Summary of "Physics of Active Emulsions."

Phase separating systems that are maintained away from thermodynamic equilibrium via molecular processes represent a class of active systems, which we call \textit{ active emulsions}. These systems are driven by external energy input for example provided by an external fuel reservoir. The external energy input gives rise to novel phenomena that are not present in passive systems. For instance, concentration gradients can spatially organise emulsions and cause novel droplet size distributions. Another example are active droplets that are subject to chemical reactions such that their nucleation and size can be controlled and they can spontaneously divide. In this review we discuss the physics of phase separation and emulsions and show how the concepts that governs such phenomena can be extended to capture the physics of active emulsions. This physics is relevant to the spatial organisation of the biochemistry in living cells, for the development novel applications in chemical engineering and models for the origin of life.

MRI-guided Transurethral Insonation of Silica-shell Phase-shift Emulsions in the Prostate with an Advanced Navigation Platform.

In this study, the efficacy of transurethral insonation of silica-shell ultrasound-triggered phase-shift emulsions (sUPEs) doped with MR contrast was evaluated. The influence of sUPEs on MR imaging as...

Switchable oil-in-water emulsions stabilized by like-charged surfactant and particles at very low concentration.

A novel CO2/N2 switchable n-decane-in-water emulsion was prepared which is stabilized by a CO2/N2 switchable surfactant (DDMA) in cationic form in combination with positively charged alumina nanoparti...

Surface modification of microcrystalline cellulose: Physicochemical characterization and applications in the Stabilization of Pickering emulsions.

The phenomenon of polymer adsorption was applied to modify the surface of microcrystalline cellulose (MCC). The active polymer sodium carboxymethyl cellulose (CMCNa), having different molecular weight...

Destabilizing Pickering emulsions using fumed silica particles with different wettabilities.

Whereas hydrophobic colloidal particles are known to destabilize foams and emulsions stabilized with surfactants, their use for destabilizing Pickering emulsions is unexplored. Pickering emulsions dif...

The simulated in vitro infant gastrointestinal digestion of droplets covered with milk fat globule membrane polar lipids concentrate.

Milk fat globule membrane polar lipids (MPL) are increasingly used as the surface-active components for emulsions in many infant food products. However, the precise effect of the emulsifier MPL on the...

Medical and Biotech [MESH] Definitions

Colloids formed by the combination of two immiscible liquids such as oil and water. Lipid-in-water emulsions are usually liquid, like milk or lotion. Water-in-lipid emulsions tend to be creams. The formation of emulsions may be aided by amphiphatic molecules that surround one component of the system to form MICELLES.

Emulsions of fats or lipids used primarily in parenteral feeding.

An organic amine proton acceptor. It is used in the synthesis of surface-active agents and pharmaceuticals; as an emulsifying agent for cosmetic creams and lotions, mineral oil and paraffin wax emulsions, as a biological buffer, and used as an alkalizer. (From Merck, 11th ed; Martindale, The Extra Pharmacopoeia, 30th ed, p1424)

Antioxidant for foods, fats, oils, ethers, emulsions, waxes, and transformer oils.

Molecules that contain multiple active sites which are used to catalyze more than one enzymatic reaction. Proteins in this class generally contain multiple active sites within a single peptide chain and may also contain more than one enzymatically active subunit. They are distinguished from MULTIENZYME COMPLEXES in that their subunits are not found as distinct enzymes.
