New low friction coating allows grease-free lubrication and corrosion protection

New low friction coating allows grease-free lubrication and corrosion protection | Science et Technique | Scoop.it
Machine parts wear, if there is friction between their metal surfaces. Lubricants and functional oils help prevent this. They attract dirt, debris and dust, and over time form lumps  or become resinous.

Marc Kneepkens's curator insight, June 8, 2014 6:11 PM

Renewable energy is catching up quickly.

Eric Chan Wei Chiang's curator insight, June 9, 2014 1:50 AM

Supercritical water have properties between those of a gas and a liquid. Generating supercritical water is not an easy task as very high temperatures and pressures are required i.e. more than 374 °C and 218 atm.

 

Power plants can extract ten times more energy from supercritical water as compared to typical steam or hot water.

 

Icelandic scientists previously tried to generate supercritical water from geothermal means http://sco.lt/7mbwvZ
