World’s Smallest Electronic Circuit

Just like electronic Gadgets, electronic circuits are also getting smaller. The study by McGill University and Sandia National Laboratories has resulted in the development of world’s tiniest electronic circuit. This is actually a phenomenon on slightly higher stage than atomic level. The circuit which just consists of only two wires is seen as a future of smaller electronic industry.



The ‘get small’ attitude of the industry is reflected in this research. The specialty of the circuit is two bare wires separated by 15nm distance or roughly around 150 atoms thick. The distance is the main parameter which brings a phenomenon called Coulomb Drag into play. When the two wires are kept undisturbed in each other’s vicinity, the wires behave in a different way than normal. Current starts flowing in them but in opposite directions. In other words if the current flowing through one of the component wire if considered positive, the current in other wire flows negatively as if to cancel the effect. However as we are seeing electronic action in the setup, it is termed as an electric circuit; perhaps the smallest in the world until now!

Surprisingly we are overcoming a difficulty in this circuit, it is the heat generated in it. In normal circuits, heat has to be dissipated through the use of extended surfaces or ‘fins’. However, as the distance is smaller, the heat generated will be smaller as adjacent wires can easily absorb those minute quantities. Moreover, speed will also be a parameter and a point of advantage of these electronic circuits over the conventional ones. The setup being smaller than ordinary, electrical signals will take lesser time to travel from one point to another.
The discovery was a part of research by Guillaume Gervais from McGill’s Physics Department and Mike Lilly from Sandia National Laboratories. The experimental facts and the consequent results were published in online edition of Nature Nanotechnology titled Positive and Negative Coulomb Drag in Vertically Integrated One-Dimensional Quantum Wires.

'Solar Paint' That Generates Electricity !

Green homeowners can now bid goodbye to unwieldy solar panels! An inexpensive "solar paint" has been developed by the researchers at the University of Notre Dame in the US, which can be applied on the outside walls of a house to generate electricity from sunlight. The electricity thus produced by "Sun-Believable Solar Paint" can be used to power the home appliances and equipment on the inside, claim researchers.

"By making use of recent advances in semiconductor nanocrystal research, we have now developed a one-coat solar paint for designing quantum dot solar cells," said Prashant V. Kamat of the Radiation Laboratory and Department of Chemistry and Biochemistry at the University of Notre Dame in Indiana, one of the lead authors of the study. 


"By incorporating power-producing nanoparticles, called quantum dots, into a spreadable compound, we've made a one-coat solar paint that can be applied to any conductive surface without special equipment," Kamat added. 


Talking about the quantum dots in detail, he said these are "semiconductor nanocrystals which exhibit size-dependent optical and electronic properties. In a quantum dot sensitised solar cell, the excitation of semiconductor quantum dot or semiconductor nanocrystal is followed by electron injection into TiO2 nanoparticles. These electrons are then transferred to the collecting electrode surface to generate photocurrent. The holes that remain in the semiconductor quantum dot are removed by a hole conductor or redox couple and are transported to a counter electrode."

Due to its amazing properties, Kamat and his co-workers christened the new paint as "Sun-Believable Solar Paint". If perfected, the new product is sure to herald a new era in solar power. 

Unfortunately, the paint isn't ready for commercial use yet. At around 1 per cent, its efficiency is much less than traditional solar cells. "The best light-to-energy conversion efficiency we've reached so far is 1 per cent, which is well behind the usual 10 to 15 per cent efficiency of commercial silicon solar cells. But this paint can be made cheaply and in large quantities. If we can improve the efficiency somewhat, we may be able to make a real difference in meeting energy needs in the future," Kamat said.  

Robots To Increase Your Efficiency

Technology has always proved to be a boon for the physically-challenged people. This time we have exoskeletans, also known as light robots, which are technology pieces that increase the efficiency of the person who wears them. 

The robots are particularly helpful in case of chronic diseases. For instance, in case of soldiers, who have chronic back injury because of carrying heavy loads on their back across rough terrains. These robots help the soldiers carry a lot more. Ekso Bionics - formerly Berkeley Bionics, has made exoskeletons, which can help a person carry as much as 200 pounds of weight for 20 kilometers and walk up to six hours. 






This robot also helps patients suffering from stroke, paralysis and osteoporosis or anyone else with mobility issues or in a wheelchair to walk. Eythor Bender, chief executive officer of Ekso Bionics, said to ET, "When I'm 80 years old and want to go skiing or snowboarding, I can do so by just wearing a bionic device instead of undergoing surgeries.”

When it comes to bionic devices, most of them need to be surgically implanted, which can be complicated. The fact that this robot can be donned like a piece of clothing makes it distinctive. It is now market-ready and will be launched in January 2012. The ET report quoted Larry Fisher as saying, "While it is revolutionary, the cost factor means it will not be a market that grows quickly.”

Ekso's products costs approximately $130,000, plus an annual service charge of about $10,000. The company plans to sell it to 11 rehabilitation centres in the US, including the renowned Rehabiliation Institute of Chicago (RIC), where the world's first bionic man Jesse Sullivan got his legendary bionic arm.
