Astrochemistry

Plasma Sources Science and Technology, 2015
In the last 40 years a wide range of molecules, including neutrals, cations and anions, containing up to 13 atoms—in addition to detections of C60 and C70 — have been found in the harsh environment of the interstellar medium. The exquisite sensitivity and very high spectral and, more recently, spatial resolution, of modern telescopes has enabled the ...

Ion Source Complementarity for Characterization of Complex Organic Mixtures Using Fourier Transform Mass Spectrometry: A Review

Mass Spectrometry Reviews, Volume 44, Issue 5, Page 808-829, September/October 2025.
ABSTRACT Complex organic mixtures are found in many areas of research, such as energy, environment, health, planetology, and cultural heritage, to name but a few. However, due to their complex chemical composition, which holds an extensive potential of information at the molecular level, their molecular characterization is challenging.

The largest oxigen bearing organic molecule repository

, 2007
We present the first detection of complex aldehydes and isomers in three typical molecular clouds located within 200pc of the center of our Galaxy. We find very large abundances of these complex organic molecules (COMs) in the central molecular zone ...

The Genuine Carbene Conundrum

Chemistry – A European Journal, Volume 31, Issue 44, August 7, 2025.
From fleeting intermediates to well‐defined molecular structures, carbenes (neutral divalent carbon) remind us that the most reactive ideas often make a large impact. Despite their wide‐ranging applications, the direct characterization of these reactive species remains a persistent experimental challenge.

Warm Cores around Regions of Low-Mass Star Formation

, 2010
Warm cores (or hot corinos) around low-mass protostellar objects show a rich chemistry with strong spatial variations. This chemistry is generally attributed to the sublimation of icy mantles on dust grains initiated by the warming effect of the stellar ...

Neutrals Ejected From Io's Plasma/Atmosphere Interaction Region by Physical Chemistry Processes

Journal of Geophysical Research: Space Physics, Volume 130, Issue 8, August 2025.
Abstract Neutrals ejected from Io's atmosphere are the source of many important structures of the jovian magnetosphere: they feed giant neutral clouds, which extend along Io's orbit and nebulae, which extend beyond 500 jovian radii. The neutral loss rate is casually claimed to be ∼1 ton/s, but the processes leading to this loss, their quantitative ...

Efficient calculation of van der Waals dispersion coefficients with time-dependent density functional theory in real time: application to polycyclic aromatic hydrocarbons

, 2007
The van der Waals dispersion coefficients of a set of polycyclic aromatic hydrocarbons, ranging in size from the single-cycle benzene to circumovalene (C66H20), are calculated with a real-time propagation approach to time-dependent density functional ...

Mapping adsorption on ionic surfaces via a pairwise potential‐based high‐throughput approach

Journal of Applied Crystallography, Volume 58, Issue 4, Page 1462-1468, August 2025.
This work presents a high‐throughput method for predicting molecular adsorption sites on ionic surfaces using pairwise Coulomb and Lennard–Jones potentials. Requiring only a CIF as input, the approach enables rapid identification of stable adsorption structures, offering an efficient pathway for studying complex surface–adsorbate interactions ...
