Supercooled Water Transforms Into New Form of Liquid

[QUOTE][B]Researchers at the University of Arkansas have identified that water, when chilled to a very low temperature, transforms into a new form of liquid.[/B]

Through a simulation performed in “supercooled” water, a research team led by chemist Feng “Seymour” Wang, confirmed a “liquid-liquid” phase transition at 207 Kelvins, or 87 degrees below zero on the Fahrenheit scale.

The properties of supercooled water are important for understanding basic processes during cryoprotection, which is the preservation of tissue or cells by liquid nitrogen so they can be thawed without damaged, said Wang, an associate professor in the department of chemistry and biochemistry in the J. William Fulbright College of Arts and Sciences.

“On a microsecond time scale, the water did not actually form ice but it transformed into a new form of liquid,” Wang said. “The study provides strong supporting evidence of the liquid-liquid phase transition and predicted a temperature of minimum density if water can be cooled well below its normal freezing temperature. Our study shows water will expand at a very low temperature even without forming ice.”

The findings were published online July 8 in the journal Proceedings of the National Academy of Sciences. Wang wrote the article, “Liquid–liquid transition in supercooled water suggested by microsecond simulations.” Research associates Yaping Li and Jicun Li assisted with the study.

The liquid–liquid phase transition in supercooled water has been used to explain many anomalous behaviors of water. Direct experimental veri?cation of such a phase transition had not been accomplished, and theoretical studies from different simulations contradicted each other, Wang said.

The University of Arkansas research team investigated the liquid–liquid phase transition using a simulation model called Water potential from Adaptive Force Matching for Ice and Liquid (WAIL). While normal water is a high-density liquid, the low-density liquid emerged at lower temperatures, according to the simulation.[/QUOTE]

I'm sorry, but your nickname shouldn't be "Seymour" if your last name is Wang.

Nonetheless this is really cool.

[Zambies!]

Can't even focus on the implications I can only seymour Wang

[ithon]

is it me or does the article not include the pressure induced on the matter?

I'm pretty sure that that's [I]exactly[/I] why he chose it.
Although "Fang Wang" works too, I imagine it would scare off the ladies.

Oh yeah, on topic: water's cool.

I am finding it hard to imaging what "liquid–liquid" would look like.

Maybe it's something like frozen ice.

Slush.

look up a video about hydrogen or helium supercooled. if kept at the right temperature it can flow like a fountain indefinitely due to it's density or viscosity or some shit

Reshy the sciencedaily bot

[GreenLeaf]

this is something that i'd really like to see in action!

[QUOTE=Scot;41469672]I am finding it hard to imaging what "liquid–liquid" would look like.[/QUOTE]

pretty sure liquid-liquid in this case just means it's a liquid to liquid transition i.e. in contrast to say, a gas to liquid transition

[Water-Marine]

U of A, representing! The Fulbright Science department is pretty fucking impressive.

I'd like to Seymour Wang in action as well.

now make the 9th state of Ice.

this isn't what the article is even about

[wulfe8857]

Isn't this just a superfluid? I thought we already knew about those.

if the computer model predicts something that has not been found through precise experimentation, and has additional models producing contradictory results then maybe there is a problem with this model too. its not been confirmed through experimentation and the theoretical side isn't very solid either. computer models are just that though, models of what we can

models are only built off of what we can observe though

That's a super-liquid. It has zero viscosity and defies gravity.

That's bullshit. That isn't water, that's a sodium acetate solution. The same stuff they use in heat packs.

Passing it off as supercooled water that suddenly crystalizes is a common youtube trick.

Put your standard bottle of water (ex: Ozarka) in your freezer. Wait maybe an hour or two. Then, if it's still liquid, very carefully bring it to a table, then hit the table with the water. I've been doing this for years. But that won't stop you from not believing me now would it?

i've made nice slushies using that trick

but you're right my life experiences are nothing compared to your vast and unlimited knowledge master!!!
