Summary: The characteristics and mechanism of phosphate adsorption onto magnetite, hematite, and goethite were comparatively studied, and it was found that magnetite has a higher adsorption capacity. Additionally, the amendment and capping materials of magnetite, hematite, and goethite can effectively suppress the release of endogenous phosphorus from sediment into the overlying water.

Summary: The characteristics and mechanism of phosphate adsorption onto magnetite, hematite and goethite were studied, and the effects of magnetite, hematite and goethite amendment and capping on endogenous phosphorus (P) liberation from sediment into overlying water (OW) were investigated. The adsorption of phosphate onto magnetite, hematite and goethite followed the inner-sphere complexation mechanism, and the phosphate adsorption capacity decreased in the order of magnetite>goethite>hematite. The magnetite, hematite and goethite amendment can all decrease the risk of endogenous P release into OW, with magnetite being the most effective.

Summary: A surface modification strategy is developed to sequentially deposit ultrathin CoOx overlayer and Ni single atoms on Ti-doped alpha-Fe2O3 nanorods. The collaboration of CoOx overlayer and Ni single atoms improves the photo-electrochemical performance for water splitting, with a photocurrent density over three times that of Ti:Fe2O3. The passivation effect of CoOx overlayer reduces surface carrier recombination, while the catalysis effect of Ni single atoms accelerates water oxidation kinetics.

Summary: A new method for measuring soil goethite/hematite ratios is presented, which utilizes the band position of electron pair transition (EPT) in diffuse reflectance spectra processed by continuum removal. The method is validated and shown to effectively eliminate the matrix effect. Application of the method to loess-paleosol sequences confirms its potential for improving the measurement of goethite/hematite ratios in sediments.

Summary: The study prepares high-quality uniform CdSe nanorods by improving the reactivity of the Se source and using a secondary phosphine along with the conventional tertiary phosphine. Core-shell nanorods with narrow emission bandwidth, high PLQY, and high linear polarization are then synthesized and assembled into long-range-ordered microarrays with programmable patterns. The potential applications of these nanorods in liquid crystal displays and full-color light emitting diodes displays are highlighted.

Summary: The current study investigates the influence of iron minerals on the properties of geopolymer materials. The additions of hematite, magnetite, and goethite remain largely unreacted in the binder, affecting the compressive strength. The presence of voids and cracks in the micrographs of geopolymer materials is related to the gel formation and the interaction between the gel and crystalline additions.

Summary: A multistep synthesis method was used to prepare nanoscale core@shell spherical heterostructures for H2 optical detection. These nanoheterostructures consist of gold cores, silica shells, and a thin layer of spherical palladium nanoparticles. The samples were characterized by transmission electron microscopy, and the three-dimensional core@shell configuration was confirmed by electron tomography. The optical properties of the nanostructures were analyzed, and their potential for H2 detection was evaluated.

Summary: The electrochemical behavior of silver nanoparticles in mesoporous oxide electrodes was investigated. The results showed the importance of Ag+ ion retention by TiO2 films. Two anodic peaks in the voltammetric curves were observed, which could be explained by the presence of two distinct populations of silver nanoparticles with different size distributions in the film.

Summary: The anionic luminescent complex [(ThiaSO(2))(2)(Mn-II)(4)F](-) is introduced between the positive layers of Layered Double Hydroxides in formamide, resulting in the doping of LDH. The photophysical properties of the resulting compound show luminescent properties with high sensitivity to oxygen under different atmospheres and excitation wavelengths. Incorporating the luminescent complex within the LDH host allows for high sensitivity to oxygen without photo-degradation, making it potential for oxygen sensing or singlet oxygen generation applications.
