Acid-free approach leads to strong conductive carbon nanotube threads

The very idea of fibers made of carbon nanotubes is neat, but Rice University scientists are making them neat - literally. The single-walled carbon nanotubes in new fibers line up like a fistful of uncooked spaghetti through a process designed by chemist Angel Martí and his colleagues.

Novel varistor embedded ceramic transistor hybrid devices

New work demonstrates that varistors and transistors are inherently coupled devices. These hybrid devices can simultaneously be used in the same electronic circuit as a varistor to protect the circuit elements against overshoot of prescribed voltage supply and as a transistor for signal amplification and electronic switch.

Nanoscale study sheds new light on why batteries go bad

A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought - and that the benefits of slow draining and charging may have been overestimated. The results challenge the prevailing view that 'supercharging' batteries is always harder on battery electrodes than charging at slower rates.

Understanding hydrogen uptake by a single palladium nanoparticle

Researchers have determined for the first time the mechanism by which nanometer-sized particles of palladium take up hydrogen. Because the properties of nanoparticles change greatly with their size, choosing the right types of nanoparticle allows you to fine-tune the properties of materials.
