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 [...]

Adsorption of Functionalized Silica Nanoparticles on Swelling Clay Minerals

Pham H-T, Nguyen Q.P., The University of Texas at Austin, US

Successful application of nanoparticles is dependent on understanding the mobility, retention, and transport fate of nanoparticles in natural formations. These aspects are greatly influenced by subsurface environmental conditions such as electrolyte type and concentration, temperature, [...]

Interaction of Surface Modified Silica Nanoparticles with Clay Minerals

Metin C.O., Nguyen Q.P., The University of Texas at Austin, US

The interaction of silica nanoparticles with montmorillonite clay was investigated by visual swelling tests, Fourier Transform Infrared (FTIR), and x-ray diffraction (XRD). The adsorption of silica nanoparticles onto montmorillonite was also studied with a UV-Vis [...]

Secondary Use Energy Storage

Starke M., Irimger P., Ollis B., Andrews G., Karlson P., Thabiappah S., Rosenfeld P., Massin S., Oak Ridge National Laboratory, US

This study presents the testing of a community energy storage system composed of repurposed used electric or plug-in hybrid electric vehicle (EV/PHEV) battery packs. The expectation is that the vehicular batteries will be replaced with [...]

Nanostructured Acetylcholinesterase (ACHE) Memristor/Memcapacitor Mimicks Brachyhypopomus Electric Fish’s Signal-Cloaking Behavior

Chen E.T., Thornton J., Advanced Biomimetic Sensors, Inc., US

The Brachyhypopomus Electric (BHE) fish is known for its signal-cloaking behavior that allows it to avoid predators by shifting its electroreceptive pulses from low frequency to less detectable high-frequency through a phase-delay “head-tail” Electric Organ [...]

Architecturing Carbon Nanotube-based Flexible Solid State Supercapacitor

Adu K, Ma D., Radall C., Rajagopalan R., Armstrong P., Stigers S., The Pennsylvania State University, US

We report a novel post synthesis self-assembly technique that transforms the trillion of carbon nanotubes into a robust, flexible and binder-free membrane and demonstrate its application in designing flexible bipolar solid state supercapacitor with high [...]

Assessing damage to graphite electrodes in bromine redox flow battery systems

Bistrikaa A.A., Brekkenb T.K.A., von Jouanneb A., Lernerc M.M., Yokochia A.F.T., NRGindependence, Oregon State University, US

A crucial metric in harvesting renewable and intermittent power resources is widely understood to be the ability to, and cost effectiveness of, storing energy. Large chemical systems, such as Redox Flow Batteries (RFBs), are a [...]

Seawater Flow Battery as Technology Platform

Schubert P.J., Fu Y., IUPUI, US

Grid-level storage of renewable energy using electrolytes from seawater is a platform technology with multiple byproducts and use-case scenarios. The core application is to provide load-leveling for intermittent sources such as wind and solar. Membranes [...]
