A bothremydid turtle (Pleurodira) from the middle Cenomanian of Vale de Figueira (Belas, Portugal)

open access: yesThe Anatomical Record, EarlyView.
Abstract An unpublished turtle shell from the middle Cenomanian of Vale de Figueira, near Belas (Lisbon District, Portugal), is recognized by us as collected in 1880 under the direction of Carlos Ribeiro. No turtle remains from that region had so far been figured, described or discussed from a systematic point of view.

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

open access: yesThe Anatomical Record, EarlyView.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

Ionic Liquid‐Functionalized Periodic Mesoporous Organosilica: A Robust Support for Palladium Nanoparticles in Carbonylative Suzuki Coupling Reactions

open access: yesChemistry – An Asian Journal, EarlyView.
An ionic liquid‐functionalized periodic mesoporous organosilica (PMO‐IL) is prepared via a sol‐gel method and serves as a support for palladium nanoparticles. The resulting Pd(np)@PMO‐IL catalyst exhibits high activity, selectivity, and recyclability in carbonylative Suzuki coupling reactions under mild conditions, providing an efficient and ...

Molecular Architecture and Single‐Molecule Magnet behavior Control by Playing with Lanthanide Ionic Radii and Bulkiness Ancillary Ligands

open access: yesChemistry – An Asian Journal, EarlyView.
A library of polynuclear complexes involving the ditopic [4’‐(4’’’‐pyridyl‐N‐oxide)‐1,2’:6’1’’‐bis‐(pyrazolyl)pyridine] ligand was designed from the Ln(β‐diketonate)3(H2O)n building blocks. Both ionic radii size of the lanthanide and the bulkiness of the β‐diketonate allowed the control of the final molecular architectures while the second factor ...
