Aluminum: a safe, economical, high energy density material for energy storage, transport and splitting water to make hydrogen on demand
30 Mar 2009 | | Contributor(s):: Jerry M. Woodall
In 1968, a team lead by the author discovered that liquid gallium saturated with aluminum at room temperature would split water into hydrogen gas, alumina and heat. More recently his current team has discovered that bulk, solid Al rich alloys will also split water in the same manner. Since 1) the...

Piezoelectric Transducers: Strain Sensing and Energy Harvesting (and Frequency Tuning)
15 Jun 2007 | | Contributor(s):: Toshikazu Nishida
Acoustic pressure or mechanical force sensing via piezoelectric coupling is closely related to the harvesting of electrical energy from acoustical and mechanical energy sources. In this talk, mesoscale and microscale piezoelectric transducers for acoustic and vibrational sensing and energy...
Solid-State Lighting: An Opportunity for Nanotechnologists to Address the Energy Challenge
25 Apr 2007 | | Contributor(s):: Timothy D. Sands
More than one-fifth of the electrical power consumed in the U.S. is used for general illumination. Much of this energy is wasted to heat filaments in incandescent lamps, a century-old technology with an efficiency of about 5%. Fluorescent lighting is more efficient, but problems of color quality,...
