Summary: To overcome the issues of liquid leakage and weak solar absorption in organic phase change materials (PCMs), researchers prepared a polypyrrole (PPy)-coated expanded graphite (EG)-based composite PCMs through chemical polymerization and physical infiltration methods. The integration of PPy and EG significantly enhanced the photothermal conversion and storage capability of polyethylene glycol (PEG). The composite PCMs exhibited high melting enthalpy, solidification enthalpy, shape stability, and latent heat storage retention even after 200 melting-freezing cycles, showing potential in solar energy utilization.

Summary: This study aims to evaluate the performance of a heat sink that combines active and passive cooling using synthetic jet and phase change material (PCM) respectively. The PCM provides a high latent heat value, while the synthetic jet induces vortex-based turbulent flow. The cooling characteristics of the heat sink with and without PCM were evaluated under three different operating conditions. The results show that the inclusion of PCM improves the performance of the heat sink, and the steady-state base temperature is 5 degrees Celsius lower for the heat sink with multiple-orifice synthetic jet compared to the one with a single orifice.

Summary: The hardness of materials greatly affects their machinability, which in turn affects power consumption, cutting tool life, and surface quality during component machining. In this study, annealed AISI 4340 alloy steel was machined using a coated carbide tool in a dry environment. The microhardness of annealed and non-annealed workpieces was compared, and a significant reduction was found in the microhardness of annealed samples. The microstructure examination revealed the formation of coarse pearlite in the annealed sample, indicating a reduction in hardness and improved ductility. A commercially available CVD multilayer coated carbide cutting tool was used to evaluate the surface quality, machining forces, flank wear, and chip morphology during the turning of quenched and tempered AISI 4340 alloy steel, with the machining speed, rate of feed, and depth of cut varied. The findings showed that the feed rate had a high impact on surface finish, followed by cutting speed. The study concludes that annealing is a cost-effective and economical process to enhance the machinability of alloy steel.
