The Photodissociation and Ionization Fronts in M17-SW Localized with FIFI-LS on Board SOFIA
The Astrophysical Journal, 2023 To understand star formation rates, studying feedback mechanisms that regulate star formation is necessary. The radiation emitted by nascent massive stars play a significant role in feedback by photodissociating and ionizing their parental molecular ...

First 20 Years of Orbitrap Mass Spectrometry as the Mainstream Analytical Technique
Mass Spectrometry Reviews, EarlyView.ABSTRACT This review traces the first 20 years of Orbitrap mass spectrometry as a mainstream high‑resolution and accurate‑mass (HR/AM) technology. It outlines the historical development of the Orbitrap analyzer, the evolution of major instrument families, and the key technological innovations that enabled its widespread adoption. Particular emphasis is

Recent Advances in Top‐Down Proteomics for Single‐Cell Research
Mass Spectrometry Reviews, EarlyView.ABSTRACT Individual cells have distinctive molecular characteristics, including biologically relevant proteoforms. Although single‐cell (SC) molecular omics offer unprecedented insights into cellular heterogeneity and function, the characterization of proteoforms in SCs remains an uncharted territory.

Nonadiabatic photodissociation dynamics
, 2005 The photodissociation dynamics of the triatomic (or pseudo-triatomic) system in the nonadiabatic multiple electronic states is investigated by employing a time-dependent quantum wavepacket method, while the time propagation of the wave packet is carried ...

Simulating cold atomic hydrogen production in linear radiofrequency ion traps
New Journal of PhysicsWe simulated the motion of ${\mathrm{BaH^{+}}}$ molecular ions which are sympathetically cooled by laser-cooled ${\mathrm{Ba^{+}}}$ ions in linear quadrupole and octupole radiofrequency (RF) ion traps.
