Electronic signal expands material by a factor of 100

Researchers at the Laboratory of Organic Electronics, Linkoping University, have discovered a material that can both increase and reduce its volume when exposed to a weak electrical pulse. In a sponge, or filter, the researchers ...

Jumping the gap may make electronics faster

A quasi-particle that travels along the interface of a metal and dielectric material may be the solution to problems caused by shrinking electronic components, according to an international team of engineers.

How viruses outsmart their host cells

Viruses depend on host cells for replication, but how does a virus induce its host to transcribe its own genetic information alongside that of the virus, thus producing daughter viruses? For decades, researchers have been ...

Learning transistor mimics the brain

A new transistor based on organic materials has been developed by scientists at Linköping University. It has the ability to learn, and is equipped with both short-term and long-term memory. The work is a major step on the ...

Sending spin waves into an insulating 2-D magnet

Quantum Hall ferromagnets are among the purest magnets in the world—and one of the most difficult to study. These 2-D magnets can only be made in temperatures less than a degree above absolute zero and in high magnetic ...

Electronic skin stretched to new limits

An electrically conductive hydrogel that takes stretchability, self-healing and strain sensitivity to new limits has been developed at KAUST. "Our material outperforms all previously reported hydrogels and introduces new ...
