

Author: David Bradley

Research carried out at the of the METACyt Biomolecular NMR Laboratory at IU Bloomington at Indiana University has revealed evidence that tiny changes in atomic movements in bacterial proteins can play a big role in how these microorganisms function and evolve.

NMR revision: Compound all at sea

Date: Apr 15, 2017

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy is a powerful tool and throws up chemical structure insights for even the most complex of natural products. Sometimes, however, those spectral lines can lead chemists to the wrong stereocentres and skeletons. An international team has now revised the structure of an important marine metabolite.

Anemones punch holes: Toxins by NMR

Date: Apr 1, 2017

Author: David Bradley

A new approach to constructing a sea anemone toxin makes it plausible to incorporate site-specific isotopic labels for solid-state nuclear magnetic resonance (NMR) spectroscopic structural studies that will ultimately reveal how it functions and provide clues as to the action of other pore-forming proteins.

What a difference a state makes: NMR curiosity

Date: Mar 15, 2017

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy has revealed how molecular self-assembly processes can take different forms of a supramolecular structure from the solution state to the solid state and back again, a phenomenon identified for the first time by researchers at the University of Warwick, UK.

Reversing resistance: Rose myrtle extracts analysed by NMR

Date: Mar 1, 2017

Author: David Bradley

Novel natural products found in rose myrtle could hold promise of a new way to make breast cancer cells that have become resistant to the conventional anticancer drug doxorubicin susceptible once more. Nuclear magnetic resonance (NMR) spectroscopy, electronic circular dichroism (ECD) and X-ray crystallography were used to determine the structures and absolute configurations of the compounds.

Portable superconductors: Boost for NMR and MRI

Date: Feb 15, 2017

Author: David Bradley

The confluence of novel materials and a pioneering US discovery with innovation in cryogenics could soon lead to portable and lower-cost NMR and MRI machines, thanks to work at Cambridge University.

Solvents and skin: Solid state NMR of fluid molecules

Date: Feb 1, 2017

Author: David Bradley

Swedish scientists have used solid state nuclear magnetic resonance (NMR) spectroscopy to investigate how individual organic solvent molecules used in skin creams, medicated ointments and cleaning products interact with the biochemistry of human skin and whether or not they can enter the skin.
