Summary: The efficient removal of ammonium cation, one of the main causes of water source eutrophication, has been achieved using amorphous aluminosilicates as low-cost ion exchangers. The materials with varying Si/Al ratios were prepared by coprecipitation and showed higher cation exchange capacity than other zeolites. The ammonium uptake was investigated under different conditions and the amorphous aluminosilicate with Si/Al = 3 showed promising performance for ammonium removal.

Summary: The synthesis and characterization of six new heterometallic UO22+/Pb2+ compounds with rare M-oxo interactions were reported. The spectral effects of these interactions were measured using luminescence and Raman spectroscopy. Computational methods indicated that the interactions are mainly through charge transfer between cationic units, with energy values varying depending on the distance and angle of interaction. Strong interactions with Pb-oxo were found to weaken U=O bonds and led to luminescence quenching and red-shifting of the uranyl Raman stretch.

Summary: Multifunctional electrodes for structural supercapacitors were prepared by infiltrating single-walled carbon nanotubes (SWCNTs) into woven carbon fibers (CFs) using a vacuum method. The use of reductive charging chemistry ensured a high degree of individualization. The resulting electrodes showed high conductivity, surface area, and electrochemical performance, and significantly improved the electrical conductivity, surface area, and in-plane shear properties of the CF fabrics. Structural supercapacitors based on these electrodes exhibited high specific energy and power densities in the chosen electrolyte. This approach provides a new route to structural energy storage systems.

Summary: Hybrid ion exchangers (HIXs) with fine Cu2O and Cu-0 particles were analyzed thermally to determine their hygroscopic water content and the effect of the copper atom's oxidation state in the deposit on thermal properties. The study found that Cu-0 was more water repellent than Cu2O, and the oxidation state of the copper atom influenced the amount of forming char in the composite materials. Additionally, under different atmospheres, the particles transformed into different phases, indicating the inorganic phase's participation in char formation and transformation during pyrolysis.

Summary: The synthesis of copper compounds with polymeric adsorbents showed that Cu2O and CuO significantly reduced the porosity of the obtained composites. Samples dried thermally lost porosity and increased bulk density, while freeze-dried samples retained typical macroporous characteristics. This reduction in porosity was mainly caused by the surface morphology and agglomeration tendency of Cu2O and CuO particles.

Summary: The study demonstrates the modification of anion exchangers to obtain a reactive organic polymer containing dispersed CuxS. The distribution of cuprite or tenorite within the polymeric matrix and the porous structure of the anion exchanger determine the content of CuxS. The sulphidation process converts Cu2O into CuS more efficiently and selectively compared to CuO, and the morphology of the resulting covellite particles is influenced by the porous structure of the anion exchanger.

The host materials alone exhibited an affinity to anionic water contaminants and antimicrobial properties. The addition of various copper compounds enhanced these properties and demonstrated new properties. The unconventional synthesis methods resulted in the creation of a new group of hybrid ion exchangers containing copper.

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.
