Summary: A 90-nm-thick TiO2 grid was fabricated using photolithography, sputtering, and lift-off process. A nanoporous film was deposited on the TiO2 grid, which induced a protrusive structure. Experimental results showed that introducing the TiO2 grid into a dye-sensitized solar cell increased its power conversion efficiency by 25%. This improvement can be attributed to the large surface area and directional electron transport channels of the protrusive structure.

Summary: This study presents the design and fabrication of a photoanode composed of Au/SnS/TiO2 sensitized with natural dye for dye-sensitized solar cells (DSSCs). By calcination, a layer of spherical nano-TiO2 is prepared, and a layer of nano-SnS is deposited on the TiO2 photoanode using the continuous ion layer adsorption reaction (SILAR). The sensitized Au nanoparticles exhibit enhanced localized surface plasmon resonance (LSPR) effects and electron trapping ability, resulting in improved electron mobility and reduced electron recombination in the DSSC.

Summary: Transition metal oxides have shown promise as cathode materials for high-capacity and high-voltage divalent batteries. However, the slow kinetics of divalent cation intercalation into the oxide host remains a major challenge. In this study, spinel-type MgxMn3-xO4 nanocrystals with different Mg/Mn ratios were selectively synthesized and their ability to shuttle Mg2+ ions was investigated. The results suggest that both the size of the nanocrystals and the Mg/Mn ratios play a role in the observed behavior.

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.
