Summary: This study analyzes the thermodynamic efficiency of the SnO2/SnO redox cycle using HSC Chemistry software. The results show that the demand for inert gas decreases as the reduction temperature increases, and the total thermal energy demand of the cycle is significantly influenced by the energy needed to heat the inert gas and the inert sweep gas. At a temperature of 2000 K, the SnO2/SnO CDS cycle achieves a solar-to-fuel energy conversion efficiency of 16.7%.

Summary: The catalytic conversion of CO2 through the reverse water gas shift reaction over transition metal nanoparticles supported on lanthanum was evaluated. The results showed that Cu-La2O3, Ni-La2O3, and CuNi-La2O3 catalysts exhibited maximum CO2 conversions of 57%, 68%, and 74%, respectively, at 600°C, with excellent stability and low carbon deposition rate. Among them, only the 1 wt% Cu-La2O3 catalyst showed 100% CO selectivity at all temperatures, while nickel-containing catalysts exhibited selectivity for methane along with carbon monoxide. This study demonstrates the promising potential of transition metal catalysts on lanthanum oxide support for the reverse water gas shift reaction and other hydrogenation reactions.

Summary: Additive manufacturing (AM) is important for developing complex and efficient parts, with fused deposition modeling (FDM) being the most commonly used method for polymer product fabrication. However, FDM has limitations in terms of weak mechanical properties and poor surface quality, which restrict the types of polymer materials that can be produced and affect its structural applications. This review aims to systematically document critical information on FDMed-polymer composite processing for part fabrication. Based on a literature review of over 150 high-impact research articles published from 2011 to 2021, this review covers the use of base and filler materials, as well as process parameters such as layer height, nozzle temperature, bed temperature, and screw type. FDM is widely used in biomedical, automotive, and other manufacturing industries, making this study an essential reference for future research in FDMed-polymeric composites.

Summary: The thermodynamic efficiency of MnFe2O4-based CO2 splitting (CDS) cycle was analyzed using HSC Chemistry software. It was found that increasing the flow rate of inert gas reduces the reduction temperature but increases the thermal energy required to drive the cycle due to the additional energy required to heat the inert gas. Incorporating gas-to-gas heat recovery significantly reduces the thermal energy required to drive the cycle and improves the solar-to-fuel energy conversion efficiency.
