Summary: This study evaluated the feasibility of fabricating nanostructured Cu/Al/Ag multi-layered composites by accumulative roll bonding (ARB), and developed a theoretical model to predict the tensile strength of the composites. It was found that the tensile strength was enhanced by ARB progression but then reduced, while the electrical conductivity decreased slightly at initial ARB cycles but intensified at final cycles. In conclusion, the study demonstrated the advantages of ARB in fabricating multi-layered nanocomposites and the accuracy of the developed model in predicting tensile strength.

Summary: FePS3, a layered magnetic van der Waals compound, exhibits a Mott insulator-metal transition under applied pressure, accompanied by changes in crystal symmetry and magnetic structure. To understand these transitions, it is essential to study the crystal structure as a function of pressure. Through single-crystal and powder x-ray diffraction measurements, we have confirmed that the highest-pressure transition involves a collapse of interplanar spacing and an increase in symmetry from monoclinic to trigonal space group, supporting one model over competing alternatives. Our findings provide crucial insights into the high-pressure behavior of these materials and demonstrate a comprehensive methodology for investigating complex two-dimensional material structures under pressure.

Summary: This study evaluated the microstructure evolution in two arc-welded multi-principal element alloys using electron microscopy and high energy synchrotron X-ray diffraction coupled with thermodynamic calculations. By correlating microhardness maps with microstructure characterization, the strengthening phases in the welded materials were identified, aiding in fine tuning of the alloy microstructure for targeted strengths. A comparison between thermodynamically predicted microstructure and actual welded joints highlighted the difficulty of predictions in complex, scarcely studied multi-principal element systems.

Summary: The total stacking fault energy (SFE) of GH3536 superalloy was divided into three terms for investigating the temperature dependence. The results revealed a significant temperature dependence for SFE, which explains the occurrence of twinning during plastic deformation at cryogenic temperature. The estimated SFE at ambient temperature matches well with experimental measurement, offering insights into the deformation mechanisms of fcc alloys with low SFE and paving the way for novel materials with excellent resistance to cryogenic temperature.

Summary: Piezoelectric materials are crucial in various applications, but there are still unanswered questions regarding their physical origin. This study utilizes high-energy synchrotron radiation X-ray diffraction to investigate the response of BiFeO3-BaTiO3 piezoelectrics and the intrinsic/extrinsic contributions to electric fields. The findings suggest that Bi3+-ion disordering plays a significant role in realizing piezoelectricity and nanodomains, and there is an extrinsic effect on the rearrangement of nanodomains. Understanding these effects is important for the development of next-generation Bi-based lead-free piezoelectric ceramics.

Summary: Novel manganese nitrides doped with rare-earth elements (Y, Er, Tm, Yb) were synthesized and evaluated for their oxygen reduction reaction (ORR) catalytic activities in an alkaline solution. The distribution of manganese and ytterbium on a nanometer scale was observed, and the nitride catalysts with about 1% Yb/Mn ratio exhibited enhanced ORR activity and high affinity toward OH-. Manganese nitrides containing small amounts of various rare-earth elements (Y, Er, Gd, Tm) were also synthesized, leading to improved catalytic activities. This work presents new strategies for synthesizing metal nitrides with rare-earth elements and enhancing the ORR catalytic activities of metal nitrides.

Summary: The superconducting properties and structural parameters of LaO0.5F0.5BiS2-xSex, a BiCh2-based layered superconductor (Ch: S, Se), were investigated. Increasing the Se concentration led to an increase in the superconducting transition temperature (Tc) and the induction of bulk superconductivity. A larger Gruneisen parameter (gamma G) was observed when x>=0.4, indicating improved superconducting properties. The study also found a positive correlation between gamma G and Tc in Se-poor samples of REO0.5F0.5BiS2 (RE = Pr, Nd). Additionally, specific heat analyses revealed the existence of a low-energy optical phonon mode in LaO0.5F0.5BiS2-xSex.

Summary: The temperature-dependent structural variations of lead titanate (PT) ceramic coatings formed at room temperature via aerosol deposition were investigated to assess the stability of the ferroelectric phase. The results showed that the as-deposited film had a c-axis orientation, which may be attributed to the anisotropic structural characteristics of the crystal. The aerosol deposition method stabilizes the ferroelectric phase up to a higher temperature, although the spontaneous polarization is suppressed.

Summary: We demonstrate the thermoelectric transport properties of the Zintl arsenide EuCuAs. The crystal structure of EuCuAs consists of a covalently-bonded honeycomb-type CuAs network sandwiched by nearly divalent Eu ions. Undoped EuCuAs exhibits a relatively high power factor but a limited dimensionless figure-of-merit due to high lattice thermal conductivity. First-principles calculations predict that heavy hole-doped EuCuAs can exhibit axis-dependent conduction polarity, enabling the construction of transverse thermoelectric devices.

Summary: Zn-Al layered double hydroxides (LDHs) have been found to have activity in electrochemical reduction of carbon dioxide (CO2ER) to form carbon monoxide (CO). The interaction of CO2 with Zn-Al LDH showed different carbonates evolution compared to other LDHs, indicating a different electrocatalytic activity. In gas-phase CO2ER, Zn-Al LDH exhibited a higher partial current density for CO formation compared to liquid-phase CO2ER.

Summary: A new type of glassy solid electrolyte was prepared by doping tetramethylammonium iodide (TMAI) in Li7P2S8I. The doping of TMAI in Li7P2S8I did not decrease the ionic conductivity with an increase in the doping content up to x = 0.2. The cycling performance of all solid-state cells with Si as the electrode was improved by increasing x, reaching a capacity of approximately 2000 mA h g(Si)(-1) after 10 cycles using the electrolyte with x = 0.2. This hybrid electrolyte is considered to suppress electrode cracking caused by large changes in Si electrodes during charge and discharge.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
