AlF–AlF Reaction Dynamics between 200 K and 1000 K: Reaction Mechanisms and Intermediate Complex Characterization [PDF]
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,

Cosmic-Ray Induced Diffusion in Interstellar Ices
Cosmic rays are able to heat interstellar dust grains. This may enhance molecule mobility in icy mantles that have accumulated on the grains in dark cloud cores.

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

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