The UMIST database for astrochemistry 2012 [PDF]
Astronomy and Astrophysics, 2013 We present the fifth release of the UMIST Database for Astrochemistry (UDfA). The new reaction network contains 6173 gas-phase reactions, involving 467 species, 47 of which are new to this release. We have updated rate coefficients across all reaction types. We have included 1171 new anion reactions and updated and reviewed all photorates.

Metal-ion mediated photolytic regulation of diphenylalanine stability: Implications for prebiotic chemical evolution [PDF]
iScienceSummary: Early Earth’s UV-rich environment, together with abundant transition metals, likely shaped the stability of biomolecules. We investigated how cations influence the UV (254 nm) stability of diphenylalanine (FF).

Interrelations Between Astrochemistry and Galactic Dynamics
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.
