Enhancing Surface Icephobic Performance via Spontaneous Fracture Characteristics of Ice Crystals Regulated by Structural Scale Under Shear Flow Conditions

Advanced Science, EarlyView.
Aerodynamic shear induces spontaneous ice fracture and detachment on hydrophobic surfaces, governed by the interplay between initial ice‐crystal size, growth orientation, and interfacial adhesion. Unexpectedly, microstructural anchoring on superhydrophobic surfaces suppresses ice shedding.

Anatomy and variation in the paraphyletic Mosasaurus lemonnieri assemblage from the Craie phosphatée de ciply, Belgium

The Anatomical Record, EarlyView.
Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...
