Electrical Double Layer in Polar and Nonpolar Media in the Presence of Surfactants
The objective of this thesis is to improve our understanding of the concept of electrical double layer (EDL). The EDL is the basis of all electrokinetic phenomena. Despite numerous studies in the span of over a century, ... -
Using poly(vinyldodecylimidazolium bromide) for the in‐situ product recovery of n‐butanol
(Wiley, 2019)The mitigation of end‐product inhibition during the biosynthesis of n‐butanol is demonstrated for an in‐situ product recovery (ISPR) system employing a poly(ionic liquid) (PIL) absorbent. The thermodynamic affinity of ... -
Towards Improved Process Development for Biolubricant Production from Vegetable Oils
Biolubricants are lubricants with a base oil produced from biological feedstock. Ester-based biolubricants enjoy the most widespread commercial use, even though complex chemical modifications are required to improve their ... -
An Investigation of Antimicrobial Properties of Grafoid Inc. Graphene Coatings
Graphene materials have been the center of attention due to their physicochemical properties. Moreover, in the past decade, these materials have attracted increasing attention because of their antimicrobial properties. A ... -
Molecular Orientation in Large-Amplitude Oscillatory Shear (LAOS) of Complex Fluids
Polymer rheological properties are important to modern manufacturing, and though polymers have been studied for decades, we still do not fully understand how polymers flow. Subjecting a polymeric liquid to oscillatory shear ... -
Model-Based Optimal Design of Experiments with Noninvertible Fisher Information Matrix
In this thesis, different approaches are developed and compared to deal with a noninvertible Fisher Information Matrix (FIM) when designing sequential model-based (e.g., A, D, and V-optimal) experiments. Proposed approaches ... -
