Summary: In addition to their common applications as catalysts, drug delivery systems, and sensors, metal oxides can also function as adsorbents in wastewater treatment. Chemical modification is often necessary to optimize their adsorption capabilities, leading to the production of carbonaceous metal oxides, polymeric metal oxides, and surfactant-supported metal oxides. Creating tailored morphologies, high surface areas, and specific affinity for adsorption are the main driving factors behind the development of such materials. Various analytical techniques have been used to investigate the mechanisms underlying these reactions. The development of chemically modified metal oxides with supported surfaces is of particular importance due to their increased practical applications.

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.
