A paper in the journal Nano Letters reports the invention of flexible, conductive textiles dipped in a carbon nanotube "ink" that could be used to store energy, perhaps paving the way for wearable batteries, solar cells and other electronics.
Perhaps one of the hottest areas in carbon research today, however, involves the "miracle material" graphene. Graphene is a sheet of carbon only one atom thick. It's the strongest material known while still being ultralight and flexible. And it conducts electricity better than copper. Mass-producing graphene is a challenge, though researchers in April reported that they could make large amounts using nothing but a kitchen blender. If scientists can figure out how to make lots of graphene easily, the material could become huge in tech. Imagine flexible, unbreakable gadgets that also happen to be paper-thin.
Carbon has come a long way from charcoal and diamonds, indeed. A carbon nanotube CNT is a minuscule, straw-like structure made of carbon atoms. These tubes are extremely useful in a wide variety of electronic, magnetic and mechanical technologies. The diameters of these tubes are so tiny that they are measured in nanometers. A nanometer is one-billionth of a meter — about 10, times smaller than a human hair. Carbon nanotubes are at least times stronger than steel, but only one-sixth as heavy, so they can add strength to almost any material, according to nanoScience Instruments. They are also better than copper at conducting electricity and heat. Nanotechnology is being applied to the quest to turn seawater into drinking water.
In a new study, scientists at Lawrence Livermore National Laboratory LLNL have developed a carbon nanotube process that can take the salt out of seawater far more efficiently than traditional technologies. For example, traditional desalination processes pump in seawater under high pressure, sending it through reverse osmosis membranes. These membranes then reject all large particles, including salts, allowing only clean water to pass through. However, these desalination plants are very expensive and can only process about 10 percent of a county's water needs, according to LLNL. In the nanotube study, the scientists mimicked the way biological membranes are structured: essentially a matrix with pores inside the membrane.
They used nanotubes that were particularly small — more than 50, times thinner than a human hair. These tiny nanotubes allow for a very high flux of water but are so narrow that only one water molecule can pass through the tube at a time. Finally, the process requires a heated gas, blown over the substrate and catalyst. The gas contains the carbon that grows into nanotubes. Quantum dots are synthesize d using different methods. In one method, small crystals of two different elements are formed under high temperatures. By controlling the temperature and other conditions, the size of the nanometer-scale crystals can be carefully controlled.
The size is what determines the fluorescent color. These nanocrystals are quantum dots—tiny semiconductors—suspended in a solution. Dendrimer s are complex nanoparticles built from linked, branched units. Each dendrimer has three sections: a core, an inner shell, and an outer shell. In addition, each dendrimer has branched ends. Each part of a dendrimer—its core, inner shell, outer shell, and branched ends—can be designed to perform a specific chemical function. Dendrimers can be fabricate d either from the core outward divergent method or from the outer shell inward convergent method. Like buckyballs and some other nanomaterials, dendrimers have strong, cage-like cavities in their structure. Scientists and researchers are experimenting with dendrimers as multi-functional drug-delivery methods.
A single dendrimer, for example, may deliver a drug to a specific cell, and also trace that drug's impact on the surrounding tissue. Nanocomposites combine nanomaterials with other nanomaterials, or with larger, bulk materials. NCMCs, sometimes called nanoclay s, are often used to coat packing materials. MMC s are stronger and lighter than bulk metals. MMCs may be used to reduce heat in computer "server farms" or build vehicles light enough to airlift.
Industrial plastics are often composed of PMCs. One promising area of nanomedical research is creating PMC "tissue scaffolding. This could revolutionize the treatment of burn injuries and organ loss. Scientists and engineers working at the nanometer-scale need special microscope s. The atomic force microscope AFM and the scanning tunneling microscope STM are essential in the study of nanotechnology. These powerful tools allow scientists and engineers to see and manipulate individual atoms. AFMs use a very small probe —a cantilever with a tiny tip—to scan a nanostructure.
The tip is only nanometers in diameter. As the tip is brought close to the sample being examined, the cantilever moves because of the atomic forces between the tip and the surface of the sample. The tip moves up and down to keep both the signal and the distance from the sample constant. AFMs and STMs allow researchers to create an image of an individual atom or molecule that looks just like a topographic map. Top-down nanomanufacturing involves carving bulk materials to create features with nanometer-scale dimensions.
For decades, the process used to produce computer chips has been top-down. Producers work to increase the speed and efficiency of each "generation" of microchip. The manufacture of graphene-based as opposed to silicon-based microchips may revolutionize the industry. Bottom-up nanomanufacturing builds products atom-by-atom or molecule-by-molecule. Experimenting with quantum dots and other nanomaterials, tech companies are starting to develop transistor s and other electronic devices using individual molecules.
These atom-thick transistors may mark the future development of the microchip industry. American physicist Richard Feynman is considered the father of nanotechnology. Modern nanotechnology truly began in , when the scanning tunneling microscope allowed scientists and engineers to see and manipulate individual atoms. The Binnig and Rohrer Nanotechnology Center in Zurich, Switzerland, continues to build on the work of these pioneering scientists by conducting research and developing new applications for nanotechnology.
By the end of the 20th century, many companies and governments were investing in nanotechnology. Major nanotech discoveries, such as carbon nanotubes, were made throughout the s. By the early s, nanomaterials were being used in consumer products from sports equipment to digital cameras. Modern nanotechnology may be quite new, but nanometer-scale materials have been used for centuries. As early as the 4th century, Roman artists had discovered that adding gold and silver to glass created a startling effect: The glass appeared slate green when lit from the outside, but glowed red when lit from within.
Nanoparticles of gold and silver were suspended in the glass solution, coloring it. The most famous surviving example of this technique is a ceremonial vessel , the Lycurgus Cup. Artists from China, western Asia, and Europe were also using nanoparticles of silver and copper, this time in pottery glazes. This gave a distinctive " luster " to ceramic s such as tiles and bowls. In , modern microscopy revealed the technology of " Damascus steel ," a metal used in South Asia and the Middle East until the technique was lost in the 18th century—carbon nanotubes.
Swords made with Damascus steel are legendary for their strength, durability, and ability to maintain a very sharp edge. One of the most well-known examples of pre-modern use of nanomaterials is in European medieval stained-glass windows. Like the Romans before them, medieval artisans knew that by putting varying, small amounts of gold and silver in glass, they could produce bright reds and yellows. Many government s, scientists, and engineers are researching the potential of nanotechnology to bring affordable, high-tech, and energy-efficient products to millions of people around the world.
Nanotechnology has improved the design of products such as light bulbs, paints, computer screens, and fuels. Nanotechnology is helping inform the development of alternative energy sources, such as solar and wind power. Solar cells, for instance, turn sunlight into electric current s. Nanotechnology could change the way solar cells are used, making them more efficient and affordable. Solar cells, also called photovoltaic cells, are usually assembled as a series of large, flat panels. These solar panels are big and bulky. They are also expensive and often difficult to install. Using nanotechnology, scientists and engineers have been able to experiment with print-like development processes, which reduces manufacturing costs.
Some experimental solar panels have been made in flexible rolls rather than rigid panels. In the future, panels might even be "painted" with photovoltaic technology. The bulky, heavy blades on wind turbine s may also benefit from nanotech. An epoxy containing carbon nanotubes is being used to make turbine blades that are longer, stronger, and lighter. Other nanotech innovations may include a coating to reduce ice build-up. Nanotech is already helping increase the energy-efficiency of products.
One of the United Kingdom's biggest bus operators, for instance, has been using a nano-fuel additive for close to a decade. Engineers mix a tiny amount of the additive with diesel fuel, and the cerium-oxide nanoparticles help the fuel burn more cleanly and efficiently. Access to clean water has become a problem in many parts of the world. Nanomaterials may be a tiny solution to this large problem. Nanomaterials can strip water of toxic metals and organic molecules. For example, researchers have discovered that nanometer-scale specks of rust are magnetic, which can help remove dangerous chemicals from water.
Other engineers are developing nanostructured filter s that can remove virus cells from water. Researchers are also experimenting with using nanotechnology to safely, affordably, and efficiently turn saltwater into freshwater, a process called desalination. In one experiment, nano-sized electrode s are being used to reduce the cost and energy requirements of removing salts from water. Scientists and engineers are experimenting with nanotechnology to help isolate and remove oil spilled from offshore oil platform s and container ships. One method uses nanoparticles' unique magnetic properties to help isolate oil.
Oil itself is not magnetic, but when mixed with water-resistant iron nanoparticles, it can be magnetically separated from seawater. The nanoparticles can later be removed so the oil can be used. Another method involves the use of a nanofabric "towel" woven from nanowires. These towels can absorb 20 times their weight in oil. Hundreds of consumer products are already benefiting from nanotechnology.
You may be wearing, eating, or breathing nanoparticles right now! Scientists and engineers are using nanotechnology to enhance clothing.Concurrent but unconnected to Similarities Between Beowulf And King Arthur Kroto-Smalley work, astrophysicists were working with spectroscopists to study infrared emissions from giant red carbon stars.
