- » Lochinvar Gas Fired Heaters I: Flue Gas Recirculation for NOx Reduction
Team Members: James (Cameron) McLaughlin, Kenan (Keni) Colakovic, Nathan Stewart
Mentor: Ben Putnam, Lochinvar
Project Overview: Combustion-based water heaters have a universal problem of producing harmful emissions that are a threat to the Earth’s atmosphere. Lochinvar is a company based out of Lebanon TN, and they produce combustion-based water heaters. Government regulations have become much stricter over the years about NOx emissions, and this has put pressure on the company to find a quick solution to this issue. In this project proposal, a method will be presented to reduce these emissions and provide Lochinvar with a solution to the problem.

- » Rum Quality I: Extrinsic Oxidation
Team Members: Emily Yates, Aaron Davis, Austin Brewington
Mentor: Phil Pritchard, Pritchard Distillery
Project Overview: Prichard’s Distillery produces a cranberry flavored rum that initially exhibits a bright red color derived from cranberry concentrate. However, after approximately five to six months of storage, the product gradually shifts to an amber-brown color and then a pale-brown color after more time. During a visit to the distillery, it was also observed that the flavor profile changes as the product ages. The fresh cranberry rum produces a strong cranberry taste when first consumed and leaves a tarte cranberry aftertaste. In contrast, the degraded samples taste primarily like straight liquor with only a faint cranberry aftertaste. These observations suggest that chemical degradation of the cranberry compounds occurs during storage.
This project will investigate oxygen ingress through bottle closures as a potential contributor to both color and flavor degradation. The current bottling process does not include inert gas purging prior to the cork insertion, meaning atmospheric oxygen remains in the bottle headspace when sealing. Additional oxygen may also diffuse into the bottle over time through the cork material or at the cork-glass interface. This project will evaluate natural and synthetic cork closure, as well as secondary sealing methods including shrink wrapping and wax dipping, to determine their relative effectiveness at limiting oxygen ingress during storage. In addition to cranberry rum samples, bottles containing a methylene blue indicator solution will be used as a parallel oxygen-sensitive system, allowing visual tracking of oxygen ingress independent of the rum’s complex chemistry. The study was split into three primary sections by the research teams:
· Polymerization and pH
· Intrinsic Oxidation
· Extrinsic Oxidation (The focus for this team) - » Rum Quality II: Intrinsic Oxidation
Team Members: Thomas (Gray) McMurty, Parker Rosenblatt, Noah Oaks
Mentor: Phil Pritchard, Pritchard Distillery
Project Overview: The purpose of this capstone project is to find and fix the problem behind the color degradation in Prichard’s Cranberry Rum. The bright red color of this rum is going away over time, and the problem we think it is facing is intrinsic oxidation of the anthocyanin compounds. Throughout the course of this project, tests based on dissolved oxygen, heat exposure, and UV visibility will be run to prove the issue of oxidation. Gallic acid was researched to be a possible solution to an oxidation problem, so trials implementing this chemical will be run after oxidation tests. The study was split into three primary sections by the research teams:
· Polymerization and pH
· Intrinsic Oxidation (The focus for this team)
· Extrinsic Oxidation - » Rum Quality III: pH/Polymerization
Team Members: Daniel Kidder, Wyatt Tunstall, Stephen Combs, Philopateer (Phillip) Fakhry
Mentor: Phil Pritchard, Pritchard Distillery
Project Overview: Color stability is crucial in fruit based alcoholic beverages, and it influences the customer's perception and the acceptance of the product itself. The reason cranberry based beverages have their deep dark red hue is due to Anthocyanins, which are type of plant pigment. Many fruits and vegetables receive their red, purple, and blue hues from these molecules, which are members of the anthocyanin family of polyphenolic compounds. A rum manufacturer discovered that their cranberry rum is having a color change and degrading over time. The beverage that looked rich and deep red gradually changed to brown or yellow with some taste changes. Depending on the pH of the solution, anthocyanins can take on a variety of structural shapes. The equilibrium between these forms is shifted by pH changes, resulting in a variety of hues, from red in acidic environments to blue or colorless at higher pH levels. (Mazza & Miniati, 1993). Anthocyanins are very sensitive to a few environmental elements such as temperature, pH, oxygen exposure, and chemical interactions. That leads to anthocyanin containing beverages having a gradual color change over time in storage. Anthocyanins are merged into an alcoholic structure together with sugar, ethanol, water, and other organic molecules when cranberry juice is added to the cranberry rum product. Color is important for marketing and the quality of the product. Comprehending the chemical mechanism responsible for the degradation is crucial. The capstone project teams were tasked to figure out the cause and of the color change and how to fix it. The study was split into three primary sections by the research teams:
· Polymerization and pH (The focus for this team)
· Intrinsic Oxidation
· Extrinsic Oxidation - » Unit Operations Equipment I: Absorption/Stripping
Team Members: Ryan Martin, Zachary Wright, Katherine Delk
Project Overview: The Absorption and Stripping columns in Tennessee Tech’s Unit Operations Lab are used by students to understand mass transfer principles such as countercurrent gas-liquid flow and the concept of gas scrubbing. However, these columns are in need of maintenance and upgrading. The columns are dirty, have several broken parts, and are lacking the proper components to be run experimentally for students.
To address these issues, the project has been divided into three main sections: cleaning, component replacing, and CO2 integration. For the first several weeks, the apparatus will be cleaned; this will include flushing out rust, cleaning or replacing the packing, disassembling shower heads, and attending to other issues that arise during the cleaning process. After that, component replacing will begin. Two flowmeters—the air flow meter and liquid flow meter—will be removed from the system and replaced with new ones. Additionally, other pipes and fittings will be replaced. Finally, once the system is up to date, a CO2 tank will be connected, and experiments will be run to ensure that it works as intended. By the end of this project, the columns will be useable by future students in order to understand important concepts in chemical engineering.
- » Unit Operations Equipment II: Liquid/Liquid Extraction
Team Members: Brandon Levan, Jalen Lajas, Ian Johnson
Project Overview: Liquid–liquid extraction is an important separation process in chemical engineering, but the department’s Hampden Model H-6150 extraction trainer has not been used in over ten years. Because of that, it currently is not available for lab instruction and needs to be inspected, tested, and brought back into working condition before it can be used again.
The goal of this project is to get the extraction unit fully operational and confirm that it runs safely and consistently. This includes checking the mechanical components, verifying the flow paths, calibrating the instrumentation, and running controlled startup and shutdown procedures to make sure everything functions as intended. We will also document clear operating procedures so future students can use the system without confusion. By the end of this project, the extraction trainer should be fully functional and confirmed for lab use. Restoring this unit will bring back a valuable hands-on learning tool and give students the opportunity to work directly with real separation equipment instead of only learning the theory.
- » Unit Operations Equipment III: Distillation
Team Members: Joshua Galindez Echeverry, Nolan Holbrook, Robert (Tyler) Strader

The goal of this project is to restore the column to proper working conditions through maintenance, replacement of faulty components, and upgrades to its monitoring system. Key tasks include cleaning the steam traps to remove rust and calcium buildup, replacing broken thermocouples and their wiring, and installing a new computer system to run the LabVIEW software. The upgraded system will include a touchscreen display, a secondary monitor, and a camera to monitor the distillation trays during operation.
The project team will work collaboratively to complete maintenance, install upgrades, and test the system. Performance will be verified by collecting temperature data with the thermocouples and analyzing it to ensure the column operates correctly. Overall, the project will restore functionality to the distillation column and improve its monitoring capabilities, allowing it to continue serving as a reliable laboratory resource for future experiments.
- » Electrochemistry - Nitrate Reduction
Team Members: Nikolas Vassilev, Aspen Lynch, Rochelle Harmon, Morgan Patterson
Mentor: Dr. Ali Estab, Tennessee Tech University
Project Overview: The chemical reduction of nitrates in wastewater is currently costly and operationally complex when using conventional treatment methods. This project advances the use of electrochemical cells as an approach for nitrate reduction, with the goal of selectively converting nitrates into benign nitrogen gas to align with existing wastewater treatment infrastructure requirements. Laboratory experiments will be conducted in a controlled, closed system to ensure that gas products are captured. Reaction products will be analyzed to determine both conversion efficiency and ammonia content.
The study is designed with consideration for scalability, economic feasibility, and integration with current treatment systems. It is expected that nitrate reduction will exhibit selective behavior at specific applied potentials, producing nitrogen gas, ammonia, and other intermediate species depending on the operating conditions. Controlling and varying these conditions will help identify optimal operating parameters for minimizing ammonia production. Further research could explore alternative electrochemical cell configurations and catalyst materials. If successful, this approach could contribute to significant reductions in operational costs for wastewater treatment facilities while improving the efficiency of nitrate removal.
- » Lithium Salt Recyrstallization
Team Members: Hayden Wright, Logan Ballon, Michael McNabb, Enzo Fabris Rocco, Ethan Burt
Mentor: Dr. Bahman Ghorashi, Tennessee Tech University
Project Overview: Lithium is a critical resource for modern technologies, particularly for lithium-ion batteries used in energy storage and electric vehicles. While lithium is present in seawater and aqueous brines in the form of positive lithium ions, its concentration is relatively low and efficient extraction methods remain an important area of research. With the increasing use of desalination processes worldwide, large volumes of concentrated brine streams are produced that may represent a viable source for lithium recovery.
This project proposes a bench-scale method for lithium carbonate separation based on the opposing solubility behaviors of sodium chloride and lithium carbonate. Sodium chloride is more soluble at higher temperatures, whereas lithium carbonate exhibits decreased solubility as temperature increases. By exploiting this difference, a mixed aqueous solution containing sodium chloride and lithium carbonate will be heated to induce crystallization of lithium carbonate. The solution will then be slowly cooled to promote crystallization of sodium chloride, ideally producing separate solid precipitates of each compound. The experimental process will involve preparing aqueous solutions containing sodium chloride at concentrations representative of seawater or desalination brines, while lithium carbonate will be added until saturation is reached at slightly elevated temperatures. The solution will then be heated to promote lithium carbonate crystallization and subsequently cooled in a controlled manner to form sodium chloride crystals. The resulting solids will be isolated and washed, and their purity will be evaluated through acid–base titration using hydrochloric acid and sodium hydroxide.
The scope of this project includes process simulation, safety evaluation, and experimental error analysis. The primary metric of success will be the purity of the recovered lithium carbonate crystals, with a target purity of at least ninety percent, just shy of lab-grade. Achieving high-purity lithium carbonate would demonstrate the feasibility of this thermally driven separation approach. By demonstrating lithium carbonate recovery from saline solutions at the bench scale, this project aims to provide proof of concept for a scalable separation process. If successful, the approach could contribute to future industrial methods for recovering lithium from seawater or desalination brines, supporting the growing demand for lithium resources.
- » Bio Processing I: Optimization of Fibrin Gel Formation using varying Thrombin and
Fibrinogen Concentrations
Team Members: Lilian Sissom, Hannah Farill, Kenzie Fowler, Aaron Livesay, David Giraldo
Mentor: Dr. Robby Sanders, Tennessee Tech University
Project Overview: During the wound healing process, fibrin is formed by the body as a result of the coagulation cascade to achieve homeostasis. The final state of an in vivo fibrin gel formation is executed by the on-site mixing of thrombin and fibrinogen. Although the Chemical Engineering Department at Tennessee Technological University seeks to research the ex vivo formation of fibrin gels, much of this work has been halted due to faulty results revolving around either the gel formation or drying processes. This formal project proposal will highlight the plans for experimental methods, analyzation, and results conducted regarding the critical point drying process utilized for fibrin gel formation.
- » Bio Processing II: Critical Point Drying of Fibrin Gels
Team Members: Aiden Gillis, Lucille White, Chloe Foshie, Malcolm Sherbine
Mentor: Dr. Robby Sanders, Tennessee Tech University
Project Overview: Fibrin gels are widely used biomaterials in biomedical engineering due to their biocompatibility and ability to form natural scaffolds for tissue regeneration and wound healing. Fibrin gels form when the enzyme thrombin cleaves fibrinogen, producing fibrin monomers that polymerize into a three-dimensional network. The physical properties of the resulting gel, including density, strength, and gelation time, depend strongly on the concentrations of thrombin and fibrinogen used during polymerization.
The goal of this project is to investigate how variations in thrombin and fibrinogen concentrations influence fibrin gel formation and polymerization kinetics. Solutions of fibrinogen and thrombin will be prepared at several concentrations and pipette-mixed to initiate fibrin polymerization. Immediately after mixing, the samples will be transferred to a spectrophotometer to measure turbidity changes over time. As fibrin fibers form, the solution becomes increasingly turbid. These absorbance values can be used in empirical equations to describe the gelation of the fibrin gels. The results will provide insight into how fibrin and thrombin concentrations affect fibrin network formation. Understanding these relationships is important for determining the optimal gel composition for the various applications of fibrin gel, such as tissue engineering, wound healing materials, and drug delivery systems.

This development enhances emergency response by providing critical health metrics and situational awareness in situations where time is of the essence.
Manufacturing and Engineering Technology
- » Delivery Drone
Team Members: Neal Harris, Karl Szumski, Jabari McClendon, Chantal Nizgiyimana
Project Overview: There is a growing demand for affordable drones that can transport small payloads for delivery, emergency response, and military support applications. Many existing drone systems are either too expensive or not flexible enough to be easily modified for specific payload needs. This project focuses on the design and construction of a cost-effective drone capable of carrying a small payload while maintaining reliable flight performance. The drone is designed to transport a payload between 2 and 2.5 pounds while keeping the total project around $1,000. Throughout the design process, the team prioritizes three main factors: cost, thrust, and overall functionality.
- » Baja Cart Lift
Team Members: Angelo Pisano, AJ Wild, Brooks Williams, Luke Huddleston, Owen McNeil, William Bell
Project Overview: The Tennessee Tech BAJA SAE and Formula SAE teams have a need to store their karts in a safe, efficient, and portable manner. The team's current storage consists of the AIEB building workshop and their old shop under the stadium. The stadium is being removed, and the AIEB shop is already tight on space. This makes the need for a more efficient storage system that offers the ability to move from the stadium shop to an interim position and then move to a permanent position within a future building that is not expected to have power. This project solves these problems by utilizing vertical space to condense storage while being portable to move between locations and operating without electricity. Being able to stack the karts two to three high offers flexibility in the interim storage location, condenses storage in the future building, and keeps the karts safely accessible without outside material handling equipment.
- » Pressure Sensitive Brake Light
Team Members: Shiloh Caudill, Isis Decker, Landon Symes, Colton Beverly, Nathan Penuel, Kyra Sims
Project Overview: There is a need to know how hard drivers on the road are braking. In current braking system designs the indication of braking offers limited information to the other drivers. A three-tiered brake light would address this limitation by utilizing a system in which the intensity of the force used on the brake pedal correlates to varying levels of the brake light illumination on the rear of the vehicle. Although some manufacturers have begun implementing new concepts in hopes of addressing this issue, a widespread adoption of the three-tiered brake light would provide a clearer and more effective visual warning.
- » Adjustable Foundry Table
Team Members: Sterling Stephens, Micah Boyd, Colby Davis, Emma Waller, Reuben Smith, Thomas Haskell
Project Overview: Working in the Tennessee Tech University Foundry requires a certain amount of physical strength. Technicians and students should be able to lift a full ladle of molten metal, carry a packed mold to the pouring line, and then to the shake-out station. This puts a restriction on some people who can be in the foundry, which is not the desired outcome. To counteract this predicament, a mobile lift table will allow students to move their molds to the pouring line with more ease without the needed degree of physical strength.
- » (LiDAR) Based Proximity Alert for Bicycle Helmet
Team Members: Stephen DeWees, Daniel Gregory, Michael Mardis
Project Overview: Distracted driving has been a problem on the roads for many years, whether you’re reaching down to put in a different cassette, or changing the song on your smart phone. This creates a uniquely dangerous situation for cyclists that travel on the same roads as automobiles. As cyclists tend to be within lanes of traffic similar to drivers, many can find themselves at risk of being unseen. This has become a much larger problem in the last 15 years with the invention and popularization of smart phones. In this project, the problem of cyclists being endangered by distracted drivers is partially remedied by having a similar effect to automobile brake lights, alerting motorists of the cyclist's presence during darker conditions, and flashing at the motorist if they are approaching too quickly.
- » Gyroscopic Motorcycle Headlight
Team Members: Brett Jones, Hayden Wynne, Jacob Beaty, Grayson Hendrix, Jordan Timmons, Wyatt Oakley
Project Overview: There is a need for a gyroscopic motorcycle headlight assembly in most cases for modern day riders. Motorcycles are often not only turned with the handlebars, but also by leaning the rider’s body and the bike itself. In general, a motorcycle headlight assembly is fixed to the handlebars or to the chassis itself and does not move beyond the current steering angle of the forks, if at all. This steering angle is often less than the angle that the bike is actually turning. The solution to this is to create a mountable gyroscopic mechanism that allows the headlight to turn with the lean of the motorcycle.
- » Automated Sorting Machine for Paint Plugs and Stud Covers
Team Members: Abraam Shounod, Brennan Williams, Bryson Myers, Daniel Shelby, Wyatt Vance
Project Overview: Paint plugs and screw covers are a small but essential part of the production process on any blow molded parts that require paint. These fixtures seal off the interior of the part and encase any already attached screws so that they remain untouched during the painting process. This prevents any dust trapped inside the part from blowing out during painting and contaminating the painting room, as well as the buildup of paint on screws which can harm their effectiveness. Due to their importance, operators must constantly have a variety of plugs and covers on hand at all times, but their small size makes it hard to keep them organized. Often, they are simply thrown together in buckets that operators must sift through every time they need more. This wastes valuable time that operators could be using to create parts, and the tediousness of sorting is a source of frustration for operators. In this project, the problem of unorganized paint plugs and stud covers is addressed through the creation of an automated sorting machine that will separate plugs and covers into separate groups.
- » Mechanism for Loading and Flipping on Enamel Line
Team Members: Jacob Clark, Carson Guldan, Curtis Kilgore, Alex Parchem, Jon Simmons, Braxton Smith
Project Overview: Bradmark Industrial Coatings seeks to automate the loading and flipping of various sized metal and porcelain parts on one of their enamel coating lines. The current enameling line has four employees on it with two loading parts at the beginning of the line and two flipping parts on the line before the second coating booth. Previously, manpower was used in this process due to the complexity and cost of automation. However, by automating this process, Bradmark can reduce costs, streamline efficiency, and utilize employees in other more efficient ways.
- » PLC Automated Wire Cutter
Team Members: Abhi Patel, Dylan Evans, Zach Kortarba
Project Overview: The PLC automated wire cutter will help reduce the waste of excess materials. Cutting wires by hand has proven to be difficult and time-consuming, as people often struggle to cut the wire to the desired length and are required to cut the wire again to resize it or cut out a new wire with a greater length. This often results in the wasting of both time and materials, as multiple tries are needed to get the wire to the appropriate length.
