Objectives New Antimicrobial Testing Calculations for New Film Synthesis using JD-230, instead of JD-400 Make Agar plates use microwave, not oven Cure T-Plates for strength test To carry out thermodynamic tests To analyze XRD data obtained on 20/02 for epoxy and epoxy and TiO2 films Antimicrobial Testing The cells dried on the film so we decided to redo the testing from last Friday with 1400 micro-liter, instead of 600 micro-liter Place the petri dishes in a closed humid dark environment Check on the cells on Friday Calculations for New Film Synthesis Using JD-230 Amount used are 2.13 g of JD-230 6.46 g of Epoxy 0.86 g of TiO2 Thermal energy study As shown in Figure 1 the set up for the thermal energy study consisted of filling the aluminum dish with water, covering with foil, and placing the thermometer in the water. The Hotplate also has a thermocouple placed on the surface to record temperature. Figure 1. The study will start with the hotplate already warmed up to 120 degrees Celsius which as recorded by the Digi-sense was actual 104 degrees Celsius Readings of the water temperature are taken every 10 minutes for two hours. Table 1. Table 1. Shows the initial trial of this experiment. The results reflect a dish with no coating. It was observed that the temperature of the hotplate would decrease over time dropping as low as 89 degrees at around 40 minutes. It is believed that the air flow created by the hood vacuum, cools off the surface of the hotplate. It was decided that the thermal energy test would be completed on a bench top since only water is being worked with. The experiment was aborted, as reflected in the data. Analysis of XRD data The peaks were analyzed for identification of TiO2. First, the poweder XRD graph for an epoxy film is reported, followed by the pXRD of an epoxy and 10% TiO2 film. <br.
