Interrelations Between Astrochemistry and Galactic Dynamics [PDF]
Frontiers 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.

Enhanced Resolution in EPR Spectroscopy Using para-Hydrogen Matrices. [PDF]
Angew Chem Int Ed EnglWe 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.

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