Here, we demonstrate the use of phospholipid micelles to enhance O concentrations by two-fold at the surface of a bilirubin oxidase biocathode. Specifically, 1,2-diarachidoyl-sn-glycero-3-phosphocholine was used in a glucose enzymatic fuel cell to limit power losses due to O transport, even in a quiescent solution.

Molecular imprinting is the process by which molecules are imprinted into the matrix of a material through non-covalent bonding, including hydrogen bonding and van der Waals interactions. In this study hydrogels were imprinted with glaucoma medication with the purpose of creating a reusable ocular drug delivery device with reversible binding sites. The material was synthesized and tested with UV-Vis spectroscopy to determine the concentration of the released drug after twelve hours in distilled water. Modifications were made to the polymer to explore methods required for the proper delivery of the drug over an adequate period of time.

Testing the properties of ski base treatments is a challenging task because there are many environmental conditions and user preferences associated with both the testing and performance outcomes. In this work, we present a method for testing the coefficient of friction, and how it changes over repeated ski runs. We develop a ski track system to control the slope and geographic topography of the testing site, and we use video analysis techniques to calculate the change in the coefficient of friction across three ski runs. We have found an increase in the coefficient of friction after repeated ski runs, which indicates that there is some abrasion of the ski base treatments with repeated testing.
