Kinetic Study on the Reactions of Hydroxyl Radical with 1‐butene, Isobutene, and Trimethylpentene: Temperature and Pressure Dependence

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT The temperature dependence of the reaction rate coefficients (k) for the reactions of hydroxyl radical with three alkenes was measured by using laser‐induced fluorescence techniques in the temperature range of 298–750 K. The negative temperature dependence of k was observed for each reaction in the low‐pressure range.

Ion Activation Methods for Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Nonadiabatic photodissociation dynamics

open access: yes, 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 ...

Recent Advances in Top‐Down Proteomics for Single‐Cell Research

open access: yesMass 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.

Models of clumpy photodissociation regions

open access: yesThe Astrophysical Journal, 1993
FIR fine structure line and submillimeter line emissions important in the cooling of photodissociation regions (PDRs) as they would arise in clumpy regions are investigated with a simple two-component model for clumpy PDRs consisting of high-density clumps embedded in a lower density interclump medium.
