Summary: The oxidation behavior of Ni-28W-6Cr-(0-0.190 wt%) Ce alloys at 850 degrees C was investigated. The addition of Ce significantly decreases the oxidation rate of the alloys and the thickness of the inner oxide scale. However, the decrease slows down when the Ce content reaches 0.190 wt% due to the formation of Ni-Ce phase. Ce is solid-soluted in the inner oxide and replaces Ni2+ to capture oxygen, inhibiting the formation of oxygen vacancies and oxygen diffusion.

Summary: This paper comprehensively considers multiple disaster-causing factors and geological variations, studies the long-term evolution trend of bank slopes with weak interlayers in reservoirs, calculates the reliability using the limit equilibrium method combined with the random field, and discusses the long-term effects of dry-wet cycles on reservoir bank landslides and the sensitivity analysis of the statistical parameters of the random field. The results show that the earthquake activity has the greatest impact on the failure probability of landslides, followed by the vertical fluctuation range of parameters and the coefficient of variation of the internal friction angle. The increase in failure probability under the action of dry-wet cycles is mainly caused by the reduction of parameters in the weak interlayer. The reliability evaluation method of reservoir bank slopes can be applied to predict the long-term stability of coastal banks.

Summary: This study proposes a theoretical model based on the actual properties of silver nanoparticles (Ag NPs) and compares the MeHg adsorption properties of different surfaces ((1 1 1), (1 1 0), (1 0 0), and (2 1 1)) through first-principles theoretical study. It is found that each surface of the NPs has a strong affinity for MeHg despite differences in surface structure. The electronic charge density difference, partial density of states (PDOS), and Bader charge were investigated to understand the electron interaction of adsorbed MeHg with each surface of Ag NPs. The calculated energy barrier of MeHg diffusion on the facets of Ag NPs follows the trend of (1 0 0) > (1 1 0) > (2 1 1) > (1 1 1). The potential application of Ag NPs in MeHg removal in liquids is highly promising due to their superior diffusivity and high affinity for MeHg. This work provides a new strategy for using metal NPs as scavenger materials for MeHg in liquid conditions.

Summary: In this study, a new strategy for tuning the lattice thermal conductivity (L) in isostructural half-Heusler compounds by adjusting the interaction strength between nested cations and the anionic framework is proposed. Through experiments and analysis, it is found that a synthesized 8-electron half-Heusler compound, MgCuSb, exhibits glass-like thermal conductivity despite common understanding for high L in 18-electron counterparts. The unusual suppressed phonon conduction in MgCuSb is attributed to native strong anharmonicity induced by atomic filling and a low-energy shearing vibration mode triggered by weak Mg-Cu bonding.

Summary: In this study, the researchers investigate how a female bird's personality traits, such as activity and breathing rate, can influence nest site selection at different spatial scales. They also examine the impact of nest site characteristics and female personality traits on clutch size and nest success during incubation. The findings reveal that activity and breathing rate are not associated with large-scale nesting habitat variables. However, at a smaller scale, more active females tend to choose nest sites with better lateral concealment. Females with higher breathing rates lay smaller clutch sizes, while those with lower breathing rates have higher nest success during incubation. This research highlights the link between personality and nest site selection in birds, and emphasizes the important role of female personality traits in reproductive success.

Summary: This study comprehensively investigated the electronic and optical properties of Mo2C loaded Au clusters (Aun @Mo2C) using the density functional theory (DFT) method. The results show that the Au clusters undergo a transition from a two-dimensional (2D) to three-dimensional (3D) configuration once the number of gold atoms reaches a certain threshold. The weakening of the interaction between the loaded Au clusters and Mo2C promotes this transition. Furthermore, an electric field guides the separation of electrons and holes towards the Au clusters, leading to enhanced surface light absorption capabilities under visible light. This study provides theoretical guidance for the design of metal-Mo2C materials by revealing the inherent relationship between their geometric, electronic, and optical properties.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
