The function of the Department of Chemical and Biological Engineering has been to prepare students for the study and application of chemistry in industry. This focus has included preparation for employment in various industries as well as the development, design, and operation of equipment and processes within industry.Through the CBE Department, Iowa State University is nationally recognized for its initiatives in bioinformatics, biomaterials, bioproducts, metabolic/tissue engineering, multiphase computational fluid dynamics, advanced polymeric materials and nanostructured materials.
History
The Department of Chemical Engineering was founded in 1913 under the Department of Physics and Illuminating Engineering. From 1915 to 1931 it was jointly administered by the Divisions of Industrial Science and Engineering, and from 1931 onward it has been under the Division/College of Engineering. In 1928 it merged with Mining Engineering, and from 1973–1979 it merged with Nuclear Engineering. It became Chemical and Biological Engineering in 2005.

Abstract
Cellulose, furfural, and lignin can be produced in one process from hemp hurds or corncobs at a reasonable cost. Plastics and ion-exchange resins were prepared from the lignin and cellulose. A cement additive was made from the hemp lignin which improved the flow of freshly mixed cement and increased the strength of the cement after setting. An equation for the prediction of index of refraction from chemical structure was developed. The index of refraction equation was used to calculate atomic radii. Another equation was derived, from the mechanism used in the derivation of the index of refraction equation, which explained the behavior of light in moving mediums. One of Freudenberg's proposed structures of lignin was verified with the index of refraction equation.
