Electronic fluorescence spectra of gas-phase positive molecular ions
, 1980 A new technique for observing electronic spectra of gas-phase positive molecular ions is described. The ions are produced by electron impact on a supersonic molecular beam, and the resulting fluorescent radiation is dispersed. Some results on N2, N2O and

Wake potential with mobile positive/negative ions in multicomponent dusty plasmas
, 2008 We employ the test charge approach to calculate the electrostatic potential for a test charge in a multicomponent dusty plasma, whose constituents are the Boltzmann distributed electrons, mobile positive and negative ions, and immobile positive/negative ...

FEBS Open Bio, EarlyView.In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

A theoretical model of the stratospheric positive ions
, 1987 A simple model is proposed to reproduce the features of the stratospheric ion composition and density revealed by recent measurements. Where reaction rates are not known, they have been substituted by a lumped parameter which is adjusted to conform to ...

Measuring development’s ‘ions’ [PDF]
, 2013 When it comes to measuring ions, natural scientists have it easier than those working in international development. In natural science, defining ions and determining whether one is negative or positive is a basic process.

Electron and laser interactions with positive ions
, 1999 Recent progress in laboratory-based electron-ion scattering is reviewed, and the sensitivity of observed interference structure as a probe of collision dynamics is discussed.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum
FEBS Open Bio, EarlyView.Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity
FEBS Open Bio, EarlyView.Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

FEBS Open Bio, EarlyView.TGF‐β1 stimulation downregulates lysosomal channel TRPML1 in pulmonary fibroblasts. The TRPML1 agonist ML‐SA5 suppressed fibroblast‐to‐myofibroblast activation and collagen production. Mechanistically, ML‐SA5 inhibited mTOR phosphorylation, restored autophagic flux, and its effects were enhanced by rapamycin (mTOR inhibitor) and reversed by MHY1485 ...
