Measuring nanoparticle concentration and chemistry
Nanoparticles are increasingly used in innovative products manufactured by advanced industries and provide enhanced, unique properties of great commercial and societal value. The demand for high performance materials places increasingly stringent tolerances on the properties of nanoparticles. The major unmet metrological needs in the production of high quality nanomaterials are the measurement of particles’ concentration surface chemistry. These measurements are critical to the performance of novel materials in products. To underpin trade and the supply chain for these novel materials, this project focused on the development of reference materials, compared the performance of different techniques, initiated prenormalisation studies and provided input to internationally accepted standards.
