CASE STUDY
Vanadium pentoxide nanoparticles mimic natural enzymes and inhibit surface build-up of algae and bacteria.
Johannes Gutenberg University Mainz (JGU) in Germany.
According to Lloyds, this means an increase in fuel consumption of up to 28 percent and about 250 million tons of additional CO2 emissions per year.
