On March 25, 2014, the National Nanotechnology Initiative (NNI) published a supplement to President Obama’s 2015 budget request submitted to Congress on March 4, 2014.  The supplement provides a description of the activities underway in 2013 and 2014 and planned for 2015 by the federal government agencies participating in the NNI, primarily from a programmatic and budgetary perspective.  NNI states that it is based on the NNI Strategic Plan and reports actual investments for 2013, estimated investments for 2014, and requested investments for 2015 by Program Component Area (PCA). NNI states that the President’s 2015 budget provides over $1.5 billion for NNI, “reflect[ing] nanotechnology’s potential to significantly improve our fundamental understanding and control of matter at the nanoscale and to translate that knowledge into solutions for critical national issues.” According to NNI, the investments in 2013 and 2014 and proposed for 2015 “continue the emphasis on accelerating the transition from basic R&D to innovations that support national priorities, while maintaining a strong base of foundational research, to provide a pipeline for future nanotechnology-based innovations.”
