The hidden nanoworld of ice crystals: Revealing the dynamic behavior of quasi-liquid layers
(PhysOrg.com) -- A wide range of phenomena depend on ice specifically, phase transitions during ice crystal surface melting. In this transition, which occurs near the melting point, the ice surface ...
Scientists create one-dimensional ferroelectric ice
(PhysOrg.com) -- Everyone knows that when water freezes, it forms ice. But a lesser known fact is that there is not one, but many different kinds of ice, depending on the way the ice crystals are arranged. ...
China looks to 'combustible ice' as a fuel source
(PhysOrg.com) -- Buried below the tundra of China’s Qinghai-Tibet Plateau is a type of frozen natural gas containing methane and ice crystals that could supply energy to China for 90 years. China discovered ...
Antifreeze proteins can stop ice melt, new study finds
The same antifreeze proteins that keep organisms from freezing in cold environments also can prevent ice from melting at warmer temperatures, according to a new Ohio University and Queen's University study ...

Scientists isolate new antifreeze molecule in Alaska beetle
Scientists have identified a novel antifreeze molecule in a freeze-tolerant Alaska beetle able to survive temperatures below minus 100 degrees Fahrenheit. Unlike all previously described biological antifreezes that contain ...

Physicists find evidence of new state of matter in a simple oxide
Symmetry is a fundamental concept in physics. Our ‘standard model’ of particle physics, for example, predicts that matter and anti-matter should have been created in equal amounts at the big bang, yet our ...

The secret life of water at very low temperatures
The secret life of water just got weirder. For years water has been known to exist in 15 phases -- not just the merry threesome of solid, liquid and gas from grade school science. Now, University of Utah chemists ...

Freezing: a phenomenon that 'jumps'
(PhysOrg.com) -- The freezing of suspensions of particles is not always a uniform phenomenon; in certain conditions it leads to a modification of the redistribution of particles and the growth of crystals.

Scientists use rare mineral to correlate past climate events in Europe, Antarctica
The first day of spring brought record high temperatures across the northern part of the United States, while much of the Southwest was digging out from a record-breaking spring snowstorm. The weather, it seems, has gone ...

The enduring mystery of snowflakes
Who hasn't caught a snowflake in a mitten and marveled at its starlike detail, and then recalled that no two snowflakes are alike? But these crystals of ice are even more different than one might imagine - ...
