In the future, your cell phone calls and television pictures could become a lot clearer thanks to tiny antennas thousands of times smaller than the width of a human hair. At least thats the speculation of a University of Southern California researcher who has been investigating nanotube transistors.
The USC scientist, Bart Kosko, Ph.D., a professor in the schools Electrical Engineering Department, led a study that has demonstrated for the first time that minuscule antennas, in the form of carbon nanotube transistors, can dramatically enhance the processing of electrical signals, a development that could pave the way for improved performance of consumer electronic devices.
The finding adds to a growing number of promising electronic components that are nanotube-based, including logic gates for computers and diodes for light displays. The study appears in the December issue of Nano Letters, a monthly peer-reviewed publication of the American Chemical Society, the worlds largest scientific society.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
