The propagation of interface acoustic waves (IAWs) in 128° YX-LiNbO3/SU-8/overcoat structures was theoretically studied and experimentally investigated for different types overcoat materials thicknesses the SU-8 adhesive layer. Three-dimensional finite element method analysis performed using Comsol Multiphysics software to design an optimized multilayer configuration able achieve efficient guiding effect IAW at LiNbO3/overcoat interface. Numerical results showed following: (i) faster than...
Lysine-covalently modified graphene oxide (GO-Lys) was prepared by an innovative procedure. Lysine brushes promote enhanced adsorption of bisphenol A, benzophenone-4 and carbamazepine contaminants from tap water, with a removal capacity beyond the state art.
The need of cheap and easy to use biosensors for rapid diagnostics is a crucial challenge in medicine: indeed, devices must offer multiple properties such as fast response, high sensitivity, reduced sample processing, etc. In this respect, optical remain promising class biodevices. Here we present an extensive investigation the surface silver-coated zinc oxide disordered nanostructures efficient biosensing platform detect complex organic profiles via Raman spectroscopy. particular, combine...
Piezoelectric c-axis oriented zinc oxide (ZnO) thin films, from 1.8 up to 6.6 µm thick, have been grown by the radio frequency magnetron sputtering technique onto fused silica substrates. A delay line consisting of two interdigital transducers (IDTs) with wavelength λ = 80 was photolithographically implemented surface ZnO layers. Due IDTs’ split-finger configuration and metallization ratio (0.5), propagation fundamental, third, ninth harmonic Rayleigh waves is excited; also, three leaky...
