Summary: A simple approach for degrading organic pollutants based on copper doped sodium bismuthate (CSB) was proposed, allowing for continuous generation of reactive oxygen species without the need for irradiation or other chemicals. The reaction proceeds through two mechanisms, direct oxidation involving singlet oxygen and catalytic oxidation primarily yielding superoxide radical, providing insights into the oxidative activity of CSB for water treatment.

Summary: Three-dimensional difference pair distribution functions (3D-Delta PDFs) from X-ray and neutron diffraction experiments were used to analyze yttria-stabilized zirconia (Zr0.82Y0.18O1.91). The results show that oxygen ions neighboring a vacancy shift towards the vacancy, while metal ions shift away from the vacancy. The neutron 3D-Delta PDF reveals a tendency for vacancies to cluster, leading to sixfold coordinated metal ions.

Summary: This study investigates the oxidative transformation of 2-phenylethanol using Ce(IV) as the oxidant in pure aqueous and surfactant medium. A comprehensive kinetic analysis predicts the mechanism of transformation and monitors the progress of the reaction through absorbance measurements. The results indicate a first order dependence of rate on oxidant concentration in pure aqueous medium, while the presence of surfactant leads to complex formation and dependence on acidity. Temperature effects were also studied, and a suitable kinetic model is proposed for both aqueous and surfactant medium oxidation reactions.

Summary: Neutron total scattering and multi-edge X-ray absorption analyses were performed on a powder sample consisting of 0.5Ba(Zr0.2Ti0.8)O-3-0.5(Ba0.7Ca0.3)TiO3. The results showed distorted titanium in a BaTiO3-like chemical and bonding environment, and cubic symmetry for zirconium in ZrO6 octahedra. Combining different phases models were needed to better describe the local structure.

Summary: This study focused on the synthesis and characterization of different materials for Cs sorption, showing that amorphous analogues are better Cs sorbents compared to crystalline ones. Additionally, it was found that crystalline a-Hf phosphate has better Cs sorption capacity than crystalline a-Zr phosphate, attributed to the lower solubility of Hf phosphate preventing 'defect healing' during the synthesis process.

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.
