Prior to meeting with Dr. Reinhard, Ned and I had discussed several testable variables but do to the uncertainty of the science and the expected outcome we were not sure if they were feasible. As we discussed our project with Dr. Reinhard we gather data that allowed us to begin a design for our project. We were also able to discussed testable variables with greater detail, and develop a strong testing plan. In addition to creating the testing plan, New also forwarded the information to the graduate students we have been working with Bo Yan and Yan Hong. After the feedback they provided us with, we still have a little more research to do, but feel confident that our testing plan is do able.
Ned and I have decided that we are going to test
1) the exposure time of the explosive material vapor on the sensor chip.
2) the concentration of the explosive material vapor that is exposed to the sensor chip.
3) the location of the concentration so that the molecules are exposed to a more "typical" environment.
4) the distance from the source of the explosive material to the sensor chip.
In oder to do this we need to
1) Hold the concentration of the explosive material constant at 15 ppb.
2) Continue to use the NaOH solution on the surface of the sensor chip.
3) Hold exposure time the same for all tests. 5 minutes.
4) Vary the distance, from 0 - 3 feet. and varying distances between.
5) determine the rate of evaporation of the solution.
In order to analyze the data we are going to learn how to use the microscope with Bo Yan.
Overall, this week was very productive. I have learned a great deal and we have made great progress with the our robot and the overall design of the project.
