 Smaller, better semiconductors have consistently allowed computers to become faster and more energy-efficient than ever before.

But the 18-month cycle of exponential increases in computing power that has held since the mid 1960s now has leveled off. That’s because there are fundamental limits to integrated circuits made strictly from silicon—the material that forms the backbone of our modern computer infrastructure.

As they look to the future, however, engineers at the University of Wisconsin-Madison are turning to new materials to lay down the foundations for more powerful computers.

They have devised a method to grow tiny ribbons of graphene—the single-atom-thick carbon material—directly on top of silicon wafers.

Scientist Discovers Cure For Smelly Feet

Scientist Discovers Cure For Smelly Feet 

 

Nano-technology or nano-tech, refers to a field of applied science whose theme is the control of matter on an atomic and molecular scale. It concerns structures that are 100 nanometers or smaller and involves developing materials or devices within that size range. Inventor, Vladimir Rudenov, claims that he has developed a cure for smelly feet involving the weaving of silver nano-fibers into socks. His attempts to channel his small business into the wave of Russia’s burgeoning nano-technology industry has transformed his invention and his company into a national success story.
