Phonon Engineering in 3D-Printed Porous Scaffolds for Catalytic Conversion

PROBLEM: A printed catalytic scaffold concentrates reaction heat in its reactive pores, and the surrounding pore network's phonon scattering decides whether that heat is carried away or trapped at the catalyst, changing reaction pathways and support stability. A proposal that names the catalyst and the print geometry but not the thermal transport leaves the most consequential variable unstated, so two identical-looking scaffolds can convert differently. Reviewers need the phonon reasoning in the proposal.

SOLUTION: IBM Cloud Ideas would host printed catalytic proposals that state the pore geometry, the phonon-interface rationale for heat flow from reactive pores, the DFT reactant-binding prediction, and the conversion and regeneration test plan together. Reviewers could compare proposals on thermal grounds and request the missing heat-flow reasoning before a build is approved.
