Structure development of resorcinol-formaldehyde gels: Microphase separation or colloid aggregation

Microphase Separation Transition for Polyelectrolyte Gels in Poor Solvents

The microphase separation transition in the weakly charged polyelectrolyte gels

Monitoring the gelation mechanism of resorcinol- formaldehyde gels by dynamic light scattering

Xerogels and porous materials for specific applications such as catalyst supports, CO2 capture, pollutant adsorption and selective membrane design require fine control of pore structure, which in turn requires improved understanding of the chemistry and physics of growth, aggregation and gelation processes governing nanostructure formation in these materials. We used time-resolved dynamic light...

Resorcinol-Formaldehyde (R-F) Resin

Resorcinol-formaldehyde resin "Russian Red" endodontic therapy.

Resorcinol-formaldehyde resin is a material used in endodontic therapy in many foreign countries. With immigration to the United States increasing, American dentists need to become familiar with resorcinol-formaldehyde therapy. It contains two potentially toxic components, formaldehyde (liquid) and resorcinol (powder). Zinc oxide or barium sulfate may be used for radiopacity. When 10% sodium hy...

Microphase separation in nonequilibrium biomembranes.

Compositional heterogeneities of cell membranes are thought to play an important role in many physiological processes. We study how variations in the membrane composition can be driven by nonthermal fluctuating forces and therefore show how these can occur relatively far from any critical point for the membrane. We show that the membrane steady state is not only controlled by the strength of th...
