Summary: The precise deposition of nanoscaled structures is crucial for nanomaterial applications. This study successfully fabricated clean and well-defined Ru nanomaterials using highly focused electron beam-induced deposition. The study found that the deposition process competed with the electron-induced etching, resulting in lower Ru content initially. However, with increasing electron doses, the Ru content increased and the etching process became less pronounced. This research expands the possibilities of engineering nanostructured materials.

Summary: Dissociative electron attachment (DEA) plays an important role in increasing the efficiency of radiosensitizers used in chemoradiation therapy. This study investigates how rearrangement reactions and orbital structure modification can enhance DEA in pentafluorothiophenol (PFTP) and 2-fluorothiophenol (2-FTP). The results show that perfluorination of the aromatic ring in these compounds promotes HF formation by lowering the threshold for DEA and influencing the orbital structure, providing a potential path for designing new and efficient radiosensitizers.

Summary: Solution phase photochemical experiments showed that (eta 4-diene)-Ru(CO)3 complexes can be used as precursors for photoassisted chemical vapor deposition of ruthenium by losing both diene and CO ligands. The quantum yields of ligand loss were found to depend on the structure of the diene, and subsequent ligand loss was determined to occur from secondary photolysis. The compounds exhibited little luminescence, indicating that radiative decay of the excited states was not competitive with photochemical ligand loss. Additionally, the formation of colloidal Ru species was observed after irradiation in hydrocarbon solutions in the absence of phosphite.

Summary: Comparisons were made between aerosol-assisted chemical vapor deposition of MoS2 films from solutions containing single-source precursors and coreactant solution, indicating the significance of ligand precoordination on film properties. Raman spectra and GI-XRD patterns showed that the single-source precursors resulted in more intense and sharper signals for 2H-MoS2, suggesting improved crystallinity. SEM and XPS analysis were also conducted to evaluate morphology and composition. Thermolysis of the single-source precursors indicated the generation of a terminal sulfido on the molybdenum center with loss of a heteroatom stabilized carbene.

Summary: The synthesis, characterization, and thermogravimetric analysis of tris(N,N'-di-isopropylacetamidinate)molybdenum(III) (Mo(iPr-AMD)(3)) are reported. Mo(iPr-AMD)(3) is a rare example of a homoleptic mononuclear complex of molybdenum(III) and fills a longstanding gap in the literature of transition metal(III) trisamidinate complexes. Thermogravimetric analysis reveals excellent volatilization at elevated temperatures, indicating potential applications as a precursor for vapor phase deposition of Mo-based materials. The potential of Mo(iPr-AMD)(3) as a stable, high-temperature precursor for both chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes is demonstrated. Overall, a rating of 8 out of 10 is given to this article.

Summary: In this study, Tetrakis(dithiocarboxylato)molybdenum(iv) complexes were synthesized and characterized as precursors for the aerosol assisted chemical vapor deposition (AACVD) of MoS2 thin films. The thermal behavior of the complexes was suitable for AACVD, and MoS2 thin films were successfully grown using Mo(S2CMe)(4) as a precursor in toluene solution. The films exhibited a 2H-MoS2 structure with vertically oriented morphology and a thickness of 2.54 μm, which was confirmed by various characterization techniques including GIXRD, XPS, EDS, and FE-SEM. The Raman E-2g(1) and A(1g) vibrational modes of crystalline 2H-MoS2 were also observed.

Summary: Motivated by the potential use in Focused Electron Beam Induced Deposition (FEBID), the reactivity of tetrakis(dimethylamino)silane (TKDMAS) towards low energy electrons and the composition of its deposits were studied. Significant fragmentation was observed in dissociative ionization (DI), with hydrogen transfer reactions and new bond formations playing a significant role. However, the nitrogen content in the deposits was surprisingly lower than expected. A post treatment protocol using water vapor was developed to remove unwanted carbon content in FEBIDs created from TKDMAS.

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.

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.
