Synthesis and Properties of Novel Calcia-Stabilized Zirconia (Ca-SZ) with Nano Calcium Oxide Derived from Cockle Shells and Commercial Source for Dental Application

Applied Sciences, 2020
Various oxides are used to stabilize zirconium oxide (ZrO2), but their superior hardness causes wear of the machining tool. Calcia-doped zirconia has been studied but reports on properties suitable for dental application are lacking.

Design of High‐Performance MnCo1.5Cu0.5O4 Spinel Contact Material with Optimized Electrical Conductivity and Thermal Stability for Solid Oxide Electrolysis Cells by Cu Doping

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Cu‐doped spinel MnCo1.5Cu0.5O4 exhibits excellent conductivity and stability as SOC contact material. After 1000‐h aging at 850 °C, the contact layer maintains a 10 mΩ cm2 ASR value, and a single‐cell stack achieves a H2O/CO2 co‐electrolysis power density of 0.52 W cm−2.
