Nafion is a sulfonated tetrafluoroethylene based fluoropolymer-copolymer discovered in the late 1960s by Walther Grot of DuPont. It is the first of a class of synthetic polymers with ionic properties which are called ionomers.his form of Nafion, referred to as the neutral or salt form, is finally converted to the acid form containing the sulfonic acid (-SO 3 H) groups. Nafion can be cast into thin films by heating in aqueous alcohol at 250 Â°C in an autoclave.
Antarctic Ecosystem: Abundance of Life Diatoms like these are at the base of the Antarctic food chain. In summer they use photosynthesis to grow, and multiply into huge populations. Young (juvenile) krill that were collected in a net. A curious Emperor penguin approaches a technician.
Much less extensive than Arctic tundra, Antarctic tundra is found on the Antarctic Peninsula and several Antarctic and subantarctic islands. These areas have rocky soil that supports minimal plant life: two flowering plant species, mosses, algae, and lichens.ife in any biome includes producers (plants and other photosynthetic organisms) and consumers (organisms that obtain their energy from producers). These consumers may be further classified as herbivores (plant eaters), carnivores (meat eaters), or omnivores (feed on a combination of animals and plants).
