Interrelations Between Astrochemistry and Galactic Dynamics [PDF]

open access: yesFrontiers in Astronomy and Space Sciences, 2021
This paper presents a review of ideas that interconnect astrochemistry and galactic dynamics. Since these two areas are vast and not recent, each one has already been covered separately by several reviews.

Dipeptide photodegradation under copper ion influence suggests protective second-shell design in copper-binding proteins [PDF]

open access: yesBMC Chemistry
The evolutionary origin of copper-binding proteins remains a central question in prebiotic chemistry. Modern copper proteins predominantly coordinate copper through histidine and cysteine residues, suggesting that these amino acids were selectively ...

Data-Driven UPLC-Orbitrap MS Analysis in Astrochemistry

open access: yesLife, 2019
Meteorites have been found to be rich and highly diverse in organic compounds. Next to previous direct infusion high resolution mass spectrometry experiments (DI-HR-MS), we present here data-driven strategies to evaluate UPLC-Orbitrap MS analyses.

Enhanced Resolution in EPR Spectroscopy Using para-Hydrogen Matrices. [PDF]

open access: yesAngew Chem Int Ed Engl
We demonstrate the advantageous properties of solid para‐hydrogen (p‐H2) matrices for electron paramagnetic resonance (EPR) spectroscopy by investigating the 2,2,6,6‐tetramethylpiperidinyloxyl (TEMPO) radical and an in situ generated P‐centered mono‐radical.

Geochemistry of the cretaceous-tertiary transition boundary at Blake Nose (N. W. Atlantic): Cosmogenic Ni [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
The Cretaceous-Tertiary (KT) boundary transition at the Blake Nose Plateau recovered by ODP Leg 171B (site 1049, hole A, core 17X, section 2) contains an ejecta bed (thickness ca. 17 cm) marking a late Cretaceous asteroid impact.
