This is frustrating as supposed scientists plainly ignore a dimension for headline grabbing press. Graphene and nano tubes both have three dimensions. It doesn't matter that one dimension is small.

Yes, they are all three dimensional. But their construction/use is not. Nanotubes are essentially a rolled cylinder of graphene, but their electrical properties turn graphene’s 2-dimensional electrical properties into a single dimension (down the axis). The new materials this article describes maintain the same electromagnetic properties as a single sheet of graphene, but in a third dimension, allowing for much thicker materials, giving you much more volume. The issue with graphene is that when stacked, the special properties diminish and are no longer as useful.
