Foresight Nanotechnology Challenges

Foresight has articulated six critical challenges that humanity faces which can be addressed by nanotechnology. In the Weekly News Digest we identify news items, research breakthroughs, and events citing current research and applications providing the stepping stones to solutions to these challenges.

1. Meeting global energy needs with clean solutions

Foresight note: According to researchers at NIST, tethering hydrogen in stacked nanocages might lead to an alternative to fossil fuels.

Headline: Scientists report progress with hydrogen fuel nanocages
News source: SmallTimes

A strategy to stack more hydrogen in nanoscale, zinc-based box scaffoldings may ultimately help replace fossil fuels in vehicles, U.S. scientists report. Researchers at the National Institute of Standards and Technology used beams of neutrons as probes to determine where hydrogen latches onto the lattice-like arrangement of zinc and oxygen clusters in a custom-made material known as a metal-organic framework.

2. Providing abundant clean water globally

Foresight note: This corporate webpage has a clear definition of nanofiltration in context with ceramics.

Headline: New ceramic nanofiltration membranes
News source: Lenntech Corporate Website

"The nanofiltration technique is mainly used for the removal of two valued ions and the larger mono valued ions like heavy metals. This technique can be seen as a coarse RO (reversed osmosis) membrane. Because nanofiltration uses less fine membranes, the feed pressure of the NF system is generally lower compared to RO systems. Also the fouling rate is lower compared to RO systems."

3. Increasing the health and longevity of human life

Foresight note: Nanotechnology has the potential to improve diagnosis, imaging and early detection. This article discusses quantum dots sensing DNA without fluorescence.

Headline: Quantum dots to sense DNA
News source: Nature Materials and Eurekalert

Sensing DNA directly in a solution and without having to go through tedious separation and amplification procedures is a great challenge in molecular biology. The results of these analyses are critical for diagnosing genetic diseases. Chun-Yang Zhang and colleagues at John Hopkins University now present a straightforward and sensitive method that, being based on the fluorescence emission from quantum dots rather than from molecular probes, circumvents the infamous problem of background fluorescence.

"Conventional methods of finding and identifying samples of DNA are cumbersome and time-consuming," said Jeff Tza-Huei Wang, senior author of the paper published in Nature and supervisor of the research team. "This new technique is ultrasensitive, quick and relatively simple. It can be used to look for a particular part of a DNA sequence, as well as for genetic defects and mutations."

4. Maximizing the productivity of agriculture

Foresight note: This article discusses a UK report being conducted that will address public concerns about nanotech. There is a large food and agriculture component in this study's current scope.

Headline: UK nanotechnology research directed at food industry
News source: Food Production Daily by Ahmed ElAmin

UK research will be directed to studying the potential risks posed by nanotechnology, including its effects on health from its use by the food industry, according to a report released yesterday.

The report is a forerunner to eventual regulation on nanotechnology and is meant to address public concerns over the emerging science, which is already being as used by the food industry. While far reaching visions such as nanotech food synthesizers or pathogen killing nanobots are not expected to become reality within the next decades, nanotechnology related research and development projects for food processing, food engineering and food packaging are currently in the innovation pipeline.

5. Making powerful information technology available everywhere

Foresight note: Here is an instance of two large companies, AMD and IBM, collaborating on the nanoscale for improved semiconductor and processing power.

Headline: AMD, IBM Unveil New, Higher Performance, More Power Efficient 65nm Process Technologies
News source: Physorg.com

In papers presented at the International Electron Devices Meeting (IEDM) in Washington, D.C., IBM and AMD detailed their progress in bringing new, advanced semiconductor process technologies and materials to the 65 nanometer technology generation.

The companies announced that they have successfully combined embedded Silicon Germanium (e-SiGe) with Dual Stress Liner (DSL) and Stress Memorization technology (SMT) on Silicon-On-Insulator (SOI) wafers, resulting in a 40 percent increase in transistor performance compared to similar chips produced without stress technology, while controlling power consumption and heat dissipation.

"Our joint work on developing advanced process technologies continues to ensure we can create and provide the highest performance, lowest power processors on the market," said Nick Kepler, vice president of logic technology development at AMD.

6. Enabling the development of space

Foresight note: This article discusses how carbon nanotubes can be arrayed to lower the cost per payload to launch communication satellites.

Headline: Space saving approach to satellite communications
News source: Physorg.com

Ken Teo and his team at the University of Cambridge have come up with a much more efficient and compact way to send signals from satellites. They have managed to use an array of carbon nanotubes to create a device that replaces conventional heavy, bulky, high temperature, microwave amplifiers. The new electron source promises to revolutionize telecommunications and satellite communications in space.

Long-range communications are a vital part of our lives for business, entertainment or just keeping in contact with friends and family. Much of this, especially to remote areas, is made possible through communications using satellite-based transmitters. There are typically 50 microwave amplifiers on board a satellite, each weighing about 1kg and measuring about 30cm in length.

Currently it costs about 10,000 pounds sterling to send a single kilogram of payload (data) into space. There is an advantage, both in terms of cost savings and extra payload that can be carried, if the weight and size of the microwave devices are reduced.

Headline: Nanotechnology: Big trouble in the mini-revolution?
News Source: The Independent by Jimmy Lee Shreeve

Nanotechnology could treat cancer or create clean energy. But what happens if nano-particles enter our bodies? Jimmy Lee Shreeve reports on the mounting fears.

Nanotechnology has been hailed as a potential cure for cancer and environmental ills. But could it become the asbestos of the 21st century? Researchers and futurists believe that nanotechnology could transform everything from healthcare and manufacturing to environmental clean-up and space travel. Many of the worst problems threatening us, they say, could be eradicated this century.

Cancer cells could be destroyed by tiny silicon combs; "nanobots" could clear blocked blood vessels. Hydrogen-based fuel cells using "nanotubes" could allow cars to travel 5,000 miles on a full tank. Minute solar cells in building facades and on road surfaces would produce cheap energy.

Nanoparticles might detoxify petrochemical waste. There could be a new industrial revolution as atoms are assembled into useful new products. But at scales of a millionth of a millimetrer, materials can develop unusual and unpredictable properties, leading to concerns about risks to health and the environment. Some experts are calling for a moratorium on nanotechnology, saying that ultra-fine particles created for cosmetic, industrial and high-technology uses could prove deadly.

Editor’s Pick

Dear readers — When reviewing news for this digest, I often read about something that I think is cool, but it doesn't fit within the usual editorial categories of the News Digest. This section highlights a nanotech advance or idea that I think is especially cool.

—Judy

Scott E. Rickert, CEO of Nanofilm, Ltd. and a Participating Member of Foresight Nanotech Institute, wrote this opinion piece, "Taking The NanoPulse — Nanotechnology. Good And Green," for IndustryWeek.com. He provides some history of nanomaterials in the environment and gives a view for the future.

I have listed a couple of excellent quotes from Rickert's opinion piece but you really should read the entire article. It has several thought provoking points.

"Nanotechnologists care about the environment, too. We live on this earth, too, drinking the water and breathing the air. And, in fact, most of us have more contact with nanomaterials on a daily basis than anyone in the general public."

"Couldn't we simply slow down the whole expensive process and take a wait- and-see attitude? There is at least one multinational company executive who has publicly stated this to be his approach. There are two reasons why the answer must be no. First, the global economy will continue to push the limits of nanotechnology's possibilities; America can't afford to fall behind. Moreover, and most importantly, nanotechnology holds the potential to unlock advances that replace current environmentally harmful practices with new greener ones."
