WebWhat is bromomethane? Bromomethane (also called methyl bromide) is a colorless, odorless gas. Some bromomethane is formed in the ocean, probably by algae or kelp; after it is formed, it is likely to move into Weboxidized to form the quinonediiminium dication.19–21 To the best of our knowledge, this is the first attempt to use TMPD as an EES electrode material. TMPD’s appeal as an EES electrode
