Is glass a solid or a liquid? This question, which has been vigorously debated by specialists in the field for some decades, has just been answered anew: "Glass is a non-equilibrium, non-crystalline state of matter that appears ...

Famously described as 'the deepest problem in solid state physics' by Nobel Laureate, Philip Andersen, the glass transition, by which a liquid transforms into a solid without freezing, is shedding its mystique.

We learn in school that matter comes in three states: solid, liquid and gas. A bored and clever student (we've all met one) then sometimes asks whether glass is a solid or a liquid.

Zoom in on a crystal and you will find an ordered array of atoms, evenly spaced like the windows on the Empire State Building. But zoom in on a piece of glass, and the picture looks a bit messier—more like a random pile ...

Polymers are used for myriad applications today, and perhaps the most important property that dictates which polymer is chosen for a given application is its "glass transition temperature." Many industrial polymers possess ...

Glasses are not, perhaps surprisingly, technically solid in a crystalized form, but are substances frozen in a liquidlike structure. Many fundamental questions remain as to exactly how glasses form, transitioning from flowing ...

Over time, when a metallic glass is put under stress, its atoms will shift, slide and ultimately form bands that leave the material more prone to breaking. Rice University scientists have developed new computational methods ...

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 ...
