Summary: The Fe-CuS/C catalyst exhibits a high NH3 production rate in the nitrogen reduction reaction, but rapid degradation of the catalyst hinders precise investigation in longer measurements. However, when the degradation effect is mitigated, the NH3 production rate is enhanced with increased overpotentials.

Summary: This study used a combination of experimental investigation and statistical analysis to study iron precipitation from wet-process phosphoric acid for the first time. The results showed that calcium carbonate and calcium hydroxide were the most effective additives for removing iron ions. The iron precipitation process was found to be an endothermic reaction. The formed precipitates were mainly Fe(OH)3, alpha-Fe2O3, alpha-FeOOH, and FeCO3.

Summary: This study investigated the influence of Cu and Zn on the precipitation of struvite, showing that the addition of Cu and/or Zn can disrupt the crystalline growth of struvite and promote the formation of amorphous phases. When Cu and Zn coexisted, there was competitive binding of PO4 between the two metals. Overall, the presence of Cu and Zn during struvite formation greatly affects its content by forming different metal-containing products.

Summary: A self-assembly method was developed to synthesize cuprous chloride/copper chloride hydroxide composites for investigating their hydrogen sulfide (H2S) removal performances. It was found that the Cu intermediate product by Fe reduction reacted with CuCl2 to form CuCl, which then self-assembled with CuCl2 and H2O to generate copper chloride hydroxides shell layer, leading to increased H2S adsorption capacity. Extensive analyses revealed the sulfidation reaction mechanism of CCCCHs, showing that the decomposition of CCHs enhanced the H2S treatment capacity substantially.

Summary: The diversion of organic waste through anaerobic digestion presents an opportunity to recover valuable nutrients like nitrogen and phosphorus, with municipal sewage sludge being the largest potential source for recovery. The nutrient recovery rates vary for different end products, with liquid fertilizer, struvite, and compost contributing to offsetting synthetic fertilizer demand in California to different extents. In a profitable build-out scenario for anaerobic digestion facilities, recovered nutrients could offset a significant portion of the state's synthetic fertilizer demand.

Summary: Chemical looping ammonia synthesis (CLAS) using Mo2N as nitrogen carrier was demonstrated to be an effective and sustainable method for ammonia generation. The two-step CLAS showed high N release/fixation efficiency and achieved a higher NH3 production rate compared to the thermo-catalytic ammonia synthesis route catalyzed by Mo2N. The study also confirmed the stability and feasibility of using Mo2N as an NC during the CLAS process.

Summary: This study investigated microbial adaptation to high ammonia concentrations during anaerobic digestion under psychrophilic and mesophilic conditions. It found that diversity reduced under psychrophilic conditions when adaptation occurred successfully, while the microbial community became more diverse under mesophilic conditions with ammonia inhibition. The study also identified Methanocorposculum as a robust hydrogenotrophic methanogen at high ammoniacal concentrations under psychrophilic conditions for the first time.

Summary: Black arsenic phosphorus (b-AsP) is a promising material for midwave infrared photodetectors, but the lack of high-quality crystal synthesis strategy and susceptibility to oxidation are obstacles. In this study, a stable strategy for synthesizing highly oriented b-AsP crystals was proposed, achieving superior crystal quality with low oxygen content on the surface. Additionally, the characteristics of interlayer synchronous oxidation and surface hydrolysis of b-AsP were revealed for the first time, providing guidance for the synthesis and application of b-AsP materials.
