Four synthetic perylene bisimide-based polyaromatic (PA) surfactants with a structural or functional group difference in their attached hydrophilic/hydrophobic substituent side chains were used to probe structure-nanoaggregation relations organic media by molecular dynamics simulations and dynamic light scattering. The results from the simulated radial distribution functions scattering experiments indicate that variation structure of polarity groups leads significant variations association,...

Initial partitioning and aggregation of several uncharged polyaromatic (PA) molecules with the same core but different terminal moieties at oil-water interfaces from bulk oil phase were studied by molecular dynamics simulation. The partition PA between organic interface was highly dependent on moiety structure aromaticity phase. polarity ratio water phases showed a significant influence adsorption interface. presence hydrophobic aromatic in hindered process. Larger rings lowered interfacial...

One-step vibrational mixing has afforded the batch-scale preparation of a Janus emulsion. The fabrication particles (JPs) templated by emulsions was motivated topology and composition droplets being highly tunable controllable. Two immiscible polymerizable monomers were introduced as inner phases advanced geometry resultant JPs easily precisely controlled from "snowman" to "dumbbell" adjusting mass ratio two oils in initial surface coverage one lobe other tuned mixed surfactants. Moreover,...

Anisotropic particles, with morphology from crescent to moon shape and size micrometer nanometer scale, are fabricated in batch scale Janus emulsion as template. The strategy is also useful the synthesis of particles chemically distinct hemispheres.

Multicompartments in complex emulsions, which mimic the organelles of living cells, can spontaneously sequester reactants/products and confine spatially incompatible compounds. This provides opportunities to control spatiotemporal reaction processes be a sustainable high-efficiency platform for biphasic reactions even under stirring-free ambient temperatures. We introduce new multicompartment droplet microreactor based on one-step prepared emulsions. An organic/aqueous addition between...

A highly viscoelastic fluid formed by the ionic liquid-type surfactant 1-hexadecyl-3-nonyl imidazolium bromide ([C16imC9]Br) in water absence of any additive was studied.
