چکیده

Precise identification and in-depth understanding of defects in nanomaterials can aid rationally modulating defect-induced functionalities. However, few studies have explored vacancy ligand-stabilized metal nanoclusters with well-defined structures, owing to the substantial challenge synthesizing isolating such defective nanoclusters. Herein, a novel copper hydride nanocluster, [Cu36H10(PET)24(PPh3)6Cl2] (Cu36; PET: phenylethanethiolate; PPh3: triphenylphosphine), is successfully synthesized at gram scale via simple one-pot reduction method. Structural analysis reveals that Cu36 distorted half cubic evolved from perfect Nichol's cube. The two surface vacancies are found be principal imperfections, which result some structural adjustments, including atom reconstruction near as well ligand modifications (e.g., substitution, migration, exfoliation). Density functional theory calculations imply above-mentioned considerable influence on electronic structure properties. modeling suggests formation rather than cube driven by enlargement energy gap between highest occupied molecular orbital lowest unoccupied nanocluster. evolution induced provides atomically precise insights into readjustment local introduces new avenues for chemistry nanomaterials.

Thermodynamic stability of ligand-protected metal nanoclusters

Despite the great advances in synthesis and structural determination of atomically precise, thiolate-protected metal nanoclusters, our understanding of the driving forces for their colloidal stabilization is very limited. Currently there is a lack of models able to describe the thermodynamic stability of these 'magic-number' colloidal nanoclusters as a function of their atomic-level structural ...

Vacancy-stabilized crystalline order in hard cubes.

We examine the effect of vacancies on the phase behavior and structure of systems consisting of hard cubes using event-driven molecular dynamics and Monte Carlo simulations. We find a first-order phase transition between a fluid and a simple cubic crystal phase that is stabilized by a surprisingly large number of vacancies, reaching a net vacancy concentration of approximately 6.4% near bulk co...

Understanding Digestive Ripening of Ligand-Stabilized, Charged Metal Nanoparticles

Most syntheses of thiolate-protected metal nanoparticles (NPs) include a thermochemical step in which the as-prepared, polydisperse NPs are transformed to a narrower size distribution in a poorly understood process known as digestive ripening (DR). Previous theoretical approaches considered either surface and electrostatic contributions or surface and ligand-binding contributions. We show that ...

Vacancy-controlled ultrastable nanoclusters in nanostructured ferritic alloys

A new class of advanced structural materials, based on the Fe-O-vacancy system, has exceptional resistance to high-temperature creep and excellent tolerance to extremely high-dose radiation. Although these remarkable improvements in properties compared to steels are known to be associated with the Y-Ti-O-enriched nanoclusters, the roles of vacancies in facilitating the nucleation of nanocluster...
