Fabrication of Functionally Graded and Aligned Porosity in Thin Ceramic Substrates With the Novel Freeze–Tape-Casting Process
TL;DR: In this paper, a modified tape-casting process was used to construct pore structures for use as solid oxide fuel cell electrodes, catalysts, sensors, and filtration/separation devices.

Mechanism for SOFC anode degradation from hydrogen sulfide exposure
TL;DR: In this article, the authors show that hydrogen sulfide leads to nickel migration and depletion in the anode, thereby compromising electrical conductivity and cell performance, and they also reveal a mechanism for the long term permanent degradation.

TL;DR: In this article, a bulk-type all-solid-state batteries with composite positive electrodes, using Alsubstituted Li7La3Zr2O12 (LLZO) as the solid electrolyte, have been demonstrated for the first time.
Comparative toxicity of nanostructured alumina and a commercial inert dust for Sitophilus oryzae (L.) and Rhyzopertha dominica (F.) at varying ambient humidity levels
TL;DR: Stadler et al. as discussed by the authors presented a study of the relationship between the biomedical field and the Nacional de Investigaciones Cientificas and Tecnicas.
