Tough and strong bioinspired nanocomposites with interfacial cross-links.
Strength and toughness are two mechanical properties that are generally mutually exclusive but highly sought-after in the design of advanced composite materials. There has only been limited progress in achieving both high strength and toughness in composite materials. However, the fundamental underlying mechanics remain largely unexplored, especially at the nanoscale. Inspired by the lamellar s...
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...
متن کاملAdsorption Dynamics in Pickering Emulsions
We investigate the adsorption dynamics of colloidal particles to a liquid/liquid interface. Such an analysis is important in the formation of Pickering emulsions. Using a free energy formulation that has been used for adsorption of surfactants, we obtain the time evolution of the surface coverage and dynamic surface tension. We estimate the characteristic time for adsorption, and show that it c...
متن کاملCrude Oil Interfacial Tension Reduction and Reservoir Wettability Alteration with Graphite or Activated Carbon/Silica Nanohybrid Pickering Emulsions
In this research, two carbon structures silica nanohybrids Pickering emulsions were prepared. Graphite and activated carbon were carbon allotropes with different morphologies of laminar and spherical, respectively. The effect of carbon morphology investigated on the related silica nanohybrids Pickeringemulsions for C-EOR. Therefore, nanohybrids were prepared with graphite and activated carbon t...
متن کاملThermodynamically 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...
