Transport Phenomena

Concentration Visualization of a Viscoelastic Surfactant Solution in a Silicon and Glass Micromodel

Transport of momentum, mass and heat plays an important role in a variety of biological, technological and natural processes. The interplay of transport with other physical and chemical processes leads to fascinating structures on a wide range of scales in contexts such as morphogenesis, synthesis of nanoparticles, formation of nano- and micro- scale structures, aging and damage of porous structures, and single/multiphase flows. Within our department, a number of pioneering experimental, theoretical and computational research projects, exploring and exploiting transport processes, are underway:

  • Experimental and quantitative modeling studies on the role of morphogen gradients on pattern formation in development, using the dorsoventral patterning of follicular epithelium in the developing rosophila eggs as a model system. (Shvartsman)
  • Experimental and modeling studies on the processing of colloidal dispersions and thin polymer films, which are central to a vast array of important technologies ranging from the formation of impermeable coatings from latex dispersions to fabrication of photonic crystals, with special focus on the fascinating interplay of surface tension, electric fields, interparticle forces, elastic and viscous stresses that can be exploited to create parallel cracks in directional drying, periodic arrays of pillars in thin polymer films between silicon wafers, and delayed, but abrupt, collapse of colloidal gels. (Russel)
  • Experimental and modeling studies on colloidal patterning through electrohydrodynamics-assisted cone-jet printing to produce nanoscale patterns, and self-healing materials. (Aksay)
  • Experimental and computational studies on the low permeability of porous materials such as concrete and stones which plays a central role in the durability and frost damage of such materials, with emphasis on development and application of techniques based on poromechanics to measure very low permeabilities, molecular level understanding of the anomalous properties of liquids in nanometeric pores that contribute to very low permeabilities and, nucleation and propagation of ice dendrites through porous materials. (Scherer)
  • Experimental and computational fluid dynamics studies on mixing of solvent and anti-solvent streams in millisecond time scales to manipulate supersatutation levels, initiation of homogeneous nucleation and the ultimate formation of nanoparticles with narrow and controlled size distributions. (Prud'homme)
  • Theoretical and computational studies on fluid-solid and fluid-fluid multiphase flows and powder flows, with special focus on the instabilities leading to inhomogeneous structures, formulation of coarse-grained equations of motion that average over the small scale inhomogeneities and constitutive models development. (Sundaresan)
  • Studies on organic vapor jet printing to directly pattern organic semiconductors onto substrates with micron resolution from a vapor jet at atmospheric pressure, and gas-liquid multiphase transport in polymer electrolyte membrane fuel cells. (Benziger)
  • Computational studies and experiments (in collaboration with G. Ertl and H.-H. Rotermund at the FHI in Berlin) on spatiotemporal pattern formation on single crystal, microcomposite and microaddressable catalytic surfaces resulting from an interplay of reaction, diffusion and thermal effects. (Kevrekidis)
  • Study of shear and extensional rheology of nanostructured and associating polymers, such as block copolymers and ionomers, and using controlled flow to achieve alignment of block copolymer nanodomains in thin films. (Register)

Many of these projects are inter-disciplinary in nature and further details can be found in the research pages of the individual faculty mentioned.
