Summary: The influence of organic surface chemistry on the properties and mechanical behavior of inorganic nanomaterials is not well understood. This study demonstrates that the mechanical strength of a silver nanoplate can be controlled by the binding enthalpy of its surface ligands. The results show a size-dependent coupling between chemistry and mechanics at the nanoscale, with surface ligands affecting the plastic deformation and global mechanical strength of the nanoplate.

Summary: Inorganic nanomaterials can be influenced by organic surface chemistry, which can modulate the mechanical strength of silver nanoplates. A continuum-based core-shell model reveals that the interior of the nanoplate retains bulk-like properties, while the surface shell has yield strength values determined by surface chemistry. Electron diffraction experiments show lattice expansion and disordering of atoms at the nanoplate surface, which are directly related to the coordinating strength of the surface ligands.

Summary: Inorganic nanocrystal gels retain unique properties of individual nanocrystals and can be assembled into colloidal materials using various mechanisms, such as controlled destabilization, direct bridging, depletion, coordination bonding, and dynamic covalent bonding. Each mechanism has different impacts on gel properties and offers advantages in terms of stability, reversibility, or tunability. These approaches, utilizing nanocrystal surface chemistry or the addition of small molecules, provide new opportunities for the design of reconfigurable materials and fueled assemblies.

Summary: This study reports the synthesis of silver nanodendrites using Hamelia patens plant extract as a reducing agent. The nanodendrites show branches with a length of around 800 nm and a width of around 300 nm, as observed through SEM and TEM micrographs. The chemical composition and crystal structure of the products are confirmed by XRD analysis. UV-Vis spectroscopy reveals the surface plasmon resonance band typical of Ag nanostructures. FT-IR spectroscopy demonstrates the degradation of MB and RhB by the nanodendrites, while adsorption of MO is observed. The UV-Vis technique shows high degradation efficiency of 98% for MB and 96% for RhB in Ag dendrites, with 93% adsorption of the MO dye.

Summary: The perovskite-type phase CaCu3Ti4O12 has promising dielectric properties, but the phenomenon of giant permittivity in this material has not been fully explained. In this study, Europium with similar electronegativity and ionic radius as Calcium was tested as a partial or complete substitute. A series of materials, including CaCu3Ti4O12, Eu0.4Ca0.6Cu3Ti4O12, and EuCu3Ti4O12, were prepared using a sol-gel method and sintering. The influence of microstructure and phase composition on the dielectric properties of the samples, as well as the effect of sintering temperature, was investigated. Secondary phases and microstructure were found to play a significant role in improving the permittivity values, which were found to be giant at higher frequencies but significantly different for specific compositions.

Summary: The corrosion resistance of the AA2024-T3 alloy can be significantly improved by using top protective sol-gel hybrid organic-inorganic coatings. Samples with Ce nanoparticles incorporated in the anodic layer pores displayed better performance compared to samples with only the coating. This research reveals the self-healing capability against corrosion of the sol-gel coating in the presence of Ce nanoparticles, as well as the good coverage of defective regions within the oxide by the hybrid layer. It opens up a new paradigm in maximizing the corrosion resistance for non-ferrous anodized alloys.

The electromagnetic responses of the SDM device in different modes were studied through numerical simulations and experiments. Increasing the structure height of the SDM device resulted in red-shifted resonances and stronger intensities. This study provides a new design strategy for the development of frequency filtering, polarization switching, and resonance modulation characteristics in THz-wave applications.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
