'Golden' silver nanoparticle looks and behaves like gold
(Phys.org)—In an act of "nano-alchemy," scientists have synthesized a silver (Ag) nanocluster that is virtually identical to a gold (Au) nanocluster. On the outside, the silver nanocluster has a golden yellow color, and ...
Scientists demonstrate first color-tunable and first graphene-based LED
(Phys.org)—Currently, all light-emitting diodes (LEDs) emit light of only one color, which is predefined during fabrication. So far, tuning the color of light produced by a single LED has never been realized, despite numerous ...
How many gold atoms make gold metal?
Researchers at the Nanoscience Center at the University of Jyväskylä, Finland, have shown that dramatic changes in the electronic properties of nanometre-sized chunks of gold occur in well-defined size range. Small gold ...

Researchers turn gold nanoclusters into 12-sided dodecahedron crystals
A*STAR researchers have devised a way to destabilize gold nanoclusters so that they form tiny atomic nuclei that then grow together into perfectly proportioned, 12-sided dodecahedron crystals. These unique polyhedra have ...

Advances in the controlled synthesis and applications of luminescent metal nanoclusters
Luminescent metal nanoclusters are a new class of materials consisting of several, to tens of, metal atoms. These materials not only provide the missing link between atomic and nanoparticle behaviors in metals, but also present ...

Controlling nanoclusters with surface defects could lead to construction of nanodevices (w/ Video)
(Phys.org)—In nanoscience, the ultimate goal is to design better materials and devices by controlling the positions of the atoms, molecules, and molecular clusters on a substrate with exact precision. In a new study, researchers ...
Researchers develop new technique for heterogenizing homogenous nano catalysts
(Phys.org)—Catalysts are substances that speed up the rates of chemical reactions without themselves being chemically changed. Industrial catalysts come in two main types - heterogeneous, in which the catalyst is in a different ...
