Electric cable bacteria breathe oxygen with unheard efficiency

Ten years ago, researchers at Aarhus University, Denmark, reported the discovery of centimeter-long cable bacteria, that live by conducting an electric current from one end to the other. Now the researchers document that ...

Electrons hop to it on twisted molecular wires

Researchers at Osaka University synthesized twisted molecular wires just one molecule thick that can conduct electricity with less resistance compared with previous devices. This work may lead to carbon-based electronic devices ...

"Better" copper means higher-efficiency electric motors

Researchers at Pacific Northwest National Laboratory (PNNL) have increased the conductivity of copper wire by about five percent. That may seem like a small amount but it can make a big difference in motor efficiency. Higher ...

Scientists develop inexpensive method to produce E-sail tethers

Thin metallic tethers for Coulomb drag devices that tow satellites and spacecraft can now be produced more easily than before. Scientists of the Finnish Meteorological Institute have developed a method to produce multi-wire ...

Solitonics in molecular wires could benefit electronics

Soliton descriptions for the conducting polymers polyacetylene—descriptions based around a type of solitary wave—caused great excitement when they first broke in the seminal reports by Su, Schrieffer, Heeger (SSH) and ...

The nano-guitar string that plays itself

Scientists at Lancaster University and the University of Oxford have created a nano-electronic circuit which vibrates without any external force.

Mechanical vibration generated by electron spins

Micro mechanical elements are indispensable components of modern electrical devices, but the actuation of them requires electrical current. It becomes harder to wire the element as further downscaling of device is pursued. ...
