Coating cuts amount of microplastic fibres entering waterways

The material contains a layer that can take on two conformations: solid copper that retains most infrared heat, which helps keep the building warm; or a watery solution that emits infrared, which can help cool the building

Building material offers low-energy solution to maintaining temperature

Twistrons, made from spun CNTs, convert mechanical movement into electricity. Scanning electron microscope images show how UT Dallas researchers made a new kind of twistron by intertwining three individual strands of spun carbon nanotube fibres to make a single yarn, similar to the way conventional yarns used in textiles are constructed. A previous version of a harvester (right) was made by coiling the CNT fibres. The scale bars indicate 100 micrometres
