Angewandte Chemie, EarlyView.Kaitocephalin (KCP) is a neuroprotective fungal metabolite with a unique scaffold of amino acids linked via C–C bonds. Genome‐transcriptome analyses identified its biosynthetic gene cluster (kpb cluster) in Eupenicillium shearii. LC‐MS/MS profiling identified four new KCP‐related compounds.

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Angewandte Chemie, EarlyView.Unusually low metal–ligand bond orders are observed in high spin iron(II) pnictogenidene (PH2– and AsH2–) complexes. Electronic structure analysis provides evidence for multiconfigurational character that attenuates the metal–ligand multiple bond character normally that is typically associated with pnictogenidene ligands. These complexes can be used to

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

FORM OR FUNCTION? TOWARDS A TYPOLOGY OF AUGUSTAN CITY WALLS IN ROMAN ITALY
Journal of Ancient History and Archaeology, 2017 During the Augustan period, some 18 cities in Roman Italy constructed city walls around their urban centres – the last cluster of city walls to be built here until the late third century AD.

Advanced Engineering Materials, EarlyView.This study investigates laser‐based oxide removal of Cu inserts in oxygen‐free conditions and examines long‐term oxidation kinetics and surface chemistry under different atmospheres via X‐ray photoelectron spectroscopy. Al–Cu compound casting with differently oxidized surfaces is performed, and intermetallic phase formation, morphology, and thermal ...

Versailles and Dresden: Myths and Models
Bulletin du Centre de Recherche du Château de Versailles, 2023 Notwithstanding some pioneering exhibitions and publications in recent years, art historians who study the reigns of Augustus the Strong and Augustus III typically focus their attention on the electoral court in Dresden, with little consideration of the ...

Advanced Materials Technologies, EarlyView.Liquid metal direct writing is advanced from a technological and fundamental point. Utilizing a kinematic bed, printing on large surfaces with irregularities is enabled. Furthermore, a pressure‐driven flow during printing is discovered that affects the thickness of traces.
