Summary: The rise of antibiotic waste in water has become a pressing issue for both human health and the environment. In this study, a sol-gel amalgamation of nanocrystalline La-doped NaTaO3 perovskites modified with Bi2O3 showed promising results in photocatalytic degradation of the emergent antibiotic ciprofloxacin. The close junction of Bi2O3 and NaTaO3 contributed to improved photoinduced charge transfer and energy bandgap suppression, leading to efficient removal of antibiotics through visible-light irradiation.

Summary: The purpose of this study was to investigate the effect of photocatalytic degradation using nitrogen and tungsten co-doped titania (TiO2) nanoparticles, which are cost-effective and environmentally friendly. The synthesized nanoparticles were analyzed using various techniques, including spectroscopy, microscopy, and spectrometry. The co-doping of metal and non-metal enhanced the photocatalytic properties of the TiO2 nanoparticles, particularly in the visible region. This resulted in improved absorption of visible light and reduced recombination of electron-hole pairs, leading to accelerated photodegradation. The bandgap of the titania nanoparticles was reduced after efficient doping, enabling the photodegradation of malachite green under visible light illumination. The results of photocatalytic degradation were confirmed using spectroscopy and high-performance liquid chromatography coupled with mass spectrometry.

Summary: This study focuses on fabricating VO2 films doped with different contents of tungsten (W) element on high-purity Si substrate. The films exhibited good crystallinity and uniform thickness. X-ray diffraction and X-ray photoelectron spectroscopy characterizations showed that W can be doped into the VO2 lattice, resulting in small lattice distortion. In situ FT-IR measurements revealed that the phase transition temperature of the films can be continuously decreased with increasing W doping content. The doping also significantly enhanced the film's conductivity and reduced optical transmittance. These findings provide important insights into designing doped VO2 films for silicon-based devices.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.
