M-Spin produce metallic mats with >1000x the surface area of competing products. But, OK, so what? Why is surface area so important? Why do we make such a big deal about it? This article explores why surface area matters, how M-Spin creates materials with such a high surface area, and how this drives high performance. “God made the bulk; surfaces were invented by the devil” – Wolfgang Pauli Surfaces behave very differently to the inside (or “bulk”) of materials. In the bulk every atom of the material is surrounded (and bonded to) other atoms. However, at the surface the atoms are missing neighbours. Other atoms and molecules can take the place of the missing neighbours, binding to the surface, and undergoing reactions. Chemical reactions with solids always take place at surfaces.
