Summary: A new multicationic structurally disordered K5FeHf(MoO4)(6) crystal belonging to the molybdate family is synthesized and its electronic and vibrational properties are characterized. The vibrational spectra are dominated by the MoO4 tetrahedra vibrations, while the lattice modes are observed in a low-wavenumber part of the spectra. The compound exhibits paramagnetic behavior with dominant antiferromagnetic interactions and has direct and indirect optical bandgaps of 2.97 and 3.21 eV, respectively. The narrowing of the bandgap is explained by the presence of Mott-Hubbard optical excitation in the system of Fe3+ ions.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
