ZIF-71/PDMS Mixed Matrix Membranes for Acetone-Butanol-Ethanol Separations by Pervaporation

Zeolitic imidazole frameworks (ZIF) are known to improve membrane performance in biofuel separation. This research studies ZIF-71/polydimethylsiloxane (PDMS) mixed matrix membrane performance in pervaporation of acetone-butanol-ethanol (ABE) solutions. Membranes with 0, 25, 40, and 60 weight percent (wt%) ZIF-71are synthesized and tested with model solutions of ABE. The results show that 40wt% is the optimal […]

Parametric Design Optimization of Multi-Functional Honeycomb Structures for Additive Manufacturing

The objective of this research is to develop a methodology to extract optimal design parameters (cell wall thickness and the corner radius) in hexagonal honey-comb structures using finite element modeling, response surface methodology and optimization techniques to achieve multi-functional objectives. In this work, the researcher will look at combining the objectives of mechanical stiffness with […]

Compact Terahertz Real-Time Imaging System

The objective of this work is to design a low-profile compact Terahertz (THz) imaging system that can be installed in portable devices, unmanned aerial vehicles (UAVs), and CubeSats. The proposed system relies on a novel image reconstructing technique that allows high spatial resolution imaging using a variety of elements. Two different antenna array designs are […]

Bioresponsive Copolymers of Poly(N-isopropylacrylamide) with Enzyme-Dependent Lower Critical Solution Temperatures

Enzyme-degradable hydrogels are desirable for drug delivery and tissue engineering applications because they mimic biological systems. The aim of the project was to synthesize and characterize injectable, bioresponsive and bioresorbable poly(NIPAAm)-based copolymers with enzyme-degradable side chains. These copolymers may be useful for applications such as enzyme-triggered drug delivery and bioresorbable scaffolds for tissue engineering. The […]

Porous Silica Films as Thermally Insulating Coatings on Windows

The deposition of transparent, porous silica films as thermally insulating coatings on windows will help reduce energy costs in buildings and homes. 90% porous silica has been characterized for its thermal and optical properties showing surprisingly low conductivities compared to estimates. Film adhesion, stress, and transparency have shown to be major hurdles during the development […]

Reductive Dechlorination of Trichloroethene Sustained by Microbial Chain Elongation

The objective of this research is to test the effectiveness of a novel approach for bioremediation of trichloroethylene (TCE) in soil and groundwater. This approach consists of reducing TCE to non-chlorinated, non-toxic ethene by utilizing the electron donor hydrogen produced from microbial chain elongating (MCE) cultures. Results thus far showed that TCE-reductively dechlorinating microorganisms can […]

Modeling Extra Cellular Matrix (ECM) Re-organization Due to Cell-ECM Mechanical Interactions

This research focused on the systematic investigation of cell-ECM mechanical interactions through quantitative examination of 165 high-resolution time-lapse data of multi-cellular systems of collective cell migration. The researcher then focused on developing a computational model simulating the dynamic force network in ECM generated by contracting cells. The interaction model of cancer cell protrusions, and the […]

Norepinephrine and Adenosine Infused Microparticles for Brown Adipose Tissue Stimulation

The objective for this semester is to develop and optimize a protocol that consistently fabricates biodegradable microparticles of the correct dimensions, surface morphology, and narrows size distribution via fluid dynamics. This objective is being completed via proof-of-principle experiments and a DOE study. The proof-of-principle experiments allow for the exploration and proof of concept while the […]
