Pure research is prepared to gain knowledge for the sake of knowledge itself. Molina as well as Rowland's research on the behavior of CFCs- showing that in the lab CFCs could speed up the breakdown of ozone-was motivated by their curiosity and is an instance of pure research. Applied research is carrying out to solve a specific problem. Scientists are conducting experimentation to find chemicals to replace CFCs. These experiments are instance of applied research.
