While fused filament fabrication has the potential to fabricate lithium-ion batteries with tailored geometries, the high amount of polymer often included in the electrodes can limit application. University of Castilla-La Mancha researchers attempted the required debinding/sintering treatment to achieve full ceramic electrodes via this additive manufacturing method.

The use of transparent ceramics as a gain medium in lasers is an evolving field, and there is still much to learn about how processing parameters affect the ceramics’ performance. Researchers in Singapore and China published two papers investigating the possible effects of a standard sintering aid and dispersant on lasing performance.

Fabricating metal-organic frameworks in a glassy phase is a successful way to synthesize these materials for bulk production. However, some MOFs decompose before reaching the melting temperature and so cannot be turned into a glass. Researchers in Germany and the U.K. found a way to melt these unmeltable MOFs by adding ionic liquid to the compound.
