Acoustofluidics 21: ultrasound-enhanced immunoassays and particle sensors.

Acoustofluidics 2: perturbation theory and ultrasound resonance modes.

In the second part of the thematic tutorial series "Acoustofluidics--exploiting ultrasonic standing waves forces and acoustic streaming in microfluidic systems for cell and particle manipulation", we develop the perturbation theory of the acoustic field in fluids and apply the result in a study of acoustic resonance modes in microfluidic channels.

Acoustofluidics 7: The acoustic radiation force on small particles.

In this paper, Part 7 of the thematic tutorial series "Acoustofluidics-exploiting ultrasonic standing waves, forces and acoustic streaming in microfluidic systems for cell and particle manipulation", we present the theory of the acoustic radiation force; a second-order, time-averaged effect responsible for the acoustophoretic motion of suspended, micrometre-sized particles in an ultrasound field.

Theoretical aspects of microscale acoustofluidics

In this contribution, I summarize some of the recent results within theory and simulation of microscale acoustofluidic systems that I have obtained in collaboration with my students and international colleagues. The main emphasis is on three dynamical effects induced by external ultrasound fields acting on aqueous solutions and particle suspensions: The acoustic radiation force acting on suspen...

Enhanced Removal of Pb+2 from Wastewater Using Combination of Ultrasound and nZVI Methods

This research reported a new method of removal of Pb+2from water by using a nano zero valent iron (nZVI) assisted ultrasonic wave. At first, nZVI was synthesized by an ultrasound assisted method. Particles morphology and surface composition were characterized by FESEM, XRD, and EDX. The XRD patterns showed that the crystallinity of the nZVI prepared using ultrasonic conditions was hi...
