Topology‐Dependent Coke Formation in the Catalytic Pyrolysis of Phenol Over HFAU and HZSM‐5 Zeolites

Angewandte Chemie, EarlyView.
The coke formation and speciation during the catalytic pyrolysis of lignin over different zeolite topologies were studied with a combination of operando EPR spectroscopy and ex situ pulsed techniques aided with DFT calculations. Operando EPR data showed that the coke formation in HFAU is fast compared to HZSM‐5.

Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

American Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024

Australian Journal of Social Issues, EarlyView.
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

Photocatalytic Transfer Hydrogenation Using Plastic Hydrolysates as Hydrogen Donor

Angewandte Chemie, EarlyView.
Plastic waste is transformed into functional amines via solar‐driven transfer hydrogenation. Soluble monomers from acid hydrolysis of waste polymers serve as a hydrogen (electron/proton)donors in the selective reduction of nitroarenes using a visible light active photocatalyst consisting of cobalt promoted molybdenum disulfide integrated in cyanamide ...

Spatial Detection of Microsphere Polystyrene Plastics and Molecular Remodeling within a Full‐Body Mouse with MALDI Trapped Ion Mobility Mass Spectrometry Imaging

Angewandte Chemie, EarlyView.
Orally administered polystyrene microplastics accumulate in murine tissues and are detected using MALDI‐MSI with TIMS. Lipid profiling reveals decreases in hexosylceramides, sphingomyelins, and ether‐linked phospholipids, indicating altered metabolism.

Room‐Temperature Gas‐Phase CO2‐to‐C3 Coupling by a 4f‐Aromatic Cluster

Angewandte Chemie, EarlyView.
We engineered a 4f metalla aromatic cluster, PrB2C2−, that enables efficient sequential C−C coupling with CO2 at room temperature, yielding a linear C3 backbone. This system provides a complete theoretical catalytic cycle and establishes a new design principle for lanthanide mediated CO2 activation.
