Summary: Polyacrylamide (PAAm) hydrogel-based nanocomposites were prepared with the addition of graphene, kaolin, or laponite as possible adsorbents for organic dyes. The morphology of the hydrogels was controlled by varying water content, and the composition of the nanocomposites was modified by changing the type and amount of additive. The physicomechanical properties of the nanocomposites were influenced by hydrogel morphology and additives, with higher water content leading to less rigid nanocomposites, and the additives affecting rigidity differently. The adsorption properties of the nanocomposites varied depending on the additive, with laponite showing the most significant increase in adsorption capacity.

Summary: The presence of nanoparticles in drinking water raises concerns about their potential risks to human health and the efficacy of water treatment plants in removing them. This study examines the efficiency of granular activated carbon (GAC) in removing CeO2 nanoparticles. The results show that GAC has a good affinity for nanoparticles, with higher adsorption capacity and removal efficiency in lake water compared to ultrapure water. The adsorption mechanism is mainly controlled by electrostatic attractions, and mass transfer processes play a role in the removal of nanoparticles in lake water.

Summary: This study investigated the adsorption of soil organic phosphorus by lanthanum modified biochar, traditional gypsum, and zeolite using phytic acid. The results showed that modified biochar had the strongest affinity for phytate phosphorus and the ability to store phosphorus, fitting well with Langmuir isotherm and pseudo-second-order kinetic equation. Overall, the combination of modified biochar and soil phytate phosphorus can provide a good theoretical basis for reducing the loss of soil organic phosphorus.

Summary: In this study, the adsorption and subsequent desorption of titanium dioxide (nTiO2) and zinc oxide (nZnO) nanoparticles, as well as polyethylene microplastics (MPs), in aquatic media were investigated. The results showed that nZnO had a faster adsorption rate than nTiO2, but nTiO2 had a higher adsorption extent on MPs. The low adsorption of nZnO could be attributed to the partial dissolution of zinc from nZnO, which resulted in soluble zinc complexes not being adsorbed on MPs. The adsorption process was found to be controlled by physisorption for both nTiO2 and nZnO. Meanwhile, the desorption of nTiO2 was low and independent of pH, while the desorption of nZnO was pH-dependent, with a higher desorption rate at a slightly acidic pH. These findings provide insights into the complex interactions and fate of MPs and metal engineered nanoparticles in the aquatic environment.

Summary: High phosphate concentrations in natural waters can lead to eutrophication problems and harm the fauna and flora of ecosystems. This study investigated the adsorption capacity of fruit peel ash from Caryocar coriaceum Wittm in removing phosphate from water solutions. The ash showed high adsorption capacity and followed the Elovich and Langmuir models for kinetics and equilibrium, respectively. The highest removal efficiency was 97.08%. These results suggest that fruit peel ash has potential as a natural bioadsorbent for phosphate removal.

Summary: This paper investigates the effect of PCE on the growth of ettringite through a series of experiments. The results show that PCE adsorption changes the proportion, stability, and morphology of ettringite. During the growth of ettringite crystals, sulfate ions and PCE preferentially adsorb on the faces of rectangular prism, limiting their growth on the {1010} faces and resulting in longitudinal growth.

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.
