Application of electro-active biofilms [PDF]
, 2010 The concept of an electro-active biofilm (EAB) has recently emerged from a few studies that discovered that certain bacteria which form biofilms on conductive materials can achieve a direct electrochemical connection with the electrode surface using it ...

Nucleation mechanism for the direct graphite-to-diamond phase transition [PDF]
, 2011 Graphite and diamond have comparable free energies, yet forming diamond from graphite is far from easy. In the absence of a catalyst, pressures that are significantly higher than the equilibrium coexistence pressures are required to induce the graphite ...
