The Advion expression compact mass …

Authors: Max Planck Institute for Polymer Research, Germany; University of Twente, Netherlands Abstract We developed a simple way to create 2D conductive nanostructures with dielectric cores and conductive surfaces based on polyethylene with in-chain thiophene groups. Generally, thiophene-based polymers show great conductive properties, but exhibit a poor processability. Here, we use the crystallization of a …

Authors: University of Birmingham, United Kingdom Abstract The ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter cloacae) represent clinically important bacterial species that are responsible for most hospital-acquired drug-resistant infections; hence, the need for rapid identification is of high importance. Previous work has demonstrated the suitability of liquid extraction …

AstraZeneca, United Kingdom Abstract Deuterium exchange has been demonstrated to provide additional information to accurate mass measurement and collision‐induced dissociation on unknown chemical structures. An enhanced method for rapid deuterium exchange could make this technique more routine for structural elucidation. Open port sampling interface mass spectrometry (OPSI‐MS) with an aprotic solvent offers a rapid method …

Institute of Food Research, Genome Analysis Center, Aix-Marseille University, University of East Anglia Abstract We previously identified and characterized an intramolecular trans-sialidase (IT-sialidase) in the gut symbiont Ruminococcus gnavus ATCC 29149, which is associated to the ability of the strain to grow on mucins.
