Summary: This study investigates the effects of double-filling on the thermoelectric properties of the CexYb0.2-xCo4Sb12 skutterudite material system. By replacing Yb with Ce, the electrical conductivity, Seebeck coefficient, and power factor of the system were optimized. However, the power factor showed a downturn at high temperatures due to bipolar conduction. The lattice thermal conductivity of the skutterudite system was suppressed by introducing dual phonon scattering centers from Ce and Yb fillers. The highest ZT value of 1.15 was achieved for the Ce0.05Yb0.15Co4Sb12 sample at 750 K, and the thermoelectric properties could be further improved by controlling the secondary phase formation.

Summary: This article summarizes the recent progress in developing high-performance GeTe-based thermoelectric materials by exploring innovative strategies to enhance electron transports and dampen phonon propagations. Aliovalent doping/alloying and tunable electronic transport are proposed to decrease the carrier concentration and refine the band structure of GeTe. The addition of heavy Sb atoms, planar vacancies, and superlattice precipitates is explored to minimize the lattice thermal conductivity of GeTe. The strategies presented in this article are important for developing materials with enhanced thermoelectric performance.

Summary: This study focuses on the design and optimization of a high aspect ratio skutterudite (SKD) thermoelectric module (TEM) for a milliwatt Radioisotope Thermoelectric Generator (RTG). The aim is to enhance the output performance of the RTG by investigating the influence of TEM structure on temperature distribution and overall performance. It is observed that increasing leg length, selecting an appropriate cross-sectional area, and reducing the number of legs result in a larger temperature gradient within the TEM, ultimately improving the output power and conversion efficiency of the milliwatt RTG.

Summary: The introduction of laser shock peening (LSP) is effective in improving the mechanical properties of ceramics. Numerical simulations provide a convenient and efficient approach to examine the effects of different processing techniques on residual stress distribution. This study establishes a B4C-TiB2 ceramic model based on the extended Drucker-Prager model to investigate the effects of laser power density, the number of impacts, and laser spot overlapping rate on residual stress distribution and verifies the reliability of the simulation method through experimental data. The results indicate that increasing laser power density and the number of impacts can enhance surface residual compressive stress and reduce its depth; multiple impacts significantly reduce the depth of the residual compressive stress layer; a higher laser spot overlapping rate leads to a gradually increased and more uniformly distributed compressive residual stress in the processed area; a spot overlapping rate of 50% achieves the best processing effect.

Summary: In this paper, a monolithic Eulerian formulation is used to solve fluid-structure interaction problems in a nonclassical framework, and the micro-structural characteristics of fluid flow are studied by validating the results with classical benchmark solutions. The results indicate that increasing micro-rotational viscosity leads to significantly large micro-rotations in fluid flow, and the amplitude of oscillations is inversely related to the material parameters c(1) and mu(r). The snapshots of the numerical results at different times and general conclusions drawn from the results are presented.

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.
