(Phys.org)—While it may look like researchers from Tsinghua University in Beijing are sketching out an idea for a circuit on a piece of paper, they're actually using a special pen that draws real circuits using carbon-nanotube-based ...
Scientists have known how to draw thin fibers from bulk materials for decades. But a new approach to that old method, developed by researchers at MIT, could lead to a whole new way of making high-quality fiber-based electronic ...
