Summary: In this study, the antibacterial properties of bioreduced graphene oxide (B-rGO) were compared to that of commercial reduced graphene oxide (C-rGO). B-rGO demonstrated good antibacterial activity as confirmed by Scanning Electron Microscopy (SEM). Fourier transform infrared spectroscopy (FTIR) analysis confirmed the presence of numerous oxygen-containing functional groups on the surface of B-rGO. Microcalorimetry and flow cytometry analysis showed that the antibacterial activity of B-rGO was inferior to that of C-rGO.

Summary: Graphene nanomaterials have been commercialized and disseminated into surface waters, but their photodegradation in natural aquatic environments is minimal and slow. This study evaluated the photodegradation of graphene oxide and partially reduced graphene oxide in Columbia River Water, finding that both direct and indirect photolysis occur simultaneously. However, the concentrations of photosensitizers in surface water are not sufficient to initiate degradation of graphene oxide. Overall, graphene nanomaterials show minimal phototransformation in natural surface water.

Summary: Cu(2-)x SbxTe (0 <= X >= 0.2) samples were prepared using the ball milling method. XRD analysis confirmed the presence of Cu2Te phase in pristine and Cu1.95Sb0.05Te samples, while a secondary phase of Sb2Te3 was observed in other samples along with Cu2Te. SEM and TEM analysis revealed the spherical morphology of the samples. Resistivity (p) of Cu-2-xSbxTe decreased with increasing Sb content up to 0.1 and slightly increased for the sample with X = 0.2. The Seebeck coefficient (S) of Cu-2-xSbxTe decreased with increasing Sb content up to 0.1 and then increased for samples with x = 0.2. Cu1.8Sb0.2Te exhibited a high power factor (682 mu W K(-2)m(-1) @ 623 K), resulting in high S and low p values. The achieved zT value of 0.248 for Cu1.8Sb0.2Te at 623 K was relatively higher than reported values for similar materials.

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.
