Summary: This study analyzes the reaction characteristics and mechanism of self-exothermic Al-ZnO system powder, as well as the influence of temperature, reaction atmosphere, weight ratio, and particle size. The research finds that when the powder composition ratio is closer to the equilibrium stoichiometry and the particle size is larger, the self-exothermic reaction heat release decreases, the reaction stability improves, and the intermetallic reaction becomes more apparent. Moreover, the reaction products are significantly influenced by different reaction atmosphere environments, while the reaction point remains less affected. The Al-ZnO system powder exhibits a wide moderating capability.

Summary: The mechanism of pore formation associated with intermetallic reaction in sintered Ti50Al50 alloy was studied using two different heating rates, 1°C/min and 10°C/min. The heating rate had a significant effect on pore parameters and intermetallic reactions. Pore size and porosity increased with the extent of exothermic reactions during sintering. Different intermetallic phases formed at different temperatures due to reaction between Ti2Al5 phase, Al, and Ti. The higher heating rate of 10°C/min resulted in considerable changes in thermal and volume expansion compared to 1°C/min. Thus, the heating rate during sintering greatly influenced the porous properties of Ti50Al50 by controlling the degree of exothermic reactions.

Summary: It has been found that the particle size of Ni-Al composite powders plays a crucial role in controlling the exothermic reaction for the formation of Ni-Al intermetallics during plasma spraying. Larger powder particles make it difficult for the reaction to complete, while smaller powder particles allow the exothermic reaction to occur rapidly, contributing to the development of the self-bonding effect in the coatings. The higher droplet temperature resulting from the exothermic reaction contributes to the adhesive or cohesive strength of the coatings.

Summary: A large-scale synthesis method for phosphorescent carbon nanodots (CNDs) has been demonstrated via precursors' self-exothermic reaction at room temperature, showing comparable fluorescence and phosphorescence properties with other synthesis methods. The exotic atom doped sp(2) hybridized carbon core serves as an emissive center to facilitate the intersystem crossing, enabling tunable phosphorescence lifetimes from 193 ms to 1.13 s at different temperatures. This method opens up a new avenue for room temperature fabrication of phosphorescent CNDs.

Summary: The study investigated the effects of particle size on gases emitted from weathered coal under high-temperature oxygen deficiency, revealing that the concentration of indicator gas did not monotonically increase or decrease with the change in particle size. A particle size of 3 mm was determined to be the critical size during high-temperature oxidation of weathered coal. The results provided a pivotal theoretical basis for the early prediction and scientific prevention of the spontaneous combustion of weathered coal.

Summary: AlN ceramics were prepared from two kinds of powders by combustion synthesis at low temperature. The sintering performance, including density variation, thermal conductivity, X-ray diffraction pattern, and morphology, were compared and evaluated. AlN ceramic prepared from powders with NH4Cl as an additive showed higher thermal conductivity under the same sintering system compared to those with H2O as an additive and commercial Tosan powder, demonstrating great potential for commercial applications in low-cost AlN ceramics.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

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.
