Data reduction and data visualization Python codes created with JupyerLab or Spyder for a comparative study on the mechanical properties of Titan's organic haze analogs. Programs regarding plots display the preliminary results of Young's modulus and hardness values of Titan haze analog simulation samples, or tholins, from NASA Ames Research Center (NASA ARC) and Johns Hopkins University (JHU), and are compared to literature values. These are nanoindentation measurements, and are shown for different nitrogen-methane gas mixing ratios. The Salt/Glycine codes are programs plotting the Young's modulus and hardness values of Salt/Glycine samples made at different concentrations and dried by either a hot plate or overnight in an oven. Ultimately, the mechanical properties of tholins can help us infer the transportation capabilities and origins of the dunes observed in the equatorial regions of Titan.
5% NASA ARC PLA Glass - 10%-40% FT.ipynb is the currently standardized formula of how raw nanoindentation data is reduced to obtain the overall Young's modulus and hardness for our tholin samples. This same methodology is used for all sample data reductions. E PLA Glass.ipynb and H PLA Glass.ipynb are an overview of current results on the mechanical properties for plasma tholins on glass substrates with Matplotlib visualizations. E PLA Glass Plotly ARC.ipynb and H PLA Glass Plotly ARC.ipynb display new NASA ARC nanoindentation results with an implemented correction of precise film thicknesses that are visualized using the Plotly package. Future will consists of measuring the film thicknesses of the JHU plasma samples with the M-2000 Spectroscopic Ellipsometer and applying those maps to nanoindentation data. These new corrections will soon be updated in the aforementioned notebooks.
Plots titled '1:6:2024' were implemented in my 2025 Lunar and Planetary Science Conference abstract submission: A Cross-Laboratory Comparison of Titan Haze Analogs: Mechanical Properties. They display the preliminary results for the Young's modulus (GPa) and hardness (GPa) 5% CH4/N2 NASA ARC and JHU plasma tholins and are compared to Yu et al. (2018, 2017). The substrates of each sample is also included for comparison and efforts to answer the question of substrate choice influencing the mechanical properties of tholins.
