Summary: In this study, an in situ transmission electron microscopy (TEM) heating system was used to investigate the morphological changes of cubic Ag nanoparticles (NPs) and Ag-based core-shell structures induced by sublimation, as well as the influence of shell coverage on thermal stability. It was found that large Ag NPs (>50 nm) showed a three-stage sublimation-induced morphological change, while small Ag NPs (<30 nm) showed a uniform sublimation. The sublimation process of core-shell NPs started at stage II, and the thermal stability was enhanced by carbon shell passivation.

Summary: Surface modification is an effective approach to enhance the electrochemical performance of battery materials. However, achieving high-quality surface modification with simple processing, low cost, and mass production remains a challenge. In this study, a thermal-induced surface precipitation phenomenon is reported in Ti-doped LiCoO2, which enables an ultrathin and uniform surface modification through a simple annealing process. The surface modification layer stabilizes interfacial chemistry, improves charge/discharge reaction kinetics, and enhances cycling stability and rate capability. Dopants surface precipitation is a unique outward diffusion process that diversifies the approaches for high-quality surface modification of battery materials.

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 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: This study systematically examined the effect of heat-treatment temperature on the structural evolution and mechanical response of Haynes (R) HR-224 (R) alloy, revealing a significant increase in room temperature tensile strength and a reduction of ductility under 600-800 degrees C/2 h heat treatment conditions. Discontinuous precipitation (DP) of (gamma + gamma')/M23C6 was identified as the main structural process affecting the observed mechanical behavior of the material.

Summary: This study used electron-beam irradiation to observe surface structural transitions on thin Au (1 0 0) and (1 1 0) specimens at different current densities. It was found that at low current densities, nanometer polygonal holes were formed with atomically sharp facets on both surfaces, while at higher current densities, the holes became filled and some facet surfaces were roughened.

Summary: Intermetallic phases in Mg-8Zn-6Al-1Sm alloys in both as-cast and peak-aged conditions were investigated. The study identified various intermetallic phases, such as Mg44Al15Zn41, Mg5Zn2Al2, Mg-32(Al,Zn)(49), and Al2Sm. Aging treatment showed a possible phase transformation and revealed precipitate constituents, including i phase, MgZnAl cubic phase, MgZn2 phase, Mg4Zn7 phase, and aperiodic structures. The study also found multiple orientation relationships between precipitates and the Mg matrix, and observed ordering planar faults in MgZn2 precipitates. The calculations demonstrated the superior strengthening effect of Mg-Zn-Al precipitates and attributed the high strength of the alloy to semi-continuous intermetallic skeletons and Mg-Zn-Al precipitates.

Summary: The use of guanidinium iodide (GAI) cation as an interface engineering technique in perovskite solar cells improves stability by passivating defects on surfaces and grain boundaries. However, the relationship between structural and photophysical properties is not well understood. This study demonstrates that an optimal concentration of GAI can eliminate excess PbI2, improve crystallinity, and increase grain size. Higher concentrations induce the formation of new phases and reduce crystallinity and grain size. GAI treatment also helps remove microscale heterogeneities, resulting in optimum device performance.

Summary: X-ray diffraction and transmission electron microscopy confirmed the self-assembly of functional monomer 10-MDP into nano-layers at adhesive-tooth interfaces, which contribute to the mechanical strength of adhesives. Focused-ion-beam milled cross sections and scanning probe microscopy were used to observe and evaluate the 3-dimensional spreading and mechanical properties of nano-layering. The formation of self-assembled nano-layering strengthens the adhesives and may improve the clinical longevity of the bond to dentin.

Summary: Co-doped ceria nanopowders, Ce1-xCoxO2 (x = 0.1, 0.2 and 0.3mol.%), were synthesized using citrate-nitrate auto-combustion method at 500 degrees C. The crystal structure of ceria was confirmed to be cubic fluorite by X-ray diffraction analysis. UV-Visible and FT-IR spectroscopic analyses revealed the charge transfer and functional groups in the nanoparticles. Photoluminescence spectroscopy confirmed the visible light emission due to vacancies, with different wavelengths corresponding to oxygen and cerium bands. Scanning electron microscopy and high resolution transmission electron microscopy were utilized to analyze the porosity, particles size, shape, and distribution. The presence of constituent elements and weak ferromagnetism were confirmed by energy dispersive X-ray spectroscopy and vibrating sample magnetometry, respectively.

Summary: The non-covalent functionalization of graphene with mixed surfactants is an effective method for preparing stable graphene dispersions. The presence of electrolyte significantly affects the adsorption process of pure surfactants on solid surfaces. Increasing ionic strength of electrolyte reinforces stretching of surfactants adsorbed on graphene, leading to a clear volume expansion in the structure of graphene-surfactant mixture hemi-spherical micelles.

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.
