Ag nanoclusters consisting of several AQ:1 to a hundred atoms with diameters less than 2 nm show molecule-like properties, including discrete electronic AQ:2 transitions and strong fluorescence. They have received considerable research interest due to their unique optical, electrical and chemical properties and potential applications in chemicaland biosensing. Ag nanoclusters exhibit excellent ...

Low-temperature aqueous chemical growth methods have shown great potential in the synthesis of ZnO nanostructures. Hexamethylenetetramine (HMTA) is the most common chemical substance used in the hydrothermal synthesis. In this study zinc oxide nanoparticles were prepared via hydrothermal growth using zinc acetate dihydrate and sodium hydroxide, as precursors instead of HMTA, as it is commercial...

Surfactant based aqueous foams provide a very efficient and simple chemical route for the synthesis of various nanomaterials with controllable structure, size and shape. In this present work, a one-step process for the synthesis of morphologically controlled CdS nanoclusters has been described. Aqueous soluble CdCl2 and the surfactant AOT are homogeneously mixed together to produce a stable aqu...

nanobiotechnology appears to be an emerging science which leads to new developments in the field of medicine. importance of the magnetic nanomaterials in biomedical science cannot be overlooked. the most commonly used chemical methods to synthesize drugable magnetic nanobeads are co-precipitation, thermal decomposition and microemulsion. however monodispersion, selection of an appropriate coati...

The use of heterogenization as a method for achieving clean synthesis is discussed. The chemical modification of mesoporous solids can be used to make a range of catalysts, including solid acids and bases, and stable metal complexes for selective oxidations and other reactions. By avoiding an aqueous quench stage in the separation, the heterogenization of catalysts and reagents can lead to subs...

silver is composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. silver nanoparticles have been a potent antibacterial, antifungal, anti-viral and anti-inflammatory agent. a simple, eco-friendly, inexpensive biosynthetic method was employed to synthesize silver nanoparticles.  the present study aimed at the comparative study of silver nanopartic...
