Summary: The research found that directionally solidified Cu-Fe-Cr-Ag alloy exhibited excellent mechanical properties and conductivity, with higher tensile strength and conductivity compared to upward continuously casted alloy after cold drawing and isothermal aging. The finer and more uniform Fe dendrites, Cu-Ag eutectic structure, and distribution of Ag around the material contributed to the superior comprehensive performance of the directionally solidified Cu-Fe-Cr-Ag alloy.

Summary: The effects of minor Ce addition on the microstructures, tensile properties, and electrical conductivity of Al-Fe alloy were investigated. The results showed that Ce addition led to α-Al refinement, modification of the Al13Fe4 minority phase, and decrease in Si solid solubility. The grain refinement had negligible influence on the tensile strength, while the ductility and conductivity were simultaneously improved. The modification of the Al13Fe4 minority phase improved ductility, and the decrease in Si solid solubility increased electrical conductivity. This study provides a strategy to enhance both tensile properties and electrical conductivity of aluminum alloy.

Summary: Fe-Mn-Si-Cr-Ni shape memory alloys (SMAs) were prepared by mechanical alloying and discharge plasma sintering. The effects of milling time on the microstructure evolution, mechanical properties, superelasticity, and corrosion resistance of Fe-Mn-Si-Cr-Ni SMAs were investigated. The increase in milling time promoted the phase transition during the sintering process and affected the superelasticity and corrosion resistance of the alloy.

Summary: The high-temperature strength of the Cu-4.06Cr-1.25Nb alloy fabricated by the atmospheric melting method was significantly improved compared to other Cu-based alloys. The alloy fabricated by spark plasma sintering (SPS) exhibited high tensile strength at room temperature due to the presence of refined grains, but its high-temperature strength was lower due to the crack sources and propagation paths formed by grain-refined/coarsened boundaries.

Summary: A novel non-equiatomic high entropy alloy (HEA) Al15.85Fe11.15Co32.11Cr10.76Ni30.13 was fabricated using a powder metallurgy method. The HEA exhibits a dual-phase microstructure consisting of face-centered-cubic (FCC) and body-center cubic (BCC) phases. It possesses high compressive yield strength, fracture strength, fracture strain, and strength at high temperature due to the uniform dispersion of L12 and B2 nanoprecipitates in the FCC and BCC phases, respectively. This finding provides guidance for the development of high-performance structural materials with a balance of strength and ductility for industrial applications.

Summary: In this study, a CO2 sensor capable of low-temperature operation was fabricated using an open-channel-type thin-film transistor structure with a polar surface of an oxide semiconductor. The sensor showed a sensitivity 2.9 times greater than that under an inert N2 atmosphere at an operating temperature of only 150 degrees C. The results suggest that TFTs fabricated with polar surfaces of oxide semiconductors are useful for gas-sensing applications.

Summary: In this study, a defective system of V-doped Fe2O3 with Pt as a cocatalyst was used for photoelectrochemical water oxidation. The defects in the VFPt-2.5 photoanode were characterized by XPS and EPR analyses. The SEM and TEM analyses revealed that the electrodeposited V-doped alpha-Fe2O3 had a nanosized morphology with an average diameter of 12 nm and a thickness of 300 nm. Under light irradiation, the VFPt-2.5 photoanode achieved a remarkable onset potential and photocurrent density. The stability test showed that Pt helped overcome the charge recombination caused by surface states.
