New method shows promise repairing localized damage in thermal barrier coatings

By Lisa McDonald / July 12, 2022

Repairing localized damage in thermal barrier coatings on aircraft turbine blades can require full coat removal and reapplication to avoid blocking cooling holes in the blade. Forschungszentrum Jülich researchers proposed a new laser-cladding-based additive manufacturing technique that shows promise repairing localized damage without the need for full coat removal.

Characterizing oxide catalysts: Methanol chemisorption quantifies active sites

By Lisa McDonald / January 25, 2022

The ability to count the number of active sites on oxide catalysts and thereby determine the reaction turnover frequency has developed very slowly in comparison to metal catalysts. In a recent paper, Lehigh University professor Israel E. Wachs argues for further developing the methodology of methanol chemisorption to address this situation.
