Perchloric Acid, an Effective Catalyst for Thermosetting Self‐Crosslinking Hydroxy Acrylic Resins
Journal of Applied Polymer Science, EarlyView.Perchloric acid is an effective catalyst for the crosslinking of hydroxy acrylate resins. Its action is based on the intermediate formation of alkyl perchloric esters. Transesterification gives volatile alkyl perchlorates that evaporate to give a catalyst‐free resin.

Shaping the human face: Periosteal bone modeling across ontogeny
The Anatomical Record, EarlyView.Abstract Facial morphology is a defining aspect of Homo sapiens that distinguishes our species from fossil ancestors and plays a central role in estimating age, sex, and ancestry in both past and present populations. Understanding how the face develops during postnatal ontogeny is essential for interpreting adult facial variation.
