The early stages of nanocrystal nucleation and growth are still an active field of research and remain unrevealed. In this work, by the combination of aberration-corrected transmission electron microscopy (TEM) and electrochemical characterization of the electrodeposition of different metals, we provide a complete reformulation of the Volmer-Weber 3D island growth mechanism, which has always be...

Ultrafast synthesis of a robust Ag-nanocluster metal–organic framework composite with superior photocatalytic performances, even working under continuous flow in the removal emerging contaminants from water.

We explore the occurrence of low-energy and low-temperature transient cluster burrowing leading to intact cluster inclusions. In particular, the anomalously fast (ballistic) Pt nanocluster implantation into Al and Ti substrates has been found by molecular dynamics simulations using a tight-binding many-body potential with a 1-10 eVatom low impact energy. A similar behavior has also been found f...

How do boron–nitride and Möbius–type nanobelts interact with nickel, cadmium, lead nanoclusters? In order to find the lowest energy geometries, binding energies, complex stability, electrical characteristics, we applied semiempirical tight framework, as implemented in xTB software, this subject. Our simulations demonstrate that heavy metal nanoclusters favorably connect both nanobelts, while na...

Nanocluster Im Forschungsartikel auf S. 22467 berichten Eunji Sim, Dongil Lee et al. über den Einbau eines Rhodiumhydrid-Superatoms in ein Cluster-Superatom zur Erzeugung stabilen Superatom-in-Superatom-Nanoclusters, [[email protected]24(SR)18]2−.

Based on the fact that the fluorescence response pattern of a silver nanocluster to a specific analyte is highly dependent on the nature of the DNA template, we develop a novel fluorescence turn-on assay for thiol compounds with high specificity and sensitivity by modulating DNA-templated silver nanoclusters.

A golden opportunity: the total structure of a Au(36)(SR)(24) nanocluster reveals an unexpected face-centered-cubic tetrahedral Au(28) kernel (magenta). The protecting layer exhibits an intriguing combination of binding modes, consisting of four regular arch-like staples and the unprecedented appearance of twelve bridging thiolates (yellow). This unique protecting network and superatom electron...

A large manganese-doped polyoxotitanate nanocluster Ti28MnO38(OEt)40H2, has been synthesized solvothermally. Its structure is arranged around the four-coordinate Mn(2+) dopant atom in a Keggin-type structure. A significant reduction of the band gap relative to that of undoped polyoxotitanate clusters is observed.

50 nm Magnetic nanocluster (MNC) was deliberately selected as an efficient probe for the magnetic relaxation switching (MRSw) assay. After surface modification of MNCs with poly(acrylic acid) to give PAA-MNCs, and employing streptavidin-biotin interactions for the MRSw assay model, a few tenths pM concentration of strepavidin could be determined.
