Prostate cancer: NMR determines aggressiveness

Date: Apr 15, 2018

Author:

Nuclear magnetic resonance (NMR) spectroscopy could help solve a commonly intractable medical problem: how to determine the aggressiveness of prostate cancer. The new approach could help oncologists identify which tumours could be life threatening and need radical treatment

Pnictogen, chalcogen, halogen: NMR looks into the blue holes

Date: Apr 1, 2018

Author:

New catalysts containing antimony could complement more well-known interactions such as hydrogen bonds or chalcogen-sulfur bonds in chemical reactions for a wide range of products. Nuclear magnetic resonance (NMR) spectroscopy provides the clues.

Magnetic interaction: NMR measures

Date: Mar 15, 2018

Author: David Bradley

An international team has proposed a solution to the "hyperfine puzzle" raised in 2017. The researchers report new NMR measurements of the magnetic properties of bismuth atomic nuclei in the journal Physical Review Letters.

Journal Highlight: Medium resolution 1H-NMR at 62 MHz as a new chemically sensitive online detector for size-exclusion chromatography (SEC–NMR)

Date: Mar 5, 2018

Author: spectroscopyNOW

A state-of-the-art, medium-resolution 1H-NMR spectrometer (62 MHz) has been used as a chemically sensitive online detector for the SEC of polymers such as polymethylmethacrylate, polystyrene and polymer blends.

Dynamic channels: NMR tracks the ions

Date: Mar 1, 2018

Author: David Bradley

Researchers in Germany have demonstrated using nuclear magnetic resonance (NMR) spectroscopy how the selectivity filter of the cell membrane's NaK protein ion channel forms only a single structure to control the flow of potassium ions.

Magnetic benchmark: Record-breaking thin film

Date: Feb 15, 2018

Author: David Bradley

US researchers have developed a new magnetic thin film that could finally break through the Slater-Pauling limit on magnetic density in a material. With this decades-old benchmark circumvented new applications and devices might be possible.

Amyotrophic lateral sclerosis: NMR spots atomic changes

Date: Feb 1, 2018

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy has been used to reveal for the first time the atom-by-atom changes that take place in a family of proteins associated with amyotrophic lateral sclerosis (ALS). This group of lethal brain disorders leads to frontotemporal dementia and degenerative diseases of muscle and bone.

Journal Highlight: A review of NMR methods used in the study of the structure and dynamics of ionic liquids

Date: Jan 29, 2018

Author: spectroscopyNOW

This mini-review presents a brief research summary of the applications of NMR spectroscopy to the structure and dynamics of pure ionic liquids and their mixtures with lithium salts.

The dawn of life: NMR has (some of) the details

Date: Jan 15, 2018

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy and other techniques have been used to study the linked cycles of oxidative decarboxylation of glyoxylate. Such cycles could be perceived as being proto-metabolic analogues of the citric acid cycle on which life depends and might provide a new clue as to how life on earth emerged from the primordial soup.
