Catalysis by a Metastable Photoswitchable Cage

open access: yesAngewandte Chemie International Edition, EarlyView.
A self‐assembled heteroleptic cage is formed by isomerizing a photoswitchable ligand to its metastable Z‐isomeric form (Z‐1) using green light and combining with a non‐switchable ligand (2) and palladium(II) ions. The metastable [Pd2(Z‐1)2(2)2]4+ cage is an out‐of‐equilibrium self‐assembled catalyst, and can be reversibly assembled and disassembled ...

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

open access: yesThe Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.

Vehicles, Pedestrians, and E-bikes: a Three-party Game at Right-turn-on-red Crossroads Revealing the Dual and Irrational Role of E-bikes that Risks Traffic Safety

open access: yes
The widespread use of e-bikes has facilitated short-distance travel yet led to confusion and safety problems in road traffic. This study focuses on the dual characteristics of e-bikes in traffic conflicts: they resemble pedestrians when interacting with ...

Elliptic Fourier analysis as a tool for the taxonomic identification of isolated theropod pedal phalanges

open access: yesThe Anatomical Record, EarlyView.
Abstract Studies of Upper Cretaceous deposits in North America have provided invaluable insights into the continental ecosystems of this time. Theropod (Saurischia, Dinosauria) pedal phalanges are commonplace in these deposits but can be difficult to identify at a finer taxonomic resolution.
