Optimized tape casting process creates lithium metazirconate thin films for use as solid-state electrolytes

Lithium metazirconate (LZO) has demonstrated promise as an electrode coating in solid-state batteries, and some researchers are exploring the use of LZO as a solid-state electrolyte itself. However, to date, all electrochemical testing on LZO for this application has been performed on pressed discs rather than thin films. Researchers in Argentina and Spain developed an aqueous forming route to obtain LZO films by tape casting.

Training the next generation of builders—first large-scale construction 3D printer in the Buckeye State arrives at OSU

Further expanding the use of 3D printing in construction will require training the next generation of builders on these techniques. A new research partnership between The Ohio State University and 3D-printing construction company Pantheon Innovative Builders will help provide this training through use of COBOD International’s construction-grade BOD2 printer.

Black silicon wafers significantly improve efficiency of ultrathin solar cells

Reducing the thickness of silicon wafers in solar cells below 40 μm typically results in decreased performance. Using black silicon for the wafer, however, which has a textured surface structure, can improve the wafer’s absorption capabilities. Researchers in Spain and Finland demonstrated this improvement by using ultrathin black silicon wafers to create interdigitated back-contact solar cells.

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

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.
