Summary: The study successfully prepared a new type of silicate bonded biochar with good adsorption performance and separation and recovery characteristics by applying silicate gel materials to the preparation of biochar. The silicate bonded biochar maintained good mechanical properties after three rounds of soil remediation, with compressive strength remaining between 210 and 270 N. The total Cd and available Cd in the soil were significantly reduced, and both SBC and MSBC showed high rates of reuse and adsorption regeneration, effectively decreasing Cd content in wheat.

Summary: In this study, peanut shells were used to prepare biochar, which was then aged using artificial simulated aging. The effectiveness of biochar for the removal of Pb and CIP, both individually and simultaneously, was investigated. Different aging methods were employed to study the physicochemical properties of the biochar. The results showed that aging inhibited the adsorption of ciprofloxacin on biochar, while the effect on Pb adsorption was insignificant. The study highlights the importance of considering regional climatic factors and target pollutant species when using biochar for pollutant removal.

Summary: This study evaluated the chemical form variation of Mn in Phytolacca acinosa Roxb. residue under different pyrolysis temperatures and its contribution to decontamination efficacy of lead (Pb(II)) and tetracycline (TC). The results showed that pyrolysis temperature is a crucial factor in the bioavailability of Mn and other heavy metals in the biochar, with temperatures under 450 degrees C being most suitable for reutilization. The Mn-enriched phytolaccaceae biochar exhibited preferential sorption towards Pb(II) and TC in the single system, while binary adsorption demonstrated a bridging effect between Pb(II) and TC within a limited concentration range for joint decontamination.

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.
