Carbon Nanotubes bring digital music (or at least sound) to the sea

by on Jun.14, 2010, under Articles, Science

Carbon nanotubes create underwater sonar speakers (NewScientist)

Yes my friends. Carbon Nanotubes are back in the news. And this time, they’re replacing our underwater speakers. Long range sonar no longer has to look like something your uncle toted around on his shoulder in the 80s in order to make himself go deaf.

YAY CARBON NANOTUBES!

Nanotubes Track Cellular Toxins
Technology Review Dec. 15, 2008
*************************
Researchers at MIT have found that
carbon nanotubes wrapped with a
small piece of DNA can serve as
highly sensitive biological sensors
for detecting single molecules in
living cells in real time, at a
sensitivity that far exceeds that of
fluorescent dyes, the standard tool
for molecular imaging. The sensors
could eventually be used to monitor…

Flawed nanotubes could be perfect
silicon replacement
New Scientist Tech Dec. 15, 2008
*************************
Oak Ridge National Laboratory
scientists have have discovered that
a circuit of nanotubes can only
guide a current if some of the tubes
carry structural defects. Carbon
nanotubes are better conductors than
silicon at transmitting charge,
which means nanotube circuits could
boost computing speeds while
reducing chip size. Structural
defects,…

Drug grenades explode right on target
New Scientist news service Oct. 22, 2008
*************************
Chemical engineers at Ghent
University in Belgium have developed
a novel drug delivery system using a
rigid but porous polymer membrane
that contains a gel that expands in
contact with water. This bursts the
capsule open to release carbon
nanotubes or other
nanomaterial-based drug carriers,
which normally diffuse very slowly
through target…

Sheets made of carbon nanotubes
behave like a loudspeaker when
zapped with a varying electric
current, say researchers at Tsinghua
University in Beijing and could lead
to new generation of cheap, flat

The sound is generated by the
thermoacoustic effect. The flexible

Invention: Cancer nanobomb
New ScientistTech Nov. 10, 2008
*************************
Balaji Panchapakesan at the
University of Delaware suggests
destroying cancers in situ using
exploding nanotubes. His idea is to
fill carbon nanotubes with water
before injecting them into a tumor.
The area is then zapped with laser
light, which causes the water inside
the nanotubes to boil. The
tremendous pressure created by the
heating causes…

Nanotube ‘longboats’ slaughter
cancer cells
New Scientist news service Sep. 6, 2008
*************************
MIT researchers have attached a
modified version of potent cancer
drug cisplatin and folic acid to
carbon nanotubes, killing cells with
folic acid receptors more
effectively than cells without them.
These receptors are most numerous on
cancer cells, so the hope is that
the drug may target tumors in the
body and spare healthy cells….
