Dispersed lamellar phases in dense CO2
This proposal aims to explore these dispersed lamellar phases with a variety of F7H4 derivatives,to help understand their formation in supercritical CO2 (sc-CO2). The focus is... -
Hydrogen diffusion in zirconium alloys: The role of beta-phase morphology, co...
Zr is used extensively in nuclear reactors worldwide in a broad range of microstructural conditions due to its thermomechanical, corrosion and neutronic properties. However the... -
Muonium-photocarrier interaction in germanium
Having established the photo-MuSR method in intrinsic silicon to investigate excess carrier recombination lifetime and Mu-photocarrier dynamics in our previous experiments, we... -
Bi-disperse colloids: silica and microemulsions
Surprisingly little work has been done to gain understanding about the nature, stability and properties of nanoparticles dispersed in organic solvents (organosols). Recently... -
Micellar modifiers for CO2
This proposal focuses on a new approach to the formation of rod-like micelles in supercritical CO2 (scCO2). Recent successful high-pressure SANS (HP-SANS) results have shown for... -
Studies of the mechanism of hydrotropy
The objective is to refine current understanding about the mechanism of hydrotropy with respect to polarity and electrostatic character of hydrotropes and hydrophobic solutes... -
Gold-loaded microgels
Recent results show that gold nanoparticles (Au-NPs) can be included into microgels (MGs). UV-visible spectra (Figure 1) suggest the original Au-NP sols retain their size and... -
Opening up microemulsion phases in CO2
New types of water-in-CO2 microemulsions using mixed surfactant systems will be investigated by high-pressure SANS (HP-SANS). Exciting new results (see report on RB820030) have...
