Unlocking the mysteries of freezing in supercooled water droplets
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 haven't yet turned into ice......»»
Why tiny metal droplets take longer to solidify into glass: Fundamental observation in materials science
Most people who hear the word 'glasses' will probably think of drinking glasses or corrective eyewear. Hardly anyone will think of metals. But metallic glasses, or 'amorphous metals' as they are also known, are playing an increasingly important role.....»»
