A recent report in the American journal Science says that advances in nanotechnology could lead to its introduction in Formula One in the near future.

Nanotechnology is the science of engineering materials with the properties of strength, lightness and electrical conductivity at the molecular, or nanometer, scale. According to Science the technology could be used to create artificial muscles, superstrong electric cars and wallpaper-thin electronics..

Scientists from the University of Texas and Australia's Commonwealth Scientific and Industrial Research Organization have reported the creation of industry-ready sheets of materials made from nanotubes -tiny carbon tubes with remarkable strength that are only a few times wider than atoms – that can also act as the semiconductors found in modern electronics.

The new material is self-supporting, transparent and stronger than steel or high-strength plastics, the sheets are flexible and can be heated to emit light. In laboratory tests, the sheets demonstrated solar cell capabilities, using sunlight to produce electricity.

One future application that scientists have discussed is the creation of racecars with stronger, lighter bodies that could also serve as batteries. Andrew Barron, a chemist at of Rice University in Houston. TX said, "We could see this on Formula 1 (racing) cars by next season. This is a jumping-off point for a technology a lot of people will pursue."

Nanotechnology and Manufacturing

Four years ago, words like "impossible," "futuristic," and "science fiction" filled discussions about nanotechnology. Since the announcement of the US National Nanotechnology Initiative in 2000, though, worldwide investment in nano research and development has raced forward, with $8 billion invested in 2004 alone. That kind of growth has leaders at major companies sitting up and taking notice of a technology that can help them develop enviable market positions.

The US National Science Foundation forecasts that nanotechnology could become a trillion dollar per year business by 2015, with advanced materials alone making up $340 billion of that figure. And there is no doubt that nanotechnology will soon change the way we manufacture. We hope you'll want to reap the benefits. Numerous industries-including automotive, aerospace/defense, cosmetics, clothing, computers, sporting goods, and pharmaceutical-are already using the technology to improve their products.

Nanotechnology is defined as the ability to control matter at the atomic or molecular scale of one to 100 nanometers. A nanometer is one billionth of a meter, about the size of a large molecule. To provide you with some perspective, a virus is about 100 nanometers long and a bacterium is ten times bigger; a human cell about ten times larger than that. Advanced nanomanufacturing requires precise control of materials and structures from the nanoscale all the way up to the macroscopic scale.

Nanoscale materials can exhibit superior and even unexpected properties. Partially a result of the atomic perfection possible at small scales, and partially due to nanoscale quantum effects, nanomaterials can be far stronger than their bulk constituents. Natural nanostructured materials like wood and seashells are thousands of times tougher than their raw materials. They go far beyond the chemistry of simple self-assembly, and are actively constructed out of molecular building blocks by the biological machines in the cells. For that reason, synthetic nanostructured materials should perform even better. Steel is one example of an early manmade nanocomposite material with better performance than its primary components of iron, carbon, and manganese.

Soon we'll be engineering far better materials.

Nanotechnology's champion material so far is the carbon nanotube. Discovered in 1991, these little tubes of carbon measure about one nanometer in diameter. They can be 100 times stronger than steel, can conduct heat better than any other material, and can be excellent electrical conductors, or semiconductors even better than silicon. Sensors made with nanotubes can be thousands of times more sensitive than bulk-scale sensors, and researchers are designing multifunctional materials that combine the properties of strength, sensing, and actuation.

Some companies are already moving nanomaterials into real products. Samsung is producing prototype computer displays using nanotubes as electron emitters. Eikos uses thin films of nanotubes to create an electrically conducting, but transparent, coating on glass to replace the industry-standard ITO film. You may have already hit a Wilson tennis ball containing nanocomposite clay for more bounce and a longer life, ridden an Easton bicycle made tougher and lighter by nanotubes, used a Kodak digital camera featuring a brighter, more powerefficient display built from carbon-based molecules, or worn stain and wrinkle-resistant Eddie Bauer khaki "nanopants" to work.

Even simple nanomaterials such as bulk nanopowders are finding markets. Nanoscale titanium dioxide decomposes most organic material when ultraviolet light falls on it. Several firms use this to create selfcleaning paint and glass products. Nanoscale aluminum oxide coatings on eyeglasses make their surfaces as hard as sapphire without affecting transparency.

These examples of "bottom-up" nanotechnology rely on molecular interactions to self-assemble structures at larger scales. As simple applications of advanced materials, they are just the beginning.

Developing "top-down" systems that build smaller and smaller systems, down to the molecular scale, will eventually enable us to use software to precisely control the positioning of chemical building blocks. Massively parallel nanomanufacturing systems will allow us to engineer and build extremely complex and highly functional materials, and devices, with atomic precision.

New materials and new ways of putting them together will be nanotechnology's next big success stories.

While today, we cast, grind, mill, etch, and cut to move large chunks of atoms at once, nanomanufacturing will ultimately enable us to:

* Build products with essentially every atom in its designed location,

* Make almost any stable structure consistent with the laws of physics,

* Do this at a manufacturing cost near that of the required raw materials and energy.

There is no doubt that whatever you are manufacturing now will be touched by nanotechnology in the next five years. Making things better, faster, and cheaper is industry's constant goal, and nanotechnology can help manufacturers surpass competitors who aren't paying attention.

Nanotechnology Unfolds Futuristic Green Cars

In the process of constant advancement in auto technology, car makers are pondering on manufacturing environment-friendly vehicles utilizing nanotechnology. Two of the much-anticipated future vehicles of this concept are Acura FCX 2020 Le Mans and Volkswagen Nanospyder.

Automakers are constantly incorporating the most advanced technology in their lineup. This time around they are planning to use nanotechnology to come up with spectacular vehicles. Two of the most sought-after vehicles are Acura FCX 2020 Le Mans and Volkswagen Nanospyder.

Recently, automakers have unleashed their environment-friendly concept cars that are expected to be manufactured using nanotechnology. The latter is a technology of building tiny machines using functional systems at a molecular scale. According to experts, nanotechnology, in its original sense, means projected ability to assemble items from the bottom up, utilizing techniques and tools being developed these days to make complete, high performance products.

Nanotechnology works from the bottom to the inside of the machine called personal nanofactories (PNs). Using mechanochemistry, nanotechnology will facilitate control at the nanometer scale. A nanometer is one billionth of a meter. Basically, it is about the width of 3 to 4 atoms.

One of the striking future cars presented is FCX 2020 Le Mans from Acura. Said car is envisioned to be powered by advanced auto parts from the automaker. It will also be using Honda car accessories to boost its ergonomics and comfort.

Acura FCX 2020 Le Mans appears like a Batmobile. The difference is that it uses lightweight and recyclable materials. Moreover, it is equipped with a hydrogen fuel cell drivetrain that makes it an environment-friendly car. Its molecular nanotechnology made it lighter and more manageable than present day cars.

Another viable future car is Volkswagen Nanospyder. The captivating car is made up billions of spore-like nanobots. The car is inclusive of mouth, eyeballs and other Volkswagen car accessories including tiny logos.

One of the exciting features of this VW Nanospyder is the ability of its lead bots to pick up impending collisions. Aside from that, the information can be sent away to support particular sections of the car.

Analysts in the auto industry are expecting a greener car future because of nanotechnology. In fact, there have been interesting concept cars submitted in the upcoming Los Angeles Auto Show’s Design Challenge. The latter is a competition designed to cover future cars that are environment-friendly. Mechanics of the competition include originality, safety, environmentalism and relevancy to Southern California’s 'green' lifestyle.

Unique research efforts relating to the development of Nanoscale devices to replace standard integrated circuits, and eventually entire electronic systems. Standard integrated circuits (IC) have limitations or restrictions in size, speed, reliability, complexity and finding suitable replacements for discontinued items. Nanoscale device development and understanding has dramatically grown. One of the key properties of quantum physics that quantum computers rely on is the ability of certain atoms or nuclei to work together as quantum bits. These computing devices are a fraction of the size of typical ICs (nanoscale). Nanoscale devices developed using quantum physics principles have unlimited potential to revolutionize the methods and design of fabricated printed circuit cards and complete systems. They can replace an entire PC hoard

or the set of PC boards that comprise a Line Replaceable Unit (LRU). This would be a good and practical

jumping-off point to going directly to the complete device, system, or function level. This might include a nanoscale computer (general purpose or flight control), transmitter, GPS receiver, position andor attitude sensors in either a stand-alone configuration, or combined within conventional devices (e.g., a nanoscale communications suite (xmtdrcvr, etc.) encapsulated within the Plexiglas canopy or the control yoke of an F16 rather than behind the instrument panel or maybe the whole comm suite into the pilot’s helmet.
