Dynamically reconfigurable complex emulsions via tunable interfacial tensions [PDF]

open access: yesNature, 2015
Emulsification is a powerful, well-known technique for mixing and dispersing immiscible components within a continuous liquid phase. Consequently, emulsions are central components of medicine, food and performance materials. Complex emulsions, including Janus droplets (that is, droplets with faces of differing chemistries) and multiple emulsions, are ...

Influence of different silica nanoparticles on drop size distributions in agitated liquid‐liquid systems [PDF]

open access: yes, 2019
The impact of different silica nanoparticles on rheology, interfacial tension and drop size distributions in liquid‐liquid systems is determined experimentally. The particles vary in wettability and specific surface area.

Linear viscoelasticity of emulsions : II. Measurements of the linear viscoelastic behavior of emulsions in the kilohertz range [PDF]

open access: yes, 1981
Linear viscoelasticity of emulsions in shear deformation in the kilohertz range is demonstrated experimentally. In order to avoid complications due to inertia effects, emulsions with small droplet sizes are studied.

The singular perturbation of surface tension in Hele-Shaw flows [PDF]

open access: yes, 2000
Morphological instabilities are common to pattern formation problems such as the non-equilibrium growth of crystals and directional solidification. Very small perturbations caused by noise originate convoluted interfacial patterns when surface tension is
