Due to their unique electronic structure and remarkable physicochemical properties, carbon nanotubes have captured the interest of scientists worldwide. Cientifica Ltd recently predicted that the market for nanotubes and nanofibers would surge from around $173.7 million in 2005 to $3.62 billion by 2010, reflecting an annual growth rate of over 60%. Frost & Sullivan also forecasts that the demand for carbon nanotubes alone could reach $540 million by 2007. As production techniques improve, the cost of carbon nanotubes is expected to drop significantly over the next decade, paving the way for broader commercial applications.
A recent article in "Chemical Market Report" highlighted that carbon nanotubes are set to become a key material across multiple industries. Researchers are actively exploring various uses, such as in electric connectors, solar cells, and even breast cancer treatment. Additionally, these materials can be used to create high-strength carbon fiber composites, which are expected to play a major role in civil engineering and construction projects.
Carbon nanotubes are one-dimensional quantum materials with extraordinary structural properties. Their potential benefits make them highly promising in fields like physics, chemistry, and materials science. For instance, due to their length being thousands of times their diameter, they are often referred to as "super fibers."
In November of last year, Bayer MaterialScience AG, a German technical service agency, announced the launch of its carbon nanotube product under the brand name Baytubes at a price of €100 ($120) per kilogram. The company claims a purity level exceeding 99% and a significant reduction in production costs. According to the project manager, adding a small amount of Baytubes to plastic components can eliminate the need for environmentally friendly water-soluble coatings or powder coatings. The product can also be used in anti-static packaging films, electronic components, and electromagnetic interference shielding for computers and mobile phones.
In 2004, GE Corporation developed a nano-diode by connecting two carbon nanotubes with different electrical characteristics. In August of last year, GE reported improvements to the device, allowing it to operate beyond previous theoretical limits. The company compares this breakthrough to the shift from vacuum tubes to transistors. Meanwhile, Applied Nanotech and Shimane Masuda Electronics are planning trial production of 25-inch LCD TVs using carbon nanotubes. These displays are expected to offer superior image quality and lower power consumption compared to traditional LCDs.
Experts from the Lawrence Berkeley National Laboratory suggest that carbon nanotubes could serve as a silicon alternative in semiconductor wafers. If production costs continue to decline, they may also be used on a large scale for affordable solar energy generation. Researchers at Rensselaer Polytechnic Institute and the U.S. Air Force Research Laboratory are testing carbon nanotube-based ignition systems that could replace conventional spark plugs. At Rice University, scientists are also working on diagnostic tools and treatments for breast lumps using carbon nanotubes.
Boiler tubes are used in fire-tube boiler, a type of boiler in which hot gases from a fire pass through one or more tubes running through a sealed container of water.
