Pure PP and PP/MoO3 filaments produced by melt spinning. ABSTRACT Polypropylene (PP) composite fibers containing 0.10, 0.20, and 0.50 wt% molybdenum oxide (MoO3) nanoparticles were produced via melt spinning. In the present study, the effect of this addition on the mechanical, thermal, and chromic properties of the fibers was investigated.

Thermal Stabilization of Chitosan Yarn for Carbon Fiber Production
This study explores chitosan, a biopolymer derived from chitin, as a renewable precursor for carbon fiber production. The authors demonstrate that chitosan fibers can be successfully stabilized under controlled thermal conditions in air and nitrogen.

Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...

Abstract Dicynodonts (Anomodontia: Dicynodontia) were one of the main groups of terrestrial tetrapods in Permian and Triassic faunas. In Brazil, the genus Dinodontosaurus is one of the most common tetrapod taxon in the Triassic Santa Maria Supersequence. This genus has a complex taxonomic history and is represented in the Triassic of both Argentina and
