Summary: In this research, a beta-FeSi2-based thermoelectric module is used to extract waste heat energy from hot metallurgical products like hot rolled slabs. The maximum power output obtained is 0.91 W at 1250 K, with a power density of around 12.64 mWcm(-2). Three-dimensional views of various outputs are represented using ANSYS19.2 software, and mathematical relations are used to estimate potential circuit configurations to increase power output.

Summary: Concentrated solar power plants face corrosion issues caused by salt, and modeling is necessary to predict their lifetime. In addition, even slight temperature variations can cause changes in microstructure due to phase transformations, thus affecting the formation energy of materials. This study examines the corrosion of molten carbonates, a potential heat transfer fluid for CSP applications, on H230 alloy at temperatures of 700°C, 750°C, and 800°C for up to 1000 hours in an air atmosphere. The diffusion processes involved in the corrosion mechanism were analyzed and modeled through microstructural characterizations and thermogravimetric studies.

Summary: This study investigated the high temperature lubrication effect of different alkaline carbonates (high-temperature ionic liquid) and found that the lubrication properties are alkaline species dependent, with potassium carbonate showing better lubrication than sodium and lithium carbonate. At high temperatures, alkaline carbonates decompose and react with iron oxide to form alkali ferrites with promising anti-wear properties. Li2Fe3O4 exhibits better lubricity compared to NaFeO2 and KFeO2.

Summary: This paper reports the design of a bi-gradient polymer composite dielectric using an integrated framework based on the phase field model, which can predict the charge-inhibiting behavior of composite dielectrics. It is found that the traps provided by the functional organic fillers significantly suppress the breakdown initialization process. The experimental results show that the bi-gradient composite dielectric has high energy density (5.51 J cm(-3)) and high charge-discharge efficiency (90%) up to 200°C. This research provides a strategy to predict the high-temperature energy storage performance of polymer composites and helps broaden the scope of data-driven materials design based on phase-field modeling.
