A novel, new form of carbon, dubbed "Q-carbon", is harder than diamond. The new phase, discovered by Jagdish Narayan and Anagh Bhaumik of North Carolina State University in Raleigh, US, results from the rapid quenching of liquid carbon produced by high-power nanosecond laser pulses on amorphous carbon. The material can be a semiconductor or metallic, depending on temperature. It is ferromagnetic and, depending on the cooling rate, can be formed with tiny diamonds. The process takes place under normal temperatures and pressures and is inexpensive, making bulk, low-cost diamond production look very feasible, in addition to there now being a very interesting new form of carbon.
