By suspending tiny metal nanoparticles in liquids, Duke University scientists are brewing up conductive ink-jet printer "inks" to print inexpensive, customizable circuit patterns on just about any surface.

Ray of light could lead to next generation of superconductors

A superconductor, which can move electrical energy with no wasteful resistance, is the holy grail of cost-effective, efficient, and "green" power production. Unlike traditional conductors such as copper or silver, which waste ...

First flexible memory device using oxide ferroelectric material

For the first time, researchers have been able to deposit an ultra-thin oxide ferroelectric film onto a flexible polymer substrate. The research team used the flexible ferroelectric thin films to make non-volatile memory ...
