Graphene is the miracle material that has proven difficult to commercialize for practical purposes. There are a number of approaches under way that hope to accomplish that.

But now, Nature Materials (via Kurzweil.net) reports about a new form of cadmium arsenide that has electrical properties similar to graphene but which might be easier to put to practical use because of its 3-dimensional structure (graphene is essentially a 2-dimensional material, consisting of carbon molecules a single atom thick). The cadmium arsenide material is in a form referred to as a three-dimensional Dirac semimetal.

If either graphene or cadmium arsenide semimetal can be produced at industrial scales, it will revolutionize medical device design.
