Graphene improves circuits in flexible and wearable electronics

At 200 times stronger than steel, graphene has been hailed as a super material of the future since its discovery in 2004. The ultrathin carbon material is an incredibly strong electrical and thermal conductor, making it a ...

A sensor detects salt on the road to avoid excess

Engineers at Carlos III University in Madrid, Spain, have designed an optical sensor that detects how much salt is on road surfaces in real time. This avoids the need to spread the substance excessively, because although ...

The flip side of salting winter roads

Swedish scientists have studied models to help road and bridge maintenance engineers work out how much damage salting the roads in winter might cause to steel-reinforced concrete structures.
