Summary: The study investigates the growth of AZO on silicon nanowires (SiNWs) and examines its morphological evolution. It is found that AZO initially forms crystalline nano-islands and later coalesces into a conformal polycrystalline shell on the substrate. The deposition process of AZO leads to the growth of a polycrystalline matrix between SiNWs, resulting in the formation of hook-shaped SiNWs covered by AZO.

Summary: Plasmonic properties of aluminium nanowires in the UV and far UV region were investigated in this study. The study demonstrated that aluminium nanowires can serve as an excellent alternative to Ag or Au for enhancing optical activity. The size and spacing of the nanowires, as well as the embedding material, were found to significantly impact the type of surface plasmon energies that can be generated.

Summary: Integration of GaP layers on silicon substrates using AsH3 pre-exposure followed by a PH3-based GaP epitaxial growth allows the development of very promising processes for the photovoltaic industry. However, many of the growth routines using this approach suffer from reproducibility issues, leading to poor quality layers. This lack of knowledge on the mechanisms behind the formation of common planar defects and their dynamics hinders the successful transfer of the method to new epitaxial systems.

Summary: Felicitously incorporating noble metals with transition metals to fabricate composite nanoagents with diverse shape and microarchitecture is a promising solution for obtaining highly effective catalysts. In this study, a facile and flexible synthesizing tactic, or Galvani substitution modulated self-assembly protocol, was used to fabricate Cu nanowire (core)-Pt nanoparticle (shell) microarchitecture (Cu-NWs@Pt) with a porous structure. The bimetallic nanowires with a Cu-Pt alloy sublayer and ordered Pt nanograins exhibited enhanced catalytic activity. The catalytic ability further increased with rising Pt/Cu molar ratios, and the Cu0.6Pt0.4 composition even exceeded Pt-NPs, maintaining 89% of the initial catalytic ability after 5 recycling runs.

Summary: The study investigated the surface structure of Ni plating films reacted with methane at 800 degrees C using SEM and TEM. The reaction with methane eroded the surface of the Ni plating film, resulting in a nano-roughened surface with a hexagonal close-packed structure of about 3 nm thickness. The carbon layer deposited on the Ni plating film was evaluated through electron energy loss spectroscopy, which showed an increase in hydrogenated or oxidized carbon atoms on the surface.

Summary: The nanostructured samples of BFBT were synthesized by mixing a stoichiometric ratio of the reactants (Bi2O3 -Fe2O3 - BaTiO3) in a high-energy planetary ball mill system. Structural characterization of the mechanosynthesized powder for 5h followed by heat-treatment at 673, 873, and 1073K for 5 h has been investigated through the X-ray diffraction technique. The effect of the heat-treatment temperature of nanostructured BFBT samples on their conductivity is studied in conformity with Mott's theory.

Summary: This study investigates the effects of surface potential on the carrier mobility and piezoresistance of core-shell silicon carbide nanowires (SiC NWs) for small and sensitive SiC-microelectromechanical systems sensors. It is found that the electric field induced by the fixed oxide charge can determine both the electrical conduction and the charge carriers in the NWs. Additionally, the piezoresistive effect is enhanced by the electric field of the dielectric.

Summary: This study investigates the formation of calcium-silicate-hydrates (C-S-H) in lime mortars with the addition of nano-Ca(OH)2 and nano-SiO2 at 23.3 degrees C. The results show the evolution of amorphous phases to crystalline phases, with the crystalline phase identified as afwillite. The presence of afwillite may have implications for the performance of the lime mortars.

Summary: The crystallographic orientation of nanoparticles on the surface of solid crystalline matrix plays a crucial role in their activity, and predicting this orientation can be advantageous in materials science. This study presents a method to predict crystallographic orientation by determining structure compatibility of two crystal structures based on overlapping atoms. The compatibility of ZnS nanoparticles with tetrahedral kaolinite surface was studied and results were consistent with molecular simulations and high-resolution transmission electron microscopy analysis.
