Determination of Pore Size Distribution of Nafion/Sulfated beta-Cyclodextrin

Jeon J-D, Lee B.H., Kwak S-Y, Seoul National Univesity, KR

Direct methanol fuel cells are promising candidates for portable power sources and transport applications. One of the critical problems hindering the commercialization of DMFCs is high methanol permeation rate across proton-exchange membranes. In this study, [...]

Heat is the Enemy of Energy Efficiency

Forder D., Fox P., TAG Technology, US

The flow of heat has been a major challenge to engineers for centuries. A new nanotech material, developed by TAG technologies, can block the flow of heat from one direction only. This presentation will present [...]

Dynamics of Water in Nafion Fuel Cell Membranes: the Effects of

Moilanen D.E., Piletic I.R., Fayer M.D., Stanford University, US

The complex environment experienced by water molecules in the hydrophilic channels of Nafion membranes is studied by ultrafast infrared pump-probe spectroscopy. A wavelength dependent study of the vibrational lifetime of the O-D stretch of dilute [...]

Building Green with Nanotechnology

Elvin G., Green Technology Forum, US

Nanotechnology, the manipulation of matter at the molecular scale, is opening new possibilities in green building through products like solar energy collecting paints, nanogel high-insulating translucent panels, and heat-absorbing windows. Even more dramatic breakthroughs are [...]

Molecular Building Blocks for Efficient Solid State Lighting

Burrows P.E., Sapochak L.S., Pacific Northwest National laboratory, US

General illumination consumes 22% of the electricity generated in the U.S. This huge proportion is partly due to the ubiquity of artificial lighting but also the inefficiency of converting electrical energy to light. Incandescent lightbulbs [...]

Nano-structures materials for Energy Direct Conversion and Fuel Breeding

Popa-Simil L., LAVM Llc., US

The new developments in nano-structures and high-energy superconductors open the road for better nuclear energy. A new family of new nuclear fuels as well as energy harvesting blankets to be used as active shielding in [...]

Bulk Heterojunction Organic-Inorganic Photovoltaic Cell Based on Doped Silicon Nanowires

Goncher G., Noice L., Solanki R., Portland State University, US

A bulk heterojunction organic-inorganic photovoltaic cell was fabricated by growing doped n-type silicon nanowires on an n+ silicon substrate. A p-type organic semiconductor (P3HT) was then coated over the nanowires. The device was completed by [...]
