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
Dissolved oxygen levels in biological processes depend on the biological, chemical, and physical properties of the process being monitored. The analysis of dissolved oxygen concentration is a key test for process control and optimization. A review of the measurement methods for dissolved oxygen concentrations will be presented in this paper. Included in this review are the chemical, volumetric, tubing, electrochemical electrode, and optode methods. Advantages and disadvantages of these methods are discussed and key considerations for their use are summarized.
