Potential artifacts when evaluating the ecotoxicological effects of nanomaterials

Petersen E.J., Henry T.B., Zhao J., MacCuspie R.I., Kirschling T.L., Xing B., Dobrovolskaia M.A., Hackley V., White J.C., National Institute of Standards and Technology, US

Novel physicochemistries of engineered nanomaterials (ENMs) offer considerable commercial potential for new products and processes, but also the possibility of unforeseen and negative consequences upon ENM release into the environment. Investigations of ENM ecotoxicity have [...]

Assessment by Ames Test and Comet Assay of Toxicity Potential of Polymers Used to Develop a Field Capable Biosensor

Hebert A., Torosian S., Gleason K., Food and Drug Adminstration, US

Current methods of detecting food-borne pathogens take days to show and confirm results. There is a need for devices that decrease detection time. A field-capable rapid-detection device is being developed and in this study it [...]

Advancements in Microelectronics-Grade Carbon Nanotube Materials for NRAM® Device Manufacture and Analysis of Carbon Nanotube Mass in End User Devices

Lamb J.E., Gibbons S., Trichur R., Jiang Y., Mangelson K., Kremer K., Janzen D., Brewer Science, Inc, US

Providing materials for use in semiconductor manufacturing is challenging due to the extreme quality levels required for low metal ion and defect levels. This challenge is much greater for suppliers of materials containing long, high-aspect-ratio [...]

Conformance Control through In-situ Gelation of Silica Nanoparticles

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

Due to reservoir heterogeneities, oil recovery from fluid injection during secondary and/or tertiary recovery does not occur in an ideal piston-like displacement. Rather sweep efficiency can be much lower than 100% due to heterogeneities such [...]

Molecular Dynamics Simulation of Adsorption from Microemulsions and Surfactant Micellar Solutions at Solid-Liquid, Liquid-Liquid and Gas-Liquid interfaces

Akkutlu Y., Bui K., Silas J.A., Zelenev A., Saboowala H., Texas A&M University, US

In enhanced oil and gas recovery, the production of hydrocarbons is influenced by the ability of injected surfactants to adsorb and to modify interfacial tension at different interfaces. It has been demonstrated that surfactant and [...]

Nanocoating Testing for High Voltage Transmission Applications

McGuire D., Phillips A., Engelbrecht C., Gould A., Southern Company, US

The availability of reliable and affordable electric power is one of the most important characteristics of a modern society. Each citizen of the modern world has the expectation of light at the touch of a [...]

Nanotechnology in steel tubular goods: Challenges and Prospects

Castro P.A., Tenaris, AR

While traditional tubular steel tubular goods manufacturing and finishing technologies are getting closer to their limits, nanotechnology offers unique opportunities to achieve these new demands. It is in the field of coatings and nanostructured surfaces [...]

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 [...]
