Summary: In this study, a copper oxide thin film was prepared using the CW laser assisted-chemical bath deposition (LACBD) technique. The effect of laser wavelength on the structural, optical, and electrical properties of CuO film was investigated. Increasing the laser wavelength resulted in decreasing the grain size of the film and enhancing the crystallization. The p-CuO/n-Si heterojunction photodetectors exhibited two peaks of response at 450 nm and 800 nm.

Summary: Aerosol deposition is a ceramic coating process that enables films to be fabricated by microparticle impact at room temperature. In this study, the optical emission during AD was measured and found to be proportional to the flux of the kinetic energy of the aerosol particles, suggesting that the emission occurred via fracto-emission during particle impact. The gas temperature remained low at around 300 K, confirming that AD is a room-temperature process.

Summary: In this study, we investigated the reddish coloration of a CH3OH/H2O ice irradiated by cryoplasma. The production rates of the reddish materials decreased with increasing temperature. Our kinetic analysis revealed that the disappearance of the materials under cryoplasma irradiation showed a positive temperature dependence. These results suggest that radiation-driven chemistry and thermally-driven chemistry together influence the formation and stability of reddish materials.

Summary: Atmospheric-pressure nonequilibrium plasma processing using microdroplets has garnered attention in recent years. Understanding the evaporation behavior of droplets in plasma is crucial for improving process controllability. This study investigates the evaporation of controlled inkjet droplets in atmospheric-pressure nonequilibrium argon plasma through experiments and modeling. Comparing the droplet evaporation model, which considers gas temperature, electron and ion collisions, and recombination reactions, with experimental results, it is found that droplet evaporation is enhanced in high-density plasma with electron and ion densities exceeding 10(19) m(-3) compared to non-ionized gaseous environments at gas temperatures under 1000 K.

Summary: Polyrotaxanes (PR) are of great interest due to their slide-ring topological structure and pulley effect. Composite materials of PR and inorganic particles, especially those with plasma-surface modifications, show higher toughness. In this study, the effect of neat PR and its composites with graphene nanoplates or carbon nanofibers was investigated using acoustic emission (AE) measurements. The results show that PR materials exhibited almost no AE signals, indicating minimal microscopic fracture before final breakage via the pulley effect.

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.
