Using Zeta Potential to Optimize the Water Clarification Process in a Full-Scale Water Production Facility

Nobbmann U., Gertig K.R., Billica J.A., Morfesis A., Malvern Instruments, Inc., US

Zeta potential provides a measurable value to monitor optimal water clarification capabilities. The magnitude of the zeta potential value indicates the repulsive interaction between particles; a zero zeta potential means that the conditions for the [...]

Particle Characterization of Nanoscale Materials using Dynamic and Static Light Scattering

Bumiller M., DeLuca T., Mattison K., Rawle A., Malvern Instruments, Inc., US

Purpose: Novel materials with single particle dimensions at the nano scale are submitted to our laboratory on a regular basis. These samples include single walled nanotubes (SWNT), buckyballs, quantum dots and various metal oxides. Determining [...]

Physicochemical Characterization of Nanosize Zinc Oxide and Titanium Dioxide used as UVR Sunscreen Agents in Cosmetic Formulations

Morfesis A., Fairhurst D., Malvern Instruments, Inc., US

The physical (particulate) sunscreen agents, ZnO and TiO2, are increasingly used to provide UV protection in a wide variety of cosmetic and personal care products. The particle size distribution (PSD) of the ZnO and TiO2 [...]
