Summary: Self-supported nanocolumnar Pt:Ni thin films were produced with varying Pt:Ni atomic ratios and mass loadings, showing excellent electrocatalytic activity for the oxygen reduction reaction in polymer electrolyte membrane fuel cells. The electrochemically active surface area was found to be between 22-42 m(2) g(-1), with higher catalytic activity observed as the Pt mass loading increased. Specifically, the Pt:Ni thin film with a 1:3 ratio exhibited the highest specific and mass activity among all tested ratios, outperforming traditional Pt nanoparticles and nanorods.

Summary: Nanocomposite films show promise for multifunctional devices by integrating different functionalities within a single film. The microstructure of the precipitate/secondary phase plays a crucial role in determining the properties of composites. However, there has been limited study on quantitatively characterizing the interphase strain between different phases. In this study, a PbTiO3(PTO)/PbO composite system was prepared in nano-spherical and nanocolumnar configurations. The nanocolumnar structure exhibited a much larger and more uniform strained region in PTO, resulting in enhanced ferroelectric properties.

Summary: The formation of monoclinic VO2 crystal domains at low temperatures in nanocolumnar vanadium/oxygen thin films deposited via magnetron sputtering is analyzed. The synthesis involved depositing amorphous nanocolumnar VO1.9 thin films at room temperature and annealing them at temperatures between 250 - 330 ? in an oxygen atmosphere. The nanocolumnar structures exhibited a thermochromic transition at 47 ? (for annealing at 270 ?) and 58 ? (for annealing at 280 and 290 ?), resulting in a significant drop in optical transmittance in the infrared region.

Summary: This study presents a novel approach for characterizing the optical properties of inhomogeneous thin films, focusing on samples with absorption. Conventional methods of measuring the samples only from the film side can lead to unreliable results. To address this issue, depositing the thin films onto non-absorbing substrates to enable measurements from both sides of the sample is proposed. The results show excellent agreement between the fits and the measured data, providing validation of the overall characterization procedure and offering a more reliable method for optically characterizing inhomogeneous thin films.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.
