Summary: This paper presents an electrochemical exfoliation method for producing graphene oxide and characterizes it using electrochemical techniques. The electrochemical behavior of the produced graphene oxide was studied through cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Additionally, various characterization techniques such as X ray Photoelectronic Spectroscopy (XPS), Raman spectroscopy, Transmission Electron Microscopy (TEM), and Atomic Force Microscopy (AFM) were employed to analyze the structural and chemical properties of the exfoliated graphene oxide. The results demonstrate that the electrochemical exfoliation method allows for the production of graphene oxide materials with varying degrees of oxidation, defect density, and crystallite size.

Summary: The WS2 monolayer has been shown to be an excellent template for low-temperature (400°C) epitaxy of AlN. Thin films of AlN grown at low temperatures exhibit higher crystalline quality compared to films grown directly on sapphire substrates. The small lattice mismatch between AlN and WS2 monolayer, along with a proposed growth mechanism, explain the excellent van der Waal epitaxy observed. This research highlights the potential of transition metal dichalcogenides (TMDCs) as buffer layers for III-nitride deposition and suggests a novel combination of AlN and TMDCs for future 2D field-effect transistor research due to the extremely low leakage current of high-quality AlN films.

Summary: Conventional exfoliation methods are limited to layered host crystals with specific compositions, while a novel approach utilizing ordered vacancies allows for the exfoliation of previously unattainable 2D crystal structures. Pyrrhotite crystals with complex vacancy superstructures were synthesized and electrochemical intercalation and delamination produced ultrathin 2D flakes with sub-unit cell thicknesses. The controlled morphology of these materials below the monolayer limit has significant effects on their magnetic properties, showing potential for future applications in electronics and spintronics.

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.

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.
