Recently we have suggested that negative thermal expansion materials will also show an effect called pressure-induced softening, where shown that the elastic stiffness is...

Recently, a novel type of Bose-Einstein condensation (BEC) of spin-orbit excitons has been proposed in Mott insulator Ca2RuO4. In the recent INS study, we have observed...

There is a well-documented track record of research into water-in-CO2 (w/c) microemulsions. Using newly discovered CO2 compatible surfactants, the next step is to explore...

Long-term stable CO2 foams were generated under high temperature (120 ºC) and high pressure (12 MPa) (HPHT) in our laboratory using a C22-tailed weak cationic surfactant,...

Recent SANS studies of an unusual headgroup-free surfactant (Nohead FC6-HC4) produced data that implied the formation of W/CO2 microemulsions (MEs) at a particular pressure (P)...

Over the last two decades, many polymers have been tested to increase CO2 viscosity for applications in enhanced oil recovery using CO2 (CO2-EOR). Unfortunately, conventional...

CO2 foams can be formed in water/carbon dioxide (W/CO2) mixtures with the aid of W/CO2 interfacially active hydrocarbon surfactants and surface treated silica nanoparticles...

Recent studies implied an unusual headgroup (HG)-free, fluorocarbon (FC) surfactant Nohead FC6-HC4 to form stable, W/CO2 nanodispersions (W/C NDs). With the unusual surfactant...

We use SANS to study synthesis of interpenetrating polymer network in supercritical CO2 in situ at sans2D. The initial system contains an inorganic polymer network, hydrophilic...
