Spontaneous and reversible switch from amphiphilic to oil-like structures.

چکیده
Current theories assume that the amphiphilicity of biological membranes is always preserved. We observed that two hydrogen-bonding lipid layers in contact can spontaneously and reversibly lose their amphiphilic structure and turn into an assembly of oily complexes. This result opens a new angle for understanding the reorganization of lipids during membrane fusion, since similar complexes could fill the troubling hydrophobic voids displayed in the current models. The unique tribological properties described here may also find application in the development of novel nanolubricants.

Topological defects in lamellar phases: passages, and their fluctuations
In lamellar phases of ternary amphiphilic mixtures~ passages are tube-like connections of neighboring oil(or water-) layers. Passages form spontaneously due to the thermal fluctuations of the monolayers (or membranes), which separate oil and water. Analogous membrane conformations also exist in binary amphiphilic mixtures~ where the membranes are amphiphilic bilayers. We study the shape and the...

We report on a ternary isothermal system consisting of a poly(ethylene oxide)/poly(propylene oxide) (PEO/PPO) amphiphilic block copolymer, “water”, and “oil” (where “water” and “oil” are selective solvents for the different blocks), which exhibits the richest structural polymorphism ever observed (in equilibrium) inmixtures containing amphiphiles (such as block copolymers, surfactants, or lipid...
متن کاملMultifunctional amphiphilic carbonaceous microcapsules catalyze water/oil biphasic reactions.
Multifunctional amphiphilic hollow carbonaceous spheres assembled into Pickering emulsions exhibit reversible pH-dependent phase-transfer behavior and can efficiently catalyze water/oil biphasic reactions, facilitating the recycling of the catalysts and separation of the products.
متن کاملApplication of Nanoparticles for Chemical Enhanced Oil Recovery
In this paper, the potentials of using particles, especially nanoparticles, in enhanced oil recovery is investigated. The effect of different nanoparticles on wettability alteration, which is an important method to increase oil recovery from oil-wet reservoirs, is reviewed. The effect of different kinds of particles, namely solid inorganic particles, hydrophilic or hydrophobic nanoparticles, an...

A total of 700 day old female broiler chicks (Ross 308) were distributed into seven groupsin acompletely randomized designwith five replicates, and 20 chicks in each replicate. Dietary treatments, timeof the switch from an unsaturated sunflower oil (SFO) to a saturated tallow (T)dietary fat source, were: 1) SFO for the entire growth period (6 weeks), 2) SFO for 5 weeks followed byT for last wee...
