Nanofluids: nanoparticles suspended in fluid: 400% better as coolant

By suspending nanoparticles in water or other liquids, Professor Richard Williams and Dr Yulong Ding have created 'nanofluids' which can transfer heat up to 400% faster than other liquids. In a central heating system, nanofluids could increase efficiency without the need to use a more powerful pump, so saving energy and providing major environmental benefits.
