“This activity develops the fundamental scientific principles enabling rational catalyst design and chemical transformation control.”
Fundamental questions
“What specific chemical nature of nano-catalysts drives high catalytic activity and selectivity?”
“What are the principals that regulate the “inverse design” of nanoscale building blocks to assure target properties”
