Abstract
Cetyl trimethyl ammonium bromide (CTAB) stabilized gold(III) salt in chloroform was reduced using
NaBH4 in the presence of commercially available methanethiol-polyphoResinTM to obtain polystyrene
micro beads with gold nanoparticles on their surface.
Experimental Section (a)Materials.
Using polarized SR on single crystal samples, which allows the identification of different orientations of chemical bonds, Smith et al 9 have provided an excellent basis for the assignment of the different structures in S K-XANES spectra of photographic materials which involves S-Au or S-Ag bond.

The final stress equation typically used is Eq. 1 which
consists of three orthogonally measured strain values and the moduli values (Ehkl and νhkl the hkl
specific Young's modulus and Poisson's ratio respectively) of the material being measured [1].

The main aim is the correct propagation of the random uncertainty (inherently unpredictable

In this case, the amount of material removed from the cutting tool, in the area where the elastic deformation has great values will determine a lower depth of cut than in other sections of the work piece.
Experimental Stand In order to determine the elastic deformations caused by variations of the cutting force during processing we will consider a work piece with a constant diameter made out of the RSt 37-1.1 material (mild steal).

Introduction
Clay soils used in construction of road pavements are the most in demand among building materials used in construction of automobile roads.
Natural-climatic conditions and, as a result, the moisture of subgrade soils and materials of pavement layers are considered to be key factors contributing to changes in the strength and deformability values of soils during operation of automobile roads [12, 13].

Introduction
Generally, fretting wear corresponds to a situation where the material removal is due to a repetitive
sliding contact with small contact loads.
However, wear behavior is more sensitive to the material/mechanical properties such as the changed hardness, subsurface deformation in a water lubricant condition [1, 2].
In this experiment, Zirconium alloy was used as a fuel rod specimen that had a 9.5mm diameter, 0.6mm thickness with a 40mm length; this commercial alloy has been used as nuclear fuel claddings and for the main components of fuel assembly materials.
Acknowledgements This study has been carried out under the Nuclear R&D Program by Ministry of Science and Technology in Korea.
