Using an oil and gas industry’s byproduct, the team worked with uniquely shaped carbon materials — tiny cones and discs — with a pure graphitic structure. These unusual forms produced via ...

The innovative solution uses uniquely shaped carbon materials — tiny cones and discs — with a pure graphitic structure to impact electrochemical energy storage technologies. A team led by ...

The cup and cone structure of the pair of bearings allows the shaft to self align so that there is no unwanted lateral force on the pedal body. Modern pedals may have sealed bearings at each end.
