Proteins have proven to be particularly attractive as effective ligands in the synthesis of nano- and subnanoscaled materials because of their multiple chelating and functional groups imparting unique functionalities. However, protein-directed fluorescent metal cluster synthesis is still a challenge but a promising area of research. Here, we report on the synthesis of new water-soluble, stable,...

Oxide-supported transition-metal clusters and nanoparticles have attracted significant attention owing to their important role as components of model catalysts, sensors, solar cells and magnetic recording devices. For small clusters, functionality and structure are closely interrelated. However, knowledge of the structure of the bare cluster is insufficient as the interaction with the chemical ...

The most commonly used method for the production of thin films is based on deposition of atoms or molecules onto a solid surface. One of the suitable method is to produce high quality metallic, semiconductor and organic thin film is Ionized cluster beam deposition (ICBD), which are used in electronic, robotic, optical, optoelectronic devices. Many important factors such as cluster size, cluster...

The structural and electronic states of defective complexes in the Si 29 cluster with participation carbon hydrogen atoms were determined by method non-conventional strong binding (MNSB) combination molecular dynamics. It is shown that silicon clusters form a bridge bond two localized hexagonal position at center cell, forming defect : C i type. introduction into results formation -H-Si complex...

We present a subspace projection technique to conduct large-scale Kohn-Sham density functional theory calculations using higher-order spectral finite-element discretization. The proposed method treats both metallic and insulating materials in a single framework, and is applicable to both pseudopotential as well as all-electron calculations. The key ideas involved in the development of this meth...

A facile procedure to fabricate the hydrophobic surfaces of calcium carbonate-polymer composites has been well described. Nano-sized highly ordered CaCO3 clusters i.e. calcite/vaterite have been synthesized by simple precipitation in the presence of template made of cationic surfactant: cetyl trimethyl ammonium bromide (CTAB) and different non-ionic amphiphilic triblock copolymers comprising of...

Silver metal clusters have been formed in soda lime glass by high-energy heavy ion diation at ISL. The metal cluster formation was detected with X-ray absorption spe copy (EXAFS) in fluorescence mode, and the shape of the clusters was imaged transmission electron microscopy. While annealing in reducing atmosphere alone a leads to the formation of metal clusters in Ag containing glasses, where t...
