Journal ArticleDOI
Particle phase acidity and oligomer formation in secondary organic aerosol.
Song Gao,Nga L. Ng,Melita Keywood,Varuntida Varutbangkul,Roya Bahreini,Athanasios Nenes,Jiwen He,Kee Y. Yoo,Jesse L. Beauchamp,Robert Hodyss,Richard C. Flagan,John H. Seinfeld +11 more
TL;DR: As the seed particle acidity increases, larger oligomers are formed more abundantly in the SOA; consequently, the overall SOA yield also increases, and this explicit effect of particle phase acidity on the composition and yield of SOA may have important climatic consequences and need to be considered in relevant models.
Journal ArticleDOI
Titan tholins: simulating Titan organic chemistry in the Cassini-Huygens era.
Morgan L. Cable,Sarah M. Hörst,Robert Hodyss,Patricia Beauchamp,Mark A. Smith,Mark A. Smith,Peter Willis +6 more
TL;DR: Titan Tholins: Simulating Titan Organic Chemistry in the Cassini-Huygens Era is presented, which aims to provide a simulation framework for future generations of space missions to Jupiter and Saturn.
Journal ArticleDOI
Bioconjugates for tunable peptide fragmentation : Free radical initiated peptide sequencing (FRIPS)
TL;DR: Data is presented for the Angiotensin II-Vazo 68 conjugate and possible sites of H atom abstraction from the peptide are discussed, as in CAD of other radical peptides and ECD fragmentation.
Journal ArticleDOI
Nanocrystalline Aggregation of Serine Detected by Electrospray Ionization Mass Spectrometry: Origin of the Stable Homochiral Gas-Phase Serine Octamer
TL;DR: In this article, the formation, bonding, and experimental constraints placed on the serine octamer are discussed in light of the proposed nanocrystalline structure, and implications for the spontaneous symmetry breaking of a racemic mixture and the origin of life are addressed.
Journal ArticleDOI
Salt Bridge Stabilization of Charged Zwitterionic Arginine Aggregates in the Gas Phase
TL;DR: Quadrupole ion-trap mass spectrometry provides evidence for the stability of arginine in the zwitterionic state, where the protonated guanidinium group of oneArginine interacts strongly with the carboxylate of another to form stable noncovalent complexes, coordinated to either a cation or anion.
