Caption: Scrunched together, roughly 9,000 of these Bucky
Badgers could fit on the head of a pin. Nano Bucky, created in the research
lab of UW-Madison chemistry professor Robert J. Hamers, is composed of tiny
carbon nanofiber "hairs," each just 75 nanometers in diameter.
(A nanometer is equivalent to 1 billionth of a meter.) The nanofibers, one
of several nanostructured forms of carbon developed in the last several years,
have numerous potential applications and could play a role in the development
of such things as tiny sensors for detecting chemical and biological agents.
They may also have use in energy storage applications such as capacitors
and lithium-ion batteries. The fibers, and Nano Bucky, are "grown" in
a plasma deposition chamber where a mix of acetylene and ammonia gas are
used with electrical current to prompt the growth of the nanofibers on a
silicon substrate patterned with a nickel catalyst. The pattern for the catalyst
is composed on a computer and is then traced on the substrate by a beam of
electrons.
