This is the final report of the ARO project of gathering and sharing information on the role of stress and elastic strain fields on catalysis Stress Controlled Catalysis via Engineered Nanostructures. For this effort a workshop was organized and held at Brown University Providence, Rhode Island during June, 1- 2, 2015. It was planned and organized with help from the co-investigators of the ARO MURI program at Brown University and California State University Northridge Shouheng Sun, Andrew Peterson, Sharvan Kumar, Gang Lu and William Curtin. In addition, the workshop leveraged the opportunities of reviewing past and ongoing research on stress effects in catalysis in the U.S. and European institutions. Approximately fifty-nine 59 researchers participated in the workshop, including graduate students, postdoctoral researchers and faculty, from multiple disciplines including solid mechanics, materials science, physics, chemistry, chemical engineering and electrochemistry. As an outcome, a number of new ideas on possible future directions on the role of elastic strain on catalysis and ways to exploit the coupling were shared were shared across traditional disciplinary boundaries. The workshop was held successfully and has reached a conclusion that there is potential for exploiting the stress effect to design improved catalysts, possibly with less previous materials. It is also noted that hybrid approaches of experiments coupled with or guided by large scale computation is highly effective in discovering rich phenomena at multiple length and time scales. Some suggestions on future directions for research in this area are described in this report.
