Chemical and genetic characterization of the ungrouped pallasite Lieksa
Meteoritics &Planetary Science, Volume 58, Issue 12, Page 1747-1759, December 2023., 2023 ABSTRACT The meteorite Lieksa was found in 2017 in Löpönvaara, Finland, and later donated to the Finnish Museum of Natural History. Here, we report siderophile element concentrations, genetic isotopic data, and a metal–silicate segregation age for the meteorite.

SiO Emission from the Orion Nebula [PDF]
Symposium - International Astronomical Union, 1980 SiO emission in both a strong maser transition in the first excited vibrational state and in a weaker transition in the ground vibrational state both arise from the same small region in the Kleinmann-Low Nebula in Orion. Within the errors, the source position coincides with that of the infrared source IRc2.

A New Look at the Molecular Gas in M42 and M43: Possible Evidence for Cloud–Cloud Collision that Triggered Formation of the OB Stars in the Orion Nebula Cluster [PDF]
Astrophysical Journal, 2017 The Orion Nebula Cluster toward the H ii region M42 is the most outstanding young cluster at the smallest distance (410 pc) among the rich high-mass stellar clusters.

Photoelectron Photoion Coincidence Spectroscopy of Biradicals
ChemPhysChem, Volume 24, Issue 16, August 15, 2023., 2023 Biradical species are notoriously difficult to detect, due to their open‐shell character and the resulting high reactivity. As reactive intermediates, they are found in flames, in the interstellar medium, and in earths’ atmosphere. Unveiling their electronic structure is of paramount interest to understand their chemistry.

ChemPlusChem, Volume 88, Issue 5, May 2023., 2023 A metal worker's laboratory: from Georg Agricola, De re Metallica, Libri XII, Basel, 1556, illustrating a reverberatory oven similar to what Carl Wenzel would have used to divide his metals in the 1770s. This Perspective essay discusses Wenzel, who was a chemist and an alchemist with deep knowledge of acids, bases and salts, and he was credited with ...

Cloud fragmentation and proplyd-like features in HII regions imaged by HST [PDF]
, 2006 We have analyzed HST ACS and WFPC2 new and archival images of eight HII regions to look for new proto-planetary disks (proplyds) similar to those found in the Orion Nebula.

Hunting for Runaways from the Orion Nebula Cluster [PDF]
Astrophysical Journal, 2020 We use Gaia DR2 to hunt for runaway stars from the Orion Nebula Cluster (ONC). We search a region extending 45° around the ONC and out to 1 kpc to find sources that have overlapped in angular position with the cluster in the last ∼10 Myr. We find ∼17,000

Review of European, Comparative &International Environmental Law, Volume 32, Issue 1, Page 105-118, April 2023., 2023 Abstract This article compares the framework of environmental public interest litigation in China to the individualized system of judicial review in Germany. It shows that environmental reform requires modern States such as Germany and China to consider certain objective criteria related to the public interest.
