Summary: A trade-off between thermoelectric performance and cost-effectiveness enables commercial thermoelectric power generation. FeSi2 based materials have potential due to their low-cost and abundance, but their thermoelectric performance is inferior to other materials. This work presents a simple synthesis strategy, resulting in improved thermoelectric and mechanical properties.

Summary: AlSi11 matrix composites reinforced with SiC particles were fabricated by high pressure die casting assisted by ultrasonic mixing. A severe plastic deformation process was conducted on the composite using modified channel with twisted output (TCAP) at temperatures of 350, 400, and 450 ?. The TCAP tool enabled the refinement of the dendritic cast microstructure of the composite, resulting in a matrix with equiaxed a(Al) grains and twinned b(Si) particles. The TCAP process also caused a decrease in sample hardness due to dynamic recrystallization. The composite exhibited high plastic deformation and compressive strength when tested by compression tests.

Summary: Complex microstructures are crucial for thermoelectric materials to optimize power conversion efficiency. Grain boundaries (GBs) can reduce thermal conductivity but often decrease electrical conductivity. Recent research has shown that elemental segregation at GBs can make them electrically conductive and improve thermoelectric properties. In this study, InSb was added to Nb0.95Ti0.05FeSb to selectively modify the GBs' chemistry without increasing the carrier concentration of the matrix. The addition of InSb successfully increased power factor and zT of fine-grained Nb0.95Ti0.05FeSb, overcoming the negative impact of GBs on power factor.

Summary: In this study, a high hardness of 1.4 GPa and electrical conductivity of 1.52 x 107 S/m are achieved in an Al-carbon nanotube (CNT) composite using bare Al nanopowder as a metal matrix. The highly dispersed CNTs and controlled Al/CNT interface are achieved due to the similar size of Al nanopowder and less oxide layers on the Al particle surface. Fine Al4C3 grains formed at the Al/CNT interface enhance the hardness while the remaining Al/Al interface preserves the electrical conductivity. The electrical conductivity of the Al-CNT composites in this study is 33 times higher than that of Al-nanocarbons with the same hardness level.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
