Quote:
Researchers from the US Department of Energy's Argonne National Laboratory have created a new combination material from graphene and diamonds that's able to almost entirely overcome friction. The property, known as superlubricity, is highly sought after for its potential use in a wide range of mechanical systems.


Very cool! Use that in any machine with moving parts and you'll get a much more efficient machine. Internal combustion engines come immediately to mind. You'll get better gas mileage, more power to the wheels, and lower operating temperatures.

Though these results were extremely promising, the team did encounter one confusing issue. While the diamond/graphene combination material performed its job admirably under dry conditions, superlubricity was not maintained when it was introduced to a humid environment.

To solve the mystery, the researchers turned once again to atomistic calculations that revealed that the presence of a water layer inhibited nanoscroll formation, causing higher levels of friction as a result.

The team believes that the findings could have a significant impact on the field.


Well, crud. So it will work for snowmobiles and such.

Or in hermetically sealed dry environments.

But not for genitals, where it's needed the most.

Totally frictionless sounds boring. And painfully out of control. Moderation in all things, my friend.

Besides, sticking diamond powder in delicate places sounds like it's asking for trouble.

Don't judge me!
