Summary: In order to improve the thermophysical properties of Al alloy for thermal management materials, Cu-coated carbon fibers (CFs) were used as reinforcement to enhance the thermal conductivity (TC) and coefficient of thermal expansion (CTE) of Al-12Si. CFs/Al composites with different CFs contents were prepared by stir casting, and the effects of CFs volume fraction and Cu coating on the microstructure, composition, TC, and CTE were investigated. The results showed that Cu coating effectively improved the interface between CFs and the Al-12Si matrix, and the CFs/Al composites exhibited enhanced TC and CTE with increased CFs volume fraction. The CFs/Al composite with 8% CFs volume fraction displayed the best thermophysical properties, with a TC of 169.25 W/mK and a CTE of 15.28 x 10(-6)/K. The excellent thermophysical properties of CFs and good interface bonding were identified as the main contributors to the improved thermophysical properties of the composites. This research is expected to enhance the application of Al matrix composites in heat dissipation areas and provide a theoretical foundation.

Summary: In this paper, a simple material preparation method is proposed to meet the requirements of efficient heat exchange interface materials for spacecraft on-orbit modular assembly. Carbon nanotubes (CNTs) were dispersed on the surface of spherical copper (Cu) powder, and then the bulk was obtained by hot-pressing sintering. By removing the Cu on the surface, the CNTs can protrude from the surface to fill the pores at the interface, increasing the heat transfer channel and reducing the thermal contact resistance (TCR).

Summary: The temperature dependence of the electrical conductivity/resistivity of CNT networks is observed to be negative, especially for aligned CNTs (A-CNTs). This study investigates the role of three phenomena, namely the temperature dependence of the intrinsic conductivity of CNTs, the tunnelling resistance of their contacts, and thermal expansion of the network, on the temperature coefficient of resistance (TCR). The results show that the TCR of the CNTs themselves is the main factor influencing the TCR of the film, while the TCR of the tunnelling contacts and film thermal expansion have marginal effects.

The results show that mesoporous NiO exhibits the lowest overpotential and the highest turnover frequency and mass activity among the studied NiO electrocatalysts. Microporous NiO shows the highest specific surface area and electrical double layer capacitance, while nonporous NiO particles possess the highest specific activity and BET activity of the catalysts. It emphasizes the importance of morphology optimization for obtaining efficient OER electrocatalysts.

Summary: Electrocatalysis plays a crucial role in achieving sustainable chemical production using abundant resources and renewable energy. In this study, we developed an effective electrochemical method for producing hydrogen peroxide (H2O2) using only pure water and oxygen. Nickel (II) oxide (NiO) was used as the electrocatalyst for oxygen evolution reaction (OER) at the anode, while a conducting polymer poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT:PSS) drove the oxygen reduction reaction (ORR) at the cathode to generate H2O2. The conversion efficiency of the H2O2 electrochemical refinery was limited by unbalanced ionic transport in the solid electrolyte, but optimization of operation conditions achieved an efficiency of 80%.

Summary: Titanium tungsten carbide (TiWC) coatings were deposited using a combined high-power impulse and dc magnetron co-sputtering technique. The deposition phase involved heavy ion irradiation instead of external heating. The coating structures were established using titanium carbide targets in dc magnetron mode and tungsten carbide targets in high-power impulse mode. Varying the peak target current density (JT) controlled the intensity of W+ ion flux, which affected the film properties. The hybrid process resulted in dense TiWC coatings with a hardness above 30 GPa, comparable to films deposited using dc magnetron sputtering with external heating. The relative energy consumption was reduced by 77% compared to high-temperature dc magnetron sputtering.

Summary: The hardness and orientations of the primary αp and transformed βt grains in segmented chips obtained by turning Ti-6Al-4V bar were analyzed. The hardness of αp grains highly depends on the crystal orientation, varying from 4.5 GPa to 6.7 GPa. In the machined chips, αp grains showed similar hardness values while βt grains became slightly harder. The width of shear bands in the chips varied and smaller shear strain was correlated with larger shear cracks.

A physically-based computational micromechanics simulation tool has been developed to predict failure initiation in a composite ply under different strain rates. The simulation tool incorporates constitutive models calibrated with novel micromechanical testing techniques. By comparing simulation and experimental results, a change in failure initiation mechanism of the composite ply with strain rate has been identified and confirmed through observations of fracture surfaces.

Summary: The defect structures forming during high-temperature decomposition of Ti1-xAlxNy films were investigated through high-resolution scanning transmission electron microscopy. Two types of dislocations, misfit edge dislocations and a/6(112){111} partial dislocations, were found at the interface between TiN-rich and AlN-rich domains. The stacking fault energy associated with the partial dislocations decreases with increasing Al content, facilitating the phase transition of AlN-rich domains. Additionally, intersections of stacking faults were observed at the interface after annealing to 1100 degrees C, contributing to the hardening in Ti1-xAlxNy.

The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined.
