1. Microscale Ionic Wind for Local Cooling Enhancement

   0.0 out of 5 stars 

   Online Presentations | 26 Oct 2007 | Contributor(s):: David B Go

   As the electronics industry continues to develop small, highly functional, mobile devices, new methods of cooling are required to manage the thermal requirements of the not only the chip but the entire system. Comfortable skin temperatures, small form factors, and limited power consumption are...

2. Piezoelectric Transducers: Strain Sensing and Energy Harvesting (and Frequency Tuning)

   0.0 out of 5 stars 

   Online Presentations | 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...

3. The Energy Problem: What the Helios Project Can Do About It

   5.0 out of 5 stars 

   Online Presentations | 13 Jun 2007 | Contributor(s):: Steven Chu

   Nobel Prize winner Steven Chu talks about the Helios Project for the 2007 'Science at the Theater' series at Berkeley Repertory Theater in Berkeley, California. He proposes an aggressive research program to transform the existing and future energy systems of the world away from technologies that...

4. Solid-State Lighting: An Opportunity for Nanotechnologists to Address the Energy Challenge

   0.0 out of 5 stars 

   Online Presentations | 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,...
