Linguistic variables play a vital role in several qualitative decision environments, which decision-makers assume feasible linguistic values or criteria instead of single term for an alternative variable. The motivation the use words sentences numbers is that classification and characterizations are generally less precise than numerical ones. In this research article, we encourage fuzzy approach introduce novel concept known as m-polar variable (mFLV) to increase affluence based on (mF)...

The absence of intrinsic protons in proton-conducting oxides (PCO) is a significant challenge that limits the proton conductivity perovskites, such as Y-doped BaMO3 (M = Zr, Ce), ceramic fuel cells exhibit low (10-3 to 10-2 S cm-1 at 600 °C). Herein, we introduce photo-assisted synthesis method for incorporating into Al-doped ceria (AlxCe1-xO2-δ, x 0.2; M-ACO), leveraging open cubic fluorite structure and photo-activated radical reactions. Specifically, photon-generated hydroxyl reactive OH∙...
