Development of a solid-phase extraction method for the separation of algal lipid classes
Algal oils have been extensively used as feedstocks for the production of biodiesel. These can be obtained using one of several extraction techniques, such as Soxhlet extraction. A critical issue is the presence of compounds ... -
Sequential Model-Based A- and V-Optimal Design of Experiments for Building Fundamental Models of Pharmaceutical Production Processes
(Elsevier BV, 2019-07-02)Sequential model-based A- and V-optimal experimental designs are known to be effective for maximizing the information content of data, leading to reliable parameter estimates and model predictions. A- and V-optimal designs ... -
Extractable content of functional acrylic resins produced by radical copolymerization: A comparison of experiment and stochastic simulation
(Elsevier BV, 2019-12-15)A comprehensive stochastic simulator that considers all probable secondary reactions essential for the description of high-temperature radical copolymerization of acrylate/methacrylate is implemented based on previously ... -
Electrokinetic Assembly of Nanoparticles for Surface-Enhanced Raman Scattering-Based (Bio)Chemical Sensing
Surface-enhanced Raman scattering (SERS) enables sensitive detection of (bio)chemical analytes. However, the need for nanostructured noble metal substrates poses a major obstacle to its application. In this thesis, we ... -
Exploiting the Unique Plasmonic Phenomenon of Metallic Nanostructures for Sensing and Biosensing Applications
Real-time, accurate sensing promoted by analytical sensors is extremely important for advances in drug discovery, disease diagnosis and for studying biological systems. In particular, label-free surface plasmon resonance ... -
Startup Steady Shear Flow from the Oldroyd 8-Constant Framework
(2019-01)One good way to explore fluid microstructure, experimentally, is to suddenly subject the fluid to a large steady shearing deformation, and to then observe the evolving stress response. If the steady shear rate is high ... -
Hydrodynamic Interaction for Rigid Dumbbell Suspensions in Steady Shear Flow
(2018-12)From kinetic molecular theory, we can attribute the rheological behaviors of polymeric liquids to macromolecular orientation. The simplest model to capture the orientation of macromolecules is the rigid dumbbell. For a ... -
Modulating the Inflammatory Response of Macrophages on Biomaterial Surfaces
The foreign body response is an inflammatory response to implanted materials and poses significant challenges for biomaterials-based medical applications, often leading to the degradation or fibrous encapsulation of an ... -
An Efficient Process for the Cu(0)-Catalyzed Controlled Radical Synthesis and Subsequent Chain Extension of Poly(Methyl Acrylate) Macroinitiator
Copper mediated polymerization is used to produce poly(methyl acrylate) with an average degree of polymerization of 10 (P(MA)10) and narrow distribution in both batch and continuous tubular reactors at ambient temperature. ... -
The biological treatment of synthetic fracking fluid in an extractive membrane bioreactor: Selective transport and biodegradation of hydrophobic and hydrophilic contaminants
(2019-06-05)The biodegradation of selected organic constituents present in hydraulic fracturing wastewater were examined in an extractive membrane bioreactor (EMB) operating with Hytrel™ 3548 tubing. Synthetic hydraulic fracturing ... -
Reversible Photoisomerization from Borepin to Boratanorcaradiene and Double Aryl Migration from Boron to Carbon
(2019-03-26)B(npy)Ar2 (npy=2-(naphthalen-1-yl)pyridine) compounds bearing various nonbulky aryl groups undergo a clean and sequential two-step photoisomerization in which two aryl substituents on boron migrate to a carbon atom of the ... -

This thesis proposes strategies to improve the crystallinity and mechanical properties of poly(lactic acid) (PLA) and investigates the effects of these modifications on hydrolytic degradation. The effect of long-chain ... -
Molecular Continua for Polymeric Liquids in Large-Amplitude Oscillatory Shear Flow
(2017-05)In this paper, we connect a molecular description of the rheology of a polymeric liquid to a continuum description, and then test this connection for large-amplitude oscillatory shear flow (LAOS). Specifically, for the ... -
Simple Accurate Expressions for Shear Stress in Large-Amplitude Oscillatory Shear Flow

Ethermodynamic Instability of Polymeric Liquids in Large-Amplitude Oscillatory Shear Flow from Corotational Maxwell Fluid
(2018-04)When polymeric liquids are subjected to oscillatory shear flow, if the amplitude of the shear rate is high enough, the shear stress response will become aperiodic. This has been variously attributed to fracture, common ... -
