Countries
around the world have followed the lead of our nation in making
investment in nanotechnology a national priority. In human history,
whenever a fundamentally new type of material emerged, a new economy
was born. This certainly happened during the Stone, Iron, Bronze, and
Plastic Ages. Instead of pertaining to a single material,
nanotechnology provides the opportunity to so fundamentally change
virtually any material that a groundswell of new businesses will arise.
Those
countries and companies that do not lead in the development and
application of nanotechnology are at great risk of becoming
noncompetitive. Recent avalanching advances in the ability to
manipulate materials at the sub-microscopic scale means that the
materials of the future can have properties that were only imagined in
the past. Taking an example from biology, nature has long been
manipulating virus and cells at the submicroscopic level. This ability
of nature to operate at a very small scale eventually cascaded to the
diverse functionality of higher organisms. However, it took
approximately 600 million years after the formation of the Earth for
nature to achieve the single cell, and less than a million years
afterwards to develop the first organism.
Materials
made possible by nanotechnology will include those having some of the
capabilities of biological systems, like the ability to appropriately
change properties in response to the environment and to self-repair.
This vision of taking nature’s nanosize building blocks to build
manmade materials, first proposed by the legendary Richard Feynman some
44 years ago, is the fundamental guiding principle of this now
exploding field of nanotechnology.
Overview of the Nano-Tech Institute at The University of Texas at Dallas
The
NanoTech Institute of The University of Texas at Dallas was founded
merely two years ago. We did this by strategically hiring some of the
best people in the world to propel our activities in this arena. The
Institute is led by its Director, Dr. Ray Baughman, its Deputy
Director, Dr. Anvar Zakhidov, and Dr. Alan MacDiarmid, a Nobel laureate
in Chemistry in 2000 and holder of the James Von Ehr Distinguished
Chair in Science and Technology. I am extremely pleased to say that by
working as a team, which includes senior management of UTD, the various
Schools within the university, and the technological and economic
planning communities in North Texas, the Institute has grown rapidly to include more than 60 people from all over the world.
We
are inspiring and educating students of all ages for the work force and
creating knowledge and technologies that will generate new businesses
and job growth. Physicists, chemists, biologists, ceramicists,
metallurgists, and mathematicians are teaming with engineers to solve
problems. We are eliminating boundaries that interfere with the
transition from science to technology, and from technology to product.
The NanoTech Institute has an atmosphere of excitement, fun, and
creativity that inspires – researchers from 8th graders to senior citizens work in our laboratories in the quest for new basic understanding and new technologies.
Finding
and effectively utilizing new energy sources without damaging the
environment is one of the primary challenges of our Nation and the
World. For this reason, the Nanotech Institute has identified
NanoEnergetics as an area of focus. We are using carbon nanotube fibers
for the
(a) Transformation of electrical energy to mechanical energy in nanotube artificial muscles,
(b) Reversible transformation of electrical energy to chemical energy in supercapacitor and battery fibers that can be woven into electronic textiles,
(c) Transformation of mechanical energy to elastic energy and thermal energy in super-tough carbon nanotube composite fibers, and
(d) Transformation of waste thermal energy into electrical energy in electrochemical thermal energy harvesting devices.
While
every category deserves a full and detailed description, within the
time constraint, I will merely underscore that one important aspect is
the assembly of nanofibers into high performance fibers that can be
used in building devices. All known bulk synthesis methods produce
carbon single walled nanotubes as impure soot. An important challenge
is to develop practical technologies for transforming this soot into
continuous fibers that have useful properties for important
applications, such as converting waste thermal and mechanical energy to
electricity, mechanical energy absorption in safety harnesses, and
energy storage in textiles for the soldier.
By
using a novel spinning apparatus, spinning solutions, and spinning
coagulants, the scientists in UTD’s NanoTech Institute have spun
nanotube fibers with record lengths, tensile strengths, and
energy-to-break (toughness). No known fibers of any type are nearly as
tough. The landmark importance of the advance (published in Nature and reported in Science)
was indicated by news coverage from around the world (Wall Street
Journal, New York Times, US Today, China Peoples Daily, Discover
Magazine, NBC and ABC television, Voice of America, Science, Physics Today, C&E News, etc.).
In
the late seventies, I was privileged to spend a year as a visiting
professor in the Niels Bohr Institute in University of Copenhagen, then
one of the world centers of nuclear science research. At the NBI, led
by the two Nobel laureates, there was great scientific excitement
there, and great works and discoveries were performed routinely by
scientists from all over the world. It was quite an intellectual
atmosphere. I am therefore extremely pleased to observe a similar
intensity of intellectual excitement about a new and fast paced field
of science and technology, permeating in UTD’s NanoTech Institute.
Questions and Responses
How significant of an impact will nanotechnology have on U.S. economic growth and job creation in the coming decades? In what industry areas will the impact be most dramatic? What challenges exist that may slow or limit the growth and influence of nanotechnology?
In
the long term, I believe that most products will depend upon
nanotechnology, from products for detecting and treating cancer, to
smaller and faster computers, to improved sensors for home land
security, and to the skins of our most advanced aircraft. Anytime
fundamentally new materials with exciting properties are created, new
businesses can result. Nanotechnology is generic, avalanching abilities
in manipulating and self-assembling of the nanoscale are creating
fundamentally new materials of all kinds – from metals, semiconductors,
and superconductors to plastics. An economy base on new materials and
devices can simply mean to carry out traditional tasks more
efficiently, or more often then not, carry out tasks which were
previously impossible. Also, it can mean having materials that are
multifunctional, like nanotube fibers fabricated at UTD’s NanoTech
Institute, which might eventually be used in a soldier’s uniform as
both a power source and for antiballistic protection.
Nanotechnology
can also provide intelligent materials, like the NanoTech Institutes
nanotube sheets, which can detect the composition of the fuel mixture
in an engine and automatically open or close a valve – all without the
need for an external power source. Mr. Chairman, advances in
nanotechnology will likely impact virtually all industries, from
materials, clothing, aerospace, communications, biotechnology, and
computing industries to industries that not yet even been conceived. As
for any new area, there are a host of challenges that must be solved.
One is the high cost of producing materials on laboratory scales.
Materials producers are wary of risking money on improving and
upscaling material production until customers are clearly identified,
and users are wary of investing money on evaluating the materials in
their products until they can be guaranteed low material cost.
Cradle-grave assurance of material and product safety is another
important issue for nanotechnology-based materials, but probably no
more than for other materials and chemicals.
What
in your experience are the best practices to help facilitate the
transfer of basic research results to industry? To what extent has the
Institute partnered with industry on nanotechnology research and
development challenges, and how can such collaborations be made more
effective?
The
evolution of nanotechnology advances into new economies is still at the
early phase, but there are already noteworthy successes, like the
commercialization of remarkable biomedical test kits, multiwalled
nanotubes as conducting additives for plastics, and nanofiber coated
textiles for ordinary clothing (jeans). Overcoming the barriers between
early technological breakthroughs and products is always challenging,
and targeted governmental funding can make the difference between a
shelved technology and a commercial success. Two years ago, at a
nanotechnology conference in Richardson, Texas, Jack Kilby, one of the
scientific giants of the 20th century from Texas Instruments
and the year 2000 Nobel laureate for discovering the integrated circuit
(IC) said that, and I paraphrase, “if it was not from the military, the
IC may still be on the shelf today.” In a sense, the discoveries of
nanotechnology are similar to the IC discoveries in the early days.
Achieving commercial application may or may not be straightforward,
depending upon the technology. The best practice is for universities to
partner early on with the most appropriate companies. Throwing early
technology results over a fence to industry generally doesn’t work, so
finding ways to facilitate the partnering of industry and universities
is critical.
UTD
is partnering with a host of companies in the area of flexible
light-emitting displays, and is partnering with industry on federally
funded work in the nanotube area.
Has
federal support for your research been effective at helping the
Institute achieve its goals? How might Congress strengthen the
structure, funding levels, and focus of the National Nanotechnology
Initiative?
The
successes achieved by UTD’s NanoTech Institute research programs would
not have existed were it not for the support of various Federal
agencies as well as the visionary leadership of statesmen such as you.
The same is true for virtually all of the major nanotechnology efforts
in universities that are ongoing in our country today. Continuation and
strengthening of this support is critical for our nations maintaining
and increasing its leadership position. Industrial managers, especially
in large companies, are often forced to focus on next year’s product,
so that the research commitment to revolutionary products is severely
weakened. Targeted funding like that of the NIST ATP program can help
industry take risks that are in the longer term interest of our economy
and the companies, and facilitate partnering between industry and
universities.
Programs
for small businesses, like the SBIR program, are critical, and
increases in phase I funding levels could provide the industrial focus
that enables success.
Is
the U.S. education system currently producing an adequate number of
people with the skills needed to conduct research in nanotechnology and
to work in industry on the commercialization of nanotechnology
applications? What is the longer-term outlook for the nanotechnology
workforce, and what changes, if any, should be made to the current
education system to ensure these workforce needs are met?
I
do not think I am exaggerating that many of our research universities
are among the best in the world. However, the number of Americans
obtaining PhDs has not grown with our population and with the
increasing needs of our industry. Indeed, our Nation’s intellectual and
economic growth has long been closely linked to our ability to absorb
the best and the brightest from all corners of the globe. Innovations
carried out in American university laboratories are powered by
students, postdocs, and faculty members from across the United States
and from all regions of the Earth, and many of these individuals join
American industry to forge the products of the future. The NanoTech
Institute of UTD is but a microcosm of this trend. For example, in the
NanoTech Institute’s laboratories, you will find nearly around the
clock, American students, postdocs and faculty members working
hand-in-hand with their colleagues from Russia, Uzbekistan, China,
Korea, Philippines, Brazil, India, Germany, Ireland, Spain, Australia,
and other countries. Mr. Chairman, in the wake of The War on Terror, a
situation has arisen because of the serious limitation of visas issued
in countries that are becoming the world’s technical powers.
At
the most obvious level, the ability of international scientists to
attend scientific conferences in the United States has become
problematic. Often even invited speakers are unable to receive a visa
in time. Unless this visa problem is corrected, I fear that major
international conferences will be rarely held in our country, so our
students, technologists, and industries will lose rapid access to
information. The brain drain of the past has been to enrich America,
and I fear that present visa crisis is now closing our borders to many
of the best and brightest from around the word. We are in danger of no
longer being a "technology" melting pot.
At
the same time as we are seriously restricting visas for these
countries, important American companies are creating major research
laboratories in China and India. Business is usually done with those
you know, often through face-to-face interactions, and I further fear
that the visa problem will eventually decrease our ability to conduct
commercial interactions with rapidly developing economies around the
world.
Mr.
Chairman, the visa issue is beginning to effectively isolate American
science and technology and decrease our ability to attract the
brightest and most productive scientists to our shores. Unless,
solutions are found we could be jeopardizing both our economic progress
and security built on leadership in nanotechnology and many other
fields.
In
the final analysis, the chronic shortage of scientists and engineers
facing our Nation require long term and sustainable solution by the
Federal Government. There is no replacement other then to truly excite
our students in the K-12 levels in science and mathematics, and the
only way we can achieve that is to greatly enhance the number of
skilled teachers at those levels.
In
summary, nanotechnology is a fast changing field. I think everyone
would agree with me that not so long ago, North Texas was not known for
its nanotechnology efforts. Now, we are on the national and
international radar screen. Your assistance and understanding of all
the issues surrounding the region’s ability to maintain a healthy
scientific and economic landscape will be critical to our future.
