Summary: This study investigates the formation of boron carbide superhard particles through a liquid-phase reaction at high pressure and high temperature. The synthesized particles exhibit a rhombic hexecontahedron morphology with twelve five-vertex stars. Electron microscopy and X-ray diffraction were used to analyze the crystal structure of these particles, revealing multiple cycling twinning rather than quasi-crystalline symptoms. The specific shape of the particles is explained by the decrease of surface energy during formation at high pressure and high temperature.

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: The purely chemical synthesis of fluorine, previously believed to be impossible, was achieved in 1986 but has not been further studied since then. The mechanism of this reaction has been a mystery until recently, when it was experimentally resolved and supported by electronic structure calculations. These findings clarified the previous discrepancy and showed that the reductive elimination of F-2 requires a large excess of SbF5, occurring in the last reaction step.

Summary: This study investigates the mechanism of oxidative deintercalation of KCrSe2, revealing that the solid-state diffusion of K+ cations is the rate-limiting step in the process. Additionally, the relationship between Cr-Cr distances and magnetic order changes suggests the possibility of switching between magnetic states in CrSe2 monolayers by varying lattice parameters.

Summary: Recent studies have reported a hexagonal phase in high carbon steels, but it has been shown that this structure is actually the result of double diffraction and streaking effects caused by twins and stacking faults, rather than a superstructure. Similar misunderstandings have also been found in papers reporting exotic structures in aluminum, copper, and diamonds.

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.

Summary: This study focuses on the corrosion characteristics of AA 7075 and AA 7075 based hybrid composite fabricated using stir casting and hot rolling techniques. The results show that the hybrid composite produced by hot cross rolling exhibits better corrosion resistance compared to the base metal. The addition of a small amount of graphite improves the bonding between the matrix and reinforcements, and the hot cross rolling enhances this bonding, leading to the formation of a strong passivation oxide layer and increased charge transfer resistance, thereby improving corrosion resistance.
