The conversion of electrical energy into a chemical energy carrier in the form of hydrogen, carbon monoxide and synthesis gas can be achieved with high efficiency by using the solid oxide electrolysis technology. However, long term degradation issues, especially of the fuel electrode remain a challenge that must be resolved. [...]

This work focuses on the analysis of the performance and degradation behavior of Ni-cermet and Ni-free perovskite materials for the fuel gas electrode under steam, CO$_2$, and co-electrolysis conditions. Degradation tests of commercial solid oxide cells with a Ni-8YSZ fuel electrode were carried under a constant current density of $-1$ A $\cdot$ cm$^{-2}$ for 1000 h. [...]

Spin polarization is a fundamental concept in condensed matter physics, with key implications for theory and spintronics. Unlike charge-based electronics, spintronics exploits electrons’ intrinsic spin, enabling faster and more energy-efficient information processing. [...]

Uncontrolled fires in buildings pose significant threats to occupants, the environment, property, and the continuity of operations. Fire risk assessments are critical tools used to identify hazards, determine the likelihood of their occurrence, assess potential consequences, and propose mitigation measures. [...]
