| Measurement of Colloidal Forces |
We have developed a new optical technique called Total Internal Reflection Microscopyfor monitoring the instantaneous separation between a Brownian microsphere and the nearby wall. Changes in distance as small as 1 nm can be detected. From the equilibrium distribution of elevations sampled by Brownian motion, we can determine the potential energy profile. Thus we have measured the net bouyant weight of single particles (as small as 0.1 pN), double-layer (electrostatic) repulsion, retarded van der Waals attraction, depletion attraction (arises from nonadsorbing polymer), steric repulsion (arises from adsorbed polymer), the optical force exerted by a focussed laser, and unexpectedly long-range attraction between receptor-ligand pairs. From the dynamics of Brownian motion, we can determine separately the mobility or diffusion coefficient of the sphere, which are greatly reduced by hydrodynamic hinderance afforded by proximity to the wall.

| 2-D assembly of colloidal particles on a/c electrodes |
D/C current normal to a planar electrode causes particles next to the electrode to aggregate as a result electroosmotic flow around the particles; reversing the polarity of the d/c field causes disaggregation. a/c current normal to the electrode can also cause aggregation if the frequency, amplitude and electrolyte are correctly chosen. Aggregation is one step in producing multilayered nanodeposits for photonic devices. Paul Sides and I are using TIRM to observe the motion of single particles NORMAL to an electrode under the same conditions in which others have studied the TANGENTIAL motion of ensembles. A major advantage of using single particles is that any model is axisymmetric; a second advantage is that no other technique is able to make these measurements.

| Determination of Zeta Potential on a Flat Plate Using a Rotating Disc |
In water, a charged particle attracts ions of opposite charge, which accumulate near the surfaces to form a diffuse cloud. The charge on microscopic particles is usually determined by measuring their terminal velocity in an electric field. Determining the charge on a flat surface is more difficult. By rotating a circular disk about its axis, we shear the ion cloud which generates a streaming current. Conservation of charge induces a streaming potential profile in the bulk solution which can be measured and used to deduce the surface charge density. We are working with Malvern Instruments (UK) to develop a commercial device to measure electrical properties of membranes, silicon wafers etc.

| Stability of dispersions caused by nonionic polymers |
Nonionic water-soluble polymers are commercially available and used as dispersants to suspend fine particles in a liquid. For example, Pluronic(R) dispersants sold by BASF are even approved by the FDA for use in drug delivery. We now believe such polymers adsorb on the surface of much larger particles to produce a water-like gel film which acts sterically to prevent the particles from coming close enough together to stick by van der Waals attraction. Heating the solution causes the layer of Pluronic to collapse resulting in loss of stability at some critical temperature. We are now trying to understand why this critical temperature depends substantially on the size of the particle on which it adsorbed. I believe the thickness is a continuous function of temperature; i.e. its collapse is not a 1st order phase transition.
| Stability of dispersions caused by small nonionic surfactants |
Alkane ethoxylates can also stabilize aqueous dispersions although the molecules are much smaller than the Pluronics described above. Is the mechanism the same? At the very least, the adsorbed layer will be thinner. Small-angle light scattering reveals a period of very slow flocculation, whose duration is proportional to the concentration of free surfactant, followed by rapid flocculation. What is happening?
| Electrostatic repulsion between particles in liquids of low dielectric constant |
Electrostatic repulsion across water is quite well understood. A charged particle is surrounded by a cloud of counterions which make it appear electrically neutral from a distance. When two particles are close enough together for their clouds to overlap, repulsion is experienced which decays exponentially with separation (rather than the inverse-square expected from Coulomb's law); the decay length is the Debye length from the Debye-Huckel theory. Electrolytes tend to weakly dissociate in low-dielectric fluids like dodecane. Mechanisms of charging as well as electrostatic forces resulting from charge are much less well understood in nonaqueous media. These are quite important (for example) for display technology in which electric fields are used to turn pixels on and off.

Dennis C. Prieve was born on September 1, 1947 in Portage, Wisconsin and received his BS degree in chemical engineering from the University of Florida in 1970 while working as a co-op student for Westvaco Corp. in N. Charleston, SC. He went on to obtain his MS (1972) and PhD (1974) in chemical engineering from the University of Delaware. His PhD dissertation concerns the kinetics of adsorption of colloidal particles from moving fluids and was performed under the supervision of Prof. Eli Ruckenstein. Since that time he has been on the faculty of the Department of Chemical Engineering at Carnegie Mellon University, where he was promoted to Associate Professor in 1980, to Professor in 1983, and to Gulf Professor in 1997. He spent the 1984-85 year at Princeton Univerity where he collaborated with Prof. William B. Russel on calculating the effect of thin films on the van der Waals interactions. Later he spent the spring semester of 1996 at the University of Melbourne where he collaborated with Dr. Barry Hughes in Mathematics on adhesion and deformation of particles caused by surface forces, and where he also collaborated with Dr. Franz Grieser in Physical Chemistry on measurement of colloidal forces.
