Proteins are long chains of amino acid residues that perform a myriad of functions in living organisms, including enzymatic reactions, signalling, and maintaining structural integrity. Protein function is determined directly by the protein structure. X-ray crystallography is the primary technique for determining the 3D structure of proteins, and facilitates understanding the effects of protein structure on function. The first step towards structure determination is crystallizing the protein of interest. We have developed a centrifugally-actuated microfluidic device that incorporates the fluid handling and metering necessary for protein crystallization. Liquid handling takes advantage of surface forces to control fluid flow and enable …

Anaerobic Digestion: Awareness, Implementation, And Simulation, Kieran Tay, Nicholas Sbalbi, Michael Forozis, Flo Sabatini

Student Showcase

Anaerobic digestion (AD) is the process in which organic matter is fermented in an oxygen-deprived environment to produce renewable biogas. Our project is multi-faceted, with the overall goal of raising public awareness of AD as a transitional energy source. To that end, our group has named itself Undergraduates Raising Awareness for Anaerobic Digestion (URAAD). We are approaching this goal on three fronts, including (i) a website, (ii) a physical lab-scale digester, and (iii) a computer simulation of anaerobic digestion.

The first component, the website, was developed with the aim of serving as a resource for the public. It includes educational …
