Tribology of gears

Introduction Gears are the mechanical transmission elements that are toothed to transfer the motion and power between any mechanical components. They are widely used in various devices such as automobile parts, clocks, mechanical machines, bicycles, […]

The researchers intend to carry out more research using vanadium as the electrolyte, with practices to protect its oxidation by air. Initial experimentation shows that vanadium can be used and will cycle in a similar manner to the zinc iodide redox system.
