Nanotechnology to be Discussed at Outlook Forum

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from USDA’s rich science and research portfolio.

Say it: nanotechnology.

The word alone sounds intriguing, futuristic. But what is nanotechnology?

In simple terms, nanotechnology is understanding and controlling matter on a molecular scale—at dimensions between approximately 1 and 100 nanometers. Read more »

USDA Secretary Vilsack Tours the Forest Products Laboratory

Research Microbiologist Carol Clausen discusses wood durability and protection research with Agriculture Secretary Tom Vilsack during his visit to the Forest Products Laboratory.

Research Microbiologist Carol Clausen discusses wood durability and protection research with Agriculture Secretary Tom Vilsack during his visit to the Forest Products Laboratory.

The Forest Products Laboratory (FPL) recently guided USDA Secretary Tom Vilsack through its unique set of research facilities. Basic and applied research at FPL supports a number of objectives, including forest management and restoration, the wise use of forest resources, job creation, and expanding economic opportunities through public-private partnerships on a national scale.

Throughout his tour, Secretary Vilsack talked with lab leadership about FPL’s diverse and innovative research efforts. Project leaders used the opportunity to field questions from the Secretary and explain work ranging from wood preservation and durability to advances in “green” building strategies and technology, use of beetle-killed trees, work on historic timber bridges, and advances in nanocellulose-related materials and applications.

USDA Under Secretary Sherman Unveils Nanocellulose Production Facility

The U.S. Forest Service Forest Products Laboratory recently opened a $1.7 million production facility for renewable, forest-based nanomaterials.  This facility is the first of its kind in the United States and one that positions the laboratory as the country’s leading producer of these materials, also called nanocellulose.

Nanocellulose is simply wood fiber broken down to the nanoscale. For perspective, a nanometer is roughly one-millionth the thickness of an American dime. Materials at this minute scale have unique properties; nanocellulose-based materials can be stronger than Kevlar fiber and provide high strength properties with low weight. These attributes have attracted the interest of the Department of Defense for use in lightweight armor and ballistic glass. Companies in the automotive, aerospace, electronics, consumer products, and medical device industries also see massive potential for these innovative materials. Read more »

Nanotechnology Project Opens at Disney World

This post is part of the Science Tuesday feature series on the USDA blog. Check back each week as we showcase stories and news from the USDA’s rich science and research portfolio.

A visit to the happiest place on earth now opens a window to some of the smallest things on earth.

A new long-term exhibit at Walt Disney World’s INNOVNTIONS at Epcot® opened last month to educate the public about nanotechnology and the science of the very small. Take a Nanooze Break features a number of interactive activities that allow visitors to explore common objects at the nanometer scale, manipulate models of molecules and interact with scientists and engineers who conduct the latest nanotechnology research.

The exhibit gives new meaning to the phrase “it’s a small world after all” using six dynamic videos produced by Cornell University researcher Carl Batt and funded by USDA’s National Institute of Food and Agriculture.  The episodes, which were produced in collaboration with the international radio program EarthSky, cover both the potential benefits and risks of nanotechnology.  As part of the grant to Batt, the public will be surveyed to gain an understanding of their opinions about nanotechnology and the information conveyed by the videos.

Nanotechnology is the science of studying and producing materials and devices of nanometer size–billionths of a meter, or about 10,000 times smaller than the width of a human hair.  The emerging field of nanotechnology will no doubt lead to unprecedented understanding and control of the fundamental building blocks of all physical things. Potential applications are possible in plant and animal agricultural production, diagnostic devices to ensure food safety, food processing and manufacturing, human health and nutrition, biotechnology, medicine and drug delivery, information technology, homeland defense, energy production and efficiency, and environmental improvement.

Additional USDA funding into nanotechnology research has led to the development of a fabric that can detect biohazards such as E. coli, biosensors that can help detect diseases on farms and in hospitals, and to tracers that can uncover the sources of pollution in farm fields and waters.

The Epcot exhibit was based on the National Science Foundation-supported Nanooze children’s magazine and Web site designed to get kids excited about science and nanotechnology. With millions of people who visit Epcot each year, this work presents a great opportunity to share the latest advances in nanotechnology and how it can benefit our daily lives.
