There’s very little that’s practical about these paper circuits. Oh, except that they can be printed out as a template and glued directly to a cardboard base. From there, builders can trace markings ...

Watch this video to learn more about what an electrical circuit is and how it works. Electrical energy flows around circuits which are loops made of metal wires. In this game, touching the wire with ...

Ultra-thin layers of silk deposited on graphene in perfect alignment represent a key advance for the control needed in microelectronics and advanced neural network development. After thousands of ...

Kids love building electric circuits, but connecting light bulbs to batteries with fiddly wires is tricky for young hands. Play dough and light-emitting diodes (LEDs) solve the problem beautifully.

Individual silk protein molecules, or “silk fibroins” (blue), are deposited on a graphene surface surrounded by water (green and red spheres) and grow into an atomically precise two-dimensional (2D) ...
