In our humble opinion: One layer is true graphene (the real deal); 2 to 10 Layers is multilayer graphene; More than 10 layers is actually graphite. But, why is multilayer graphene not as good as people think? If you can imagine a “small” deck of cards, say up to ten cards, you bond the […]
Carbon has some properties that makes it special: it tends to form covalent bonds, and it prefers to have four of them. Note that the carbon-carbon bonds are record strong (not to be confused with hardness), which certainly paves the way to a lot of weary interesting combinations, as illustrated by many allotropes of carbon […]
Graphene is a 2-dimensional, crystalline allotrope of carbon, and can be described as a one-atom thick layer of graphite. In graphene, carbon atoms are densely packed in a regular sp2-bonded atomic-scale chicken wire (hexagonal) pattern. Never mind what sp2-bond means, it is the structure of graphene which gives it much of its unique properties, and makes […]

The story of graphene goes back to some 158 years ago, where in 1859, Sir Benjamin Collins Brodie described the highly lamellar structure of thermally reduced graphite oxide. But it wasn’t until 1916 that the structure of graphite was first discovered, and not until 1947 for P. R. Wallace to consider […]
CealTech AS – Endless Possibilities – posted by Dexter Johnson Read the article here: CealTech-AS–Endless-Possibilities Established in 2012, Norway-based CealTech AS is already staking claim to being the largest volume producer of graphene in the world. This past year, 2016, was a big year in the company’s development with a number of landmark events […]
