Systems Astrochemistry: A New Doctrine for Experimental Studies

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Laboratory experiments play a key role in deciphering the chemistry of the interstellar medium (ISM) and the formation of complex organic molecules (COMs) relevant to life.

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 ...

Metal-ion mediated photolytic regulation of diphenylalanine stability: Implications for prebiotic chemical evolution [PDF]

open access: yesiScience
Summary: 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

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.

Future space experiment platforms for astrobiology and astrochemistry research

open access: yesnpj Microgravity, 2023
Space experiments are a technically challenging but a scientifically important part of astrobiology and astrochemistry research. The International Space Station (ISS) is an excellent example of a highly successful and long-lasting research platform for ...

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.

Infrared Spectra and Vapor Pressures of Crystalline C2N2, with Comparisons to Crystalline HCN

open access: yesThe Planetary Science Journal, 2023
In a continuation of our work on nitriles, we have examined cyanogen (C _2 N _2 ) as a crystalline solid, comparing the results to our recent work on crystalline hydrogen cyanide (HCN).

AlF–AlF Reaction Dynamics between 200 K and 1000 K: Reaction Mechanisms and Intermediate Complex Characterization

open access: yesMolecules, 2023
AlF is a relevant molecule in astrochemistry as a tracer of F-bearing molecules. Additionally, AlF presents diagonal Franck-Condon factors and can be created very efficiently in the lab, which makes it a prototypical molecular for laser cooling. However,
