Summary: A well-characterized barite powder was studied using base titrations to investigate the effects of pH, ionic strength, temperature, and the presence of added calcium ions. Zeta-potential measurements were also conducted. The results were integrated into a surface complexation model, which showed that proton uptake/release was much lower than for typical metal oxides, but zeta-potentials were similar. Differences in H+ uptake/release under different conditions could not be confidently attributed to experimental error or model uncertainties.

Summary: In this study, a range of experimental techniques and modeling simulations were used to analyze the adsorption and separation behavior of Cs+ on TiO2 nanotubes for water decontamination. The presence of CO2 as a contaminant was considered in both experiments and models. The results showed that H+ ions were the main charge-determining species, while Cs+ ions were mainly in the diffuse layer on the outer surface with significant contribution only at high concentrations and high pH. The effect of nanotube size on adsorption behavior was found to be minimal, except for very thick nanotube layers (1 to 2 nm). Molecular dynamics simulations revealed the importance of cation size and careful definition of adsorption sites for Cs+ adsorption.

Summary: The study investigates the difference spectra of cationic, anionic, and nonionic surfactants adsorbing onto cement particles using ATR-FTIR spectroscopy. Specific features appear at -2920 and -2850 cm-1, indicating the formation of an ordered or disordered structure on the surfactant alkyl tail. The results suggest that the heterogeneously charged mosaic surface of the cement particle consists of negatively charged isolated parts and positively charged continuous parts, arising from the distribution of hydrate phases with different electrical properties.

Summary: Recently, the development of antimicrobial materials has been a focus of attention. Incorporating copper nanoparticles (NpCu) into a chitosan matrix is a viable strategy to prevent their oxidation. The nanocomposite films (CHCu) showed improved tensile strength, decreased elongation at break, lower solubility, and reduced swelling compared to chitosan films (control). These nanocomposites also exhibited excellent antibacterial capacity against both Gram-negative and Gram-positive bacteria, and the antibacterial mechanism involved the interaction of chitosan with bacterial membranes and the diffusion of NpCu into the cells. These materials have potential applications in various fields including biology, medicine, and food packaging.

Summary: This study presents a community data-driven surface complexation modelling framework, which can simulate potentiometric titration of mineral surfaces. By fitting compiled community data, representative protolysis constants can be obtained, which can reproduce potentiometric titration data from literature sources. This framework allows for the evaluation of different surface complexation model types and surface site density (SSD) on the quality of fit and protolysis constants. It provides a method to reconcile community data and produce mineral protolysis constants for robust surface complexation models in metal sorption and reactive transport modelling.

Summary: In this study, the adsorption of molybdate to hematite was characterized using adsorption isotherms, PHREEQC geochemical modeling, Attenuated Total Reflection-Fourier Transform Infrared Spectroscopy (ATR-FTIR), and X-ray Absorption Spectroscopy (XAS). The results showed that both pH and Mo concentration are important factors in the formation of mono- and polymolybdate species, with low pH and high Mo(VI) concentration contributing to the formation of a polymolybdate surface species on hematite. XAS analysis also revealed the presence of octahedrally coordinated Mo(VI) adsorption species on hematite, providing important insights into the mobility and transport of Mo as a contaminant in the environment.

Summary: The study reveals that a nanoparticulate (NpO2)-O-IV solid is the only speciation of Np sorbed on both doped and undoped magnetites. The Mn-O sites preferentially sorb Np(V) compared to Fe-O sites, indicating the significant role of impurity atom interacting with sorbing species through redox process. The participation of Mn through Fe(II)/Mn (III) redox couple in reducing sorbed Np(V) becomes significant only when the doped-magnetite contains a critical minimum concentration of Mn (>6 wt%).

Summary: The adsorption of cetyltrimethylammonium bromide on sapphire surfaces was studied, and the evolution of interfacial potentials and changes in spectroscopy were analyzed. The results suggest that CTA+ cations can neutralize the negative surface charge and even overcompensate it. The decrease in SFG and SHG intensities can be explained by the adsorbed CTA+ cations disrupting the structural order and replacing some interfacial water molecules.

Summary: In this study, the growth behavior of redox sensitive Fe0 nanoparticles (nZVI) was found to vary on different clay surfaces. The non-swelling kaolinite (K-nZVI) showed dominant surface growth characteristics, forming larger nZVI particles (>24.8 +/- 7.4 nm) with positive zeta potential. On the other hand, the swelling bentonite (B-nZVI) exhibited negative zeta potential, mainly due to the surface charge of bentonite clay. This surface-dependent variation resulted in higher and faster removal of oxy-anions with K-nZVI, while B-nZVI showed higher sorption of cations. XPS and pXRD analysis confirmed the major removal mechanisms of reductive sorption, co-precipitation/complexation, electrostatic attraction, and complexation. The findings highlight the potential applications of K-nZVI and B-nZVI in removing specific contaminants from different types of water sources.

Summary: The chemical transformations of native oxide on stainless steel 309 S prior to pitting in anoxic near saturated geological Q3-brine were studied using synchrotron radiation photoelectron spectroscopy (SRPES). A Cr-rich hydrated mixed iron-chromium oxide, exhibiting n-type semiconducting behavior, is formed after wet polishing. Surface accumulation of holes in the metastable pitting potential region leads to hydroxylation of oxide bonds and subsequent selective dissolution of iron. The open structure of remaining surface chromium hydroxide facilitates the inward access of chloride and water. The inhibiting effect of sulfate is attributed to the formation of stabilizing O-S-O bridges blocking chloride access.

Summary: The stainless steel AISI 309 S, used for containers of vitrified high-level radioactive waste, was subjected to 90 degrees C under highly saline and anoxic conditions for different exposure times up to 294 days. The surface damage was minimal, and no pitting was observed. The corrosion layer consisted of an inner layer comprising mostly chromium (hydr)oxides and an outer layer composed of Fe- and Ni-based spinel compounds with admixed nickel (hydr)oxides. Minor amounts of magnetite and layered double hydroxide were also identified. Dissolved metal ion concentrations were very low, with only a slight increase in pH and limited decrease in redox potential.

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 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.
