On the Post‐Curing Thermal Treatment of Silicone Rubbers: A Study on Electrical Performance

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Silicone rubbers, particularly poly(dimethylsiloxane) (PDMS), are popular across various industrial applications; however, notable issues arise from volatile cyclic siloxanes and their tendency to compromise performance. This study investigates the electrical performance (DC conductivity, dielectric spectroscopy, DC breakdown) of two ...

Advancing the Growth of GaN on AlScN and AlYN by Metal–Organic Chemical Vapor Deposition

open access: yesAdvanced Physics Research, EarlyView.
Growth of 2D GaN caps on AlScN and AlYN layers by metal‐organic chemical vapor deposition is challenging due to low GaN adatom mobility on these layers. Detailed structural analysis and growth parameter variation reveal how such layers can be grown.

Comparing cranial biomechanics between Barbourofelis fricki and Smilodon fatalis: Is there a universal killing‐bite among saber‐toothed predators?

open access: yesThe Anatomical Record, EarlyView.
Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐
