Rod-like micelles thicken CO2
Kieran Trickett,Dazun Xing,Robert M. Enick,Julian Eastoe,Martin J. Hollamby,Kevin J. Mutch,Sarah E. Rogers,Richard K. Heenan,David C. Steytler +8 more
TL;DR: The results show that it is possible to control surfactant aggregation to generate long, thin reversed micellar rods in denseCO(2), which at 10 wt % can lead to viscosity enhancements of up to 90% compared to pure CO(2).

Hydrocarbon Metallosurfactants for CO2
Kieran Trickett,Dazun Xing,Julian Eastoe,Robert M. Enick,Azmi Mohamed,Martin J. Hollamby,Stephen Cummings,Sarah E. Rogers,Richard K. Heenan +8 more
TL;DR: High-pressure small-angle neutron scattering has been used to study the surfactant aggregates in a normal organic solvent, cyclohexane, dense CO(2), and also mixtures of these two pure solvents and the results show that transition metal TC14 derivatives are viable compounds for incorporating reactive and functional metal ions into CO( 2.

High-temperature, high-pressure viscosity of n-octane and isooctane
Hseen O. Baled,Hseen O. Baled,Peter Koronaios,Dazun Xing,Randy Miles,Deepak Tapriyal,Isaac K. Gamwo,Matthew S. Newkirk,Rajendar R. Mallepally,Mark A. McHugh,Mark A. McHugh,Robert M. Enick,Robert M. Enick +12 more
TL;DR: In this article, a comparison of reported viscosity values with available literature data for n -octane and isooctane covering limited pressure and temperature ranges shows that the average absolute percent deviation (AAPD) varies between 1.0% and 2.5%.

Design principles for supercritical CO2 viscosifiers
Stephen Cummings,Dazun Xing,Robert M. Enick,Sarah E. Rogers,Richard K. Heenan,Isabelle Grillo,Julian Eastoe +6 more
TL;DR: In this paper, a series of semi-fluorinated F7H4 hybrid surfactants were designed to reveal the effects of hydrated cation radius (rhyd) on packing self-assembly in supercritical CO2 (scCO2).
