Summary: Due to stricter standards for municipal wastewater discharge, further treatment is needed for nitrate in secondary effluent of wastewater treatment plants, which increases the costs. This study examined the possibility of simultaneous removal of nitrate and phosphorus from simulated secondary effluent using a sponge-iron-based denitrifying filter. The results showed that over 60% of the nitrate was reduced through abiotic nitrate reduction by the sponge iron. However, the sponge iron easily scaled and a little glucose was added to dissolve the rust and promote biological nitrate denitrification.

Summary: Volatile Organic Compounds (VOCs) are a type of pollutants that have gained significant attention in atmospheric and indoor air pollution issues as they are precursors for PM2.5 and ozone generation. The urgent problem of air pollution can be addressed through the removal of VOCs emitted from exhaust gases. Adsorption, with its advantages of high purification efficiency, low cost, and simplicity, is considered one of the most promising VOC abatement technologies. The effectiveness of VOCs removal relies heavily on the properties of the adsorbent, such as framework structure, pore properties, and surface cations. This paper analyzes the influence of these zeolite properties on VOCs adsorption performance, compares the performance of different zeolite adsorbents in the presence of water vapor, and summarizes the factors affecting the mass transfer kinetic properties of VOCs adsorption. Moreover, the paper provides an overview of zeolite honeycomb adsorbent applications in the industry, including multi-tower fixed bed adsorption and zeolite rotor adsorption.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
