Metal-organic framework thin film synthesis via a microfluidic pen system

Creator:: Chang, Victoria
Abstract:: ZIF-8, a zeolitic imidazolate framework that consists of zinc ions and imidazolate linkers, is of great interest due to its simple synthesis methods, low-cost raw materials, chemical and thermal stability, as well as its stability in moist environments. Furthermore, due to its unique structure, it contains well-defined pores that have...

Intensification of Solvent Extraction in an Additively Manufactured Microfluidic Separator

Creator:: Touma, Jad George, Coblyn, Matthew, Freiberg, Lucas Joseph, Kowall, Cliff, Zoebelein, Avaline, and Jovanovic, Goran Nadezda
Abstract:: Solvent extraction is an integral chemical and biochemical separation process that is drastically intensified in microfluidic systems. A novel high-throughput micro-separator was additively manufactured for the intensification of liquid–liquid separation. The micro-posts array within the flow plate generated a capillary pressure gradient on the non-wetting organic phase, enabling continuous, membrane-free,...

Reversible Covalent Binding of Desferrioxamine B (DFOB) to 2 Polystyrene Microspheres for the Chelation of Aqueous Iron Citrate

Creator:: Touma, Jad G., Kelly, Christine, Coblyn, Matthew, Jovanovic, Goran N., and Schilke, Kate
Abstract:: Desferrioxamine B (DFOB) was reversibly and covalently conjugated to polystyrene microspheres via N-succinimidyl 3-(2-pyridyldithio)propionate (SPDP) crosslinker. DFOB retained post-immobilization activity with at least 89% able to bind Fe(III)-citrate under pH 7.4 and a citrate:iron molar ratio = 100:1. Comparing iron capture by DFOB-activated beads and sulfhydryl (−SH) control beads demonstrated...

Development of Rapid Diagnostic Tools for Personal Health Monitors in the Context of Therapy Monitoring

Creator:: Wentland, Lael T.
Abstract:: Personal health monitoring tools, a subset of point-of care-diagnostics, enable more frequent testing of chronic health conditions outside of a clinic setting and can inform personalized therapy or support telehealth diagnostic capabilities. While there is evidence that regular monitoring of chronic conditions can lead to better health outcomes and lower...

Growth, Characterizations, and Applications of Patterned Nanostructured Thin Film

Creator:: Gao, Zhongwei
Abstract:: A unique microreactor-assisted nanomaterial synthesis and printing process was studied for the fabrication of patterned metal oxide nanostructured thin films. The process uses a continuous flow microreactor to control and generate a reactive chemical flux that was transported to a patterned microfluidic channel. The microreactor-assisted nanomaterial synthesis process can generate...

Data-driven imputation of miscibility of aqueous solutions via graph-regularized logistic matrix factorization

Creator:: Behnoudfar, Diba, Simon, Cory M., and Schrier, Joshua
Abstract:: Aqueous, two-phase systems (ATPSs) may form upon mixing two solutions of independently water-soluble compounds. Many separation, purification, and extraction processes rely on ATPSs. Predicting the miscibility of solutions can accelerate and reduce the cost of the discovery of new ATPSs for these applications. Whereas previous machine learning approaches to ATPS...

A Graph Grammar Representation of Metal-Organic Frameworks for Computational Synthesis and Exploration

Creator:: Geringer, Mark K.
Abstract:: In this work, metal-organic frameworks (MOFs) are computationally represented, generated, and evaluated. The organic linker molecules are represented as graphs and use graph grammars where the atoms are represented by nodes and the bonds are represented by arcs. The grammar rules that dictate the graph generation process work on the...

Structure-Property Relationships of Supported Palladium and Rhenium Oxide for the Alkane Rearrangement of Hydrocarbons and Deconstruction of Polyethylene via Tandem Dehydrogenation and Olefin Metathesis

Creator:: Moore, Selena C.
Abstract:: The rapid accumulation of plastic waste in landfill, waterways and oceans is becoming a critical problem, one that current recycling technologies are not capable of solving. Recent proposed approaches in the depolymerization of waste plastics employ an Olefin-Intermediate Process (OIP), where feedstocks like polyolefin plastics are ‘activated,’ producing an olefin...

Addressing the Risks of Nanoscale Polymers: Exposure, Behavior, and Toxicity

Creator:: Stine, Jared
Abstract:: Nanoscale polymers (including nanoplastics) are widely present through commerce and make their way into the environment. As the improper disposal of plastic waste leads to continued accumulation and degradation of plastic pollution, the presence of plastic particles less than 1 micron (μm) in size (nanoplastics) will increase. Heightened concern over...

Signal Enhancement in Lateral Flow Tests for Infant HIV Diagnosis

Creator:: Rodriguez, Michael A.
Abstract:: Paper-based assays for HIV diagnosis are cheap, portable, and require little to no skilled training, electricity, or expensive equipment to perform successfully. However, there is a need for tests with lower limits of detection (LOD) for diagnosing infection at the earliest stages. Effective labeling to increase signal-to-noise ratio is critical...
