Working toward a ‘triple threat’ graphene transistor
Anyone paying attention to science or technology this year must have noticed that graphene is a big deal. As in two guys, Andre Geim and Konstantin Novoselov, both at the University of Manchester (UK), winning a Nobel Prize in physics for (more or less) launching graphene on its way to fame and fortune. Hardly a [...]

Graphene oxide memristors combine cheap and flexible
In electronics graphene is quickly becoming the great hope for replacing and improving upon silicon semiconductors. Since silicon semiconductors are the basis of much commercial electronics (especially computing), we’re talking the Big Time here. This attracts a lot of research money, which in turn attracts researchers to probe opportunities in a number of directions. One [...]

A new use for nanowires: E-skin (electronic skin)
What’s in a word? Call it a membrane and most people associate it with something scientific. Call it skin and there are definite human associations. So when the engineers at the University of California Berkeley (USA) developed a pressure sensitive electronic material made of nanowires, is it a membrane or skin? They’d like to call [...]

Graphene: Diverse advances
Scientists thought they understood carbon, until nanotechnology came along. Working with carbon at the atomic level (the nanoscale) has revealed many surprising properties. In particular, graphene, a sheet of carbon one atom thick with the atoms arranged in a lattice of hexagons like a honeycomb, has proven to be astonishingly versatile. For example, two recent [...]

Biosensors: A sensor/probe inside a single cell
Can scientists put sensors inside single cells? The answer used to be, yes, but not without damaging the cell (a little or a lot). Cells, human or otherwise, are very small. Human cells vary from nerve cells at about 10 microns (that’s millionths of a meter) to 50 microns for heart cells (still very small). [...]

Nanotube transistors powered by the body’s own energy source
Adenosine Triphosphate (ATP) is the ultimate energy of life. It’s the energy source that powers almost all living cells. Now, in research conducted by Alexandr Noy and colleagues at the Lawrence Livermore National Laboratory (California, USA), ATP is also an energy source for carbon nanotubes transistors that can eventually be used to link living tissue [...]

Graphene transistors
Start with the fact that digital computers run on transistors; transistors are key. Next, consider graphene, the nanotechnology cousin of graphite, a versatile material that has hit the news many times in the past several years. Finally, with regard to transistors and computers, graphene has already been dubbed the ‘successor to silicon’; now it looks [...]

Concept news: A one-molecule transistor
Two scientists, Mark Reed, the Harold Hodgkinson Professor of Engineering & Applied Science at Yale (USA), and Takhee Lee, a former Yale postdoctoral associate and now a professor at the Gwangju Institute of Science and Technology (South Korea), have been working for more than a decade to show that a transistor (the fundamental electronic element [...]
