Way back in the early days of 2011, the world's smallest electric motor was so...big. At 200 nanometers wide, it was a whopping 1/300th the size of a human hair.
Now, chemists at Tufts University's School of Arts and Sciences have smashed that record, which was set in 2005, with this weekend's unveiling of their single-molecule electric motor, which at 1 nanometer wide could be the first in an entirely new class of devices with potential use in medicine and engineering.
That's right: 1 nanometer. That's been estimated to be about 1/60,… Read more
