A team of University of Rostock chemists discovered a way to extract hydrogen from methanol at low temperatures and ambient pressures. This […]

However, Grätzel now found a solution for the cells to be cheaper and more efficient. Grätzel’s cells use organic dyes to absorb sunlight, which hits the titanium dioxide […]
