Abstract:
A nanometer is one billionth of a meter. If you blew up a baseball to the size of the earth, the atoms would become visible, about the size of grapes. Some 3- 4 atoms fit lined up inside a nanometer. Nanotechnology is about building things atom by atom, molecule by molecule. The trick is to be able to manipulate atoms individually, and place them where you wish on a structure.

Nanotechnology uses well known physical properties of atoms and molecules to make novel devices with ex ....etc

ABSTRACT:

Nanotechnology, over recent years, has seen a surge in research activity, with great potential in a wide range of applications including drug delivery, diagnostics, tissue engineering and regenerative medicine. The development of tools like the scanning tunneling microscope and the atomic force microscope has enabled researchers to observe structures on the nanoscale, where materials may exhibit different properties due to their size.
Also, the development of new materials like carbon nanotubes and buckyballs, along with th ....etc

a new bonding technique utilizing nano-scaled particles for use in high-temperature environments. The results of our investigations revealed that the method could be used to form bonds by simultaneously applying heat and pressure. Moreover, compared to a conventional Pb“5Sn-solder bond, a nanoparticle-based bond suffered no degradation in bonding strength over an elevated-temperature holding period of 1000 h at 250 °C, and its discharge characteristics were improved (i.e., increased) threefold. It is possible to extend this bondi ....etc

PRODUCTION OF BIOGENIC SILVER NANOPARTICLES USING
BOSWELLIA OVALIFOLIOLATA STEM BARK
The synthesis, characterization and application of biologically synthesized nanomaterials have become an important branch of nanotechnology. In this paper, we report the synthesis of highly dispersed silver nanoparticles using a dried stem bark of Boswellia ovalifoliolata (An endemic plant) extract as the reducing agent. After exposing the silver ions to bark extract, rapid reduction of silver ions is observed leading to the formation of silver nanopa ....etc

Abstract
A facile photochemical method was used to synthesize Ag nanoparticle (Ag NP) embedded-ZnO nanorods in this article. The as-synthesized Ag NP embedded-ZnO nanorod samples were characterized systematically by TEM, XPS, DSC, XRD and SEM. The characterization results confirmed that Ag NPs had been embedded in ZnO nanorods. The gas-sensing properties of Ag NP embedded-ZnO nanorods were also investigated. While the performances of the sensors can be enhanced by embedding Ag NPs onto the surfaces of ZnO nanorods, the response of Ag NP embed ....etc
