Halting the Briggs-Rauscher Oscillating Reaction   
(Movie/Animation, Audio/Visual (4))
The Briggs-Rauscher reaction is demonstrated in three different ways. Catalase from a liver extract decomposes the hydrogen peroxide in an Briggs-Rauscher reaction, stopping the oscillations.
Factors Affecting Glucose Oxidase Activity   
(Movie/Animation, Audio/Visual (4))
Various factors which affect glucose oxidase activity are demonstrated.
Metallocene Catalyzed Polymerization of Ethylene   
(Movie/Animation, Audio/Visual (3))
Polymerization chemistry is demonstrated by the reaction between ethylene and a Ziegler-Natta catalyst.
Induction by Iron(II) of the Oxidation of Iodide by Dichromate   
(Movie/Animation, Audio/Visual (2))
Acidic aqueous solutions containing dichromate and iodide ions are mixed with no reaction. The addition of a solution of iron(II) ion induces the rapid formation of brown triiodide ion.
Kinetics : CatalyticConverters (4 Variations)   
(Assessment Material (1))
The following table illustrates the changes in emissions requirements for automobiles:
Pollutant1970 Emissions1990 EmissionsCA ultra-low emissions
CxHy1.5 g/mile0.25 g/mile0.04 g/mile
CO15 g/mile3.4 g/mile1.7 g/mile
NOx3.1 g/mile0.4 g/mile0.2 g/mile
Catalytic converters are used in automobiles to convert pollutants in engine emissions to benign products. Catalytic converters in today's automobiles are made of a porous ceramic brick that has been coated with catalysts, additives, stabilizers, and support materials. Corning has developed bricks that have very thin-walled channels with 600 channels per square inch. Which of the following research goals did they target?
