Planets form and obtain their compositions in disks of gas and dust around young stars. The
chemical compositions of these planet-forming disks regulate all aspects of planetary …

Star-forming regions show a rich and varied chemistry, including the presence of complex
organic molecules—in both the cold gas distributed on large scales and the hot regions …

Unidentified infrared emission bands are ubiquitous in many astronomical sources. These
bands are widely, if not unanimously, attributed to collective emissions from polycyclic …

We report the detection for the first time in space of three new pure hydrocarbon cycles in
TMC-1: cC 3 HCCH (ethynyl cyclopropenylidene), cC 5 H 6 (cyclopentadiene), and cC 9 H 8 …

Non-thermal Plasma (NTP) catalysis is considered as one of the most promising
technologies to address a wide range of environmental needs, such as volatile organic …

To date, 204 individual molecular species, comprised of 16 different elements, have been
detected in the interstellar and circumstellar medium by astronomical observations. These …

Polycyclic aromatic hydrocarbons (PAHs) have long been invoked in the study of interstellar
and protostellar sources, but the unambiguous identification of any individual PAH has …

We report the detection, for the first time in space, of a new non-functionalised hydrocarbon
cycle in the direction of TMC-1: oC 6 H 4 (ortho-benzyne). We derive a column density for …

To date, 241 individual molecular species, composed of 19 different elements, have been
detected in the interstellar and circumstellar medium by astronomical observations. These …

Much like six-membered rings, five-membered rings are ubiquitous in organic chemistry,
frequently serving as the building blocks for larger molecules, including many of biochemical …
