Carbon nanotubes -- strong tubular structures formed from a
single layer of carbon atoms and only about a billionth of a
meter in diameter -- display previously unknown properties with
significant technological potential, a new University of North
Carolina at Chapel Hill study shows.
Small Times Magazine has released the findings of its second
annual survey profiling universities' strengths in micro and
nanotechnologies... More
Surprisingly, carbon tubes so thin it would take several million
lying side by side to cover an inch require considerably more
energy to roll across some surfaces than they do to slide across
the same surfaces.
Getting permission to go to the bathroom during class can be
trouble enough for healthy children, but imagine how much more
difficult it would be if you couldn’t talk. That’s one of Travis
Ward’s many challenges. Travis was born with cerebral palsy
-- a disabling neurological and motor skills disorder -- and
a genetic error in metabolism. The upbeat 16-year-old Durham
native can’t run, can’t ride a bicycle and can’t perform countless
tasks so many other children take for granted, including talking.
Using a sophisticated device known as a scanning tunneling microscope,
chemists for the first time have observed directly how hydrogen
atoms behave and bond to surfaces at high temperatures.
Carbon tubes so thin it would take several million lying side
by side to cover an inch show such remarkable flexibility, strength
and resiliency that industry should be able to incorporate them
into high performance sports and aerospace materials, according
to new experiments.
An "exciting" new industrial process for separating liquid chemicals
from one another -- a technique that promises to cut release of
toxic substances into the environment -- has been developed.
