Diagnostic concordance of dermatopathology and PCR in differentiating eczema from psoriasis

open access: yesJournal of the European Academy of Dermatology and Venereology, Volume 40, Issue 7, Page 1227-1237, July 2026.
Distinguishing psoriasis from eczema is challenging due to overlapping clinical and histological features. This study shows substantial inter‐observer variability among dermatopathologists and demonstrates that a NOS2‐/CCL27‐based molecular test, including a fully automated platform, provides more accurate and reproducible diagnoses, particularly in ...

Copper Complexes with Arylated Triethylenetetramine Ligands: Reactivity Toward Dioxygen and Peroxides

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
Here, we describe new Cu(I)/Cu(II) complexes based on arylated tren ligands and investigate their reactivity toward O2 and peroxides. Low‐temperature–stopped flow studies revealed the formation of transient copper–oxygen species, including superoxido, hydroperoxido, and alkylperoxido intermediates.

Dehydrogenative Coupling of Hydrosilanes With Alcohols and Amines: A Concerted Asynchronous Mechanism With an Early Hidden Reaction Intermediate

open access: yesInternational Journal of Quantum Chemistry, Volume 126, Issue 12, June 15, 2026.
DFT reveals a concerted asynchronous mechanism with a hidden reaction intermediate in hydrosilane coupling (HRI), which occurs prior to a pentacoordinated silicon transition state. This mechanism indicates that the concerted asynchronous SiO bond formation and SiH bond cleavage precede the HH bond formation.

Scaffold Dependent Coordination Modes of Chelating PEP‐Type Ligands in Iron(0) Carbonyl Complexes (E = O, S)

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.
The reaction of iron pentacarbonyl with various chelating diphosphine ligands containing oxygen or sulfur atoms in their backbone yields complexes that exhibit noteworthy coordination behavior. Depending on the natural bite angle of the ligands and the coordination behavior of the heteroatom, preferences regarding the coordination geometry are verified
