“#Direct observation of desorption of a melt of long polymer chains” Credit: CC0 Public Domain In our everyday life it’s not uncommon to see the same material in different states. Take for example water: it’s a liquid at ambient temperature, we can convert into ice when cooled below 0°C and it becomes a gas when…
“#From old jeans to new T-shirt” Wound onto a spool, the viscose filament yarn was spun from recycled cotton provided in form of cellulose sheets. Researchers at the Fraunhofer IAP have found a way to turn cotton clothes such as jeans into new high-quality garments rather than lowly cleaning rags. Credit: Fraunhofer IAP The technical…
