The research project involves designing and building circuits for a pulsed laser and photodetector for a speed of light time of flight measurement device and developing pedagogy and curricula for 200-level experimental laboratory and 400-level senior research project physics courses. We completed project-based learning on circuit principles, Kirchhoff’s Laws, RLC circuits, Thevenin and Norton equivalence, AC signal, phasors, RC filters, oscillators, impedance, diodes, transformers, operational amplifiers, metal–oxide–semiconductor field-effect transistors (MOSFET), and introductory optics and optoelectronics. We performed hands-on training on analog circuits logic and components, CAD design, prototyping, and practical physics applications of analog circuits. Technical lab responsibilities include learning to design analog circuits using a CAD program; ordering the printed circuit board (PCB); testing circuits for functionality, accuracy, and precision; testing the speed of light measurement device for precision with light passing through air and other mediums; and measuring the refractive index of different mediums. Physics education responsibilities include incorporating our work into BPHYS 231 Experimental Physics Speed of Light Lab; developing a pre-lab quiz and lab manual; and providing documented guidance for students on learning objectives, instructions on use of the new speed of light device, lab extensions for BPHYS 231 final projects, and research topics for BPHYS 433 Senior Project. Due to the large scope of this project, the research will continue through Autumn 2025.

The synthesis and characterization of films for interaction with methane and hydrogen is a project with two motivations. 1) TiO2 as a catalyst support has been found to favorably impact the activity in water gas shift reaction, a step carried out alongside Steam Methane Reformation (SMR) in the conversion of methane to hydrogen. We aim to understand the interaction between methane and TiO2 catalyst support deposited on an alumina substrate. A thermal evaporator was used to deposit titanium thin film onto alumina substrates and post oxidized in flowing oxygen at elevated temperatures (200-250°C). We observed evidence for the post-oxidized film to behave like a dielectric and acquire a charge when placed in the path of an electron beam in a Scanning Electron Microscope (SEM). 2) Depositing titanium onto graphite substrate to examine if there is enhancement in hydrogen incorporation into graphite due to Hydrogen Spillover Effect (HSPE).
