That’s pretty good, but nowhere near the 15 kilovolts needed for a self-sustaining arc across electrodes placed 5 mm apart. A little math told him that he could achieve this by rewinding the ...

When mixed together, the two powders are heated in a graphite crucible using an arc welder with a carbon electrode. The crucible appears to be made from an EDM electrode; we’ve seen them used ...

While the study uses everyday wholemeal bread from the grocery store, creating the electrode requires a furnace capable of ...

A trio of engineers from Saint Vincent College and the University of Pittsburgh has developed two unique ways to mold ...

New techniques allow for shaping bread-derived carbon electrodes, enhancing their potential for sustainable applications.

The electric arc type works by funnelling a current through electrodes into the furnace, which is less energy-intensive than blast furnace production and removes the need for high carbon-emitting ...
