During the deposition of a metallic material on substrate, nanocluster-array structure with an extremely narrow gap is formed transiently at transition between isolated clusters and continuous film. It known that nanocluster array shows unique electrical property different from The changes significantly depending its morphology, precise control time indispensable to obtain desired property. How...

We investigated the hydrolysis of TiIV along with naturally abundant AlIII ions and reported formation a stable semiconducting nanocluster. Interestingly, this compound exhibits an unusual odd-membered ring structure also represents largest Al-containing polyoxotitanium cluster (PTC) observed thus far. The presence shell organic ligands as well incorporation hetero-AlIII endowed nanocluster hig...

DNA-templated silver nanoclusters are promising biological fluorescence probes due to their useful fluorescence properties, including tunability of emission wavelength through DNA template sequence variations. Ag K-edge EXAFS analysis of DNA-templated silver nanoclusters has been used to obtain insight into silver nanocluster bonding, size, and structural correlations to fluorescence. The resul...

The molecular features of synapses in the hippocampus underpin current models of learning and cognition. Although synapse ultra-structural diversity has been described in the canonical hippocampal circuitry, our knowledge of sub-synaptic organisation of synaptic molecules remains largely unknown. To address this, mice were engineered to express Post Synaptic Density 95 protein (PSD95) fused to ...

Hg(2+) ions are bound to a 1,4-benzenedimethanethiol (BDMT) monolayer assembled on a Au electrode. Electrochemical reduction of the Hg(2+)-BDMT monolayer to Hg(+)-BDMT (at E degrees =0.48 V) and subsequently to Hg(0)-BDMT (at E degrees =0.2 V) proceeds with electron-transfer rate constants of 8 and 11 s(-1), respectively. The Hg(0) atoms cluster into aggregates that exhibit dimensions of 30 nm ...

The spatial organization of K-Ras proteins into nanoclusters on the plasma membrane is essential for high-fidelity signal transduction. The mechanism underlying K-Ras nanoclustering is unknown. We show here that K-Ras.GTP recruits Galectin-3 (Gal-3) from the cytosol to the plasma membrane where it becomes an integral nanocluster component. Importantly, we show that the cytosolic level of Gal-3 ...

The atomic-structure characterization of alloy nanoclusters (NCs) remains challenging but is crucial in order to understand the synergism and develop new applications based upon the distinct properties of alloy NCs. Herein, we report the synthesis and X-ray crystal structure of the Pt1Ag28(S-Adm)18(PPh3)4 nanocluster with a tetrahedral shape. Pt1Ag28 was synthesized by reacting Pt1Ag24(SPhMe2)1...

Evidence is provided from studies on natural and artificial biofluids that the sequestration of amorphous calcium phosphate by peptides or proteins to form nanocluster complexes is of general importance in the control of physiological calcification. A naturally occurring mixture of osteopontin peptides was shown, by light and neutron scattering, to form calcium phosphate nanoclusters with a cor...
