Research Description By Graduate Engineering Department

Biological Systems Engineering

Research is conducted in five focus areas:

Bioengineering for health and productivity
Environmental engineering
Bioprocess engineering for adding value
Site-specific crop management
Water resources and ecosystems engineering

Research endeavors are a valuable component of our mission to the students, faculty, state, region, and world. Research is conducted in university labs, and in the field utilizing four Research and Extension Centers located throughout Nebraska. In addition to research conducted in Nebraska, faculty have also worked overseas in developing agricultural and irrigation systems of benefit to specific locales. Students have the opportunity to be involved in faculty research as part of their education, or to develop research in areas of their own interest.

Chemical and Biomolecular Engineering

Biological Process Development Facility
The BPDF develops vaccines and biotherapeutics derived from recombinant yeast and bacterial expression systems under current Good Manufacturing Practices and Good Laboratory Practices.

Bioseparations and Biomaterials Group

The ability to manipulate the strength and specificity of protein-binding or cell-substrate events provides a tremendous leverage for the development of novel biological products and processes at a molecular level. I am motivated by the desire to solve problems in biology and medicine, and the challenge to develop models and systems based on scientific and engineering principles as applied to biological systems. My broad interests include the areas of bioseparations, biomaterials and functional tissue engineering.

We are primarily interested in better understanding the role of matrix architecture and matrix mechanical properties on the biosynthetic activity and metabolic activities of chondrocytes that are seeded and maintained on such scaffolds. Another area of active research interest in my laboratory is in the area of bioreactors for the development of engineered tissues. We are developing bioreactors that use stimulation via ultrasonics that seek to induce cell growth and proliferation.

Additionally, we are also interested in understanding the cellular mechanisms under ultrasound stimulation. In the area of biomaterials, we are developing surface treatment strategies that passivate platelet responses to implanted biomaterials by selective protein adsorption and also developing surfaces that mimic the anticoagulant pathways found on native endothelial surfaces.

Laboratory for Dynamic Materials Characterization

This laboratory is for studying the dynamic response of materials subjected to impulsive, high strain-rate loadings. The laboratory contains Kolsky (or split-Hopkinson) torsion and compression bars as dynamic loading devices. These apparatuses can produce a rapid rising, trapezoidal pulse of torsion, compression or tension loading, or a combination of these loading pulses. Both the delivery of dynamic loading to a test sample and the result of the sample material response to the loading are in the form of linear elastic stress waves propagating within two long metallic bars (elastic waveguides) and can be determined accurately by analyzing time-resolved measurements of the profiles of these waves in the bars.

Such measurements are obtained using a state-of-the-art electronic system consisting of high-impedance, precision strain gauges, a 12-bit high-resolution digital oscilloscope with multi-channel differential amplifiers, and a PC workstation with control software for automated data acquisition. The experimental technique enables various materials of interest (including ceramics, metals, and polymer melts) to be examined under well-defined dynamic loadings. The following are some of the ongoing projects in the laboratory:
1. Transient Rheometry of Polymer Melts at High Shear Rates

A novel polymer melt rheometer has been developed by incorporating a cone-and-plate rheometric cell and a thermal chamber into the Kolsky torsion bar device. The impulsive loading delivered in the form of guided torsional stress wave pulse can drive the new rheometer to an angular sliding velocity as high as 1600 rad/s in a time less than 100 ms, thus enabling measurements of the transient, large-deformation rheological response of polymer melts at shear rates up to 10000 1/s, shear strains up to 10, and temperatures up to 300 °C. This new technique is currently used to characterize the viscoelastic response of a branched low-density polyethylene melt under high-rate and large-strain shearing deformations. The results are useful for improving the material modeling in computerized analysis and design of the manufacturing processes involving rapid flows of the material, e.g., injection molding and extrusion.

2. Dynamic Tribometry of Fracture Surfaces

A dynamic tribometer has been developed by adding a compression unit into the conventional Kolsky torsion bar device. The modified apparatus produces combined loadings of dynamic compression and torsion, thus providing a new technique for dynamic tribometric experiments at sliding velocities up to 10 m/s and compressive contact stresses up to 1 GPa. This technique is being used in the research work sponsored by the U.S. Army Research Office to investigate the dynamic frictional resistance between closed fracture surfaces. Tribo-pairs formed by pre-fractured specimens are tested under various contact stresses and sliding velocities. The tribometric results are studied in conjunction with the statistical characterization of the fracture surface topography in an attempt to develop an understanding of whether and how a micro- fractured material under high confining stresses can resist dynamic deformation. This scientific issue is important for material and structure designs of advanced armors, particularly those involving the use of hard and brittle solids such as ceramics and ceramic composites.

Land Measure & Surveying Lab

Mid-America Transportation Center

The states that comprise Region VII (Iowa, Kansas, Missouri and Nebraska) have many commonalities and, not surprisingly, the states' respective transportation agencies face many similar issues in providing a safe, efficient and effective transportation infrastructure. For example, the majority of the region's roadway networks are primarily rural, although there are a number of major cities interspersed throughout the area that face traditional urban transportation problems. In addition, the four states experience a considerable amount of freight traffic on the region's roadways, railways and waterways - all of which are located at the crossroads of the nation's transportation system. In Region VII, interstates I-70 and I-80 are vital east-west corridors and interstates I-35 and I-29 are major north-south corridors. Given the region's diverse economy and the growing trade with China, Mexico and Canada, freight traffic is increasing every year and is having a profound effect on the region's infrastructure. Congestion on the roadways, railways and waterways caused by this additional freight traffic will have an increasingly detrimental effect on the safety of the region's citizens, the traveling public, the transportation infrastructure and the region's economy.

The interdisciplinary areas of expertise required to successfully meet the research, education and technology transfer objectives associated with our theme include risk and reliability analysis, structural analysis, materials engineering, transportation system operations and alternative transportation infrastructure financing. MATC will work with the leading faculty members from multiple academic departments of the consortium universities. These academicians will partner with staff from the state transportation agencies and members of the commercial freight industry; engineers from the partner organizations will add comprehensive knowledge to minimize the risk to the critical infrastructure systems of the region (and, by extension, of the nation). This collaboration is established to foster an intellectual climate and physical environment capable of supporting the increasing need to improve safety and reduce risk on the multi-modal transportation system.
