In recent years, non-renewable and non-biodegradable plastic packaging forms the majority of landfilled waste. These products, mainly made from Polyethylene Tetraphlatate (PET) and other polyolefins, have excellent durability and barrier properties, but take hundreds of years to degrade.
Much focus has been put on developing environmentally friendly alternatives to polyolefins...
The electrical conductivity data of ceramic material at high temperatures can be useful in the application of modeling, solid oxide fuel cell (SOFC), and magnetohydrodynamic (MHD). The existing data is considerably lacking at extreme temperatures. Our research focuses on bridging this gap by reporting the electrical conductivity measurements of sets...
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,...
The cost of long-duration energy storage poses one of the most significant limitations on the penetration of renewables into power grids. Thermochemical energy storage has great potential to reduce this cost through the use of a reversible redox reaction pair that has a high enthalpy of reaction. The chemical nature...
Determining the electrical properties of ceria-based materials is important for their use as electrodes in hot-wall magnetohydrodynamic (MHD) power generators with wall temperatures greater than 1500 ̊C. The electrical conductivity of a material can be used in models for predicting the performance of generator designs. More specifically, the temperature dependent...
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...
Resilient interdependent critical infrastructures (CIs) can better withstand cascading failures in disruptive events. This study proposes network expansion as a resilience improvement strategy for interdependent CIs and evaluates the influence of topology in interdependent network design for resilience optimization under disruption uncertainty. A resilience score consisting of network complexity and...
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...
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....
This thesis presents a novel design for a rheometer style viscometer by implementing high temperature and inert atmospheric requirements on the device. The goals of this device are to measure the viscosity of high temperature molten salts, which are corrosive and extremely hydroscopic. It also aims to be able to...
