A Comparative Study on Friction Performance and Mechanical Properties of Printed PETG Materials With Different Patterns

Journal of Applied Polymer Science, EarlyView.
ABSTRACT Investigating the mechanical and wear properties of widely used PETG (polyethylene terephthalate glycol) filaments is important to understanding the material's performance, reliability, and suitability in different application areas. This study performed tensile and wear tests on PETG samples produced with a 3D printer using four infill ...

Unique bone microanatomy reveals ancestry of subterranean specializations in mammals

Evolution Letters, Volume 6, Issue 6, Page 552-561, December 2022., 2022
Abstract Acquiring a subterranean lifestyle entails a substantial shift for many aspects of terrestrial vertebrates’ biology. Although this lifestyle is associated with multiple instances of convergent evolution, the relative success of some subterranean lineages largely remains unexplained.

Effect of Carbon Nanofillers on the Properties of Rubber Composites With High Levels of Carbon Black and Silica

Journal of Applied Polymer Science, EarlyView.
ABSTRACT High‐performance rubber‐based composites often contain significant amounts of fillers such as carbon black and silica. Improving the behavior of such composites with small amounts of nanomaterials remains a challenge, and limited progress has been reported in recent years.

Postcranial anomalies of Eocene freshwater pleurodiran and cryptodiran turtles from the Spanish Duero Basin

The Anatomical Record, EarlyView.
Abstract Testudines are one of the best‐represented taxonomic groups among the Paleogene taxa of the Duero Basin (Castile and Leon Autonomous Community, central Spain). Among them, Neochelys (Podocnemidide) and Allaeochelys (Carettochelyidae) are most abundant, allowing the population to be assessed for osteological anomalies.

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

The Anatomical Record, EarlyView.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...
