Nanotubes Can Shape Water Molecules Into 'Two-Dimensional Ice' (phys.org)
Iwastheone quotes Phys.org:
First, according to Rice University engineers, get a nanotube hole. Then insert water. If the nanotube is just the right width, the water molecules will align into a square rod. Rice materials scientist Rouzbeh Shahsavari and his team used molecular models to demonstrate their theory that weak van der Waals forces between the inner surface of the nanotube and the water molecules are strong enough to snap the oxygen and hydrogen atoms into place. Shahsavari referred to the contents as two-dimensional "ice," because the molecules freeze regardless of the temperature.
He said the research provides valuable insight on ways to leverage atomic interactions between nanotubes and water molecules to fabricate nanochannels and energy-storing nanocapacitors... The researchers already knew that hydrogen atoms in tightly confined water take on interesting structural properties. Recent experiments by other labs showed strong evidence for the formation of nanotube ice and prompted the researchers to build density functional theory models to analyze the forces responsible... They discovered that nanotubes in the middle diameters had the most impact on the balance between molecular interactions and van der Waals pressure that prompted the transition from a square water tube to ice.
The paper describes "solid-like water nanotubes," and the head of the research team believes they could have practical applications, according to the article.
"Nanotube ice could find use in molecular machines or as nanoscale capillaries, or foster ways to deliver a few molecules of water or sequestered drugs to targeted cells, like a nanoscale syringe."

An ice IX nano-environment!
First I have this question: does this research mean homeopathy and "memory of water" is true after all?

what no ice-nine? https://en.wikipedia.org/wiki/...
It always gives the same insane advice: You need teeny little ice cubes for making teeny little drinks like you need teeny little hands for milking mice. Original: https://people.well.com/user/b...
Not sure what color it actually is, but black seems likely. Cool.
When all you have is a hammer, every problem starts to look like a thumb.
Call me topologically challenged, but to me that sounds like either one or three dimensions.
See subject: Your MASSIVE FAIL in this life is you're nothing more than a chattering little do-nothing "ne'er-do-well" online & you know it...
* Is that the best your "phantasyland FAKE NAME" (for your fake lie of a so-called 'life') can manage?
When a FAKE NAME do nothing like YOU does better than I have? Then talk (you're all talk & no action)...
You can't help you're an immature little BUTTHURT no-mind, lol! I blew you away in TONS OF PLACES and easily dust your no-mind bullshit blatherings.
APK
P.S.=> The TRUE PRICE of your UNIDENTIFIABLE FAKE NAME do-nothing selves like you that I can ALWAYS CASH IN ON (lol) is that I can use FACT/TRUTH on them to SHATTER their all TOO fragile delusional egos that they actually know A DAMN THING in computing, lol... apk
See subject & you do-nothing soyboy "ne'er-do-wells" are too COWARDLY and EFFEMINATE to ban bump stocks. This would be REAL SECURITY that would put an end to mass shootings. The estrogen in soy milk makes all of you too cowardly to BAN BUMP STOCKS.
* The NRA is supported by George Soros, the Russian government, Jews, and their allies in the Vatican. The Vatican has MEDDLED in our elections to support Hillary Clinton and OPPOSE any form of GUN CONTROL. They work with the Jewish elites in the United States to add SOY MILK to our foods, containing ESTROGEN and making our men EFFEMINATE.
A ban on bump stocks would have STOPPED many recent MASS SHOOTINGS including at the Waffle House, Las Vegas, Parkland, and so many other places. It is TRULY PATHETIC that you SOYBOY WEASELS insist on keeping bump stocks legal. A ban on bump stocks will STOP MASS SHOOTINGS just like my HOSTS FILE ENGINE is a cure-all for INTERNET SECURITY.
Losers like Coren22, arth1, Zontar The Mindless, AssFux (lol), and so many more of you UNIDENTIFIABLE FAKE NAME losers attack me relentlessly for telling the TRUTH. It takes a REAL MAN like me to continually dust all of you you weasels, while you LIE and ACCUSE me of evil criminal acts. You are INCAPABLE of accepting the TRUTH that BUMP STOCKS MUST BE BANNED.
APK
P.S.=> I will continue to DUST your feeble arguments and SWOOP IN wherever you UNIDENTIFIABLE WEASELS keep lying and trolling. You are truly a sad and pathetic sight to see... apk

Yields more security/speed/reliability/anonymity vs. any SINGLE solution (99% of threats = hostnames vs. IP address that most firewalls use) more efficiently/FASTER + NATIVELY 4 less!
(Vs. "Bolt on 'MoAr' illogic-logic" competitors slowing you, hosts speed you up 2 ways (adblocks + hardcodes u spend most time @) vs. competition loaded w/ bugs (DNS/AntiVir) + their overheads (messagepass ('souled-out' to advertiser addons) + filtering drivers) & their complexity leads to exploitation).
* ONLY 1 of its kind in GUI on Linux/BSD!
(Much better vs. Windows model in speed & efficiency + new "merge" feature)
APK
P.S.=> I use Firefox on Linux & it works like a DREAM w/ hosts. You stupid níggers can benefit from my greatness as God's gift to you... apk
Your software is just fine - well written, functional... I'm going to continue using the Host File Engine by mmell February 17, 2017
Your premise that hostfiles are a good way to deal with advertising and malvertising is quite valid - by JazzLad April 20, 2016
his hosts program is actually pretty good by xenotransplant August 10 2015
his hosts tool is actually useful for those cases in which one does indeed want to locally block stuff outright while consuming minimum system resources by alexgieg September 25 2015
I like your host file system by Karmashock September 09 2015
that APK guy, I use his host file by rogoshen1 Tuesday March 03, 2015
I personally use a HOSTS file blocker produced from a genius called APK by 110010001000 October 27 2017
* Best part = Linux 64-bit model's faster/more efficient (2x work in 1/2 the time)
APK
P.S.=> For a faster/safer/more reliable internet. Even you stupid níggers can benefit from my greatness. God's gift to Slashdot will NEVER be silenced... apk
Polywater without the impurities.
Would be nice to know which phase the ice was, TFA is light on details. I'm guessing the nanotube causes the molecules to act as if they are under high pressure. Have they mapped the P vs T? Wonder what would happen if the ice in the nanotubes was shifted through a phase change.
I am pretty sure this is one-dimentional, rather than "Two-Dimensional Ice". Or, at a finer scale, maybe 3-dimensional.... where do they get two?

I was sad to see no Abyss comments. I'm looking forward to seeing some watery Mary Elizabeth Mastrantonio water sculptures.
