Lithium-ion batteries
If you own any handheld electronic gadget, chances are you own a lithium–ion battery. The $10 billion industry wouldn't be possible without the innovation of a possible candidate for the Nobel prize in chemistry, John Goodenough. He was the first to use lithium cobalt oxide as the cathode material in a lithium battery, which meant that stable materials could be used as the corresponding anode. Even today, most lithium-ion batteries use lithium cobalt oxide. Goodenough has continued working on materials that could be used as cathodes in lithium ion batteries.
Experts available:
• Bruce Dunn, a professional colleague of Goodenough’s on a DOE-funded panel. Dunn’s research includes work on the electrochemistry of new materials that could be used to store electricity. o Title: Professor, Materials Science & Engineering, University of California, Los Angeles o Email: bdunn@ucla.edu o Phone: 310-825-1519 o Webpage: http://www.seas.ucla.edu/ms/faculty1/dunn.html o Note: Dunn is available during Pacific Daylight Time business hours.
• Gary Rubloff heads a DOE-funded research project that examines ways nanostructures can be used to store electrical energy. Many of Rubloff’s efforts have focused on improving lithium–ion batteries with nanostructures. o Title: Minta Martin Professor, Materials Science & Engineering, University of Maryland, College Park.

Nanowires
Nanowires are tiny crystalline fibers, typically less than one hundred nanometer across, and thousands of nanometers long. Nanowires are grown starting with a tiny bead of liquid gold or other metal that is placed in a vapor of the nanowire material. The material is attracted to the beads and grows into a long thin spike. Nanowires display an array of physical properties that depend not only on the material but also on their diameter, for example they conduct electricity differently than a large piece of the material they are made with. Peidong Yang a possible candidate for the Nobel prize in physics, has examined many different types of nanowires and their properties, including the ability to conduct a laser beam down its extremely narrow diameter. They can be used in quantum computers, as when two nanowires cross it creates a quantum dot; in flexible solar cells; and in tiny self-contained sensors.
