Angewandte Chemie, EarlyView.A series of oxoiron(IV) complexes was synthesized to determine the impact of electronically tuned aromatic substitution in the secondary sphere of the ligand. Despite possessing identical electronic properties, they show significant differences in C─H oxidation reactions.

Methane Activation by B5+ Toward a CB5H2+ Isomer Containing a Planar Tetracoordinate Carbon Atom
Angewandte Chemie, EarlyView.Methane activation by B5+ yields CB5H2+ through H2 elimination. Electronic‐structure calculations connect the nascent dehydrogenation product to a low‐lying isomer containing a planar tetracoordinate carbon atom. ABSTRACT Planar tetracoordinate carbon (ptC) motifs have been identified predominantly in the global‐minimum structures of gas‐phase clusters

BJS (British Journal of Surgery), EarlyView., 2020 All patients operated for oesophageal cancer in Sweden from 2013 to April 2018 were identified, and 246 patients were recruited to this population‐based nationwide Swedish study. The results show that longitudinal health‐related quality of life after minimally invasive oesophagectomy was similar to that of the open surgical approach.

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT This study presents the first experimental liquid–liquid equilibrium (LLE) data for quaternary systems composed of refined olive pomace oil, oleic acid, ethanol, and water at 303.15 K. These data are essential for the design and optimization of solvent‐based deacidification processes, particularly for oils with high free fatty acid (FFA ...

Journal of Applied Polymer Science, EarlyView.The effects of carboxymethyl chitosan and genipin on zein‐based biodegradable materials have been investigated. The addition of these compounds alters the material's structure, water absorption, and thermomechanical behavior, while genipin enhances mechanical performance through the formation of polymer networks.

The Anatomical Record, EarlyView.Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients
The Anatomical Record, EarlyView.Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II
The Anatomical Record, EarlyView.Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.
