Surfactant formation efficiency of fluorocarbon-hydrocarbon oligomers in supercritical CO2
The Journal of Chemical Physics, 2009 We use dissipative particle dynamics simulations to explore the phase behavior and solution properties of ABCBA type model surfactants in near-supercritical CO2 environment. We present design guidelines for functional surfactants with tunable properties. The block co-oligomers used in this study are made up of a CO2-phobic block having ethyl propionate

Redshifting TADF Emission With a Bora‐Triptycene Lewis Acid
Angewandte Chemie, EarlyView.Bathochromic emission shifting of donor–acceptor and multi‐resonant TADF emitters is achieved by adduct formation with a thia‐bora‐triptycene Lewis acid. TADF properties are retained on adduct formation whilst delivering > 100 nm redshift of the emission.

Fluoro-vs hydrocarbon surfactants: Why do they differ in wetting performance?
, 2020 Fluorosurfactants are the most effective compounds to lower the surface tension of aqueous solutions, but their wetting properties as related to low energy hydrocarbon solids are inferior to hydrocarbon trisiloxane surfactants, although the latter ...

Electro‐Organic Synthesis at a Stable Oil/Water/Solid Three‐Phase Interface Reactor
Angewandte Chemie, EarlyView.A porous membrane electrode (PME) reactor is developed to promote oil/water/solid three‐phase interfacial contact for electro‐organic synthesis. By promoting the formation of an oil/water interfacial region within or near an amphiphilic catalytic layer, the reactor enables efficient conversion of water‐insoluble organic reactants in aqueous ...

Selective Preconcentration of PFAS over Hydrocarbon Surfactants through Oil-Barrier Bubble-Bursting
Hydrocarbon surfactants are common interferents in low-cost methods for detecting per- and polyfluoroalkyl substances (PFAS). Here, we report an oil-barrier bubble-bursting strategy that combines rapid PFAS preconcentration via electrochemical aerosol ...
