Summary: In this study, copper oxide nanoparticles (CuO NPs) were synthesized using plant extract as stabilizing agent and characterized using various techniques. It was found that CuO NPs can act as a catalyst for NC, reducing activation energy and slightly decreasing peak temperature. The thermal decomposition process of NC and NC-CuO composites was classified using kinetic methods, showing potential for practical applications.

Summary: Solid-state thermal control devices have emerged as potential candidates for enhanced thermal management and storage over the past decade, showing sharper nonlinear dependencies on direction and operating temperature compared to traditional passive devices. They also offer the advantages of no moving parts and compactness over traditional active thermal management devices. This article reviews recent progress in four broad categories of such devices: diodes, switches, regulators, and transistors, discussing their operation principles, material choices, and performance metrics. New theoretical architectures are also explored in the discussion.

Summary: Iron oxide nanoparticles were successfully prepared via mechanochemical synthesis from three different reactive systems. The study investigated the effects of various iron salts and metallic iron on the properties of the nanoparticles, and determined high magnetization of the obtained iron oxide nanoparticles across a range of temperatures. The presence of metallic iron was found to be crucial in the formation of magnetic phases in the nanoparticles.
