The crystallization of gold nanoparticles is investigated in the gas-phase by molecular dynamics (MD) that is most relevant to their synthesis by aerosol processes (flame, plasma, or cluster beam deposition). A particle size-dependent metastable region, 200-300 °C wide, is revealed between the melting and freezing points of Au. This region decreases as the MD heating or cooling rates decrease.

Context: The property transition between metal and semiconductor is the key to improving the properties of transition metal dichalcogenides (TMDCs). The adsorption of the NbS compound in the defect state was adjusted for the first time. The hybrid system overwrites the original surface mechanism of NbS and induces indirect band gaps.

Article Synopsis
- In 2014, it was discovered that protons can move through monolayer graphene and hexagonal boron nitride (h-BN) membranes, challenging previous beliefs about their impermeability and suggesting a way for protons to be conducted via defects in these materials.
- Recent studies using advanced imaging techniques showed that the majority of chemically vapor-deposited (CVD) graphene membranes are impermeable to protons, with proton transport mainly occurring at localized defect sites, which are dynamic and can change under an electric field.
- The findings highlight the usefulness of scanning electrochemical cell microscopy (SECCM) for detailed analysis of materials like graphene, paving the way for enhanced characterization of membranes and insights into
