Those grain boundaries occur because graphene grown in labs usually using CVD are not perfect and this creates several islands of graphene that merge together . The researchers say that at these points , graphene is about half as strong as perfect . graphene The atoms on the lines

  • Graphene used to create highly corrosive water

    Updated: 2013-03-13 14:19:25
    Researchers from the National University of Singapore (NUS) have managed to create water that is corrosive enough to etch diamonds. This was discovered by mistake - the researchers attached a layer of graphene on diamond, and then heated it to a high temperature (to encourage bonding). Water molecules that were trapped between the diamond and graphene could not escape (because graphene is impermeable ).The "trapped", heated water transformed into a supercritical phase that behaves differently compared to "normal" water. It even corroded the diamond. read more

  • Graphene used to find the origin of 1/f noise after almost a century of research

    Updated: 2013-03-08 08:52:45
    Researcherrs from the University of California (UC Riverside) have finally (after almost a century of research) managed to find out what causes the low-frequency electronic 1/f noise (also known as pink noise or flicker noise). Using graphene sheets, it was found that 1/f noise is a surface phenomenon that shows up in situations that are thinner than 2.5 nm (at least for graphene). Graphene was essential for this work because you can test for 1/f noise using a single sheet, and then add sheet after sheet (basically adding just one-atom to the thickness of the conductive material). This cannot be done with metal films. read more
