Summary: This methodology involves environmentally friendly covalent functionalization of reduced graphene oxide (rGO) nanosheets with arylazo sulfones through visible-light irradiation. It allows various tagged aryl units to be conveniently accommodated on the rGO surface, with mild reaction conditions, absence of photosensitizers, functional group tolerance, and high atomic fractions. Control experiments for mechanistic elucidation (Raman analysis) and chemical nanomanipulation of the tagged rGO surfaces were also conducted.

Summary: Graphene oxide (GO) has attracted significant interest in material science, biomedicine, and biotechnology due to its exceptional physical properties and surface functionalization capacity. In this study, a simple and environmentally friendly method was developed to prepare surface-functionalized GO nanosheets using tannic acid (TA) as a biological macro-molecule. The covalent grafting of TA improved the hydrophobicity and dispersion of GO in organic solvents, while also acting as a crosslinker to enhance thermal stability and antibacterial properties. This research emphasizes the potential of TA for the exfoliation and functionalization of GO, as well as its applications in biomedicine and the development of green nanocomposites.

Summary: Graphene has remarkable physicochemical properties, but its low dispersibility and tendency to aggregate hinder its full exploitation. Graphene oxide (GO) is a promising substitute with high dispersibility and abundant oxygen-containing groups. However, the reactivity of GO and the lack of control in its derivatization pose challenges. This review discusses the chemical reactivity of GO, the obstacles in precise control of its functionalization, and future directions for improving GO chemistry control.

Summary: Hexagonal boron nitride nanosheets (h-BNNS) have shown great potential as 2D nanomaterials. A mechanochemical method using NaOH aqueous solution as a process aid was developed to obtain high-yield h-BN nanosheets. The material prepared by autoclave and ball milling followed by tip sonication at 40 degrees C (h-BNNS-T40) showed the most promising results in terms of yield, quality, and practicality. A hybrid lamellar material prepared by drop-casting and dip-coating techniques showed improved thermal stability and chemical interactions between h-BNNS and graphene oxide (GO).

Summary: Graphene-based nanohybrids show potential for various applications, but challenges such as low solubility and aggregation limit graphene's usefulness. Derivatives like GO and RGO have great properties and can be produced in large quantities. Nanohybrids of GO/RGO with porphyrins have potential in fields like photocatalysis and drug delivery, but questions remain about their structure and interaction. Experimental and theoretical studies on the interaction between GO/RGO and metal-free porphyrins suggest that the nanohybrids are non-emissive due to significant charge-transfer character in excited states. Efficient simulation methods may help in screening properties of new GO/RGO nanohybrids.

Summary: This study explored the correlation between the graphene-based materials and graphene oxide (GO) morphology on the photocatalytic activity for hydrogen production. The research found that the duration of sonication significantly impacts the efficiency of hydrogen production, with moderate sonication enhancing activity while prolonged treatment leading to fragmentation of GO flakes. It was also observed that the photocatalytic system produced the highest amount of H-2 when graphene oxide occurs as monolayers, with efficiency decreasing with smaller GO sheet sizes.

Summary: Hollow MoS2 cubes and spheres were successfully synthesized using a one-step hydrothermal method with the hard template method. The hollow MoS2 cubes exhibited higher specific capacitance and energy density compared to the hollow MoS2 spheres. The symmetrical supercapacitors assembled with these hollow structures showed good performance and high capacity retention after multiple cycles. These findings suggest that controlling the pore structure and surface characteristics of MoS2 is crucial for enhancing its electrochemical properties.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Summary: The stability of La1/3Sr2/3Fe1-xMnxO3-delta, a perovskite-type oxide, under reducing conditions is dependent on the manganese content. Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions. Additionally, the change in the La/Sr ratio affects the concentration of iron and manganese ions.
