MIT'S TECHNOLOGY REVIEW has an important report by Katherine Bourzac, "Spinning Nano Yarns", which highlights several important advances in nano-material fabrication. Up til now, nano-fibers have been laboratory exotics, "unobtainium" expensive. It seems there are going to be changes:
Many important technologies—from battery electrodes and superconducting wires to the catalysts in fuel cells—rely on materials containing powdered particles, which can be tricky to manage. Now, in a feat that could simplify the production of many such technologies and might point the way toward some radical new ones, researchers at the University of Texas have demonstrated a way to spin yarn out of nanotubes infused with useful powdered materials.
The researchers have used the method to make strips of yarn that function as a battery electrode, others with superconducting properties, and self-cleaning yarns.
Now, why should you care? The advent of nano-materials is going to be as revolutionary as the transistor and will affect every aspect of life in 2020 and beyond. How so? For starters, cars will weigh 50%, maybe even less than what they weigh now. Then there's medicine, electronics — you ain't seen nuthin' yet.
