Adaptation Of Scenedesmus Dimorphus To Brackish Water, Dustin Bowden, Joanne M. Belovich Sep 2013

Adaptation Of Scenedesmus Dimorphus To Brackish Water, Dustin Bowden, Joanne M. Belovich

Undergraduate Research Posters 2013

Microalgae is a promising biofuel feedstock for replacement of conventional transportation fuels. Microalgae does not require arable land for cultivation, and the biofuel production rate per acre of land is an order of magnitude greater than that needed for crop-based production methods. Though microalgae to biofuel processes are attractive, none have proven commercially successful due to the high costs of algae dewatering. Moreover, the scarcity of fresh water in many parts of the world prevents development of this process because of competition with drinking water supplies. Our lab has developed an efficient dewatering method using an inclined gravity settler. It ...


Design Optimization Of An Above-Knee Prosthesis With Energy Regeneration, Taylor Barto, Holly Warner, Rick Rarick, Dan Simon Sep 2013

Design Optimization Of An Above-Knee Prosthesis With Energy Regeneration, Taylor Barto, Holly Warner, Rick Rarick, Dan Simon

Undergraduate Research Posters 2013

Above-knee amputees who use a prosthetic leg typically have to compensate for its shortcomings with unnatural hip motions. This compensation eventually leads to adverse health issues such as arthritis. We propose an active prosthesis to improve performance. The motor in our prosthetic knee allows the patient to move his hip normally, thus reducing the possibility of ancillary health issues. To improve the efficiency of the prosthesis, we use the braking phase of the prosthesis to regenerate energy. By storing energy in a supercapacitor during braking, the prosthesis lasts longer between each charge than it would without regenerative braking. We are ...

Center for Biorenewable Chemicals Annual Reports

In the U.S., the production of industrial chemicals is a $400 billion-plus enterprise that impacts all aspects of society from personal care products to building materials. Unfortunately, this vital industry is not self-sustaining; its long-term future is predicated on transitioning from current nonrenewable, petroleum feedstocks to renewable biobased feedstocks. The development of conversion technologies needed to facilitate this transition is the focus of the NSF Engineering Research Center for Biorenewable Chemicals (CBiRC).
