Plane protection: Alumina and titania improve the corrosion resistance of thermal barrier coatings to molten glass

By Lisa McDonald / August 18, 2023

Thermal barrier coatings protect engine components from extreme heat, but they can be damaged by the dust that gets sucked in and turned into molten glass. Previous studies found yttria-stabilized zirconia coatings doped with alumina and titania demonstrated improved corrosion resistance against this molten glass. Now, researchers in Turkey explored whether these additives could improve the resistance of ceria-stabilized coatings as well.

Hands-free defect engineering: Electric fields control motion of ceramic dislocations without need for mechanical loading

By Lisa McDonald / July 25, 2023

While some studies have demonstrated that electric fields and light exposure can affect the motion of dislocations in ceramics, the principal driving force of motion in these cases was mechanical stress. Now, an international group of researchers showed dislocation motion in a single-crystalline zinc sulfide can be controlled using only an external electric field.

Let there be light—aerogel-filled glass bricks provide translucency as well as insulation and loadbearing capabilities

By Guest Contributor / June 9, 2023

Glass block walls can be a desirable way to maximize natural light exposure in a building, but their thermal properties do not allow for the best energy efficiency. Researchers at Empa, the Swiss Federal Laboratories for Materials Science and Technology designed aerogel-filled glass bricks that are translucent as well as thermally insulating and strong.

Video: Solid acid fuel cells—a 20-year journey to advancing the hydrogen economy

By Lisa McDonald / May 17, 2023

There are many challenges to realizing a hydrogen economy that occur all along the supply chain. One challenge—converting the carrier molecule ammonia back into hydrogen—could be solved using solid acid fuel cells. ACerS Fellow Sossina Haile first developed this type of fuel cell in the late 1990s. Today’s CTT looks at Haile’s 20-year journey with her first Ph.D. student, Calum R. I. Chisholm, to realize the potential of this technology.
