Anomalous Temperature-Induced Particle Size Reduction in Manganese Oxide Nanoparticles.

The intricate role of temperature in the structure-property relationship of manganese oxide nanoparticles (MnO NPs) remains an open question. In this study, we successfully synthesized MnO NPs using the hydrothermal method with two differing temperatures, namely, 90 and 150 °C. Interestingly, a smaller average particle size is found when MnO NPs are synthesized at 150 °C compared to 90 °C, corresponding to 46.

Synthesis of Electrospun PAN/TiO/Ag Nanofibers Membrane As Potential Air Filtration Media with Photocatalytic Activity.

The PAN/TiO/Ag nanofibers membrane for air filtration media was successfully synthesized with electrospinning method. The morphology, size, and element percentage of the nanofiber were characterized by a scanning electron microscopy-energy dispersive spectroscopy, while X-ray fluorescence and FTIR were used to observe the chemical composition. The water contact angle and UV-vis absorption were measured for physical properties.
