Summary: Iron oxide phase transformations can be influenced by trace metals such as zinc, affecting the speciation of these metals in soils and sediments. This study investigates the phase transformations of zinc-containing ferrihydrite in the presence of different concentrations of Fe(II). The results show that the presence of zinc accelerates the phase transformations and leads to the formation of different iron oxide phases. The retention of zinc in the newly formed phases suggests that trace metal micronutrients and contaminants may not be mobilized under circumneutral conditions despite the formation of more crystalline iron oxides. These findings have implications for understanding the behavior of trace metals in low temperature environments.

Summary: In this study, new transition metal complexes with different structures were successfully designed, synthesized, and characterized. The structures of the complexes were determined using various spectroscopic and analytical techniques, and their properties were further analyzed using theoretical calculations. Furthermore, the complexes exhibited significant anti-inflammatory activity, indicating their potential as promising candidates for anti-inflammatory drugs.

Summary: This study demonstrates that enzymatic hydrolysis can significantly enhance the bioaccessibility of iron in pea protein concentrates, while fermentation has less effect. Phytase treatment and combined phytase and protease hydrolysis significantly improve the bioaccessibility of iron, but do not have a significant promotive effect on zinc bioaccessibility.

Summary: This study prepared an analogous complex and obtained a series of crystalline polymorphs with different packing modes and intermolecular interactions. By comparing different ligands, it was found that the NCSe- ligand showed a stronger ligand-field strength and weaker cooperativity compared to NCS-, resulting in a critical shift of T-1/2 values and a more gradual transition process.

Summary: This study synthesized novel rice husk-based adsorbents activated by potassium hydroxide and applied them to remove hazardous heavy metal ions from synthetic wastewater. The results showed that both the KOH-RHH and AgNP-KOH-RH adsorbents had high adsorption capacity and color removal efficiency, which are significant for industrial wastewater treatment and adsorption mechanism research.

Summary: In this study, the authors investigated the influence of complex cations on the structure formation, crystal packing, antimicrobial activity, and enzyme activation of isostructural complexes. They found that despite the similarity in composition and structure, the complexes exhibited different levels of antimicrobial activity. The authors also discovered a correlation between the thermodynamic stability of cations and their antimicrobial activity. Additionally, quantum chemical calculations provided insights into the cations-cell membranes interactions and revealed that compounds with specific cations exhibited higher lipophilicity and bioactivity. Furthermore, the study explored the influence of the complexes on the activity of alpha-L-rhamnosidases and identified factors such as the presence of water molecules, hydrogen bond networks, and the formation of active intermediate complex enzyme-effector-substrate that contributed to the activation properties of certain compounds.

Summary: The current study demonstrates that the Schiff base HL can function as a selective chemosensor for Zn(ii) and Ni(ii) in purely aqueous and semi-aqueous media. The chemosensor exhibits a color change response to the presence of Zn(ii) and Ni(ii) under UV light. Two mononuclear crystalline compounds have been developed as a result of the reaction between HL and Zn(ii)/Ni(ii), and they show promising fluorescence properties. Additionally, complex 2 has shown the ability to detect ATP in a fully aqueous solution.

Summary: This study investigates the oxidation of mononuclear Fe(ii) centers in the metal-organic framework MOF-74 in the presence of various reactive species. The effect of reaction entropies on the Fe(ii) oxidation barriers is examined, revealing different entropic contributions for different species. The role of entropic effects on the mechanisms and energetics of the reactions is discussed.

Summary: The interactions between two peptide ligands derived from the cytoplasmic C-terminal region of Escherichia coli FeoB protein and Fe(II), Mn(II), and Zn(II) ions were investigated. The study revealed the crucial role of the Feo system in bacterial Fe(II) acquisition and the mechanism of metal ion trafficking in the complex intracellular environment. The specificity and metal-binding modes of the C-terminal region of E. coli FeoB protein were explored.
