In this work it is introduced a new approach to calculate the density of liquids in terms of the energies of the acoustic signals. This method is compared to other methods in the time domain (peak-to-peak amplitudes) and ...

This paper presents grinding results obtained with a Chilean porphyry copper ore in the ultrasonic nip roll grinder of the US Comminution Center. Comparison with ball milling is performed by scaling-down industrial ball ...

A fast and accurate method for the extraction of Ca, Mg, Mn and Zn from vegetables is proposed. Ultrasonic energy and dilute acid are used for the extraction. Optimisation conditions for the ultrasonic bath were established: ...
