N‐Heterocyclic Carbenes on a III‐V Semiconductor: From Chain Formation to Ordered Monolayers

open access: yesAngewandte Chemie International Edition, EarlyView.
The functionalization of GaAs, a model III‐V semiconductor, with N‐heterocyclic carbenes is demonstrated in a multidisciplinary experimental and theoretical approach. In this way, ordered monolayers consisting of chains of molecules binding covalently to the surface are obtained, which are found to strongly modify the surface properties as evident from

Conceptualising quality early childhood education: Learning from young children in Brazil and South Africa through creative and play‐based methods

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Early childhood has increasingly been acknowledged as a vital time for all children. Inclusive and quality education is part of the United Nations Sustainable Development Goals, with the further specification that all children have access to quality pre‐primary education.

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
