TL;DR: Investigation of oxidation and friction for two MoS2 films with distinctively different microstructures-amorphous and planar/highly-ordered- before and after exposure to atomic oxygen (AO) and high-temperature (250 °C) molecular oxygen shows comparable oxidation of both coatings via AO; however, monolayer resolved compositional depth profiles from HS-LEIS reveal that the microstructure of the ordered coatings limits oxidation to the first atomic layer.

TL;DR: The role of water in the tribochemical mechanisms of ultralow wear polytetrafluoroethylene (PTFE) composites was investigated by studying 10 and 20 wt % polyether ether ketone (PEEK)-filled and 5 wt....

TL;DR: Triceratops developed complex dental morphology, allowing it to become a dominant herbivore in the late Mesozoic era, and similar discoveries in hadrosaurids (duck-billed dinosaurs), suggest that tissue-mediated changes in dental morphology may have played a major role in the remarkable ecological diversification of these clades and perhaps other dinosaurian clades capable of mastication.

TL;DR: This research team composed of paleontologists, evolutionary biologists, and engineers have developed a protocol to determine the histological make-up of grinding dentitions in extant and fossil taxa and analyze those data in phylogenetic contexts to infer evolutionary patterns as they relate to feeding.

TL;DR: In this article, Teflon® PFA 340 samples with various weight fractions of α-alumina (0, 5, 7.5%, 10%) were injection molded, and samples from each mold were wear tested against stainless steel.
