WASHINGTON, June 26 /PRNewswire/ -- Many people see nanotechnology as a futurist dream. Tomorrow's nano world promises pollution-free energy, potent cancer and Alzheimer's treatments, and faster, smaller, cheaper computers.

Few appreciate that nanotechnology is quickly moving out of laboratories and into factories, stores, and homes. Lux Research reports that more than $32 billion in products incorporating nanotechnology sold last year. These include about 300 nanotechnology consumer products, and an estimated 600 nanotechnology raw materials, intermediate components, and industrial equipment items used by manufacturers.

What are the challenges of moving nanotechnology from laboratory to store shelves? How do you use nanotechnology to add value to products, and to shift competitive dynamics? Do you brand or not brand nanotechnology products, and how do you address consumer perceptions? What does responsible development of nanotechnology mean to a company?

A program to address these and other questions will be held on Thursday, June 29th at 12:30 p.m. in the 6th floor board room of the Woodrow Wilson International Center for Scholars.

The featured guest is Dr. Barry Park, chief operating officer of Oxonica. Oxonica is one of Europe's leading nanomaterials firms taking nano-enabled products from laboratory to market.

The company was spun out of Oxford University in Great Britain in 1999. Its commercialized products include Envirox Fuel Borne Catalyst (used in diesel engines to reduce fuel consumption and particulate emissions) and Optisol UV Absorber (a photostable UV absorber that provides enhanced and longer lasting protection against UVA in suncare and anti-aging products). In 2005, Boots Group plc -- Britain's foremost pharmacy chain -- incorporated Optisol in their new Soltan Facial Sun Defense Cream, now sold widely in stores throughout the United Kingdom.

Researchers at the Hong Kong University of Science and Technology (HKUST) have developed a new technology that can greatly enhance the ballistic-proof strength of ultra high molecular weight polyethylene (UHMWPE) fiber by adding carbon nanotubes to pristine high-strength fiber.

Jointly developed by the Departments of Chemical Engineering and Mechanical Engineering, the new technology is expected to pave the way for new UHMWPE applications, such as more comfortable and effective bullet-proof vests and extra-durable nautical rope.

Carbon nanotubes can improve the engineering properties of plastic fibers in ballistic-resistant garments enabling the garments to withstand forces with very high impact yet remain light. In addition, the high ventilating capability of carbon nanotubes means end products can be made more comfortable for users.

The HKUST technology represents a significant breakthrough for researchers. Dr Ping Gao, Associate Professor of Chemical Engineering, said: "The technology we have developed can effectively align nanotubes along the length of polymer fibers so the tensile strength of nanocomposite fiber becomes up to eight times stronger than steel."
Prof Tong-Xi Yu, Chair Professor and Head of Mechanical Engineering, added: "Materials with higher ductility are usually softer. The stiffer the materials, the less ductile they are. Our technology creates fibers that are both stiff and ductile-the ideal material for energy absorption."

Postdoctoral researcher Dr Shilun Ruan, who fabricated and characterized the new materials during his PhD study at HKUST, said the materials could be utilized in both engineering and our daily lives. They can replace anti-ballistic and durable steel or other alloys as well as being used in many everyday products to enhance performance.

"As the materials can withstand very high tensile force, they can be used, for example, to produce tennis racket threads with stronger elasticity. When used as strings for musical instruments, the nanocomposite fibers can also generate beautiful, high-quality music," Dr Ruan said.

Dr Gao noted that the Hong Kong plastic industry has become more aware of the market potential of engineering plastics. This latest technology developed at HKUST will help the industry to enhance its competitiveness further.
