Enhanced Dielectric Constant by Al Gradient Doping on Atomic‐Layer‐Deposited HfO2‐Based Metal–Insulator–Metal Capacitor

open access: yesAdvanced Electronic Materials, EarlyView.
This study demonstrates that Al gradient doping significantly enhances the dielectric performance of HfO2‐based MIM capacitors compared to standard uniform Al doping. By more effectively promoting the tetragonal high‐k phase, it increases capacitance, reduces leakage current, and achieves a record‐high dielectric constant, validated across various ...

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

open access: yesThe Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...
