Applied science is about using the findings of science to apply it, and to solve problems. In the natural sciences, this is done by engineering. In sciences such as psychology, this can mean that theoretical findings are used to improve a test method, for example.
Applied research is generally done to solve a problem. Certain refrigerants escape into the atmosphere and damage the ozone layer. Development of new refrigerants is an example of applied research. This work not driven by a desire to know, but by a desire to solve a specific problem.
