Abstract
This research is focused on improving the design of vials for cryopreservation. Traditional vials used for cryogenic storage of biological specimens such as blood and cells are generally constructed out of plastic or glass and can be sealed to offer a pathogenic barrier. The vials also are transparent and of low cost. Unfortunately, they have poor heat transfer characteristics. Of particular note is the relatively low thermal diffusivity of biological samples and the cylindrical geometry employed by current vials creates a spatially non-uniform cooling environment. This leads to spatially non-uniform cooling rates of the samples.
Darnell Cage hails from Saint Louis, MO and is currently a freshman undertaking Mechanical Engineering with an Aerospace emphasis at the University of Missouri - Columbia (Mizzou). He is working with Dr. Gary Solbrekken and the Mechanical Engineering department of the College of Engineering on his research entitled "Numerical Simulations and Experimental Evaluations of Heat Transfer Performance of Improved Cryogenic Vials for Cryopreservation". At Mizzou, Darnell is involved in the Mizzou Black Male's Initiative, National Society of Black Engineer, American Society of Mechanical Engineers, and Diversity in Engineering. He is also a George C. Brooks scholar, Diversity in Engineering scholar, Chamber's scholar in engineering, Gates Millennium scholar, William L. Clay scholar, and William Pablo Feraldo scholar. This summer, he plans to intern with Pratt and Whitney in Middleton Connecticut. After graduating with his Bachelor's degree in Mechanical Engineering, he plans to attend graduate school to further his education with hopes of opening his own engineering firm.
