A Kinetic Framework for the Pyrolysis of Poly(Ether‐Ketone‐Ketone) (PEKK)

Journal of Applied Polymer Science, EarlyView.
Crosslinking influences poly(ether‐ether‐ketone) (PEKK) pyrolysis. ABSTRACT Research to date on the thermal degradation of poly(ether‐ketone‐ketone) (PEKK) has largely been limited to low temperatures or analysis as part of a composite. Herein, we investigate the pyrolysis kinetics of neat PEKK from 480°C to 1000°C and characterize the degradation by ...

Inline pvT Analysis for Precise Volume Dosing in Injection Molding: Addressing Variability in Recyclate Melts

Journal of Applied Polymer Science, EarlyView.
Precise In‐line volumetric dosing despite varying material composition. ABSTRACT Precise volumetric dosing of polymer melts is essential for dimensional stability and mass consistency in injection‐molded samples, particularly when melt compressibility influences the effective volume delivered to the cavity. Conventional approaches rely on reference pvT

Disparity of turbinal bones in placental mammals

The Anatomical Record, EarlyView.
Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

Bioimaging of sense organs and the central nervous system in extant fishes and reptiles in situ: A review

The Anatomical Record, EarlyView.
Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

The Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...
