Summary: In this study, it was found that the presence of micro/nanostructured surfaces significantly affects the evaporation rate of droplets, with the wettability and volume of the droplets further influencing this effect. Theoretical and experimental results showed agreement when the scale of the solid-liquid-vapor interface (slv) was negligible. For microstructured surfaces, the scale of the slv interface could reach 253-940 μm, and the evaporation rate at the slv interface accounted for 16-48% of the total evaporation rate. The scale and rate of the slv interface increased with a decrease in the initial contact angle or an increase in the droplet volume. These findings are important for practical engineering and medical applications involving droplet evaporation on micro/nanostructured surfaces.

Summary: In this study, uniformly porous and solid core porous particles were synthesized by aerosol spray pyrolysis route using a one-step process, which is of high interest for pharmaceutical and catalytic applications. The effect of synthesis parameters on the core size, surface area, and porosity of the core-shell structures was validated through morphological evaluation and nitrogen adsorption and desorption isotherms. Different surfactants (Brij-58, CTAB, P123) at various concentrations and combinations, as well as different core type compositions (NaCl, CeO2, and Ce0.8Zr0.2O2), were evaluated for the controlled synthesis of silica core-shell particles using a scalable synthesis method.

Summary: Nanoscale patterning of inorganics is crucial for advanced electronic, photonic, and energy devices. In this study, the sequential infiltration synthesis (SIS) method was used to fabricate Ru metal nanostructures in polystyrene-block-polymethyl methacrylate (PS-b-PMMA) templates without any pretreatment. The selective interaction between RuO4 and the aromatic C=C and C-H groups in PS allows for the formation of Ru nanolines.

Summary: Diamond/Cu composites with Ti-coating were prepared using a liquid-solid separation technology. The formation of TiC phase improved the interfacial bonding between diamond and copper, resulting in a thermal conductivity of 457.22 W·m(-1)·K-1 for 40 vol.% Ti-coated diamond/Cu composites. The thermal conductivity showed a significant decrease with increasing TiC layer thickness, reaching a critical value of approximately 260 nm, as estimated by the differential effective medium model.

Summary: A novel pressure-induced supercritical phase nucleation method is proposed for synthesizing monolayer MoS2 films, without the need for promoters. The method avoids contamination from heterogeneous promoters seen in existing techniques. The size of MoS2 crystals on the substrate is influenced by the wetting area of precursor droplets, while the formation of continuous films is controlled by the coalescence of droplets. The nucleation site density can be adjusted by the supersaturation of the supercritical fluid solution, providing new possibilities for controlled growth of MoS2 and other two-dimensional materials.

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.

The microstructure and performance of the membranes were investigated, and a method to predict drug release properties was proposed. The results showed that the composition of the mixed solvent significantly affected the overall performance of CDA membranes, and the release rates of drugs were related to Δdelta and the intrinsic viscosity of CDA.
