Isolation and Reactivity of a Square‐Planar Trisamido Silane

open access: yesAngewandte Chemie International Edition, EarlyView.
We report the synthesis and comprehensive characterisation of a square‐planar Si(+IV) hydride supported by an unsymmetric, trianionic and dearomatised N,N,N‐pincer ligand. This system enables element–ligand cooperative reactivity as an alternative to silicon‐centred redox chemistry, illuminating a largely unexplored regime in high‐valent silicon ...

Opium trade and use during the Late Bronze Age: Organic residue analysis of ceramic vessels from the burials of Tel Yehud, Israel

open access: yesArchaeometry, EarlyView., 2022
Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...

The density of discriminants of quintic rings and fields [PDF]

open access: yes, 2010
We determine, asymptotically, the number of quintic fields having bounded discriminant. Specifically, we prove that the asymptotic number of quintic fields having absolute discriminant at most X is a constant times X.

Discrimination of Lipid Hydroperoxide Positional Isomers Using SFC–MS/MS With Sodium Ion: Its Application to Evaluating the Oxidation Mechanisms of Oxidized Oils

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Advanced lipid profiling relies on liquid chromatography–tandem mass spectrometry (LC–MS/MS), but long analysis times remain a challenge. Supercritical fluid chromatography (SFC)–MS/MS using supercritical carbon dioxide offers a faster and more environmentally friendly alternative.

Systematic review and scoring‐based selection of pharmacokinetic models for precision dosing of vancomycin in neonates and children

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
This systematic review identified 112 population pharmacokinetic models of vancomycin in neonates and children. To support rational model selection for model‐informed precision, we developed and applied expert‐driven, transparent criteria that integrate both methodological rigour and clinical relevance.
