In this work, fluorescent gold nanocluster (AuNC) decorated polycaprolactone (PCL) nanofibers (AuNC*PCL-NF) for real time visual monitoring of Hg(2+) detection at ppt level in water is demonstrated. The resultant AuNC*PCL-NF exhibiting remarkable stability more than four months at ambient environment and facilitates increased accessibility to active sites resulting in improved sensing performan...

Reaction of Cd(OAc)2·2H2O and selenourea in primary-amine/secondary-amine cosolvent mixtures affords crystalline CdSe quantum platelets at room temperature. Their crystallinity is established by X-ray diffraction analysis (XRD), high-resolution transmission electron microscopy (TEM), and their sharp extinction and photoluminescence spectra. Reaction monitoring establishes the magic-size nanoclu...

Tiara-like thiolated group 10 transition metal (Ni, Pd, Pt) nanoclusters have attracted extensive interest due to their fundamental scientific significance and potential application in a number of fields. However, the properties (e.g. the absorption) evolution with the ring size's increase was not investigated so far to our best knowledge, due to the challenge of obtaining a series of nanoclust...

Clusters play important role for understanding and transferring microscopic to macroscopic properties.Geometric and electron properties of Small nickel clusters up to the tetramer has been investigated by Density Functional Theory (DFT). Raising the number of nickel clusters atoms were indicated decreasing the average equilibrium (Ni-Ni) distance of atoms and also the binding energy of per atom...

in recent years there has been considerable interest in the structures, energies and thermodynamics of(gan)4 clusters and it is the subject of many experimental and theoretical studies because of theirfundamental importance in chemical and physical process. all calculation of this study is carried outby gaussian 98. geometry optimization for (gan)4 nanocluster are be fulfilled at b3lyp, b1lypan...

Interface microenvironment mediated surface-Mn 2+ -involving direct charge transfer with interfacial alkylamines was for the first time revealed by using an atomically precise semiconductor nanocluster model uniform near-surface Mn ions.

The tetradecanuclear FeIII pivalate nanocluster [Fe14O10(OH)₄(Piv)18], comprising a new type of metal oxide framework, has been solvothermally synthesized from a hexanuclear iron pivalate precursor in dichlormethane/acetonitrile solution. Magnetic measurements indicate the presence of very strong antiferromagnetic interactions in the cluster core.

Mixtures of an appropriate carboxylic acid and n-butylstannoic acid constitute modular gelation systems, in which the formation of a well-defined 'tin-drum' nanocluster subsequently underpins the hierarchical assembly of nanostructured fibres, which form self-supporting gel-phase networks in organic solvents.
