Summary: The prime goal of today's environmentalists and industrialists is to find appropriate and practical wastewater treatment methods for effective decontamination of wastewater bodies. This study investigates the sunlight driven photocatalytic degradation of rhodamine-B using a hydrothermally synthesized tin oxide-graphene oxide nanocomposite. The physiochemical characterization of the composite was accomplished through various techniques. The nanocomposite exhibited faster degradation performance compared to separate tin oxide and graphene oxide. The synergistic impact of graphene oxide and tin oxide leads to enhanced electron-hole recombination rate and carrier separation, making the nanocomposite an efficient method for real wastewater treatment at an industrial scale.

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.
