Interfacial Phonon Scattering and Transmission Loss in >1 um Thick Silicon-on-insulator Thin Films

, 2018
Scattering of phonons at boundaries of a crystal (grains, surfaces, or solid/solid interfaces) is characterized by the phonon wavelength, the angle of incidence, and the interface roughness, as historically evaluated using a specularity parameter p ...

Amorphous Hydrogenated Silicon Carbide Interlayers: Chemical, Optical, and Tribological Behavior for Improving Adhesion of Carbon‐Based Films to Ferrous Alloy

Surface and Interface Analysis, EarlyView.
ABSTRACT Diamond‐like carbon thin films have been gaining attention in the last years due to their unique properties, such as low friction coefficient and high wear resistance. However, the lack of adhesion between DLC coatings and ferrous alloys complicates their wider industrial application.

Investigation of the skin recovery dynamics following acute sleep deprivation and the correlations among biological parameters

Sleep Research, EarlyView.
Abstract Background Sleep deprivation leads to changes in circadian rhythm, causing skin problems and aging. Whether acute sleep deprivation can be normalized after 14 days of natural skin metabolism is an important indicator for guiding treatment of sleep‐related skin physiological changes and mechanisms.

Polarization vision and the physiological basis for trichromatic vision in Philaenus spumarius: Understanding host‐seeking behaviour in insect vectors for Xylella fastidiosa control

Annals of Applied Biology, EarlyView.
We investigated the role of vision in host‐seeking behaviour by Philaenus spumarius, the main European vector of Xylella fastidiosa, through an integrated anatomical, optical, physiological, and behavioural study. Our data highlight that the spittlebug uses visual cues, including polarized light, which may aid in detecting the polarized reflections ...

Probing an Ultracold-Atom Crystal with Matter Waves

, 2012
Atomic quantum gases in optical lattices serve as a versatile testbed for important concepts of modern condensed-matter physics. The availability of methods to characterize strongly correlated phases is crucial for the study of these systems. Diffraction

Reconstruction of deep and perforating corneal defects in dogs—A review (Part II/III): Biomaterials and keratoprosthesis

Veterinary Ophthalmology, Volume 28, Issue 2, Page 532-542, March 2025.
Abstract The surgical reconstruction of severe corneal ulcers is a common and crucial component of the clinical practice of veterinary ophthalmology. Numerous surgical techniques are used in dogs for corneal reconstruction, and these techniques may be categorized by the material used to repair the corneal lesion.
