Mass Spectrometry Imaging of Lipids Using MALDI Coupled with Plasma-Based Post-Ionization on a Trapped Ion Mobility Mass Spectrometer
Autor: Jesse A. Michael, Shadrack M. Mutuku, Boris Ucur, Tassiani Sarretto, Alan T. Maccarone, Marcel Niehaus, Adam J. Trevitt, Shane R. Ellis
Publikováno v: Analytical Chemistry. 94:17494-17503
Here we report the development and optimization of a mass spectrometry imaging (MSI) platform that combines an atmospheric-pressure matrix-assisted laser desorption/ionization platform with plasma postionization (AP-MALDI-PPI) and trapped ion mobilit

The (O-acyl)-ω-hydroxy FAs (OAHFAs) comprise an unusual lipid subclass present in the skin, vernix caseosa, and meibomian gland secretions. Although they are structurally related to the general class of FA esters of hydroxy FAs (FAHFAs), the ultra-l

UV/VUV photoprocessing of protonatedN-hetero(poly)acenes
Autor: Ugo Jacovella, Christopher S Hansen, Alexandre Giuliani, Adam J Trevitt, Laurent Nahon
Publikováno v: Monthly Notices of the Royal Astronomical Society. 511:5656-5660
N-heterocycles are suspected to play an important role in the chemical origin of life. Despite their detection in meteorites and in Titan’s atmosphere, their extra-terrestrial chemical formation networks remain elusive. Furthermore N-heterocyclics

UV photodissociation action spectra of protonated formylpyridines
Autor: Benjamin I. McKinnon, Samuel J. P. Marlton, Jordan Dezalay, Satchin Soorkia, Stephen J. Blanksby, Adam J. Trevitt
Publikováno v: The Journal of chemical physics. 157(13)
The first ππ* transition for protonated 2-, 3-, and 4-formylpyridine (FPH+) ( m/z 108) is investigated by mass spectrometry coupled with photodissociation action spectroscopy at room temperature and 10 K. The photoproduct ions are detected over 35

Modelling reaction kinetics of distonic radical ions: a systematic investigation of phenyl-type radical addition to unsaturated hydrocarbons
Autor: Oisin J. Shiels, Jack A. Turner, P. D. Kelly, Stephen J. Blanksby, Gabriel da Silva, Adam J. Trevitt
Publikováno v: Faraday discussions. 238
Gas phase ion-molecule reactions are central to chemical processes across many environments. A feature of many of these reactions is an inverse relationship between temperature and reaction rate arising from a submerged barrier (an early reaction bar

Reactivity Trends in the Gas-Phase Addition of Acetylene to the N-Protonated Aryl Radical Cations of Pyridine, Aniline, and Benzonitrile
Autor: Cameron C. Bright, Oisin J. Shiels, Stephen J. Blanksby, Berwyck L. J. Poad, Gabriel da Silva, Adam J. Trevitt, Patrick D Kelly
Publikováno v: Journal of the American Society for Mass Spectrometry. 32:537-547
A key step in gas-phase polycyclic aromatic hydrocarbon (PAH) formation involves the addition of acetylene (or other alkyne) to σ-type aromatic radicals, with successive additions yielding more complex PAHs. A similar process can happen for N-contai

Publikováno v: Physical Chemistry Chemical Physics. 23:14913-14924
Gas-phase reactions of the o-methylphenyl (o-CH3C6H4) radical with the C3H4 isomers allene (H2C[double bond, length as m-dash]C[double bond, length as m-dash]CH2) and propyne (HC[triple bond, length as m-dash]C-CH3) are studied at 600 K and 4 Torr (5
