To accomplish this mission, wheel bearings consist of two rotating rings with tiny ball bearings between them. The exterior of the wheel bearing is encased in a sealed waterproof metal housing to ...
In a mixed electrolyte of 1 mol L-1 KOH and 0.1 mol L-1 glycerol, the onset potential of the electrode dropped to 1.16 V RHE, significantly outperforming OER. Rotating ring-disk electrode (RRDE) ...
Perhaps most interesting is the mechanical design on show. A static internal ring is paired with a rotating outer band, presumably with the intention of directing input. There's also an electronic ...
