The network structure of a steroid/cyclohexane physical gel

Effect of Sterol Type on Structure of Tubules in Sterol + γ-Oryzanol-Based Organogels

“…The extent to which the acid moiety can be varied without losing the gelling capability would be an interesting subject of a subsequent study-some examples are known if the requirement is dropped that the ester originates from a food-related source. 22,23,[27][28][29] Figure 6 (two bars at the right) confirms that the gels with tall oil esters do not form a firm gel.…”

“…Although little is known on how these tubules aggregate to form a three-dimensional network, it is presently assumed that the structure will be very similar to other fibrillar networks. 22,23 It has been observed that γ-oryzanol-rich systems tend to be less hazy and can be cooled more easily to temperatures below the melting temperature of the resulting gel without immediate solidification occurring, which has been taken as circumstantial evidence that these tubules show less tendency to aggregate than tubules formed in β-sitosterol-rich mixtures.…”

Small-Angle Scattering and Electron Microscopy Investigation of Nanotubules Made from a Perfluoroalkylated Glucophospholipid

“…Among the few systems rigorously studied by small-angle X-ray scattering (SAXS) and small-angle neutron scattering (SANS) are some gels formed by a steroid derivative in various organic solvents (13)(14)(15). These gels were constituted by micron-long rigid fibers (diameter ϳ100 Å) connected by microcrystalline domains.…”

A Novel Route to Multiphase Polymer Systems Containing Nano‐Droplets: Radical Polymerization of Vinylic Monomers in Gelled Water‐in‐Oil Miniemulsions

“…This is why we decided to apply an organo-gelator to kinetically freeze the monomer phase. As organo-gelators usually gel toward rod-like aggregates, [15] there is no entropic penalty destabilizing the miniemulsions. Afterwards, this gelled system is polymerized throughout, however staring from a kinetically trapped situation to generate the demanded highly disperse hybrid material.…”
