Running Shoe Pedometer, Benjamin Kasper
Running Shoe Pedometer, Benjamin Kasper
Williams Honors College, Honors Research Projects
Running shoe pedometer aims to solve the issue of worn out running shoes. It can be difficult to know just how many miles you have run in your shoes and when a new pair is needed. Running in old shoes and worn out shoes is heavily linked to injury. My proposed project is a device that is powered by the compressive forces on the shoes soles that counts the number of steps the wearer takes using a microcontroller. Then, when the shoe reaches milestone that indicate it has been used 75% 90% and 100% of its expected life, it will …

Level And Temperature Controlled Vessel, Cameron Macesich
Williams Honors College, Honors Research Projects
Using two Arduino microcontrollers, level and temperature Proportional-Integral control systems for a continuously stirred tank reactor were designed and configured. Open-loop step tests were performed and fitted with First Order Plus Time Delay responses so that controller tuning parameters could be analytically derived. The effectiveness of the designed systems was evaluated by monitoring the response of closed-loop setpoint changes.
Scale-Up Of Flow-Electrode Capacitive Deionization Method For Hard Water Softening, Noah Henry
Scale-Up Of Flow-Electrode Capacitive Deionization Method For Hard Water Softening, Noah Henry
Williams Honors College, Honors Research Projects
This study’s purpose is to further document a capacitive deionization design that could be capable of purifying H2O at a household scale where clean water is otherwise unobtainable in applicable regions of the world. The hypothesis behind this study was continuously larger scaled electrochemical cell-units would increase their water softening capabilities in sustainable fashion. The trend at which performance will scale is currently unknown. The units studied were constructed using graphite plates, anion exchange membranes, cation exchange membranes, and Teflon channels. Three streams, two being CaCl2 solutions in DI H2O (one being concentrated with CaCl …
Cold Plasma Enhanced Active Sites On Supported Nip Nanoparticles For The Oxygen Evolution Reaction, Michael Ricci
Cold Plasma Enhanced Active Sites On Supported Nip Nanoparticles For The Oxygen Evolution Reaction, Michael Ricci
Williams Honors College, Honors Research Projects
Identifying materials to efficiently facilitate the oxygen evolution reaction (OER) is key to advancing water electrolysis, an essential technology in the pathway towards a sustainable energy future. Here, we explore cold-plasma treatment as a facile method to enhance the activity of NiP nanoparticles supported on activated carbon. NiP nanoparticles were synthesized on an activated carbon support using a solid-state method and were then treated with argon, oxygen, and hydrogen plasmas for extended times. In all cases, plasma treatment reduced the number of active sites on the support. OER activity was evaluated by testing the materials in alkaline conditions. The activities …
Improving The Delivered Specific Impulse Of Composite Rocket Propellant Through Alteration Of Chemical Composition: Methodology And Parameters For Characterization Of Propellant And Validation Of Simulation Software Common To The Amateur Rocketry Community, Isaac O'Brien, Austin Ryan
Williams Honors College, Honors Research Projects
In this study, two solid composite rocket propellants were designed utilizing ProPEP, a rocket propellant formulation software common in the amateur and hobby rocketry communities. The two propellants were designed to optimize specific impulse relative to a literature propellant designed by 1020 Research Labs. The literature propellant was also tested in order to validate the design of experiment as well as the mixing and testing procedures. All three propellants, which includes the literature propellant RCS-P, and the two novel propellants AKR-P1 and AKR-P2 were characterized with static tests. The results of the static tests provide data on propellant performance and …
Compression Set Improvement Of Thermoplastic Vulcanizates For High Temperature Tubing, Mitchell Valaitis
Compression Set Improvement Of Thermoplastic Vulcanizates For High Temperature Tubing, Mitchell Valaitis
Williams Honors College, Honors Research Projects
It was hypothesized that increasing the curative level of the fluorocarbon rubber (FKM) used in manufacturing of thermoplastic vulcanizate (TPV) materials would decrease the compression set values of the TPV enough for it to be suitable as a flexible, lightweight alternative to high operating temperature thermoset rubber tubing currently being used for power steering hose. First, promising TPV formulations were identified by varying the polyamide (PA) and FKM used in a Brabender mixer. Four different types of polyamide and four different types of FKM were investigated, with two of the FKM types and one polyamide type identified as being promising. …
Reaction Kinetics Of The Hydrogenation Of Phenol In A Tubular Reactor, Michael Selzer
Reaction Kinetics Of The Hydrogenation Of Phenol In A Tubular Reactor, Michael Selzer
Williams Honors College, Honors Research Projects
The reaction kinetic parameters for the hydrogenation of phenol to cyclohexanone are determined for the liquid phase reaction with the palladium catalyst supported on an electrospun PVDF membrane. Runs of the reactor were completed at catalyst loadings of 40, 50, and 60 g/m2, and tube diameters of 0.187 in and 0.25 in with a runtime of ten hours. One-dimensional and two-dimensional models of the experimental setup were developed. Fitting data to the one-dimensional model found that the pre-exponential factor was 2.50 x 104, the activation energy was 7.69 kJ/mol, and the order with respect to phenol …
Platinum-Rhodium Alloy Electrocatalyst Activities In The Methanol Oxidation Reaction, William R. Sandorf
Platinum-Rhodium Alloy Electrocatalyst Activities In The Methanol Oxidation Reaction, William R. Sandorf
Williams Honors College, Honors Research Projects
This study evaluates the electrochemical activity of several compositions of platinum-rhodium alloys on carbon support to identify potential replacements for the expensive platinum electrocatalysts currently used in direct methanol fuel cells (DMFCs). The electrochemical active surface areas (ECSAs) of each sample were determined using cyclic voltammetry (CV) in a 0.5 M H2SO4 solution to normalize CV currents generated in the methanol oxidation reaction (MOR). The activity of five compositions was tested; Pt3Rh, Pt2Rh, PtRh, Pt2Rh, and Pt3Rh. 100 mg of each catalyst was synthesized at 10% by weight platinum …
Selective, Catalytic Decomposition Of Hydrazine, Benjamin A. Kitson, Shirin N. Oliaee
Selective, Catalytic Decomposition Of Hydrazine, Benjamin A. Kitson, Shirin N. Oliaee
Williams Honors College, Honors Research Projects
The selective, catalytic decomposition of hydrazine has been investigated using a 1 wt% Pt-Ni(OH)2 catalyst system quantitatively studied by changing the following parameters; reaction solution alkalinity, temperature, hydrazine concentration, catalyst selectivity, catalyst stability, and catalyst durability. Using sodium hydroxide (NaOH), the best alkalinity was found to be 1 M NaOH. The optimal temperature was found to be 50 °C for complete hydrazine conversion. A hydrazine concentration of 0.1 M produced the most effective reaction. The catalyst was found to be completely selective in hydrogen and nitrogen production with no ammonia formation. The catalyst activity decreased by 15% after 8 …
