Summary: In this study, graphene nanosheets were incorporated into a Cu3SbSe4 matrix to prepare graphene/Cu3SbSe4 composites. The graphene was uniformly distributed in the matrix and led to significantly increased electrical conductivity, decreased Seebeck coefficient, and effectively depressed thermal conductivity. The maximum thermoelectric dimensionless figure of merit reached 0.75 for the composite at 650 K, which was 3.85 times higher than that of pure Cu3SbSe4.

Summary: This work introduces a strategy for significantly enhancing the thermoelectric performance of oxygen-functionalized graphene nanoribbons (GNRs) by reducing thermal conductance and slightly decreasing power factor. The thermoelectric parameters of ether-functionalized GNRs (GPOV) are relatively decoupled, leading to a sharp increase in their ZT value. The application potential of oxygen-functionalized GNRs in thermoelectric materials is revealed, and the broad prospects of the present strategy in the field of thermoelectrics are demonstrated.

Summary: This study reports the first experimental demonstration of incorporating the new generation 2D material, MXene, into rare-earth-free oxide perovskite and its effect on thermoelectric performance. The addition of MXene improves the electron mobility and delocalization, resulting in a significant increase in electrical conductivity and power factor. The MXene also leads to lower lattice thermal conductivity through anharmonicity, resulting in a 700% enhancement in the figure of merit (ZT). Furthermore, a thermoelectric generator prototype using only n-type STN + MXene achieves a higher power output than previous oxide thermoelectric generators.

Summary: Edge termination is crucial for determining the properties of 2D materials. Ab initio simulations reveal a lowest-energy U-edge [ZZ(U)] reconstruction in bilayer phosphorene, reducing edge energy significantly and potentially dominating. Although ZZ(U) changes the topology of phosphorene nanoribbons, it is difficult to be identified through microscopy images. This edge reconstruction also enhances the thermal conductivity of PNR significantly compared with pristine and Klein edges.

Summary: In this study, dual ruthenium atom-doped germanium clusters (Ru2Gen) were investigated using a comprehensive genetic algorithm and density functional theory (DFT) calculation. It was found that small clusters tend to adopt an exohedral structure with a Ru dimer as the core surrounded by Ge atoms. As cluster size increases, half-encapsulated structures start to form, and clusters with 12 to 15 atoms exhibit a geometry based on a regular pentagonal prism with additional Ge atoms. Certain clusters were found to have high structural and chemical stability, and possess a magnetic moment, which is different from the reported non-magnetism of monatomic doping.

Summary: By using high-throughput first-principles calculations, this study explores 2D ternary compounds of a transition metal (X = Fe, Mn, Cr), Ge, and Te, and identifies ferromagnetic and antiferromagnetic XGT monolayer structures with practical magnetic transition temperatures. The coupling strength of ferromagnetism in XGT monolayers is related to the ratio of the transition metal element, while the band gap opening is affected by the occupancy of transition metal d states and the Te content. This work provides a unique perspective for designing compound functional materials and enriches the family of 2D magnets for technological applications.

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.
