2018 Celebration Of Scholarship, Creativity And Engagement, Eastern Illinois University

Programs

Scholarship, creativity, innovation, and the many forms of collaborative engagement that shape faculty life and student learning are central to the mission of Eastern Illinois University. For that reason, our faculty, department chairs, college deans, the provost, and the entire campus community celebrate the achievements and outstanding contributions of our colleagues and students to their disciplines and professions every year.

And, as the following pages illustrate, faculty engaged in continuing scholarly and creative activities provide outstanding mentoring experiences for our undergraduate and graduate students.

In addition to recognizing faculty performances, shows, publications, grants and other professional efforts, the University will …

Co-Product Potential Of Algae Biocake, Elizabeth J. Nixon

Masters Theses

Society needs to find replacements for fossil fuels, which are finite resources that may be fully depleted within a few generations. While solar and wind have great potential as alternative energy sources, they are unlikely to completely replace all of the current fuel sources, particularly liquid fuels. Plant biomass has great potential for this market, and is already used in many forms for heat energy (e.g. direct combustion). However, the bulk density of important bioenergy crops, particularly grasses, is often low, which necessitates the use of binders in densification strategies. In the present study, waste algae biocake from a proprietary …

Synthesis And Characterization Of Biomimetic Dinuclear And Tetranuclear Copper Complexes, Syed Rahmath Ullah Joy

Masters Theses

Seven new copper(II) complexes were prepared from the condensation reaction of 4-tert-butyl-2,6-diformylphenol with two equivalents of bis(pyrazolyl)ethanamine or 3,5-dimethyl-bis(pyrazolyl)ethanamine moieties in the presence of two equivalents of various copper(II) starting materials having different counter ions (i.e. acetate - AcO^-, perchlorate - CIO₄^-, tetrafluoroborate - BF₄^-, nitrate - NO₃^-, and chloride - Cl^-). The resulting copper(II) complexes were characterized in solid state by single crystal X-ray crystallography, and in solution by UV-Vis and ESI/MS spectroscopies.

X-ray crystallographic studies showed that in solid state two types of …

Pd-Based Photocatalysts For Sonogashira C-C Cross-Coupling Reactions, Komadhie Charuka Dissanayake

Masters Theses

Sonogashira C-C cross-coupling reaction has been heavily used for its simplicity, flexibility and value. Although the original Sonogashira C-C cross coupling reaction conditions entail the use of 0.5 mol% of Pd catalyst, 2 mol% of Cul as co-catalyst at room temperature, the experimental conditions used in laboratories to prepare some compounds vary substantially, especially with respect to the reaction time, temperature and loading amount of the catalysts. The most significant drawback of the conventional Sonogashira reaction is the use of Cul as it leads to the formation of homocoupling product when the reaction is exposed to air or oxidizing agents. …

Impact Of Temperature Increase On Freshwater Fish Species: Energetics And Muscle Mechanics Of Two Centrarchids, Israt Jahan

Masters Theses

Fishes have evolved physiologically to live within a specific range of environmental variation and existence outside of that range can be stressful or fatal. These ranges can coincide for fishes that evolved in similar habitats. This study investigates physiological processes limiting thermal tolerance, specifically how changes in water temperature affect the swimming energetics and muscle mechanics in largemouth bass (Micropterus salmoides) and bluegill (Lepomis macrochirus). I focused on the impact of temperature change at the muscle level in these two species and the capacity to adapt to rapid changes in the environment. Fish were housed at …

Defense In Depth Network Perimeter Security, Anuoluwapo Ope Fatokun

Masters Theses

Defense in depth network perimeter security has always be a topic of discussion for a long time as an efficient way of mitigating cyber-attacks. While there are no 100% mitigating method against cyber-attacks, a layered defense in depth network perimeter security can be used to mitigate against cyber-attacks. Research have shown a massive growth in cyber-crimes and there are limited number of cyber security expert to counter this attacks. EIU as an institution is taking up the responsibility of producing cyber security graduates with the new Master of Science in Cyber Security program that started in Fall 2017.

This research …

Processing Different Mixtures Of Regionally Available Resources To Create Pellets That Meet A Minimum Standard, Jacob Hixson

Masters Theses

There are several ways to produce energy today, one of the oldest is the gasification of biomass. This process uses a fire to heat the material until it starts to produce gasses that are used as fuel. There are several types of biomass that can be used, many of which have large pieces with low bulk densities. By pelletizing the biomass bulk density increases and allows the opportunity to add in other biomass materials.

There are standards for condensing large pieces of biomass to smaller pelletized materials. Pellet Fuels Institute has set minimum standards for pellets used in the different …
