Influence of ultrasonic irradiation on the microstructure of Cu/Al2O3, CeO2 nanocomposite thin films during electrocodeposition

TL;DR: In this paper, the effects of ultrasonic irradiation on agglomeration during electrocodeposition of Cu-Al2O3 and Cu-CeO2 nanocomposite thin films on a silicon substrate are investigated.
Journal ArticleDOI

Plastic deformation in nanoscale gold single crystals and open-celled nanoporous gold*

TL;DR: The results of two sets of experiments to measure the elastic?plastic behavior of gold at the nanometre length scale are reported in this article, and the results of detailed finite element analyses of the specimen suggest that the critical resolved shear stress of the gold single crystal was as high as 135?MPa which would lead to a maximum uniaxial stress of about 500?MPa after several per cent strain.
Journal ArticleDOI

Microperforations significantly enhance diffusion across round window membrane.

TL;DR: Diffusion cells can be applied to the study of RWM permeability in vitro and microperforation in RWM is an effective means of increasing diffusion across the RWM.
Journal ArticleDOI

Energy dissipation mechanisms in ductile fracture

TL;DR: In this article, a dimensional analysis is performed to identify the sets of dimensionless parameters which contribute to energy dissipation via dislocation-mediated plastic deformation at a crack tip.
Journal ArticleDOI

Novel 3D-printed hollow microneedles facilitate safe, reliable, and informative sampling of perilymph from guinea pigs

TL;DR: Hollow microneedles can facilitate aspiration of perilymph across the RWM at a quality and volume adequate for proteomic analysis without causing permanent anatomic or physiologic dysfunction.
