Carbon dioxide isn’t the only product of the combustion of gasoline. Sulfur dioxide can also form at high temperatures in the combustion chamber. In the atmosphere, oxidized with nitrogen oxide, can form sulfuric acid, which comes […]

While Li-ion technology is fine for laptops and mobile devices, the inherent density limitation of Li-ion batteries has made the adoption of electric vehicles [EV] difficult. Aside from the density […]
