A modern scientific team has replicated Thomas Edison’s light bulb experiment and discovered it can produce graphene, a material unknown in his time. Using Raman spectroscopy, researchers confirmed ...

Every biography of Edison talks about how the secret to the incandescent lamp was to remove the air from the bulb. That’s true when you use conventional filaments, but a man named Nernst found that ...

Early carbon light bulbs may have produced graphene, since applying voltage to carbon filaments mirrors what is now called flash Joule heating. Graphene is a transparent, remarkably strong substance, ...

Researchers in the US have uncovered evidence suggesting that Thomas Edison may have accidentally produced graphene over a century before it was formally identified, while developing his first light ...
