Williams Honors College, Honors Research Projects

This work investigates the use of two different polyols, xylitol (Xyl) and erythritol (Ery), in conjunction with boron nitride (BN) aerogels, for the purpose of creating thermally conductive composites. While the BN filler in Xyl composites achieved a high anisotropic thermal conductivity of up to 4.53 W/m-K at 18.2 weight percent filler loading, they do not exhibit good phase-change material qualities due to a low solidification enthalpy even at low cooling rates. Alternatively, the BN-Ery composites have shown promising results with a solidification enthalpy of 225.14 J/g and a melting enthalpy of 385.84 J/g at a heat rate of 5 …

Dynamic Voltage Rail Audio Amplifier, Evan Von Duhn, Timothy Oshatiouk, Slavisa Tosanovic, Andrew Cantrell

Williams Honors College, Honors Research Projects

The goal of this project is to create a high-quality, power-efficient audio amplifier. Most modern audio amplifiers use a constant amount of power regardless of the signal that is being amplified. This means that both loud and quiet portions of the audio signal require the same amount of power to amplify. The idea for this high-quality, power-efficient audio amplifier is that the quieter portions of the audio signal can be amplified using less power. This will be achieved by first analyzing the audio signal and controlling the power source based on the signal’s needs. Therefore, louder parts of the audio …

Optimization Of Conditions For Production Of Mechanically Strong Suckerin Protein Hydrogels, Autumn Furniss

Williams Honors College, Honors Research Projects

Hydrogels are polymer networks with a large water content. Uses include biomedical applications like drug delivery, wound dressing, and more. Current natural hydrogels lack mechanical robustness. Squid ringed teeth (completely protein) have a modulus comparable to thermoplastics; adding this to hydrogels could improve modulus while maintaining biocompatibility.

Three experiments were performed: Hofmeister solubility study, SRT powder additive, and SRT aqueous solution. The first showed that LiCl solution without acetic acid dissolved the most SRT; overall LiCl dissolved more than all others. SRT as a powder additive increased the modulus of the hydrogels, however the error in the measurements make it …

Effects Of Hofmeister Ions On Transition Temperature Of Two Thermo-Responsive Polymers, Joshua Moser

Williams Honors College, Honors Research Projects

It was hypothesized that through the use of Hofmeister Ions, the lower critical solution temperature (LCST) of poly(vinyl methyl ether) (PVME) and poly(ethylene glycol)- poly(N-isopropylacrylamide) (PEG-b-pNIPAAm) block-copolymer could be controlled. Through literature searches and small lab experiments, our team found that there may be a connection between Hofmeister effects and phase transition of a thermo-responsive polymer. To try and prove this, the lab team decided to take four cations (Mg²⁺,Na⁺, Cs⁺, K⁺) in solution with the thermo-responsive polymers and compared their LCST to solutions of the thermo-responsive polymer in de-ionized …

Artificial Intelligence Of Stormwater Operations, Eric Bednar

Williams Honors College, Honors Research Projects

The current infrastructure in our country will not be able to adequately support the growing demands of an exponentially increasing population. A rise in population contributes to a greater service demand necessary to treat sanitary sewer waste which in many cases contributes to the flow of combined sewers. When it comes to managing these combined sewers, rain and the snowmelt caused from climate changes are major factors that need to be addressed. Some water treatment facilities do not have the ability to treat the capacities or peak flows that a system experiences, resulting in combined sewer overflows which are both …

The laser ablation of metal carries relevance in a variety of engineering industries. This includes, but is not limited to, processes such as micromachining, or implementation on aircraft weaponry. The latter application is the reasoning for why aluminum is the specific metal in consideration, as it is commonly used for the construction of aircraft components.

The scope of this project was to optimize the energy dispersed through laser ablation on aluminum by mathematical modeling. The transient conduction process in the aluminum was modeled using a 2-dimensional cylindrical coordinate system in both MATLAB and ANSYS/Fluent. These models were adopted to simulate …

Artificial Intelligence In Wastewater Treatment Facilities: Implementing Practical New Technologies For The End User, Jordan Spano

Williams Honors College, Honors Research Projects

Design phase operator input can prove useful; however, it is not essential in every application, as Akron’s treatment plant implemented AI to increase treatment capacity without design-phase operator input. They implemented a system flight simulator, a few hours training, and have communicated with the designer to make system tweaks as needed. In larger applications, the owner may benefit greatly by incorporating design input from operational staff. Those representing a municipality as a project owner for a treatment plant upgrade should always maintain an active role in the design of smart water infrastructure. They must keep the operators in mind when …
