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:

Pollutant	1970 Emissions	1990 Emissions	CA ultra-low emissions
C_xH_y	1.5 g/mile	0.25 g/mile	0.04 g/mile
CO	15 g/mile	3.4 g/mile	1.7 g/mile
NO_x	3.1 g/mile	0.4 g/mile	0.2 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?
