The common theme of Dr. Ma’s research group, Complex Fluids Laboratory, is to understand the complex flow behavior of complex fluids. Of particular interests are foams, emulsions, biological fluids, and fluids containing nanoparticles. The ultimate goal is to develop effective, scalable techniques for processing these materials into multifunctional, high performance articles (e.g., films, fibers, and polymer composites). Dr. Ma is particularly interested in the following areas:
- Phase Behavior and Rheology of Fluids Containing Nanoparticles
A key challenge in realizing the full potential of nanoparticles is the control of their spatial distribution during processing and application. To overcome this challenge, Dr. Ma’s group focuses on understanding:
- Phase behavior of different types of nanoparticles and their mixtures
- Interplay between different length scales, namely the length scale of the particles (nm), assembly of particles (nm – μm), and processing length scale (>μm)
Of particular interest are: 1) the effect of confinement on the assembly of nanoparticles, 2) flow through porous media (e.g. nanoparticle distribution during resin infusion), and 3) the creation of multifunctional metamaterials.
- Nanoparticle-stabilized Foams and Emulsions for Enhanced Oil Recovery Applications
In oil recovery, stranded oil is oil that cannot be recovered by primary or secondary means. This type of oil is trapped by viscous, capillary, and interfacial forces within the pores in rock formation and accounts for about two-thirds of the original oil in place (~400 billion barrels in the US alone). Enhanced oil recovery (EOR), also known as tertiary recovery, focuses on modifying fluid flow to improve oil displacement in the reservoir. Dr. Ma’s vision is to develop next generation EOR technology using nanoparticle-stabilized foams and emulsions.
- Polymer Nanocomposites for Aerospace and Energy Applications
Nanoparticles are often added to a polymer matrix as a conductive or mechanical reinforcement component, but many nanoparticles also possess piezoresistive or piezoelectric properties that can be further exploited as a sensing element. Dr Ma’s idea is to use nanoparticles as “smart sensors” for structural health monitoring in aerospace and energy applications.
