Summary: An integrated Dynamic Inventory for Mercury Emission (DIME) model was developed, improving the accuracy of emission estimates for primary sources in China. Long-term historical speciated Hg emission inventories for China were established, and three stages with distinct leading drivers were identified. The improved emission estimation methods, consistency in methodology for historical Hg emission inventories, and accurate spatial distribution of speciated Hg emissions provide a practical toolkit for the effectiveness evaluation of the Minamata Convention.

Summary: Artisanal and small-scale gold mining (ASGM) is a major contributor to mercury (Hg) emissions and it is crucial in addressing the Hg problem. Lack of accurate data on ASGM production, Hg use, and emissions necessitates the use of different approaches to estimate these variables. Global ASGM production ranges from 380-870 tonnes of gold annually, with a median value of 520 tonnes. Hg use in ASGM is estimated to be 640-1000 tonnes per year, with a median value of 892 tonnes. Consequently, ASGM emits 248-838 tonnes of Hg annually, with a median value of 615 tonnes. Discrepancies in the data calculated using different approaches were found, especially in countries with large estimates like China. A general estimation approach combining specific studies of dominant countries is recommended to obtain a more accurate global picture of ASGM activities. Developing a solid baseline, comprehensive future projection scenarios, and establishing international collaboration for guidance on ASGM are recommended for effective management of ASGM in the future.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.

Summary: Transition metal oxide (TMO)-based anodes attract attention for lithium storage due to their high capacity, easy synthesis, and improved battery safety. The electrochemical performance of TMO anodes can be significantly improved through configurational entropy optimization. For example, a high-entropy oxide (FeCoNiCrCu)(3)O-4 with low potential and high capacity is synthesized. In both half-cell and full-cell configurations, the (FeCoNiCrCu)(3)O-4 electrode shows excellent performance with high specific capacity and low discharge voltage.

Summary: In this study, antisolvent crystallization of L-aspartic acid (L-ASP) was optimized using response surface methodology (RSM) and a focused beam reflectance measurement (FBRM) tool. Important process parameters such as storage temperature, stirrer velocity, storage time, and solvent ratio were identified to significantly improve the yield and quality of the product, while chord length distribution (CLD) data was obtained through FBRM. The results showed that 2-propanol was a more effective antisolvent than methanol for L-ASP crystallization. Temperature was found to have a critical effect on crystal formation, with crystals forming between 298.15 and 303.15 K. ANOVA results confirmed the significant impact of all studied variables on the yield and CLD. The optimum crystallization conditions were determined as 18 h, stirrer velocity of 200 rpm, distilled water-formic acid/IPA ratio of 1:3 (v/v), and storage temperature of 298.15 K. A quadratic response surface model satisfactorily described the crystallization of L-ASP with an R2 of 0.99 and a deviation of 1.2%.

Summary: The surface atomic arrangement and defective structures of electrocatalysts play a crucial role in determining their catalytic activity and selectivity. In this study, alpha-Fe2O3 nanosheets with surface oxygen vacancies were synthesized and their oxygen vacancy concentration was varied to study their oxygen reduction reaction (ORR) performance. The results showed that increasing the oxygen vacancy concentration improved the ORR activity up to a certain point, but further increase deteriorated the crystalline quality and affected the performance.

Summary: Rechargeable sodium-air batteries have gained extensive attention and developed rapidly in recent years for electrochemical energy storage applications due to their low costs, abundance of precursor resources, and high energy density. However, challenges such as poor charge-discharge reversibility at the cathode and the formation of sodium dendrites at the anode still need to be addressed. Therefore, designing efficient and stable air cathode materials is crucial for the development and practical application of sodium-air batteries.
