Rheological Characterization of a Novel Viscoelastic Surfactant for Subsurface Applications

Liebum M., Nguyen Q.P., The University of Texas at Austin, US

Viscoelastic solutions (VES) are used in many applications including oil and gas operations regarding reservoir stimulation and enhanced oil recovery to modify rheology properties in the subsurface. In general, the viscoelastic property of the surfactant [...]

Surfactants Nanocarriers to Enhanced oil Recovery (EOR)

Nascimento R.S.V., UFRJ, BR

The use organic surfactant nanocarriers as interfacial tension reducing agents is proposed in this work. These particles are able to permeate into the pores of the reservoir and release the surfactant by solubilization of the [...]

Polymer Nanofluid for enhanced oil recovery: A design of polystyrene nanoparticles, transport behavior evaluation and unconsolidated flooding test

de Araujo L.L.G.C., de Avila J.N.L., de Araujo L.L.G.C., de Avila J.N.L., Drexler S., Rodrigues Jr. J.A., Nascimento R.S.V., UFRJ, BR

This work focuses on the design of a nanoparticle containing polymer and surfactant containing that would be used in solution as a nanofluid for enhanced oil recovery. The nanoparticle is formed by crosslinking chemical reactions [...]

Surfactant Effect on Intercellular Transport of DNA, Proteins, and Electrolytes

Assan D., Gao X., Lai J.C.K., Leung S.W., Idaho State U, US

Surfactants play a key role on bodily functions at molecular level, such as cell signaling and signal transmission. Their importance in cell survival is well recognized, but the surfactant effect on intermolecular/interfacial mass transport is [...]

Effect of surfactant on TiO2/UV mediated heterogeneous photocatalytic degradation of DDT in contaminated water

Sinha S., Tapia-Orozco N.G., Acosta-Ramírez D.S., Rodríguez-Vázquez R., CINVESTAV, MX

The toxic effects from the use of pesticides are of great concern to the environment. The pesticides containers are not treated according to the Mexican normativity and hence increase the pollutant levels in the environment, [...]

Characterization of DNA Transport through a Semipermeable Membrane with the Effect of Surfactants

Leung S.W., Bartolin S., Daniels C.K., Lai J.C.K., Idaho State University, US

In current advances of biotechnology, various models of introduction of DNA into cells to alter their gene expression have important biomedical and bioengineering applications. However, the molecular mechanisms underlying how DNA’s cross cell and nuclear [...]

Bimodal Macro- Mesoporous Silica Network

García Martínez J., Abellán G., Carrillo A.I., Linares N., University of Alicante, ES

Herein we described the synthesis of novel kind of silica materials prepared at room temperature in the presence of cationic surfactant, more specifically a quaternary amine (tallow tetraamine) to obtain silica-based materials with attractive properties, [...]
