The U.S. National Science Foundation (NSF) provides major funding to the National Nanotechnology Infrastructure Network (NNIN) in support of nanoscale science and engineering research. In addition, NSF has directed NNIN to increase awareness among researchers of social and ethical issues (SEI) related to nanotechnology. By completing the Ethics Module that follows you will help NNIN fulfill its SEI mission. All responses will be kept strictly confidential. They will not be linked to specific individuals and will be analyzed only in groups. The questionnaire should take about 18 minutes to complete.
