I’m following nanotechnologies world from some years. This science amaze me every time with unexpected discovery.
Last news I fond on the web, is very closed to Tempco field of work, the heat exchange.
Following this link, you can read an interesting technical story:
MIT make a
MIT experiment with magnetite nanoparticles dissolved in water for cooling systems, where the use of magnets increases by 300% the heat exchange coefficient of the nanofluid, which otherwise behaves like normal water.
The system would be more economical for the construction of particular geometries in exchange surfaces (fins and grooves), and could be applied to localized cooling, for example in electronic components …
