Oxidation of Intermetallic Al–Fe–Mo Phases

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The oxidation of ternary intermetallic phases reveals the initial selective oxidation to Al2O3 and a phase segregation into AlMo3 and AlFe. Fe‐rich molybdates result from an intermediate metallothermic redox reaction involving AlFe. Thermal oxidation processes of Al9‐xFexMo3 intermetallic phases are investigated by thermogravimetry, in situ X‐ray ...

Spin Crossover around Room Temperature: Effects of Remote Ligand Symmetry Breaking within Jäger‐Type Iron(II) Complexes

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Remote symmetry breaking in Jäger‐type iron(II) complexes shifts stepwise spin crossover (SCO) profiles to continuous profiles with transition temperatures around room temperature. In a bottom‐up approach, we studied the feedback of slight molecular modifications on the spin crossover (SCO) properties of otherwise structurally conserved iron(II ...

The Appreciation Game. A Monist Ontology of Works of Art

open access: yesEuropean Journal of Philosophy, EarlyView.
Abstract A pluralist ontology of art states that works of art can belong to distinct ontological categories whereas a monist ontology states that all works of art belong to one ontological category. A monist ontology would be preferable since it is more informative about the nature of art, and may pave the way for a definition of art.

Anemia‐associated mutations disrupt the CDIN1‐Codanin1 complex in inherited congenital dyserythropoietic anemia I (CDA‐I) disease

open access: yesThe FEBS Journal, EarlyView.
Congenital dyserythropoietic anemia type I (CDA‐I) arises from mutations in Codanin1 and CDIN1. Using quantitative biophysical approaches, we show that disease‐associated mutations disrupt the CDIN1‐Codanin1 complex. Our findings provide critical insights into the molecular mechanism that links protein dysfunction to disturbing chromatin arrangement ...
