Janus balance of amphiphilic colloidal particles.
We introduce the notion of "Janus balance" (J), defined as the dimensionless ratio of work to transfer an amphiphilic colloidal particle (a "Janus particle") from the oil-water interface into the oil phase, normalized by the work needed to move it into the water phase. The J value can be calculated simply from the interfacial contact angle and the geometry of Janus particles, without the need t...
متن کاملPolymer Blend Emulsions Stabilized by Janus Particles KYLE
Submitted for the MAR13 Meeting of The American Physical Society Polymer Blend Emulsions Stabilized by Janus Particles KYLE BRYSON, THOMAS RUSSELL, RYAN HAYWARD, University of Massachusetts Amherst — Kinetic trapping of bicontinuous polymer morphologies through the interfacial segregation of nanoparticles is of interest due to the unique combination of the properties of each component provided ...
متن کاملTepic - a New High Temperature Structural Foam
The formulation, processing characteristics, microstructure and mechanical properties of a new structural foam, suitable for use at service temperatures up to 200°C, are reported. In each of these respects, the foam is compared to an existing material, called APO-BMI that is currently in use. When these two foams are directly compared, the new foam, called TEPIC, is found to be superior in its ...
متن کاملPrecious Metals in High Temperature Geothermal Systems
High temperature geothermal systems are the modern analogue of epithermal precious metal ore deposits. In these systems, gold and silver are transported primarily as bisulfide complexes, with the precious metals being deposited in response to boiling and mixing of the deep geothermal fluid. In order for the geothermal system to produce an economic precious metal deposit within the typical lifet...
متن کاملLipid membrane-assisted condensation and assembly of amphiphilic Janus particles.
Amphiphilic Janus particles self-assemble into complex metastructures, but little is known about how their assembly might be modified by weak interactions with a nearby biological membrane surface. Here, we report an integrated experimental and molecular dynamics simulation study to investigate the self-assembly of amphiphilic Janus particles on a lipid membrane. We created an experimental syst...
