Zeta Potential and Membrane Fouling; Research at Yale

The Deparment of Chemical and Environmental Engineering, Yale University, USA, carries out advanced research into water purification including studies of natural and engineered aquatic systems. After moving to Yale from UCLA two years ago, the deparment’s Llewellyn West Jones, Professor of Environmental Engineering, Menachem Elimelech, needed a more up-to-date machine to continue his research. Both […]

Zooming in on Zeta Potential

The determination of electrophoretic mobility and zeta potential is crucial to understanding the behavior and stability of colloids and suspensions over time. Traditional light scattering methods that are based upon the shifted frequency spectrum are relatively insensitive and can fail when confronted with high viscosity oils, non-polar liquids, high salt concentrations or particles that are […]
