Nanofluids: No “Magic” Cooling Capabilities

August 31, 2007 | Leave a Comment

Not so super-cool after all: MIT researchers knock down theory about nanofluids. ‘MIT engineers have shown that nanofluids, which once held promise as a super-coolant, do not have the theoretical cooling capabilities many scientists believed they had.
Nanofluids are suspensions of tiny particles on the nanometer, or billionth of a meter, scale. When nanofluids were first [...]
