Radical electric motor runs without metal coils
Scientists at the Korea Institute of Science and Technology (KIST) have developed a new class of lightweight, highly conductive carbon nanotube (CNT) wiring that does away with copper and aluminum entirely. Using a process called Lyotropic Liquid Crystal-Assisted Surface Texturing (LAST), they've…
Scientists at the Korea Institute of Science and Technology (KIST) have developed a new class of lightweight, highly conductive carbon nanotube (CNT) wiring that does away with copper and aluminum entirely. Combined with a chemical rinse, the process also removes metal catalyst impurities created during manufacturing while maintaining the critical one-dimensional nanostructure that makes CNTs so special. While CNTs can reduce material mass significantly, the manufacturing of them doesn't come without a hefty environmental price tag – most are still made from fossil fuels in energy-hungry processes that generate toxic byproducts we still have to contend with.
