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.

The Honors project is potentially the most valuable component of an Honors education. Typically Honors students choose to do their projects in their area of study, but some will pick a topic of interest unrelated to their major.
The Honors Program requires that the project be presented at a poster presentation event. Poster presentations are held each semester. Most students present during their senior year, but may do so earlier if their honors project has been completed.
This site presents project descriptions and selected posters for Honors projects completed since the Fall 2015 semester.

Abstract
Resonant sensors are used to detect and measure wave frequency and have many industrial applications that are just beginning to be explored. The Resonant Sensor: DuPont and Smart Surface project is a groundbreaking research project that is headed by Dr. Nigel Reuel, a professor in the Department of Chemical Engineering at Iowa State University. The project also includes a partnership with DuPont and other university faculty members. My work in the spring of 2019 was done as a sub-project of this overarching research venture and involved using these resonant sensors to observe enzyme activity in soil. Being able to use resonant sensors to monitor enzyme activity opens the door to using these sensors in other industrial applications due to their ability to be used cheaply, effectively, and in compact spaces. The presented work analyzed the effects of measuring the resonant signal under differing conditions, such as how far the resonator is buried underground and the amount of water present in the soil. The project also included optimization of the experimental design in order to collect meaningful data and the solving of real-time problems as they came up during the project. The project delivered meaningful results and helped push the research project along as it continues its groundbreaking research.
