Emergent phenomena in three systems : two-component droplets, synthetic ecosystems, and elastomeric focusing
Abstract/Contents
- Abstract
- This thesis covers projects on three different systems where interactions within each system lead to behaviors that aren't readily evident from the individual parts. The first project involves the behavior of two-component liquids. Certain mixtures do not spread on clean glass as their individual components do, but instead form droplets which display unusual properties such as self-attraction, chasing, and absence of contact line pinning. I discuss the physical phenomena underlying these effects and show several examples of devices that can be created with this understanding. The second project involves a synthetic microbial community I created by genetic barcoding. Community members interact by competing with each other for shared nutrients, and with experiments and modeling I investigate the limits of treating each member equally in the context of neutral theories debated in ecology. The last project leverages interactions between different materials to obtain greatly amplified displacements due to thermal expansion. I exploit this effect to create a new type of microfluidic valve that can be actuated with electricity or light.
