Summary: This study successfully loaded clam shell powder into TiO2 to improve the photodegradation performance of TiO2 for dye removal. The TiO2/Clam Shell powder composite exhibited lower bandgap energy, larger surface area, and high crystallinity. The optimal ratio of TiO2 to CS was found to be 4:1, resulting in the complete degradation of 10 ppm of methylene blue within 120 minutes.

Summary: A magnetic graphene nanocomposite (Fe3O4/G) was successfully synthesized and characterized for methylene blue dye removal, showing excellent adsorption efficiency. The nanocomposite exhibited fast magnetic separation due to the magnetic properties of the magnetite nanoparticles, achieving 100% removal efficiency for MB dye. The adsorption behavior followed a pseudo-second-order kinetic model, with equilibrium reached after 15 minutes, and the equilibrium data fit well with Langmuir and Freundlich isotherm models.

Summary: TiO2/MXene composites were synthesized and showed enhanced removal efficiency for methylene blue (MB) dye. The removal rate of MB by TiO2/MXene composite materials was 96.44% under ultraviolet light, 29.83% higher than pure TiO2. Under visible light, the removal rate of MB was 8.26 times higher (40.19%) than pure TiO2. This enhancement was attributed to improved charge antirecombination and high adsorption capability toward MB.

Summary: This study presents the visible-light photocatalytic performance of 3-aminopropyltriethoxysilane (APTES)-modified TiO2 nanomaterials obtained by solvothermal modification and calcination. The APTES/TiO2 photocatalysts exhibit higher pore volume and specific surface area, and the adsorption process negatively affects the photocatalytic properties. The highest dye decomposition degree is observed for nanomaterials calcined at 900 degrees C with optimal APTES concentration of 500 mM.

Summary: This paper presents a modification of titanium dioxide with fumed silica and investigates the characteristics and photocatalytic activity of the materials. The results show that the presence of SiO2 effectively inhibits the increase in crystallite size and decrease in specific surface area during calcination. SiO2 also contributes to the increase in specific surface area and the change in band gap energy values. The photocatalytic activity of SiO2/TiO2 photocatalysts is higher compared to the starting TiO2, and it increases with the increase in SiO2 content.

Summary: Metal oxide nanoparticles, such as zinc oxide, have unique properties at the nanoscale and have been extensively studied for various applications. Plant-mediated synthesis of zinc oxide nanoparticles offers a green and scalable alternative to conventional methods. However, the use of indigenous medicinal plants in southern Africa for the synthesis of zinc oxide nanoparticles is underexplored.

Summary: A bibliometric analysis was conducted to study publications on biodiesel-fuelled engine performance research. Data from 1993 to 2021 were collected using the Scopus database. Network analyses were performed to examine journal and paper citations, co-authorship, and author keyword co-occurrences. The study identified a total of 2454 scientific articles published on the topic, with an increasing trend over time. India was the most productive country, and the University of Malaya was the most productive institution. The research focused on biodiesel additives, combustion and performance improvement, and emission reduction strategies.
