Summary: In this study, titanium dioxide scaffolds were successfully synthesized using the sol-gel method. The scaffolds were formed by using titanium isopropoxide as a precursor and a polymeric network of galactopyranose as a template. The synthesized scaffolds have diameters of 50 nm and porosity ranging from 0.3 to 10 nm. XRD analysis confirmed the formation of crystalline phases in the TiO2 scaffold at 700 degrees C. The use of biological polymers as templates provides a low-cost and efficient approach for the synthesis of new materials.

Summary: By varying the graphene oxide (GO) content, the modification of UV photo-response characteristics in transparent titanium dioxide-graphene oxide (TiO2-GO) nanocomposite thin films was studied. The presence of GO improves the optical band gap of TiO2 without affecting its transparency. The fabricated metal-semiconductor (MS) Schottky junctions with TiO2-GO nanocomposite thin films show rectifying behavior and improved UV response characteristics.

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.
