Pipe fouling is a challenging problem in many industrial applications. Current cleaning techniques require halting the production during the cleaning phase and the existing methods are unable to do targeted cleaning, even though fouling is often loca

Due to their high content of unsaturated fatty acids and controllable mechanical properties, oleogels show promise as a replacement for traditional fats in food products. Controlling the oleogel formation with ultrasound makes it possible to tune the

We present a simulation model that can be used to study the movement of an object in an acoustic levitator. The model uses the boundary element method (BEM) to compute the levitator's acoustic field, and the finite element method (FEM) to compute the

Ultrasound provides a way to clean fouled pipes in industrial settings without interrupting the production. Ultrasonic clamp-on cleaners are used to clean pipes, but they typically cannot focus the cleaning power. This leads to insufficient cleaning

Oleogels are lipid-based soft materials composed of large fractions of oil (> 85%) developed as saturated and hydrogenated fat substitutes to reduce cardiovascular diseases caused by obesity. Promising oleogels are unstable during storage, and to imp

In acoustic microscopy, a focused high frequency ultrasonic pulse is used to nondestructively image samples. The ultrasound signal is focused with an acoustic lens. In case of a broadband signal, the final image can feature aberrations, caused by fre

Time-reversal (TR) is method to focus acoustic energy inside complex media. TR focusing to a predefined target point requires either an echo from a target point with acoustic impedance contrast or direct impulse actuation at the target point. Here, w
