The Highest Oxidation States of the Rare‐Earth Elements and the Challenge of Praseodymium(+5) Compounds

open access: yesAngewandte Chemie International Edition, EarlyView.
Rare Earth Elements are known to form tri‐ and also di‐valent compounds. A few tetra‐valent compounds are also known, and recently the first molecules and crystals with Praseodymium(+5) were synthesized. By defining the atomic Ionization Quotient IQ, Ln(+4) compounds with suitable ligands appear possible for almost all 4f elements, while Pr(+5) may ...

Supercritical CO2 Sorption Within Polymers Used in Medical Devices and Their Packaging

open access: yesJournal of Applied Polymer Science, EarlyView.
In situ CO2 sorption monitoring ensured the establishment of thermodynamic equilibrium in polymers used for medical devices and their packaging. All the studied polymers, except PETG, exhibited similar kinetic profiles, allowing the quantification of CO2 sorption and the resulting polymer swelling under thermodynamic equilibrium conditions. For PETG, a
