Organic LEDs for electronic light source

Electronic products pollute our environment with heavy before, during and after many metals are used. Only in United States estimated that 70% of heavy metals in landfills come from electronic discarded. With floor get large screen televisions and cheaper every year, environmental costs continue to grow.

To counteract this, a new solution from Tel Aviv University applies a discovery in nano-technology, based on carbon nanotubes peptide Dimer, "green" to the optics industry and electronics. the Nadav Amdursky and Prof. Gil Rosenman Department of electrical engineering at Tel Aviv University scientists say their technology could make green flat screen TV production and can even make medical - equipment as more sensitive subcutaneous ultrasound - devices.

Inspired by a biomaterial involved in Alzheimer's disease research, discovered by Professor Ehud Gazit, Department of Microbiology of the University and biotechnology, researchers developed a new nano material, application of scientific disciplines of biology and biological material física.Este is the basis for its new variety, environmentally friendly (LED) light-emitting diodes used in both consumer and medical electronics.

TV in a test tube?
Scientists say that his new invention is more than a clean and green way to create light.It also generates a strong signal that can be used in other applications of nano-world motors, actuators and ultrasound.

"We're growing our own sources of light," says Amdursky, working under the supervision of Professor Rosenman.Los nano-lightsticks organic, which he and their supervisors have developed using PhD student organic chemistry are facts of carbon, making them cheap, as well as environmentally friendly.

Unlike conventional light sources, light source biologically derived has a scale architecture nanometric, facilitating the integration of light as LED TVs and improvement of the así.El image resolution output devices from Tel Aviv University team has recently written a patent to cover its "organic LEDs".

According to Amdursky, the light emitted by the new light sticks is not appreciably different from which emanates from the LED lights inorganically engineering today.

"We do not need a special plant, bacterium or a large machine to grow these structures," says Amdursky, who said that technology applications are wider than the wide screen TV. structures described in advanced materials, Nano letters-core technology and ACS Nano, present "piezoelectric characteristics," necessary for the development of nano-ultrasound tiny that failed to parse the cuerpo.Motores piezoelectric or actuators inside cells machines are only tens of nanometers wide, which can lead to your application in the energy harvested as super-capacitors-devices required for the solar wind energy power company great energy storage systems.
