Elasto-optical study of stabilized cubic zirconia

Physical Review B, 1995
The piezo-optical coefficients ${\mathrm{\ensuremath{\pi}}}_{11\mathrm{\ensuremath{-}}}$${\mathrm{\ensuremath{\pi}}}_{12}$ and ${\mathrm{\ensuremath{\pi}}}_{44}$ of cubic yttria-stabilized zirconia are measured as a function of wavelength, temperature, and yttria concentration.

Role of promoters over yttria‐zirconia supported Ni catalyst for dry reforming of methane

Energy Science & Engineering, 2023
Dry reforming of methane (DRM) bears great hope for the catalytic community as well as environmentalists for its potential to convert two greenhouse gases, CH4 and CO2, together into synthetic feedstock “syngas”.
