How renewable energy consumption and digitalization contribute to environmental sustainability: Evidence from One Belt One Road countries.

This study investigates the crucial relationship between renewable energy consumption and digitization to drive sustainable development, specifically focusing on One Belt One Road (OBOR) countries. Using OBOR countries, panel data is collected over 24 years from 1996 to 2019.An enhanced System GMM estimator is employed in order to overcome challenges associated with methodology such as endogeneity, homoscedasticity and serial correlation which ensures reliable and robust payoff results.

A novel yttrium stabilized zirconia and ceria composite electrolyte lowering solid oxide fuel cells working temperature to 400 °C.

Reducing the working temperature and improving the ionic conductivity of electrolytes have been the critical challenges for the gradual development of solid oxide fuel cells (SOFCs) in practical applications. The researchers all over the world attempt to develop alternative electrolyte materials with sufficient ionic conductivity. In this work, YSZ-CeO composite material was used as electrolytes in the construction of symmetrical SOFCs.

Composite electrolyte used for low temperature SOFCs to work at 390°C.

A combination of yttria stabilized zirconia (YSZ) and Ba(NO) commercial powders was used as electrolytes in the construction of symmetrical SOFC. As X-ray diffraction pattern and Raman spectra revealed, the YSZ-Ba(NO) electrolyte converted into YSZ and yttrium-doped barium zirconate (BZY) composite at 450°C in hydrogen atmosphere. The power maximum () of YSZ-BZY based fuel cell can reach 634.

Nb-doped LaSrFeO as an electrolyte for intermediate-temperature solid oxide fuel cells.

It is one of the effective strategies to develop intermediate-temperature solid oxide fuel cells (IT-SOFCs) by looking for alternative electrolyte materials that can maintain or even improve current cell efficiencies while reducing operating temperature. In this study, by rationally introducing pentavalent Nb on the B-site of LaSrFeO (LSFO), a serial of novel perovskite LaSrFeNbO (LSFNb, x = 0.1, 0.
