Nanotechnology Engineer Interview Questions

Sample answer to the question

During my time as a Nanotechnology Engineer, I encountered an issue while conducting an experiment on nanoparticle synthesis. The experiment was not yielding the desired results, and the nanoparticles were not forming as expected. To troubleshoot the issue, I first reviewed the experimental procedure and compared it with previous successful trials. I realized that there was a discrepancy in the reactant concentrations. I then adjusted the concentrations to match the previous successful trials. After making the necessary changes, I repeated the experiment and closely monitored the reaction. I observed a significant improvement in the formation of nanoparticles. To ensure accuracy, I analyzed the nanoparticles using electron microscopy and surface characterization techniques. The results confirmed that the issue was successfully resolved and the experiment was a success.
