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: The report describes a novel low temperature sol-gel method for synthesizing nanostructured Hausmannite, Mn3O4, with very small crystallite size and high phase purity. Analysis using Raman and XPS confirms the presence of Mn in a +4 valence state and the purity of the phase. UV-visible absorption spectra show broad charge transitions associated with different Mn valence states, while DC electrical conductivity is significantly higher compared to single crystalline Mn3O4.

Summary: Supercapacitors, which have high energy storage capabilities and do not require manual maintenance, face challenges due to their low energy density and capacity. Recently, 2D materials, particularly 2D transition metal carbonitrides (MXenes), have attracted interest for energy storage devices due to their large surface area and fast ion transport pathways. MXenes have transition metal and carbon/nitrogen layers with active functional groups on the surface, which enhance their hydrophilicity and wettability in aqueous electrolytes and make them suitable for energy storage applications.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
