Carbon Nanotubes & Quantum Dots: Army Thinks VERY Small
Now this will be the plague
with which the Lord will strike all the peoples
who have gone to war against Jerusalem;
their flesh will rot while they stand on their feet,
and their eyes will rot in their sockets,
and their tongue will rot in their mouth.
Zechariah 14:12
One Army Research Office project is looking to replace traditional silicon-based semiconductors
with more efficient carbon nanotubes, program manager Joe Qiu ...
The new technology is particularly useful at the very high frequencies (30-plus gigahertz)
and very short wavelengths (millimeter wave) that the telecommunications industry wants to use for 5G networks – including on military bases –
and for whatever replaces 5G.
“The initial deployment of 5G,
they will be lower than six gigahertz, but there are plans…
to improve frequencies to 28 GHz and higher,”
( hummmm I wonder what could go wrong with that?)
Qiu said.
“It’s not just 5G — it’s beyond 5G.”
While the Chinese-born, US-trained Qiu is a physicist-
turned-engineer-
turned-program manager,
Myers is a mathematician and head of the mathematical sciences division at ARO –
a field, he jokes, notoriously disconnected from mundane reality.
Qiu’s carbon nanotubes are a fraction of the size of a single human hair.
Their lengths vary widely, but their thickness is typically six nanometers or less.
Myers is funding research on quantum dots, miniscule crystals of semiconductor whose longest dimension is no more than six nanometers, meaning they could conceivably fit inside a nanotube.
( hummmm again...or maybe they could fit inside a human body? I don't know,
via a vaccine of food or? I guess if we are not raptured soon, we may see?)
The downside, Myers went on,
is that it’s much harder to design electronics using quantum dots.
Classical models of physics start to fail
as you start to enter the strange domain of quantum mechanics,
where seemingly solid objects turn into fuzzy fields of energy
that can pulse and jump in unpredictable ways.
Unlike traditional electronics that use electrical charges to represent 1s and 0s,
“the physics of what’s going on isn’t as clean as zero/one anymore,” he said.
“It’s got some probability of being a zero, some probability of being a one.”
( well that sounds safe...or...maybe not so much...let's fiddle with it and see)
Of course these things are always put in the plus 'good' side:
What kind of improved technologies could you use Cai’s model to design?
Besides the QLED televisions already on sale,
Myers said there’s interest from multiple parts of the Army Research Laboratory
that work on everything from solar panels –
a useful complement to fuel-hungry diesel generators
and heavy lithium-iron batteries –
to military sensors and other electronics.
There’s a potential medical application in improving CT scans,
as well, which is potentially life-changing not just for civilians
but for survivors of skull-rattling roadside bombs.
( all 'good' things....
but I have noticed over time that...
there is often a dark, not so good side...
of anything mankind does
and it
reminds me of):
4 The serpent said to the woman,
“You surely will not die!
5 For God knows that in the day you eat from it
your eyes will be opened,
and you will be like God,
knowing good and evil.”
6 When the woman saw that the tree was good for food,
and that it was a delight to the eyes,
and that the tree was desirable to make one wise, ........
Genesis 3:4-6
