The so-called "nanonet" technology - circuits made of numerous carbon nanotubes randomly overlapping in a fishnet-like structure - has been plagued by a critical flaw: The network is contaminated with metallic nanotubes that cause short circuits. The discovery solves this problem by cutting the nanonet into strips, preventing short circuits by breaking the path of metallic nanotubes. Researchers at the University of Illinois at Urbana-Champaign led experimental laboratory research to build the circuits, and Purdue led research to develop and use simulations and mathematical models needed to design the circuits and to interpret and analyze data. The nanonets are made of tiny semiconducting cylinders called single walled carbon nanotubes.
The researchers created a flexible circuit containing more than 100 transistors, the largest nanonet ever produced and the first demonstration of a working nanonet circuit, Alam said. The advance may allow researchers to use carbon nanotube transistors to create high-performance, shock-resistant, lightweight and flexible integrated circuits at low cost, Alam said.


A key advantage of the nanonet technology is that it can be produced at low temperatures, enabling the transistors to be placed on flexible plastic sheets that would melt under the high temperatures required to manufacture silicon-based transistors, he said. Possible applications include an electronic skin that covers an aircraft and automatically monitors the formation of cracks to alert technicians and prevent catastrophic failures. Such shape-conforming electronics are not possible using conventional silicon-based circuits, which are manufactured on rigid wafers or glass plates. Flexible displays could be integrated into automotive windshields to provide information for drivers.
Conventional circuits for flat-panel televisions contain transistors made of materials called polysilicon or amorphous silicon, which cannot be used in flexible applications. Nanonet transistors are promising for so-called macroelectronics because they are best suited for large-scale applications, but these transistors may not be as well suited for the requirements of microelectronic circuits, such as those in computer chips, Alam said. Each nanonet transistor consists of numerous strips of nanotubes, separated bylines that are etched in place. Future research may include work focusing on learning the reliability of the carbon nanotube circuits.
The research has been funded by the National Science Foundation through the Network for Computational Nanotechnology at the Birck Nanotechnology Center in Purdue's Discovery Park. The researchers used computers made available by a global network called the nanoHUB, an Internet-based science gateway that provides computer-based resources for research and education in the areas of nanoelectronics and nanoelectromechanical systems and their application to nano-biosystems. Nanoelectronics focuses on creating a class of electronic devices containing features measured in nanometers, equivalent to one-billionth of a meter.
The Network for Computational Nanotechnology uses advanced theory and simulations to explore new ideas for digital switching devices such as innovative types of transistors that promise to help researchers create future electronics. The research is complementary to work by Purdue researcher David Janes, a professor of electrical and computer engineering. These are two photos of flexible circuits created using carbon nanotubes in research at Purdue University and the University of Illinois at Urbana-Champaign.
It’s like hearing a sunny weather forecast and getting the biggest snowstorm in years instead. I’ve been expecting the storm about two days ago but when the time passed without any disturbance I thought it missed us. The initial CME impact arrived just on schedule (as predicted by NASA), shortly before 2am UTC.
When there is an earthquake nearby, the mirror starts swinging – this messes up the magnetometer record, but can be used to detect earthquakes quite far from here.


In addition to being identified as some of the best published work, these papers as a set have long-term reference to the engineering community and to society at-large. It is a specialized test equipment just like electronics engineers use to "see electrical signals". The manual is in full color and shows you every single experiment and with wireless breadboard. The paper was written by the Purdue engineers and University of Illinois researchers : John A. Other potential applications include "electronic paper" that displays text and images, solar cells that could be printed on plastic sheets and television screens capable of being rolled up for transport and storage.
If the nanonet area is large enough, the overlapping metallic nanotubes will eventually form a meandering string across the entire transistor, causing a short circuit.
Because the carbon nanotubes are twice as numerous as the metallic tubes, enough of them exist to form a complete circuit. The lines are easy to create with a standard etching process used in the semiconductor industry. His work involves transparent circuits using a different type device called nanowires, made of indium oxide instead of carbon nanotubes.
The researchers have overcome a major obstacle in producing transistors from networks of carbon nanotubes, a technology that could make it possible to print circuits on plastic sheets for applications including flexible displays and an electronic skin to cover an entire aircraft to monitor crack formation. George Professor of Electrical and Computer Engineering, and doctoral students Ninad Pimparkar and Jaydeep P. But if the device is segmented into strips, this meandering path of metallic rods is cut at the point where the lines separate one strip from another, preventing short circuits.
The models and simulations are needed to tell researchers precisely how wide to make the strips so that the pathway of metallic tubes is cut but the carbon nanotubes complete their circuit. Department of Energy, Motorola Corp., and by the university's Frederick Seitz Materials Research Lab, the Center for Microanalysis of Materials and the Department of Chemistry. The interplanetary magnetic field (IMF) near our planet tipped south, opening a crack in Earth’s magnetosphere.
NOAA analysts believe the fluctuation in IMF is related to the arrival of a CME originally expected to miss Earth.
