Metal Corrosion : Metal Corrosion Aluminum and Zinc Corrode but do not flake Once covered with oxide, protected Metal Corrosion : Metal Corrosion Paint the steel Small scratches expose iron to rusting Repaint or wax shut the scratch Galvanization Coat iron with zinc Zinc protects itself and thus protects the iron Metal Corrosion : Metal Corrosion Steel too large to coat with zinc Add a piece of zinc Oxidizing agent takes electron Steel will conduct electrons Zinc touching steel anywhere will lose electrons Chemiluminescence : Chemiluminescence the emission of light with limited emission of heat (luminescence) result of a chemical reaction takes place in living organisms Bioluminescence American firefly Chemiluminescence : Chemiluminescence Uses detection and quantization of biomolecules in assay systems DNA sequencing using pyrosequencing Lighting objects. Chemiluminescent kites, emergency lighting, glow sticks (party decorations). You do not have the permission to view this presentation.
