A way of making ammonia using a liquid-metal catalyst requires one-fifth less heat and 98% less pressure than conventional processes, say the inventors at RMIT University, Australia.
Researchers at North Carolina State University, USA, have tried making man-made cellulosic fibres from non-wood sources such as agricultural residues and dedicated fibre crops.
Radical polymerisation is boosted by using remote spark discharge from a Tesla coil, without needing conventional catalysts or polymerisation initiators.
