Summary: In the marine environment, Na+ ions are a significant factor causing marine corrosion due to their high content. However, in this study, it was found that MgCl2 solution induced more severe iron corrosion compared to NaCl solution, despite its lower concentration. This is believed to be because Mg2+ ions outperform Na+ ions in metal gas phase corrosion. Additionally, ethanol, which is commonly regarded as a corrosion inhibitor, unexpectedly aggravated iron corrosion in the gas phase and at the gas-liquid interface, particularly in the presence of Mg2+ ions.

Summary: We have developed a colloidal synthesis method for bismuth chalcohalide nanocrystals with a hexagonal phase. The structure of these nanocrystals can be described by the Bi13S18X2 (where X = Br and I) model. It was found that the presence of Bi24+ dimers, formed by columns of Bi atoms, and Peierls-type distortions are responsible for the anomalously low band gap and intervalence charge transfer in this material. Our findings and synthetic approach provide fundamental understanding for the use of hexagonal bismuth chalcohalides in diverse applications such as photocatalysis and thermoelectrics.

Summary: This paper presents the latest studies on iron-based fluorides, discussing their compositions and orders/disorders using Fe-57 Mossbauer spectrometry. A new ammonium hexafluoride compound, (NH4)Cu2+Fe3+F6, was synthesized and its disordered cubic pyrochlore structure was established using powder XRD. Mossbauer spectrometry confirmed the cationic disorder and magnetic frustration in Fe3+, and the hydration of (NH4)CuFeF6 resulted in the formation of a rare new structure, (NH4)CuFeF6(H2O)4(H2O)-H-, with millimeter-sized single crystals.

Summary: Rates and mechanisms of important reactions in the cycling of electrons via the geochemical transformations of iron have been identified using Mossbauer spectrometry. The cycling of iron through various reservoirs depends on high surface-area-to-volume ratios of Fe-bearing solids. Fe-bearing solids surfaces can interact chemically with reductants and oxidants, facilitating electron transfer as well as dissolution and precipitation.

Summary: This article presents a solvothermal-based method for preparing gram-scale ferrite nanoparticles with well-defined shapes (such as nanocubes and nanostars) and fine control of structural and magnetic properties. The shape of the nanoparticles can be controlled by adjusting the aldehyde ligand used. Cubic ferrite nanoparticles can be obtained using benzaldehyde and its derivatives, while aliphatic aldehydes result in spherical nanoparticles. By replacing the primary amine with a secondary or tertiary amine, star-like nanoparticles can be obtained. The precise control over shape, size distribution, composition, and crystallinity ensures the preparation of gram-scale nanocubes/star-like nanoparticles with specific adsorption rates comparable to or better than those prepared by thermal decomposition methods. This method can be completed in approximately 10 hours with an average level of expertise in chemistry.

Summary: The reactivity of Fe(II) sorbed on different types of clay towards U(VI) reduction was investigated. U(VI) reduction only occurred on Fe-free synthetic montmorillonite (MONT), and a hydrated uranyl silicate (soddyite)-like phase was formed. The lack of reactivity on Fe-poor natural montmorillonite (Fe-MONT) and Fe-rich natural nontronite (NAu-2) is likely due to inter-valence charge transfer (IVCT) between surface Fe(II) and structural Fe(III). This study highlights the dependence of clay sorbed Fe2+ reactivity on the nature of clay and the oxidation state of sorbed Fe.

Summary: The sol-gel process was used to synthesize ferrite Ni0.3Zn0.7Cr2-xFexO4 nanoparticles, which were then calcined at various temperatures. The structure and magnetic properties of the nanoparticles were characterized by XRD, SEM, VSM, and Mossbauer spectrometry. The results showed that the nanoparticles had a single-phase spinel structure and low magnetization due to the absence of ferromagnetic Ni2+ ions and weak interactions between Fe3+ ions.

Summary: Magnetite can effectively remove contaminants from wastewater, especially arsenic, antimony, and uranium present in the acidic phospho-gypsum leachates derived from the phosphate fertilizer industry. However, the presence of phosphate limits the removal of antimony and arsenic by magnetite. Therefore, a three-step design involving oxidation, precipitation, and reaction with magnetite can achieve high contaminant uptake in field applications.

Summary: In this paper, classical molecular dynamics (MD) simulations were employed to investigate the locations, binding modes and mobilities of carboxylate ligands on the different facets of CdSe nanocrystals. The results suggest that these features are influenced by the temperature of the system and the coordination number of the surface (Cd and Se) atoms. High ligand mobilities and structural rearrangements are observed with low coordination of Cd atoms, while undercoordinated Se atoms are found to form spontaneously on the nanosecond timescale, potentially playing a role in photoluminescence quenching.

Summary: The use of superparamagnetic iron oxide nanoparticles (SPIONs) in various medical applications has been hindered by their rapid clearance from circulation by the reticuloendothelial system (RES) or mononuclear phagocyte system. This study proposes a strategy to encapsulate SPIONs in red blood cells (RBCs) to enhance their biocompatibility. The research focuses on optimizing the chemical synthesis of magnetic nanoparticles (MNPs) and then encapsulating them in RBCs. After achieving high-quality encapsulation, in vitro experiments were conducted to evaluate the potential of these engineered MNP-RBC constructs in theranostics.
