These devices, called etalons, exhibit optical properties that depend on many characteristics, primarily temperature. Temperature is the most basic property of pNIPAm-based microgels, as it changes their solvation state. In this study, we modified pNIPAm-based microgels with 3-aminophenylboronic acid (APBA), which renders them responsive to glucose; i.e., they change size in a glucose-dependent fashion. By modifying the Au surface of a quartz crystal microbalance (QCM) with etalons composed of these microgels, we can make QCM-based devices that shift frequency as a function of glucose concentration in buffer solution. Again, this is a result of the microgels’ changing solvation state in response to glucose. It was determined that glucose-responsive pNIPAm microgel-based QCM can be used as a glucose sensor. This dissertation will detail the work done on these systems

The removal of solid particulates from crude oils and hydrocarbon streams is a common challenge in refining. Finding a method for efficient removal of the suspended solids in the oil streams is the main objective of this work. Paraffinic and aqueous treatment and the combination of these two...
