SYDNEY: Nanotech experts are more concerned than the public about the potential health and environmental risks of the technology, says a new survey. So should we be worried?
Detailed in the journal Nature Nanotechnology the study suggests the public are still largely in the dark over the potentially huge benefits and risks of the diminutive new science.
"Nanotechnology is starting to emerge on the policy agenda, but with the public, it's not on their radar," said study co-author Dietram Scheufele, a professor of life sciences communication and journalism at the University of Wisconsin-Madison, USA.
Despite acknowledging the risks, scientists surveyed believe their work will lead to major breakthroughs in medicine, environmental cleanup and military technology. By addressing any risks before the technology widely enters the public domain, the experts hope to avoid a backlash in public opinion that has been seen in other emerging technologies such as genetically modified food.
Micro machines
Nanotechnology is a promising area of applied science that draws from diverse fields including physics, chemistry and biology. The common theme that connects these threads is the manipulation of matter on a molecular scale. The fruits of nanotechnology don't exceed 100 nanometres in size, which is only one thousandth the breadth of a human hair. DNA, for example, is two nanometres wide and carbon nanotubes can be half that size in diameter.
Hundreds of consumer products already contain nanomaterials, most of which are cosmetics, sunscreens and cleaning products with microscopic particles. But this is the only first step in what promoters of nanotech say will be a technological revolution.
Nanomaterials lighter and stronger than those used today could revolutionise the car and aeroplane industries, and similar technologies are being developed in the fields of robotics, computers, clothing, energy storage and air purification. Medical scientists are investigating the possible uses of nanotechnology in treating cancer and other diseases. It is hoped that nanoparticles could specifically target and deliver drugs to cancerous cells.
Futurists imagine a world where sub-microscopic 'nanobots' repair damaged tissue or eliminate harmful pollutants from the environment. The idea of building molecular machines was first raised in the 1950's by U.S. physicist Richard Feynman who coined the term 'nanotechnology' – but if such advanced engineering is possible, it remains a long way off.
Risky business
To learn more about the perception of risks and benefits associated with the technology Scheufele and Elizabeth Corley of Arizona State University in Phoenix surveyed around 1,000 members of the public and 363 nanotech scientists. Their findings reveal a disparity between the perceptions of scientists and the general public on the potential risks and benefits of nanotechnology.
The potential of nanoparticles to harm human health was found to be more of a worry to scientists than the general public.
The report draws attention to the existing debate within the scientific community about a lack of systematic research into the risks of nanotechnology. According to researchers, our current knowledge of the toxicology of nanoparticles is limited. There is a fear that the particles may have detrimental effects on the lungs, for example, if they are inhaled.
"We are realising that the standard regulations aren't necessarily appropriate for nanotechnology," said Peter Binks, the chief executive officer of Nanotechnology Victoria, a promotion and commercialisation body at Monash University in Melbourne, Australia. He highlighted the fact that current toxicology regulations relate to the mass of a dose – but in the case of nanoparticles, the surface area may be more important.
The report concluded that the public believe scientists to be a more trustworthy source of nanotechnology information than regulatory agencies and governmental bodies. "We found communication gaps, but also tremendous opportunities for scientists to close them" said Scheufele. "There is definitely a huge opportunity for scientists to communicate with a public who trusts them."
"This is a terrific report and really highlights that the debate is becoming more sophisticated," commented Binks. "In Australia, we are well positioned to participate in that debate."

The Future of Nanomaterials
The DC-based research and consulting firm Social Technologies recently released a series of 12 briefs that shed light on the top areas for technology innovation through 2025. The brief on "nanomaterials," by futurist Peter von Stackelberg, is the fourth trend in the series.
"In the next 10 to 20 years, we'll see major breakthroughs in nanomaterials and related processes used to produce many of our consumer and industrial products," von Stackelberg forecasts. Here's why.
Technology overview Small is the key word that describes the world of nanotechnology. The concept centers on miniaturization, and involves the creation of particles, fibers, films, coatings, and other materials that are significantly smaller than the typical bacterium—between one and 100 nanometers in size.
Because these particles are so tiny, nano-objects can access previously impenetrable areas. That means they can make consumer products lighter, stronger, and more efficient—creating a significant competitive advantage for the companies incorporating them into their goods. In an era when consumers are demanding products that are more effective, protective, and assistive, nanomaterials provide the perfect fit.
Industries and consumers are also demanding more efficient use of resources and fewer waste streams. Again, nanomaterials fit the bill. Additionally, rising energy costs and the insecurity of petroleum supplies are driving research into nanomaterials that can boost production from alternative sources, or cut demand via greater energy efficiency.
Challenges ahead
As nanotech emerges as a major technological force over the coming decades, it will face a variety of obstacles. These include:
Mastering nanoscale behavior. To date, the potential interactions of nanoscale matter are not understood, von Stackelberg explains. "As research progresses, we may find that nanomaterials do not act as expected, leading to unanticipated and potentially harmful consequences. Once understanding improves about how matter behaves at the nanoscale, researchers will be able to develop increasingly sophisticated applications of nanotech while avoiding human side effects."
Public fears. The perception of the benefits vs. hazards of nanotech will have a significant impact on consumer acceptance of the technology. "A survey conducted in 2006 showed that although 42% of those polled had no awareness of nanotech, 20% had heard a little about it and 11% were quite familiar with it," von Stackelberg says—noting that the majority of those in the know believed that the risks of nanotech outweigh the benefits (35%). Only 15% said they believe the benefits outweigh the risks, and 7% said the benefits and risks are about equal.
Nanotech risks. "Obviously, a rational assessment of the true risks of nanotechnology are needed to ensure that wildcards like ‘grey goo' don't dominate the discussions of risk while other, more realistic risks are ignored," he points out. The potential for severe risk have been identified by the Center for Responsible Nanotechnology, and include:
Health and environmental risks. A growing body of scientific evidence reports that nanomaterials have the potential to pollute air, soil, and water and to damage human health. Some of the most interesting properties of nanomaterials—such as the ability of nanoparticles to penetrate human cells—also present health risks if these particles escape into the environment, where they can be absorbed into people's bodies. "Our understanding of the potential health and environmental implications of nanotech are extremely limited," adds von Stackelberg.
Proliferation of "nanolitter." As more sophisticated nanomaterials become widely used, nano-byproducts will need to be dealt with. For instance, it isn't currently known whether nanoparticles used to treat cancer can remain in a patient's body or be excreted. "The reality is that nanomaterials which are useful and benign in one setting can actually be harmful in another," von Stackelberg explains.
Criminal or terrorist use. Small, powerful weapons made from nanomaterials would be difficult for society to defend against.
Forecasts
Although the underlying concepts of nanotechnology were thought up in 1959, only during the 1990s were the first tentative steps taken toward identifying and developing nanomaterials. "Between the end of the first decade of the 21st century and 2025, a number of gamechangers will need to occur if nanotech is to advance significantly," von Stackelberg says. These gamechangers include:
A shift from "passive" to "active" nanotech. In the coming decades, nanotech will likely make the transition from simple nanomachines—particles, crystals, rods, tubes, and sheets of atoms—to more complex ones that contain valves, switches, pumps, and motors.
Nanoscale tools. To work at the nanoscale, new tools will be needed to allow researchers and technicians to see, measure, and manipulate individual atoms and molecules. "One promising approach uses dynamic light scattering, a technique that measures how much nanoparticles jiggle when hit with laser light," von Stackelberg shares. "Many scientists agree that this method has the potential to do rapid, accurate measurement, and is expected to be operational by 2010."
Nanofabrication. Currently, manufacturing processes for nanomaterials are extremely expensive, produce only small amounts of material, and generate a significant amount of impurities and waste, von Stackelberg says. "But consider this: Assembly of nanodevices today is at the same stage as the automobile industry was before Henry Ford developed the assembly line."

Organization for the Economic Cooperation and Development Student Rankings
by Michael Orshan
What do exactly do with our taxes? Do we spend in on the advancement of science and technology? How about education? Ha! How about, I don’t know what else? Besides war and basic operations, I can’t figure out what the US government does for the advancement of society. Once upon a time we lead the world in so much.
Check out the student assessment study recently released. Korea. Oh my god, Korea is having so much success in education they should franchise whatever they are doing. Or Finland, who is having an equally phenomenal success story. I hope that someone on this side of the world is checking these programs out.
So what’s the news? I’ve checked several times now and on the reading scale, the United States is not on the chart. Who is preventing them from showing up besides the top dogs? Well the bottom three is Azerbaijan, Qatar and Kyrgyzstan.

IBM Demos New Nanotechnology Method to Build Chip Components
ARMONK, N.Y.–(BUSINESS WIRE)–Dec. 8, 2003–
IBM today announced it is the first to successfully apply a novel approach in nanotechnology to aid conventional semiconductor processing, potentially enabling continued device miniaturization and chip performance improvements. IBM used a “molecular self assembly” technique that is compatible with existing chip-making tools, making it attractive for applications in future microelectronics technologies because it avoids the high cost of tooling changes and the risks associated with major process changes.
IBM’s self-assembly technique leverages the tendency of certain types of polymer molecules to organize themselves. The polymer molecules pattern critical device features that are smaller, denser, more precise, and more uniform than can be achieved using conventional methods like lithography. The use of techniques such as self assembly could ultimately lead to more powerful electronic devices such as microprocessors used in the growing array of computer systems, communications devices, and consumer electronics. IBM expects self-assembly techniques could be used in pilot phases 3-5 years from now.
“Self assembly opens up new opportunities for patterning at dimensions smaller than those in current technologies,” said Dr. T.C. Chen, vice president of science and technology at IBM Research. “As components in information technology products continue to shrink toward the molecular scale, self-assembly techniques could be used to enhance lithographic methods.”
Nanotechnology is a broad field of science in which materials are manipulated at dimensions which approach the size of individual atoms or molecules. Self assembly is a subset of nanotech that refers to the natural tendency of certain individual elements to arrange themselves into regular nanoscale patterns.
In this instance, IBM researchers used self assembly to form critical features of a semiconductor memory device. The polymer patterns the formation of a dense silicon nanocrystal array which becomes the basis for a variant of conventional FLASH memory. Nanocrystal memories are difficult to fabricate using conventional methods; by using self-assembly, IBM has discovered a much easier method to build conventional semiconductor devices such as FLASH memories. Device processing, including self assembly, was performed on 200 mm diameter silicon wafers using methods fully compatible with existing chip-making tools.
This nanotechnology breakthrough is reported in a paper entitled “Low Voltage, Scalable Nanocrystal FLASH Memory Fabricated by Templated Self Assembly” by K.W. Guarini, C.T. Black, Y. Zhang, I.V. Babich, E.M. Sikorski and L.M. Gignac will be presented by IBM tomorrow at the IEEE International Electron Devices Meeting (IEDM) in Washington, D.C. Continuing its leadership in technology innovation, IBM is presenting 19 papers at IEDM this year, more than any other company.

Building on over a decade of Worlds firsts in pure-CMOS, this new family of 2.5Gb and 10Gb TIAs offers at least 3-4dB more Sensitivity at each data rate Vs. the best existing solutions, which are typically in expensive SiGe processes.
The NT25L55 offers –33dBm typically at 2.5Gbps, with a standard PIN diode, and with only 33mA current consumption. The NT25L55 can therefore be used to replace APD based solutions in GPON networks, offering dramatic cost and power savings.
The NT28L50 and NT28L51 offer –25dBm typically at 10Gbps, again with only 33mA consumption. The NT28L50 is intended for upcoming SFP+ modules, while the NT28L51 is tailored to LRM applications. Both ICs are believed to offer not only by far the highest performance in the world, but also are the World’s first CMOS 10Gbps TIAs.
All ICs require a single 3.3v supply, and are pin-compatible with previous products. On-chip filtering means no capacitors are required inside the ROSA, offering both Bill-of-Materials cost reduction and faster, lower cost assembly. Photodiode Monitor source/sink and output polarity are both bond-programmable, offering complete build flexibility.
'Alpha' customers are being sought now, with production ramp-up expected early in 2008.
Dr. Ya Nong Ning, Marketing Director for GOF products, added: "Manufactured in standard 0.13u CMOS, at the world’s largest wafer foundry, this new family of ICs offers customers exactly what they need in terms of reliability, short manufacturing lead-times, and CMOS pricing, in addition to the best performance ever seen."
Gary Steele, CEO, commented: "One of the most interesting things about this latest architectural breakthrough is that it builds upon the Company’s earlier solutions to the challenges in the Plastic Optical Fiber (POF) world. Not only does this new architecture offer both higher sensitivity and lower power, but it is also extremely forgiving of it’s opto-electrical and mechanical environment, something the Consumer- and Auto-orientated POF world takes for granted, but that is relatively new to the Glass fiber world."
Contact Nanotech for details of the Alpha customer program, datasheets & applications support materials. Alpha customers will also have early access to important additional novel features, under NDA.

Nano Titanate Batteries May Resurrect the Electric Car
In January 2007, a member of our Design News staff claimed responsibility for a murder; see “I Killed the Electric Car” by Chuck Murray. Chuck’s article presented simple calculations to illustrate that for standard American drivers, conventional electric cars make no sense due to long charge time and low mileage-per-charge. Nonetheless, Chuck elicited some angry reader feedback including a post, “What about the Chevy Volt, Chuck!?”, by our Editor-In-Chief, John Dodge, who apparently likes to wait 6 hours every time he needs to fuel his car.
After almost a year of staring one another down from their respective cubicles and periodically firing ethanol and bio-diesel spitballs at each other across the office, Chuck and John can finally put their debate to rest.
Advances in battery technology originally aimed at lap top computers piggybacked atop zero-emission vehicle regulations established to entice development of hydrogen fuel cell vehicles may be breathing new life into the electric car.
“Who’s Resurrecting the Electric Car?” by David Schneider appeared in the October edition of American Scientist Magazine. According to this article, lithium-ion batteries first used in lap top computers are now being successfully integrated into street-legal cars such as the high-end Roadster by Tesla Motors. Powered by computer batteries, this car boasts the performance, speed, and range of its gas-fired sports car cousins. While consumers may need to take out a second mortgage to buy a Tesla Roadster (base price $98,000 before upgrades), the company has already filled all available reservations for the 2008 model year, and they will soon be taking orders for their 2009 model. While a cursory search failed to reveal any data on this company’s financial viability, Tesla’s growing product wait list seems to denote a company in no danger of going under.
When Chuck Murray killed the electric car in January 2007, his calculations considered the time required to traverse various distances in excess of the EV1's 70- to 100-mile-per-charge range. Key to this analysis was the inconvenient five-hour charge time associated with lead-acid or nickel-metal-hydride batteries. With four charge stops at five hours per stop between Chicago and Detroit, Chuck’s regular 5-hour jaunt increased to a 25 hour exercise in patience.
To eliminate long charge times, the new generation of electric vehicles will be powered by lithium-based batteries related to the cells used to power laptops, but with a twist. Historically, the challenge with scaling-up lithium batteries was their tendency to release oxygen if they overheated, causing fires and explosions. However, by switching the battery’s carbon chemistry for titante nano-particles, the fire hazard is eliminated. Although this switch reduces energy density with respect to carbon-based lithium-ion batteries, it enables scale-up of lithium technology competent for safe use in electric cars.
Nano-titanate-based lithium batteries have greater energy density than the lead-acid or nickel-metal-hydride batteries of the old EV1. Plus, they have an even more desirable attribute: the ability to recharge in about 10 minutes as opposed to hours. For rapid charging, the Altairnano lithium titanate battery is the leading power source for automotive applications. The uncanny 10-minute recharge time is enabled by nano-materials that dramatically reduce ion travel distance while increasing the surface area available to the ions.
Another startup electric car manufacturer, Phoenix Motorcars, is using this new battery technology in their zero-emission fleet vehicles. Rapid recharge time and 100+ mile range may qualify vehicles from Phoenix Motorcars for the highest zero emission vehicle category established by the California Air Resources Board. This category, originally slated for hydrogen fuel cell vehicles, may provide Phoenix substantial credit for each vehicle they put on the road.
Driving a Phoenix automobile powered by Altairnano batteries, even Chuck Murray, the great murder of electric vehicles, could comfortably get from Chicago to Detroit in about 5 hours and 30 minutes without burning a drop of gasoline. John Dodge could make it in 5.5 hours too, if he was willing to give up those six-hour pit stops.
