Systematically studying slippery surfaces

Betaines are materials with both a positively charged functional group and a negatively charged functional group linked by an alkyl chain spacer. This combination of functional groups causes betaines to strongly attract water, ...

High-precision control of printed electronics

Printed electronic transistor circuits and displays in which the colour of individual pixels can be changed, are two of many applications of ground-breaking research at the Laboratory of Organic Electronics, Linköping University. ...

New colored coating surface for superior rust resistance

Polymer chemists at Nagoya Institute of Technology in Japan invented a simple coating process to color metals, leading to higher performance and energy savings. The method involves a chemical modification to non-ionic polymers ...

Simple technique produces stronger polymers

Plastic, rubber, and many other useful materials are made of polymers—long chains arranged in a cross-linked network. At the molecular level, these polymer networks contain structural flaws that weaken them.
