Ultra-sensitive polymer detects explosive devices

(Phys.org) —A chemical that's often the key ingredient in improvised explosive devices (IEDs) can be quickly and safely detected in trace amounts by a new polymer created by a team of Cornell chemists.

Hybrid carbon nanotube yarn muscle

Professor Seon Jeong Kim of Hanyang University has created a high capacity yarn muscle that does not require electrolytes or special packaging. It will have a big impact in the motor, biological and robot industry.

Flexible polymer opals

A synthetic material which mimics the brightest and most vivid colours in nature, and changes colour when twisted or stretched, has been developed by researchers at the University of Cambridge, and could have important ...

Top-class biofuel from the depths of the forest
