Stanford university rightoriginal Studyposted by Tom Abate-Stanford on September 27 2013engineers have built a basic computer using carbon nanotubes a success that points to a potentially faster more efficient alternative to silicon chips.
Mihail Roco a senior advisor for nanotechnology at the National Science Foundation called the work n important scientific breakthrough. t was roughly 15 years ago that carbon nanotubes were fashioned first into transistors the on-off switches
But a bedeviling array of imperfections in these carbon nanotubes has frustrated long efforts to build complex circuits using CNTS.
and low-power switching make carbon nanotubes excellent candidates to serve as electronic transistors. NTS could take us at least an order of magnitude in performance beyond where you can project silicon could take uswong said.
Depending on how the CNTS grow a fraction of these carbon nanotubes can end up behaving like metallic wires that always conduct electricity instead of acting like semiconductors that can be switched off.

#Explosives and Pesticides Can Be detected by Using Bee venom Scientists from MIT have discovered that by coating carbon nanotubes in bee venom,
In a new Nature Materials paper, the researchers report boosting plantsability to capture light energy by 30 percent by embedding carbon nanotubes in the chloroplast,
the researchers also embedded semiconducting carbon nanotubes, coated in negatively charged DNA, into the chloroplasts. Plants typically make use of only about 10 percent of the sunlight available to them,
but carbon nanotubes could act as artificial antennae that allow chloroplasts to capture wavelengths of light not in their normal range, such as ultraviolet, green,
With carbon nanotubes appearing to act as a rosthetic photoabsorber photosynthetic activity measured by the rate of electron flow through the thylakoid membranes was 49 percent greater than that in isolated chloroplasts without embedded nanotubes.
When nanoceria and carbon nanotubes were delivered together, the chloroplasts remained active for a few extra hours. The researchers then turned to living plants
Lean green machines The researchers also showed that they could turn Arabidopsis thaliana plants into chemical sensors by delivering carbon nanotubes that detect the gas nitric oxide,
it alters the tube fluorescence. e could someday use these carbon nanotubes to make sensors that detect in real time, at the single-particle level,
While one-dimensional materials such as carbon nanotubes and nanowires also allow excellent electrostatics and at the same time possess band gap they are not suitable for low-cost mass production due to their process complexities she said.
#Single Atom Building blocks For Future Electronics The material is called a silicene, a layer of silicon single atoms arranged in a honeycomb pattern that was fabricated first by researchers at UOW Institute for Superconducting and Electronic Materials (ISEM) and their partners in Europe and China.
and Dr Yi Du have published breakthrough research into a new material call silicene. An ISEM team led by Professor Shi Xue Dou
and Dr Yi Du have published breakthrough research into a new material call silicene. Silicene great promise is related to how electrons can streak across it at incredible speed
close to the speed of light. Propelling the electrons in silicene requires minimal energy input, which means reducing power and cooling requirements for electronic devices. f silicene could be used to build electronic devices,
it could enable the semiconductor industry to achieve the ultimate in miniaturization, Dr Yi Du,
a research fellow at the ISEM, said. The difficulty for researchers, according to Dr Du, is that up until a couple of years ago,
was the first research group in Australia to make silicene and recently, using state-of-the-art equipment,
and modifying silicene so it can be integrated it into ultra-small renewable energy devices, such as solar cells,
data storage hardware and advancing quantum computing. uow195685 o one in the scientific community believed silicene paper could be made
and place them one at a time on a plate to form the silicene paper. he process is like laying bricks,
and high-quality silicene layers that are large enough for integrated circuits, Dr Du said. here is also work to be done in developing ways to peel
and transfer the silicene layers from the base it has been assembled on, as well as embed electrodes in it. s
