In this Commentary, we discuss the paper Quantitative Determination of Size and Shape of Surface-Bound DNA Using an Acoustic Wave Sensor [Tsortos et al., Biophys. J. 94(7), 2706-2715 (2008)]. The paper under discussion presents a novel theory that uses the response of a Shear-Horizontal Surface Acoustic Wave device to characterize surface-attached double- and triple-strand DNA. The authors rela...

In a travelling wave thermoacoustic device, the regenerator sandwiched between a pair of (hot and cold) heat exchangers constitutes the so-called thermoacoustic core, where the thermoacoustic energy conversion from heat to acoustic power takes place. The temperature gradient along the regenerator caused by the two heat exchangers excites and maintains the acoustic wave in the resonator. The dev...

Acoustic standing wave technology combined with microtechnology opens up new areas for the development of advanced particle and cell separating microfluidic systems. This tutorial review outlines the fundamental work performed on continuous flow acoustic standing wave separation of particles in macro scale systems. The transition to the microchip format is further surveyed, where both fabricati...

We present research on the excitation of ocean surface wind waves in non-homogeneous situations, for case a deep water strait presence constant wind, blowing perpendicular to coast line. The statistical wave model used is based Hasselmann equation with high-wavenumbers wave-breaking dissipation, exact non-linear four-wave interaction, and ZRP (Zakharov-Resio-Pushkarev (Zakharov et al. Nonlin Pr...

Weak measurement [1,19] combined with quantum delayed-choice experiment that use quantum beam splitter instead of the beam splitter give rise to a surprising amplification effect, i.e., counterintuitive negative amplification effect. We show that this effect is caused by the wave and particle behaviours of the system to be and can’t be explained by a semiclassical wave theory, due to the entang...

In the field of industrial structure detection, acoustic signals have been pivotal. A cost-effective and highly sensitive monitoring system that can enhance weak has always an interesting topic in many research fields. However, environmental noise consistently hindered improvement signal-to-noise ratio (SNR) traditional systems. this work, we propose a (PC-Mie) couples phononic crystal (PC) poi...

Introduction: Microbubbles are widely used as contrast agent in diagnostic ultrasound. Recently they have shown good potential for applications in the therapeutic field such as drug delivery to the brain. Recent studies have shown focused ultrasound in conjunction with injected micro-bubbles could temporarily disrupt blood-brain barrier and let therapeutic agents transport into...

Within a time span of 15 years, acoustic metamaterials have emerged from academic curiosity to become an active field driven by scientific discoveries and diverse application potentials. This review traces the development of acoustic metamaterials from the initial findings of mass density and bulk modulus frequency dispersions in locally resonant structures to the diverse functionalities afford...

We experimentally investigate the acoustic characteristic of micro plasma shock wave obtained by femtosecond laser ablation of silicon wafer surface using F-P optical fiber acoustic sensor with anti electromagnetic interference. The experimental results show that each of the femtosecond laser pulse can only produce a plasma shock wave. Under the different femtosecond laser energy, the acoustic ...
