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...

Janus-Type Wicking Microfluidic Devices for Separation and Collection of Plasma from Blood

Creator:: Unitan, Linus J.
Abstract:: A simple Janus-type membrane-based wicking microfluidic device fabricated on a polycaprolactone-filled glass microfiber membrane enables separation and collection of blood plasma or serum from whole blood. This device bridges the wicking and cut-capillary-based solution transport mechanisms in a single membrane. The initial portion of the device is fabricated using selective...

Investigating Influences of Natural and Anthropogenic Lead Sources on Environmental Archives at Multiple Spatial and Temporal Scales: Evidence from Oysters and Ice Cores

Creator:: Wensman, Sophia M.
Abstract:: Environmental archives provide records of natural and anthropogenic variation in the environment at different temporal and spatial scales. Lead (Pb) concentrations and isotopic ratios are useful tracers of anthropogenic emissions from industrial activities including mining, smelting, and leaded gasoline use, however, methods of measuring Pb are largely limited in low...

Formation of hybrid supramolecular assemblies using biological molecules and transition metals

Creator:: Smith, Rachelle M. S.
Abstract:: Naturally occurring assemblies, such as DNA and proteins, utilize intermolecular forces (i.e H-bonding and van der Waals) to assemble. Utilizing these electrostatic interactions has only just started in the past five decades to be a tool used in synthetic chemistry in what is known as supramolecular chemistry. Supramolecular chemistry has...

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...

Polyoxoniobates: fundamental solubility trend and their application in solution and on the surface of thin films

Creator:: Rahman, Tasnim
Abstract:: Polyoxometalates (POMs) are anions consisting of three or more early transition metals ™ (Gr V and VI) oxoanions (in their highest oxidation state) linked together by a shared oxygen bond to form a 3D framework. Polyoxometalates (POMs) are a rapidly growing class of metal oxo clusters with a wide range...

An Investigation on Nanoscale-shape-mediated Coupling Between Temperature and Densification in Intense Pulsed Light Sintering of Silver Nanoparticles

Creator:: Bansal, Shalu
Abstract:: In Intense Pulsed Light (IPL) sintering, pulsed large-area visible light from a xenon lamp is absorbed by nanoparticle films or patterns and converted to heat, resulting in rapid sintering of the nanoparticles. This work experimentally characterizes IPL sintering of silver nanoparticle films. A newly observed turning point in the evolution...

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...

Plasma-Jet Printing and In Situ Sintering of Electronic Materials for Flexible Hybrid Electronic Applications

Creator:: Manzi, Jacob
Abstract:: Additive manufacturing has become a promising method for the fabrication of inexpensive, green, flexible sensors and electronics. Printed electronics on low- temperature substrates are very appealing for the flexible hybrid electronics market for their use in disposable and biocompatible electronic applications and in areas like packaging, wearables, and consumer electronics....
