Inclusion of Electromagnetic Stress to explain Lithiated Silicon Nanowires

Boone D., Nanoscience Research Institute, US

Abstract: This study considers the electromagnetic stresses and simulates the lithium insertion into a silicon nanowire. The resulting model uses a multi-physics approach to explain the two detrimental effects that could result during the lithiated [...]

Charge Pumping for High-force, Large-displacement MEMS

Harvey IR., Baker B., Hogan A., Ford K., University of Utah Nanofab, US

Instead of making machines smaller that work well in the macro world, we envision a new class of machines that are specifically designed to take advantage of what works well in the micro-scale world. These [...]

Modeling and Simulation of PVDF-TrFE Based MEMS Scale Cantilever Type Energy Harvesters

Toprak A., Tigli O., University of Miami, US

We present the FEM modeling and simulation of a cantilever type piezoelectric energy harvester constructed using PVDF-TrFE. PVDF-TrFE is a CMOS compatible, soft piezoelectric polymer with a moderate electromechanical coupling coefficient. It is also flexible [...]

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 [...]

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 [...]

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 [...]
