2013 journal article

Analysis of xyloglucans by ambient chloride attachment ionization tandem mass spectrometry

Carbohydrate Polymers, 98(1), 1203–1213.

By: N. Vinueza*, V. Gallardo*, J. Klimek*, N. Carpita* & H. Kenttämaa*

author keywords: Xyloglucans; Electrospray ionization; Chloride attachment; Tandem mass spectrometry; Hymenaea courbaril, Arabidopsis thaliana mur3; Sequencing
MeSH headings : Arabidopsis / genetics; Arabidopsis / metabolism; Chlorides / metabolism; Galactosyltransferases / genetics; Galactosyltransferases / metabolism; Glucans / chemistry; Glucans / metabolism; Hymenaea / metabolism; Mutation; Polymerization; Tandem Mass Spectrometry; Xylans / chemistry; Xylans / metabolism
TL;DR: The mass spectral profile of xyloglucans obtained for the mixtures matches the HPAEC results, thus validating this methodology for the determination of the xylglucan composition and the MW of each xylogucan. (via Semantic Scholar)

On-Line Mass Spectrometric Methods for the Determination of the Primary Products of Fast Pyrolysis of Carbohydrates and for Their Gas-Phase Manipulation

Analytical Chemistry, 85(22), 10927–10934.

By: M. Hurt*, J. Degenstein*, P. Gawecki*, D. Borton II, N. Vinueza*, L. Yang*, R. Agrawal*, W. Delgass*, F. Ribeiro*, H. Kenttämaa*

TL;DR: The primary fast pyrolysis products were determined to consist of only a handful of compounds that quickly polymerize to form anhydro-oligosaccharides when allowed to react at high temperatures for an extended period of time. (via Semantic Scholar)

2013 journal article

Does the 2,6-didehydropyridinium cation exist?

Journal of Physical Organic Chemistry, 26(9), 707–714.

author keywords: Didehydrobenzene; FT-ICR; biradicals; ion-molecule reactions; reactive intermediates
TL;DR: The results suggest that a mixture of singlet (ground) state and triplet (excited) state 2,6-didehydropyridinium cations was generated and the two different states show qualitatively different reactivity, with the triplet state showing greater Brønsted acidity than that of the singlet state.

Experimental and Computational Studies on the Formation of Threepara-Benzyne Analogues in the Gas Phase

Chemistry - A European Journal, 19(27), 9022–9033.

By: L. Kirkpatrick*, N. Vinueza*, B. Jankiewicz*, V. Gallardo*, E. Archibold*, J. Nash*, H. Kenttämaa*

author keywords: biradicals; distonic ions; ion-molecule reactions; para-benzyne; mass spectrometry; ring-opening
MeSH headings : Antibiotics, Antineoplastic / chemistry; Benzene Derivatives / chemistry; Cations; Fourier Analysis; Gases; Indicators and Reagents; Isomerism; Isoquinolines / chemistry; Mass Spectrometry / methods; Nitriles / chemistry; Pyridines / chemistry; Quantum Theory; Thermodynamics
TL;DR: A theoretical study on possible rearrangement reactions occurring during CAD revealed that the cation formed upon the first iodine atom loss undergoes ring-opening before the second iodine atom Loss to form an enediyne instead of a para-benzyne, which is in contradiction with an earlier report on this cation.

Direct Analysis of Textile Fabrics and Dyes Using Infrared Matrix-Assisted Laser Desorption Electrospray Ionization Mass Spectrometry

ANALYTICAL CHEMISTRY, 85(2), 831–836.

MeSH headings : Coloring Agents / analysis; Spectrometry, Mass, Matrix-Assisted Laser Desorption-Ionization; Textiles / analysis
TL;DR: A direct analysis of dyed textile fabric was performed using the infrared matrix-assisted laser desorption electrospray ionization (IR-MALDESI) source for MS, allowing the omission of the lengthy sample preparation involved in extraction, thereby significantly reducing the overall analysis time.

Design, Synthesis, and Pharmacological Screening of Novel Porphyrin Derivatives

JOURNAL OF CHEMISTRY, 2013.

By: A. Fadda*, R. El-Mekawy*, A. El-Shafei n, H. Freeman n, D. Hinks n & A. El-Fedawy*

TL;DR: It was demonstrated that these dyes were effective in the inhibition of the free radical-induced oxidative haemolysis of rat blood cells and excellent correlation between the LUMO energy and cytotoxicity of dyes 2a–f was found. (via Semantic Scholar)
