Measuring particle size distribution during the grinding process

A further step toward a stable measurement method for nanoparticles used in industry

26-Jul-2024 - How pharmaceuticals act, how efficient catalysts are and how effective and accurate printing inks function all depend on the size of the nanoparticles they contain. However, there are as of yet no methods for monitoring the particle size distribution during grinding processes. In the EU-funded ...
