(PhysOrg.com) -- Engineers from Harvard University have designed and demonstrated ice-free nanostructured materials that literally repel water droplets before they even have the chance to freeze.

Supercooling, a state where liquids do not solidify even below their normal freezing point, still puzzles scientists today. A good example of this phenomenon is found everyday in meteorology: clouds in high altitude are an ...

(PhysOrg.com) -- Scientists have known for generations that hot water can sometimes freeze faster than cold, an effect known as the Mpemba effect, but until now have not understood why. Several theories have been proposed, ...
(PhysOrg.com) -- Just as water can be superheated and remain liquid above the boiling point if there is no nucleating surface (such as a surface defect or a speck of dust), it can also become supercooled and remain liquid ...
(PhysOrg.com) -- Compared to any other liquid on Earth, water behaves in strange and unexpected ways, yet its unusual properties enable and protect life as we know it. By tracking individual water molecules in a "supercooled" ...

Clouds are a lot cooler than you might think. In fact, scientists might say they're super cool because they're made up of millions of supercooled water droplets, droplets that have been cooled below the freezing point but ...

Researchers at EPFL have found a way to study water in "no man's land," a subzero temperature range where water crystallizes rapidly. Historically, the inability to access "no man's land" has prevented scientists from unriddling ...

When Einstein was working toward his PhD, he was among the first to explain how particles exhibit random motions in fluids. Diffusion is an important physical process and the Stokes–Einstein relationship describes how particles ...

Water has many unusual properties, such as its solid form, ice, being able to float in liquid water, and they get weirder below its freezing point. Supercooled water—below freezing but still a liquid—is notoriously difficult ...
