The path of biomolecular mass spectrometry into open research
Nature Communications, 2019 Originally designed for measuring isotope abundances and elemental masses, mass spectrometry is becoming a mainstay across life sciences. As electrospray ionization of biomolecules turns 30 and the Orbitrap mass analyzer 20, we take this opportunity to ...

Charge emissions from Electrosprays in vacuum: mixtures of formamide with methylammonium formate [PDF]
D. Garoz y J. Fernandez de la Mora, Journal of Applied Physics,
vol. 113, n. 6, pp. 064901-064901-8, feb. 2013The charge/mass distribution f(q/m) of nanodrops and ions electrosprayed in vacuum from mixtures of formamide (FM) and methylammonium formate (MAF) is studied by time of flight mass spectrometry at MAF/FM volumetric concentrations of 5%, 10%, 25% and 50%.

Heteroatomic jet fuel components: Lichen substances as fuel component and potential additives [PDF]
arXiv, 2018 This article presents chemical analysis of jet fuel (Jet A-1) heteroatomic fuel components with identification of an antioxidant lichen substance in methanol extracted fuel samples. Thermal stressing of jet fuel produces soluble macromolecular oxidatively reactive species (SMORS) and heteroatomic deposits.

TOWARDS THE PREPARATION OF CADMIUM CHALCOGEN CLUSTERS LINKED VIA DISELENOLATE LIGANDS [PDF]
, 2010 There are few examples of covalently linked cadmium chalcogen cluster assemblies and one route of extending this class of compounds is to explore the use of anionic ligands as linker molecules.

Relative affinity constants by electrospray ionization and Fourier transform ion cyclotron resonance mass spectrometry: calmodulin binding to peptide analogs of myosin light chain kinase [PDF]
, 2003 Synthetic RS20 peptide and a set of its point-mutated peptide analogs have been used to analyze the interactions between calmodulin (CaM) and the CaM-binding sequence of smooth-muscle myosin light chain kinase both in the presence and the absence of Ca2+.

Advanced Science, EarlyView.This study demonstrates that the atypical dehydrogenase/isomerase FabX in Type‐II fatty acid biosynthesis pathway is essential for H. pylori infection by retaining unsaturated fatty acid synthesis and producing superoxide (ROS). A small molecule FBX‐1991 that specifically targets FabX to inhibit H.
