Thermal Degradation of PC and PA6 During Laser Transmission Welding (LTW)
(2013-09-28)In laser transmission welding (LTW), a laser beam passes through the laser-transparent part and is absorbed by carbon black (CB) in the laser-absorbent part. This causes a temperature rise at the interface between the parts ... -
Thermoplastic-based conductive composites containing multi-wall carbon nanotubes aligned under the application of external electric fields
(2014-11-05)The objective of this thesis is to prepare thermoplastic/multi-wall carbon nanotubes (MWCNTs) and to apply external alternating current (AC) electric fields to achieve enhanced conductivity and dielectric properties. The ... -
Tissue-specific bioscaffolds for adipose-derived stem/stromal cell expansion and delivery
(2016-07-29)Decellularized adipose tissue (DAT) is a promising biomaterial for soft tissue regeneration, and it provides a highly conducive microenvironment for human adipose-derived stem/stromal cell (ASC) attachment, proliferation, ... -
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 ... -
The Treatment of Benzene, Toluene, Ethylbenzene and o-Xylene Using Two-Phase Partitioning Bioscrubbers
(2009-08-20)This thesis examined the biological treatment of gas streams containing benzene, toluene, ethylbenzene and o-xylene (BTEX) using solid-liquid two-phase partitioning bioscrubbers (SL-TPPBs). SL-TPPBs consist of a cell ... -
Ultrasonically Enhanced Mass Transport and Degradation of Polycyclic Aromatic Hydrocarbons in Solid-Liquid Two Phase Partitioning Systems
(2009-09-04)The remediation of soil contaminated with polycyclic aromatic hydrocarbons (PAHs) is endorsed by environmental protection agencies worldwide. Recent studies demonstrated the removal of these contaminants from soil utilizing ... -
The use of high pressure carbon dioxide for in situ product recovery of butyric acid in a two phase partitioning bioreactor
(2014-08-21)The production of organic acids in solid-liquid two-phase partitioning bioreactors (TPPBs) is challenging, as acids absorb into amorphous polymers only in their undissociated form. Thus, at near-neutral fermentation pH ... -
Use of Spatially Non-Uniform Electric Fields for Contact-Free Assembly of Three-Dimensional Structures from Colloidal Particles
(2012-01-31)In this thesis, three specific research contributions to the use of non-uniform electric field driven colloidal assembly are described. The first relates to experimental work using dielectrophoretic and electrohydrodynamic ... -
Using Microfluidics to Study Magnetotactic Bacteria
The purpose of this thesis was to investigate the swimming behavior of magnetotactic bacteria 1) in flow conditions and 2) in porous media; and further 3) to exploit their unique characteristics towards bio-actuation of ... -
Variance Analysis for Nonlinear Systems
(2007-06)In the past decades there has been onsiderable commercial and academic interest in methods for monitoring control system performance for linear systems. Far less has been written on control system performance for nonlinear ... -
Water Sorption Properties of Sub-Micron Thin Ionomer Films
(2016-02-25)This thesis is focused on the water uptake and swelling properties of sub-micron thin ion conducting polymer (ionomer) films. One motivation for this work stems from the need to resolve the discrepancy between high water ... -
Weld Read-Through Defects in Laser Transmission Welding
(2010-07-02)In laser Transmission Welding (LTW), the laser beam passes through the transparent part and is dissipated as heat in the absorbent material through the use of laser-absorbing pigments such as carbon black (CB). This energy ...
