Tandon reports on electrokinetic transients on hydrophobic substrates

In a recent paper published in Electrophoresis, Vishal Tandon and co-workers reports on electrokinetic transients on hydrophobic substrates.  Tandon observes that the electrokinetic response of hydrophobic substrates decays with a multi-hour time constant and relates this performance to that on hydrophilic substrates, in which this decay does not occur.  He also observes that these transients can be caused by solvent exchanges and disrupted by electric fields.  Read more about our research at our zeta potential page or about the fundamentals of these processes at Prof. Kirby's textbook page.
