Triplett‐Metallovinylidene von Palladium und Platin auf Basis eines chelatisierenden P/Diazoalkens

Angewandte Chemie, EarlyView.
Es wird eine neue Klasse an chelatisierenden Diazoalkenen vorgestellt und ihre Koordinationskomplexe mit Pd und Pt charakterisiert. Durch Bestrahlung wird ein N2‐Verlust erzeugt, wodurch erstmals spektroskopisch charakterisierte Triplet‐Metallovinylidene unter Verwendung von FD‐FT‐THz‐EPR‐Spektroskopie und SQUID‐Messungen nachgewiesen werden.

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

Applications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.

Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils

The Anatomical Record, EarlyView.
Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

Organochlorine Pesticides in Karst Soil: Levels, Distribution, and Source Diagnosis

International Journal of Environmental Research and Public Health, 2021
Excessive reclamation and improper use of agrochemicals in karst areas leads to serious non-point source pollution, which is of great concern and needs to be controlled, since contaminants can easily pollute groundwater due to the thin patchy soil and ...

Late Pleistocene to Holocene sedimentation in the Great Blue Hole (Lighthouse Reef, Belize): Results from a 30 m long core

The Depositional Record, EarlyView.
A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes
