Impact of Rapid Thermal Annealing on the Structural and Piezoelectric Properties of AlN Thin Films
Aluminum nitride (AlN) is a biocompatible piezoelectric material suitable for energy harvesting in MEMS resonators. Through rapid thermal annealing, a threshold for CMOS‐compatible processes is established. AlN improved its crystallinity and enhanced the piezoelectric coefficient by ∼160%. Devices show an improvement in the electromechanical properties

ABSTRACT Purpose To integrate MR‐based servo navigation in MPRAGE and 3D‐TSE sequences and demonstrate its potential for prospective head motion correction in structural imaging. Methods Repeated modules of servo navigators were inserted before each preparation pulse of MPRAGE and 3D‐TSE sequences (before‐prep) for rapid convergence of motion parameter

Spent coffee grounds were valorized as a sustainable template for the solvent‐free synthesis of Ce‐loaded TiO2 photocatalysts, promoting enhanced Ce–Ti interactions and tailored morphology. The resulting materials were successfully applied in photocatalytic hydrogen production via ethanol photoreforming, gas‐phase 2‐propanol oxidation, and aqueous 5 ...

Ultrathin Freestanding BiFeO3 Membranes Grown by Pulsed Laser Deposition
Ultrathin freestanding BiFeO3 membranes down to five‐unit cells are realized by pulsed laser deposition using a water‐soluble Sr3Al2O6 sacrificial layer. Strontium diffusion is revealed to drive the spontaneous formation of an Aurivillius‐like phase, while ultrathin SrRuO3 interlayers suppress interfacial intermixing, preserve polar tetragonality, and ...

ABSTRACT Background Although standardized, evidence‐based diagnostic tools are essential for the assessment of the efficacy of facial skin rejuvenation, aesthetic medicine has largely relied on subjective evaluations, especially in primary clinics. Recent studies have demonstrated the potential of skin biophysical properties for objective assessment ...

Moiré patterns in 2D materials
The relative orientation between two or more layers of a 2D crystal can create moiré patterns. The patterns have a characteristic size, known as the moiré length, which can be directly controlled by the twist angle between layers.
