Moire patterns in graphene
Researchers at the National Institute of Standards and Technology and the Georgia Institute of Technology have demonstrated that atomic scale moire patterns, an interference pattern that appears when two or more grids are overlaid slightly askew, can be used to measure how sheets of graphene are stacked and reveal areas of strain.

Read moreNew electrolytic cells to play a role in tomorrow's local energy supply
Lower CO2 emissions demand more renewable energy in the energy system. This calls for new solutions that take account of the considerable variations in the amount of wind energy, hydropower, solar energy etc. One of the solutions is a distributed energy system. Here it must be possible to store surplus energy locally using, for example, local SPEC electrolytic cells. The foundation for this technology is being developed by the CASE research project.
