The next application could make for a noisier world: Chinese researchers have found a way to make flexible, paper-thin loudspeakers out of nanotube sheets. The scientists say the technology could be used to add an auditory dimension to anything from clothing to magazines—and to prove their point, they put one on a waving flag. The nanospeakers don't generate sound like conventional speakers, which make noise by vibrating the surrounding air molecules. Instead, they harness a phenomenon called the thermoacoustic effect, which is how lightning produces thunder.
When an electric current runs through the nanotube sheets, they heat and expand the air near them, creating sound waves. 4. The nanotech version of this system is a glue that is ten times stickier than the gecko's feet. 3. The organic compounds in an OLED system emit light when an electric current is passed through them, and they need no backlight, making them thinner than traditional displays. 2. 1. Carbon nanotube. Using Carbon Nanotubes to Produce Electricity. The researchers of Massachusetts Institute of Technology (MIT) have uncovered a new phenomenon of carbon nanotubes.
They found that carbon nanotubes discharge powerful waves of electricity under certain circumstances. MIT team named it as thermopower waves. They are pinning their hope on thermopower waves to produce electricity to be utilized in small electrical appliances or maybe in large-scale applications too. This project was funded by the Air Force Office of Scientific Research, and the US National Science Foundation (NSF). This discharge of electricity from carbon nanotubes is a very rare occurrence. Traditionally we derive electricity from water, sun, wind, coal or heat produced by burning of fossil fuels.
Carbon nanotubes are submicroscopic structures. Researchers associated with this project find the whole phenomenon quite unusual. Researchers coated carbon nanotubes with a layer of reactive fuel that can generate heat by decomposing. What do you think? Carbon nanotube. Rotating Carbon Nanotube Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with length-to-diameter ratio of up to 132,000,000:1,[1] significantly larger than for any other material. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology.
In particular, owing to their extraordinary thermal conductivity and mechanical and electrical properties, carbon nanotubes find applications as additives to various structural materials. For instance, nanotubes form a tiny portion of the material(s) in some (primarily carbon fiber) baseball bats, golf clubs, or car parts.[2] Nanotubes are members of the fullerene structural family. Applied quantum chemistry, specifically, orbital hybridization best describes chemical bonding in nanotubes. Types of carbon nanotubes and related structures[edit] Terminology[edit] Torus[edit] Nanotech: Nanotubes Power Paper-Thin Battery. Collaboration among three separate groups of students at Rensselaer Polytechnic Institute has come up with the idea of a paper-thin battery.
Made mostly of cellulose -- the main fiber in paper -- embedded with carbon nanotubes and an electrolyte, the devices actually can be used as a battery, a supercapacitor or a combination of the two, depending on how it's assembled.

Clunky old batteries may soon be a thing of the past thanks to a new energy-storage device that looks and feels like a scrap of paper. Developed by a team of researchers at Rensselaer Polytechnic Institute (RPI), the nanoengineered battery is 90 percent cellulose, made up of the same plant cells used in nearly every type of paper. Worthy of Applause. Amazon Mechanical Turk. Circuit Simulator Applet. This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit.
