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 [...]

Metal Organo-Clays as potential adsorbents for hydrogen storage

Azzouz A., Nousir S., Bouazizi N., Roy R., University of Quebec at Montreal, CA

Metal-Organo-Clays (MOC) are novel microporous matrices that can be synthesized via the in-situ formation of Cu, Fe or Pd nanoparticles in montmorillonite-supported polyol dendrimers. This is a new concept that has scarcely been tackled so [...]

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 [...]

A Study on the System Configuration for the Flywheel Energy Storage Device to be Applied to the Railway System

Lee J-H., Korea Railroad Research Institute, KR

A system configuration to be applied to the railway system using flywheel energy storage system to store regenerative energy which is produced during the braking period of the train is presented. The proposed FESS (Flywheel [...]

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 [...]

MWCNTs/metal oxide nanocomposite as potential material for supercapacitors application in acidic and neutral media

Adekunle A.S., Ozoemena K.I., Agboola B.O., Ebenso E.E., North-West University, ZA

Carbon based supercapacitor electrodes have been attractive due to their high surface area and porous nature. Studies have shown that the carbon nanotube-metal oxide (CNT-MO) nanocomposite modified electrodes exhibited huge capacitive current in some electrolytes. [...]

Synthesis and characterization of (polypyrrole/carbon) nanotubes/metal oxide composites for application as supercapacitors

de Oliveira A.H.P., de Oliveira H.P., de Oliveira A.H.P., de Oliveira H.P., UNIVASF, BR

The development of eco-friendly technologies such as hybrid vehicles requires more efficient high power energy storage materials, viz. supercapacitors. As reported in our previous work, the association of polypyrrole and carbon derivatives (modified graphene oxide [...]

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 [...]
