Phosphoramidate and Silyl Amine Mediated Synthesis of Isocyanide Cyclopentadienone Iron Complexes
Carbonyl ligands in cyclopentadienone iron complexes are replaced by isocyanide ligands without using free, malodorous isocyanides. The reaction takes place via an Aza‐Wittig‐type reaction starting from primary amines, employing either phosphoramidates or silyl amines as intermediate reagents.

Thickness Calculation of Pigment Layers and Gold Leaves Using XRF and MA‐XRF Data
ABSTRACT In this work, XRF and MA‐XRF data were used to estimate the thickness of Chromium Oxide (Cr₂O₃) pigment and gold leaf applied over Lead White (2PbCO3.Pb(OH)2). The thickness determination was based on the differential attenuation of the Pb‐Lα and Pb‐Lβ characteristic X‐rays, which allows correlating the overlying material layer with the Pb(Lα ...

Dietary resilience of coral reef fishes to habitat degradation
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

The value of extensive fish ponds as a breeding habitat depends on maintaining the availability of natural marshes as a foraging habitat. This requires reducing impacts from groundwater extraction. Given recent abandonment of aquaculture,
