Study: Thin layers of water behave like ice at room temperature

AKRON, Ohio, Aug. 29 (UPI) -- When scientists at the University of Akron sandwiched a thin layer of water between two charged surfaces, they observed ice-like tendencies.

These unique behaviors allow the nanometer-thin layer of water to withstand intense pressure. Until now, scientists couldn't quite figure out why water squeezed between two surfaces didn't get pushed out entirely.

The new research, detailed in the journal Science Advances, shows the naturally occurring charges of the two sandwiching surfaces "freeze" the water -- trap it by inducing ice-like properties. The slippery water-ice layer reduces the friction between the two surfaces and keeps them separated.

"For the first time we have a basic understanding of what happens to water under these conditions and why it keeps two surfaces apart," researcher Ali Dhinojwala, a professor at Akron, said in a news release. "We had suspected something was happening at the molecular level, and now we have proof."

Scientists say the realization could inspire improved frictionless or low-friction technologies. Joint replacements like knee implants could be made more effective by reduced friction.

The thin layer of water could also be used to protect surfaces from microbial growth. Conversely, the research might help scientists find ways to repel water and enhance adhesiveness in wet conditions.
