Thermodynamically stable pickering emulsions.
We show that under appropriate conditions, mixtures of oil, water, and nanoparticles form thermodynamically stable oil-in-water emulsions with monodisperse droplet diameters in the range of 30-150 nm. This observation challenges current wisdom that so-called Pickering emulsions are at most metastable and points to a new class of mesoscopic equilibrium structures. Thermodynamic stability is demo...
متن کاملArtificial Surface Tension to Stabilize Captured Shockwaves
Computationally captured shockwaves, especially at very high Mach number, often display anomalous behavior not encountered in nature. Figure 1 shows three of the most notorious examples. The passage of a normal shock over a slightly perturbed mesh was observed to be unstable by Quirk. However, it was subsequently discovered that neither the mesh perturbation nor the shock motion was always need...
متن کاملEmulsions stabilised by whey protein microgel particles: towards food-grade Pickering emulsions.
We have investigated a new class of food-grade particles, whey protein microgels, as stabilisers of triglyceride-water emulsions. The sub-micron particles stabilized oil-in-water emulsions at all pH with and without salt. All emulsions creamed but exhibited exceptional resistance to coalescence. Clear correlations exist between the properties of the microgels in aqueous dispersion and the resul...
متن کاملPickering emulsions stabilized by surface-modified Fe3O4 nanoparticles.
Unmodified Fe(3)O(4) nanoparticles do not stabilize Pickering emulsions of a polar oil like butyl butyrate. In order to obtain stable emulsions, the Fe(3)O(4) nanoparticles were modified by either carboxylic acid (RCOOH) or silane coupling agents (RSi(OC(2)H(5))(3)) to increase their hydrophobicity. The influence of such surface modification on the stability of the resultant Pickering emulsions...

[To my family for their love and support] iv ACKNOWLEDGEMENTS There are many people I would like to thank for their support throughout my Ph.D. study at Georgia Tech. I would like first express my tons of gratitude to my advisor Dr. Behrens for his invaluable support that I will remember for ever. I will remember his great guidance whenever I encounter a problem in my thesis work; I will rememb...
