Summary: Sb/Sb2O3 micro-composites can be obtained through a simple electrochemical deposition process, with patterns containing regions rich in Sb and Sb2O3 emerging under specific conditions. The formation of these patterns is proposed to be a result of complex interactions between electrochemical Sb deposition, chemical Sb2O3 precipitation, and convection patterns near the electrode. These findings contribute to a better understanding of electrochemical metal/oxide co-deposition and can aid in the design of advanced composite coatings.

Summary: The study investigates the formation mechanism of Sb/Sb2O3 composites using electrochemical, chemical, electron microscopy, and X-ray diffraction methods. It is experimentally verified for the first time that electrodeposition of Sb causes a local pH shift leading to the co-deposition of Sb2O3. A nucleation and growth model is proposed based on the results to explain the development of different Sb/Sb2O3 structures and compositions.

Summary: In this study, the evaporation process of antimony trioxide was investigated using nitrogen gas bubbling method at high temperatures, and it was found to be a second-order reaction. Increasing the temperature and gas flow rate while decreasing the lance height enhanced the evaporation rate and antimony recovery. The evaporated product was characterized and the residual slag was analyzed to understand the limitations of antimony trioxide evaporation.

Summary: In this study, three antimony(III) fluoride oxalates were successfully synthesized. These oxalates feature unique quasi-one-dimensional chain structures that induce large optical anisotropy. The results show that the optical anisotropy of these oxalates can be tuned through the synergetic interactions of templated cations and anionic functional groups.

Summary: A new barium molybdate, α-BaMo3O10, is reported with the study of the temperature-dependent phase transition from α-BaMo3O10 to β-BaMo3O10. The tunable linear and nonlinear optical properties induced by the phase transition are confirmed by both experimental and theoretical approaches. This work indicates that a small change in structure can induce tunable symmetries and thereby widely divergent optical properties.

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.
