Example Sentences

To create nontoxic, biodegradable and high-performing lubricant additives for water power turbines, researchers turned to ionic liquids, or ILs: organic liquid salts that mix well with oil, reduce friction between bearings and gears, and are stable in a range of temperatures.

From Science Daily

"Our previous work showed us that you could dramatically increase the performance of lubricants with the addition of just 1% or even a half-percent of ILs," said ORNL's Jun Qu, who leads the project and the Surface Engineering and Tribology group at ORNL.

From Science Daily

Although ILs are generally considered less toxic than conventional lubricant ingredients, their impact on the environment has not been closely studied.

From Science Daily

The team first sought to eliminate potential toxic elements such as fluorine and chlorine and metals such as zinc and iron from the candidate ILs.

From Science Daily

They also focused on creating ILs made up of shorter hydrocarbon chains -- chains containing fewer than six carbon atoms -- which are generally considered to be less toxic.
