Interface Acoustic Waves in 128° YX-LiNbO/SU-8/Overcoat Structures.
Micromachines (Basel)
January 2025
Department of Astronautical, Electrical and Energy Engineering, University of Rome "La Sapienza", Via Eudossiana 18, 00184 Rome, Italy.
The propagation of interface acoustic waves (IAWs) in 128° YX-LiNbO/SU-8/overcoat structures was theoretically studied and experimentally investigated for different types of overcoat materials and thicknesses of the SU-8 adhesive layer. Three-dimensional finite element method analysis was performed using Comsol Multiphysics software to design an optimized multilayer configuration able to achieve an efficient guiding effect of the IAW at the LiNbO/overcoat interface. Numerical analysis results showed the following: (i) an overcoat faster than the piezoelectric half-space ensures that the wave propagation is confined mainly close to the surface of the LiNbO, although with minimal scattering in the overcoat; (ii) the presence of the SU-8, in addition to performing the essential function of an adhesive layer, can also promote the trapping of the acoustic energy toward the surface of the piezoelectric substrate; and (iii) the electromechanical coupling efficiency of the IAW is very close to that of the surface acoustic wave (SAW) along the bare LiNbO half-space.

Iuav University of Venice, Italy. Electronic address:
Coastal lagoon habitats provide multiple ecosystem goods and services that contribute to people's well-being. However, owing to degradation from both anthropogenic and natural causes, these areas require conservation and protection that involve considerable public investment. To help determine this investment, this study estimates the nonmarket economic value of habitat, regulation, and cultural ecosystem services (ESs) using people's environmental attitudes and temporal preferences.

January 2025
Department of Civil Engineering, National Institute of Technology, Mizoram, India.
Chronic exposure to traffic noise is associated with increased stress and sleep disruptions. Research on the health consequences of environmental noise, specifically traffic noise, has primarily been conducted in high-income countries (HICs), which have guided the development of noise regulations. The relevance of these findings to policy frameworks in low- and middle-income countries (LMICs) remains uncertain.

Biosensors (Basel)
December 2024
School of Electrical and Automation Engineering, East China Jiaotong University, Nanchang 330013, China.
Soft wireless passive sensors have been applied in biological, engineering, and other fields due to their advantages in powerless supply and remote data transmission. External information is obtained by soft wireless passive sensors via the external coils based on electromagnetic induction. The purpose of this review paper is to outline the biological applications of soft wireless passive chipless sensors and provide a classification of wireless passive sensors and an overall explanation of the main work.

School of Nursing, Midwifery & Social Sciences, CQUniversity, Brisbane, Australia.
Background: Transitioning into the first year of clinical practice as a nurse or changing specialties in the nursing career presents a critical phase for novice nurses characterized by excitement, apprehension, and the phenomenon of "transition shock." Within perioperative nursing, this transition phase takes on distinctive challenges. However, there is a lack of empirical evidence on transition programs and arrangements.
