| Description | A new method for the characterisation of particles suspended in fluids has been developed based on measuring the angular dependence of the scattering of sound. The technique can measure small amounts of material (~ millitres) and has the potential to be used in-line and at-line in material processing operations. |
| Exploitation Route | We have published preliminary results on the angular scattering method and are building a new version of the device based on the learnings from the first device. |

| Description | The project findings are contributing to industrial applications of ultrasound in the characterisation of powders and crystallising systems. It is also now contributing to an IUK industrial project jointly with Diamond Labs (COMPETITION A4I, Phase Change Control by Very Low Power Ultrasound , Project No: 103741, ) with potential extensive impact throughout industries using crystallisation processes (see papers associated with this submission). The project outputs supported PhD student work collaboration with the Department of Physics in the University of Southern Denmark, jointly supported by Arla Foods and with Nestle, involving significant beam time at Diamond Labs (SM20481, MT21081,MG23324, SM25788, SM27656) |
