Review on static component generation of ultrasonic waves in solid media
AIP AdvancesIn nonlinear ultrasonics (NLU), in addition to the well-known second harmonic generation (SHG), a static component (SC) generation occurs when a primary ultrasonic wave propagates through a solid with quadratic elastic nonlinearity.

Journal of Food Safety, Volume 46, Issue 4, August 2026.The formation of mono‐, dual‐, and triple‐species biofilms by L. monocytogenes, S. aureus, and E. coli was characterized by cell growth, metabolic activity, staining, and microscopy. Their resistance to a commercial disinfectant (NaOCl) and natural agents such as vinegar and lactic acid was evaluated.

Sensors, 2021 Ultrasonic guided waves are already used for material characterization. The advantage of these waves is that they propagate in the plane of a plate and their propagation characteristics are sensitive to properties of the material.

ChemSusChem, Volume 19, Issue 13, 14 July 2026.This work shows experimentally the possibility of serpentinization (main mechanism of natural hydrogen) at room temperature and ambient pressure, which may provide the rapidly growing hydrogen economy with inspirations to explore new natural hydrogen deposits and new methods for hydrogen production. Natural hydrogen, or “white hydrogen,” is a promising

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Numerical solution of Rayleigh-Lamb frequency equation for real, imaginary and complex wavenumbers
MATEC Web of Conferences, 2018 Guided waves, especially Lamb waves or shear-horizontal waves, are widely used types of waves for ultrasonic inspection of large structures. Well known property of guided waves is their dispersive character, which means that the propagation velocity of ...

Detection of high-order Lamb waves using an end-face injection of ultrasonic pulses
Results in Physics, 2019 In this work, we report the time-of-flight detection of high-order Lamb waves by using an end-face injection of ultrasonic pulses in plates. We used two piezoelectric transducers attached to the opposite edges of a rectangular plate. We applied the Short

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics
Advanced Physics Research, Volume 5, Issue 7, July 2026.This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.
