Diffusiophoresis in the presence of a pH gradient
Suin Shim, Janine K. Nunes, Guang Chen +1
Diffusiophoresis is the spontaneous motion of particles under gradients of solutes. In electrolyte-driven diffusiophoresis, the zeta potential of the particles is an important surf…

CO2-driven diffusiophoresis and water cleaning: Similarity solutions for predicting the exclusion zone in a channel flow
Suin Shim, Mrudhula Baskaran, Ethan H. Thai +1
We investigate experimentally and theoretically diffusiophoretic separation of negatively charged particles in a rectangular channel flow, driven by CO2 dissolution from one side-w…

CO-driven diffusiophoresis for removal of bacteria
Suin Shim, Sepideh Khodaparast, Ching-Yao Lai +5
We investigate CO-driven diffusiophoresis of colloidal particles and bacterial cells in a Hele-Shaw geometry. Combining experiments and a model, we understand the characteristi…
