Quantification And Characterization Of Aluminum Distributions In Commercial Beta And Mordenite Zeolites By Cobalt Exchange, Rebecca L. Reitzel, Claire T. Nimlos, Rajamani Gounder
Quantification And Characterization Of Aluminum Distributions In Commercial Beta And Mordenite Zeolites By Cobalt Exchange, Rebecca L. Reitzel, Claire T. Nimlos, Rajamani Gounder
The Summer Undergraduate Research Fellowship (SURF) Symposium
The aluminum distribution throughout the zeolite framework determines the structural, ion-exchange and catalytic properties of the zeolite. Several methods have been proposed to control the Al distribution, but in order to accurately assess these methods a procedure is needed to quantify Al distribution in various zeolite frameworks. Co2+ ions exchange onto the zeolite framework at Al pairs, and atomic absorbance spectroscopy (AAS) can be used to quantify the number of exchanged Co2+ ions and, in turn, the overall number of Al pairs. Each framework exhibits differences in pore size and channel configuration which affect the equilibrium conditions needed …

Effect Of Conveying And Distributive Mixing Elements On Breakage Phenomenon In Twin Screw Granulation, Jiayu Li, Shankali U Pradhan, Carl Wassgren
The Summer Undergraduate Research Fellowship (SURF) Symposium
Twin screw wet granulation (TSG) is gaining more attention and becoming an important process in the pharmaceutical industry. The process is widely implemented because of its flexibility, short residence time, and small equipment footprint. Past studies have shown that screw elements can have a significant impact on the performance of the TSG process. In addition, these studies identified that breakage of wet mass is a significant step in the process. Currently there is no literature that focuses on the effect of each screw element on the breakage process. In this work, experiments have been designed to isolate the breakage process …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Lewis acidic zeolites such as Sn-Beta are commonly studied for use as selective catalysts for glucose isomerization to fructose in liquid water. Glucose to fructose isomerization is a critical reaction for lignocellulosic biomass upgrading, which converts abundant and renewable feedstocks into commercially desirable fuels and chemicals.
Industrial applications require catalysts that maintain optimal reactivity over long time scales, yet at typical reaction temperatures, Lewis acidic Beta zeolites are known to deactivate in liquid water through poorly understood mechanisms. Recent work in our group has shown that interactions between water and Sn-Beta zeolites can cause leaching of active Sn sites from …

Continuous Ligand-Assisted Elution Chromatography Applied To Separation Of Rare Earth Elements, Jeremy A. Weinstock, David M. Harvey, N.-H. Linda Wang
The Summer Undergraduate Research Fellowship (SURF) Symposium
Rare earth elements (REEs) are metals used to make many valuable products such as magnets and electronics. Following their extraction from larger materials, REEs are to be separated into their individual components as high purity is required for product manufacture. Purification is very difficult because most (15/17) of the REEs are lanthanides (Ln’s) and Ln ions have the same valence and similar atomic radii. The current industrial process for purifying REEs involves using toxic solvents to perform a series of liquid-liquid extractions. Ling and Wang (2015) proposed a ligand-assisted batch chromatography process to purify Ln’s. The latter approach is a …

Exploring The Effects Of Aromatic Molecules In Chemical Enhanced Oil Recovery, Jacob M. Crain, Cliff Johnston, Rituraj Borgohain
The Summer Undergraduate Research Fellowship (SURF) Symposium
Chemical enhanced oil recovery (cEOR) methods are being used as a viable contributor to the world’s growing energy demands. Due to the complex chemical composition of crude oil, attempting to optimize the surfactant concentration and salinity of formulations is done empirically. This process can be very time intensive due to the wide variety of surfactant structures available for cEOR. Surfactant selection is typically done by matching the average chain length of the oil with that of the surfactant. In this study, we are trying to understand how aromatic structures present in Illinois Basin crude oil interact with surfactants. This will …

Amine-Thiol Solution Route Method For Fabricating Cdxzn1-Xs Thin Film Solar Cells, Preston D. Fernandez, Xianyi Hu, Carol Handwerker, Rakesh Agrawal
The Summer Undergraduate Research Fellowship (SURF) Symposium
Cadmium zinc sulfide, CdZnS, is a promising material for the buffer layer of thin film solar cells because the alloy is considerably more cost effective and more optimizable than pure cadmium sulfide, CdS, in terms of band gap. The current fabrication methods of the buffer layer often require expensive equipment or produce undesirable impurities in the alloy. This study investigates a cost effective and scalable solution route method to synthesize the CdZnS buffer layer. Molecular precursors of CdZnS were dissolved in varying molecular ratios of cadmium and zinc in a mixture of hexylamine and propanethiol. The resulting alloys produced were …

The Summer Undergraduate Research Fellowship (SURF) Symposium
The Food and Drug Administration (FDA) released in 2013 a report that established the pharmaceuticals current good manufacturing practices for the 21st century. This report encourages the creation of new technology in the pharmaceutical industry. Therefore, this research aims to develop a reliable method to produce porous polymers particles to be used in a novel continuous crystallization in porous substrate. The aim of the current work is to create porous polymer microspheres with uniform particle size distribution using a commercially available membrane emulsification system. In the present study, the emulsification was made using a dispersed phase composed of miglyol …

The Summer Undergraduate Research Fellowship (SURF) Symposium
More active, selective and stable catalysts are in demand to increase the yields of olefins production from light alkane dehydrogenation. Cu was reported to promote Pt catalysts and Pt-Cu catalysts has been shown to achieve increased olefin selectivity and decreased deactivation rate. Pt-Cu catalysts with different Pt:Cu molar ratios may have different crystal structure and performance. This study seeks to understand of the promotion effect of Cu on Pt alkane dehydrogenation catalysts. Four different Pt-Cu catalysts with different atomic ratios were prepared and tested for propane dehydrogenation at 550℃. Synchrotron in situ X-ray diffraction and X-ray absorption spectroscopy are used …

EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Laser ablation synthesis in solution in tandem with galvanic replacement reaction (LASiS-GRR) is a newly-developed, facile and environmental friendly synthesis technique for manufacturing a variety of complex nanostructures including hydroxides, metal/metal oxides nanocomposites (NCs), metal-metal nanoalloys (NAs), core-shell nanostructures, etc. This synthetic technique incorporates both “top-down” pulsed laser ablation synthesis in solution approach (LASiS) and the “bottom-up” chemical reduction method (CRM). The setup houses a Q-switched Nd:YAG pulsed laser (1064 nm) with the laser beam focused at a metal target in liquid medium inside a sealed stainless steel reactor cell. The cell is mounted with a gas inlet/outlet, viewing windows, …
