yield nanotube transistors
nanotubes are a natural for nanoelectronics.
They're tiny and they come in two kinds: semiconducting
and metallic. The problem is, they come jumbled
together. Separating them one by one is no
way to launch a revolution. But the solution
could be simple. Just add juice.
hints at quantum computer power
Quantum computers could be mind-bogglingly fast,
but the limited number of potential uses for them
makes it hard to imagine anyone but the government
paying to build them. Some MIT researchers are finding,
however, that quantum computers could be a lot more
useful than we think.
makes DNA more conductive
If DNA can be coaxed to conduct electricity efficiently,
the versatile molecules could spark a revolution
in electronics. One approach calls for converting
life's blueprint into a molecular cyborg.
process points to nanotech production
Being able to make tiny components is only half
the game in realizing the much-hyped future of nanotechnology.
Mass-producing the stuff is the next challenge.
Some relatively old-fashioned chemistry could be
pins DNA molecules in place
DNA molecules have a tendency to coil up and move
around, so using them as templates for precisely
positioned molecular electronic devices seems like
a stretch of the imagination. A few dabs of plastic
and some water, however, could fill in the picture.
