Computer Chips Keeps Getting Smaller and Smaller
Moore's Law in a nutshell: "The number of transistors that can be inexpensively placed on an integrated circuit is increasing exponentially, doubling approximately every two years."
"Silicon chips could become even more densely packed with
transistors thanks to a breakthrough that carves features
in silicon that are many times smaller than the wavelength
of the light used to make them."
"The new approach produces grids of parallel lines just 25
nanometers wide using light with a wavelength of 351 nm.
The grids are not functional circuits but could be made
into working chips by adding extra small features."

Nano-Satellites By 2011?
If you like the number nine, then the N-Prize is for you.
"For those of you who haven yet heard of the N-Prize, the
N-Prize is a £9,999.99 (sterling) cash prize which can be
claimed by any individual, or group, who are able to prove
that they have put into orbit a small satellite. The satellite
must weigh between 9.99 and 19.99 grams, and must orbit the
Earth at least 9 times. This project must be done within a
budget of £999.99 (sterling)."
"In order to be eligible for the award, the winning team must complete
the challenge before 19:19:09 (GMT) on 19 September 2011."
The Space Fellowship is an "international news and information network dedicated to the development of the aerospace industry."
Q: "Do you think there is a genuine market for nano-satellites
or is this more of a 'stunt' to get attention towards
private spaceflight?" -- International Space Fellowship
A: "Yes and no, on both counts. I suspect there is a use for
nano-satellites. If someone today can put something in orbit
which takes a single fuzzy picture of the earth, then tomorrow
someone will launch a nanosatellite that sends back live video
in visible and infra-red. Before you know it, tiny satellites
will be doing all kinds of neat stuff, either in isolation or
as part of a swarm." -- N-Prize founder Dr. Paul Dear

We Need Nano-Literate Politicians
Forbes.com quoted J. Clarence Davies, a "former Environmental Protection Agency (EPA) official who now serves as a senior adviser to the Project on Emerging Nanotechnologies at the Woodrow Wilson Center in Washington," saying:
"The future of nanotechnology is extraordinary. When you
start crossing it with synthetic biology and artificial
intelligence and so on, science fiction looks very pale
in comparison."
1st- and 2nd-generation Nanotechnology is happending now.
"From March 2006 to February 2007, reckons the Project
on Emerging Nanotechnologies, the number of manufactured
goods using nanotech tripled to 600."--Forbes.com

NIST is Playing Nanosoccer
For the 2nd year in a row, NIST (National Institute of Standards and Technology) held a nanosoccer competition at the 2008 RoboCup. The RoboCup is an "international organization dedicated to using the game of soccer as a testing ground for the robotics technologies of the future."
"Imagine a robotic David Beckham six times smaller than
an amoeba playing with a 'soccer ball' no wider than a
human hair ... with all of the action happening on a
field the size of single grain of rice."
Nano-scale robots are nanobots. According to NIST.gov, "about 200 nanobots could stretch in a line across the top of a plain M&M candy." NIST.gov::NIST and Nanosoccer[20 July 2008, top] |

The Powers of Ten
The Nanotech SmallBlog extends a Thank You to the Center for Responsible Nanotechnology for passing along a hyperlink to the film "Powers of Ten."
"It's fascinating, though, to try placing the tiny segment
of time in which we live into a larger perspective. Inspired
by the iconic film, 'Powers of Ten,' we performed a similar
exercise going backward and forward in time by powers of ten,
with results that generated a lot of interest on the Internet.
Posthumans?
"More likely is that our civilization will end, as has every one
before it, and that its replacement will be a new civilization
built upon the old. But the entities creating and inhabiting
that new order will not be humans as we know them. Instead,
the majority will be posthumans of some form or other, perhaps
human-machine hybrids, bio-engineered chimeras, redundant virtual
superintelligences, or something else we can't even imagine."

Nanotechnology is Enabling Solar Energy
Sandy55 Blog at AzCentral.com is all about environmental issues. On 11 June 2008, Sandy posted an item titled: "Sun Devils look to the sun for power." Her posting generated one comment that in turn prompted me to post the following comment. posted by Gerald9588 on Jun 12, 2008 at 06:42 AM Bob8930 wrote: "much more expensive energy." True statement today, but advances in nanotechnology leads me to agree with Ray Kurzweil's assessment: "Solar power will be cost-competitive with fossil fuels in just five years, and that within 20 years all our energy will come from clean sources." I agree with Bob that college students are paying a hefty price for their futures. AzCentral.com::Blogs::Sandy55::Sun Devils look to the sun for power. [12 June 2008, top] |

Nanotubes Used to Measure Capsaicinoid Levels
Is there a limit as to how many various and sundry applications can be supported via nanotubes?
"Richard Compton and his team at Oxford University, UK,
have developed a sensitive technique to measure the levels
of capsaicinoids, the substances that make chillies hot,
in samples of chilli sauce."
"The capsaicinoids are adsorbed onto multi-walled carbon
nanotube (MWCNT) electrodes. The team measures the current
change as the capsaicinoids are oxidised by an electrochemical
reaction, and this reading can be translated into Scoville units."

Keep an Eye on CNSE at Albany.Edu
Nanoeconomics is basically the economics of nanotechnology. In a nutshell, how is money made in nanoworld. Kudos to the University of Albany in New York.
"Officials at the University at Albany's College of Nanoscale
Science and Engineering [CNSE] will award what they say is
the world's first degree in nanoeconomics Saturday [17 May 2008]."
"Erez Golan, a 39-year-old graduate student, is scheduled to
receive a Ph.D. in nanoscale science, with a concentration
in nanoeconomics, at ceremonies at the UAlbany campus. It
took him three and a half years to complete."
According to its homepage, CNSE's Albany NanoTech Complex is "$4.2 billion megaplex that has attracted over 250 global corporate partners and it is the most advanced research complex at any university in the world." CNSE.Albany.edu:: College of Nanoscale Science and Engineering [19 May 2008, top] |

Purdue Nanowires an "Active Matrix" Display
Using nanowires to create electronic paper, flexible color monitors, etc.--the applications are endless.
"Engineers have created the first 'active matrix' display
using a new class of transparent transistors and circuits,
a step toward realizing applications such as e-paper,
flexible color monitors and 'heads-up' displays in
car windshields."
"The transistors are made of 'nanowires,' tiny cylindrical
structures that are assembled on glass or thin films of
flexible plastic. The researchers used nanowires as small
as 20 nanometers - a thousand times thinner than a human
hair - to create a display containing organic light emitting
diodes, or OLEDS. The OLEDS are devices that rival the
brightness of conventional pixels in flat-panel television
sets, computer monitors and displays in consumer electronics."

Nanosolar Continues To Attract Investors
This posting was carried over from last month.
"Nanosolar, a privately held solar energy company whose backers
include Google Inc's co-founders, said it has started to sell
what it calls the world's lowest cost solar panel."
"We have begun shipping panels for freefield deployment in
Eastern Germany," said Chief Executive Martin Roscheisen
in a statement on Nanosolar's Web site. "The first megawatt
of our panels will go into a power plant installation there."
Nanosolar uses a "thin-film technology" that requires a small fraction of the "amount of silicon needed in conventional solar cells" and their "technique allows them to make panels profitably for less than $1 per watt." Fast forward to 2 April 2008... Nanosolar announced they received an investment of $50 million from French renewable energy group EDF Energies Nouvelles. [02 April 2008, top] |

Quantum Dots Are Mighty Small Dots
Kudos to Spire Corporation on being "awarded United States Patent Number 7,306,963 entitled 'Precision Synthesis of Quantum Dot Nanostructures for Fluorescent and Optoelectronic Devices.'
"This patent describes a method for designing and synthesizing
quantum dot nanoparticles with improved uniformity and size.
These quantum dots have the potential to create new high
efficiency, low-cost solar cells and other optoelectronic
devices such as lasers, light emitting diodes (LEDs), and
photodetectors. The extremely small size of these structures
also makes them useful for medical assays, diagnostic systems,
and therapeutic compounds." [source: Spire press release]
On 6 March 2008, Scottsdale Community College had a noon-time lecture about quantum dots.
"Quantum dots are nanometer-sized (about one 25-millionth of
an inch) semiconductor structures which, when exposed to light
at predetermined wavelengths, can generate free electrons and
create an electrical current. The confinement of electrons in
these minute three-dimensional structures gives scientists the
ability to use quantum dots to precisely control the optical
properties of various devices, such as a solar cell or a biomarker
for detecting cancer." [source: Spire press release]
I'm betting the following is true: "nanoscience and nanotechnology will change the nature of almost every human-made object in the next century." Or as SCC's Dr. Kyle Rawlings said in his quantum dot lecture--think "synthetic chemistry." LLNL.gov:: Mighty Small Dots [11 March 2008, top] |

Producing Sheets of Carbon Nanotubes
Talk about strength... sheets of carbon nanotubes.
"A New Hampshire company, Nanocomp Technologies of Concord, is
producing sheets of carbon nanotubes that measure three feet
by six feet and promising slabs 100 square feet in area as
soon as this summer."
"The sheets, which the company can produce on its single machine
at a rate of one per day, are composed of a series of nanotubes
each about a millimeter long, overlapping each other randomly to
form a thin mat. The tensile strength of the mat ranges from 200
to 500 megapascals--a measure of how tough it is to break. A sheet
of aluminum of equivalent thickness, for comparison, has a strength
of 500 megapascals. If Nanocomp takes further steps to align the
nanotubes, the strength jumps to 1,200 megapascals.

Wiper-Less Windshields?
The windshield wipers on my car don't like it if the window isn't really wet. In addition, they like to leave streaks as they move across the window. I'm looking forward to using nano-dust on my glasses to keep them clean and scratch-free (heck, someday I'll probably won't need glasses).

Using Nanowires In Clothing
I thought my nano-treated pants were cool, but having pants (and other items of clothing) that can generate energy will be even cooler.
"Scientists in the US have developed novel brush-like
fibres that generate electrical energy from movement."
"Weaving them into a material could allow designers to
create 'smart' clothes which harness body movement to
power portable electronic gadgets.'
"Writing in the journal Nature, the team say that the
materials could also be used in tents or other structures
to harness wind energy."
There has always been speculation that we'll be wearing intelligent clothing and this is simply an extension of that speculation. BBC.co.uk:: Nanowires allow 'power dressing' [14 February 2008, top] |

Nanotechnology Basics for Students
Scottsdale Community College is attempting to put on a 1-credit "Survey of Nanotechnology" course. This is not an easy task and picking a good starting point is important. The Nanotech SmallBlog likes the resources provided by the Center for Responsible Nanotechnology.
"The principles of physics, as far as I can see, do not speak
against the possibility of maneuvering things atom by atom.
It is not an attempt to violate any laws; it is something,
in principle, that can be done; but in practice, it has not
been done because we are too big."--Richard Feynman

Nanotechnology Helping Advance Biomimetics
Biomimetics has to do with developing computer technology that will be able to learn, adapt to change, and protect and repair itself.
"The advent of computer modeling capabilities and the arrival
of nanotechnology allow us to interrogate the wisdom that
nature displays."--John Pietrzyk, founder Biomimetic Connections
Biomimetics example: An algorithm that optimizes Internet servers is based on honeybee colonies. The following quote comes from Julian Vincent, director of the Center for Biomimetic and Natural Technologies at the University of Bath in England.
"We should understand the way biology does its engineering and
then replace current engineering with the biological version."
