The supernova that caused the nebula was recorded by Japanese and Chinese astronomers in the 12th century. Now, we know exactly what the aftermath looks like.
However, the researchers didn’t set out to 3D-print semiconductor-free devices that could behave like silicon-based transistors. This project grew out of another in which they were fabricating ...
Massachusetts Institute of Technology (MIT) researchers developed a semiconductor-free logic gate that can be used for simple workloads. The fully 3D-printable logic gate features a biodegradable ...
