Nano-graphene oxide (nano-GO) is a new class of carbon based materials being proposed for biomedical applications due to its small size, intrinsic optical properties, large specific surface area, and easy to functionalize. To fully exploit nano-GO properties, a reproducible method for its production is of utmost importance. Herein we report, the study of the sequential fracture of GO sheets ont...

Nano-ZnO has been successfully synthesized via hydrothermal technique to evaluate as plant pathogenic antibacterial agent. The crystalline and morphological structures of ZnO were examined using X-ray diffraction and scanning electron microscopy respectively. The morphological structure of synthesized ZnO was nano-rod with an average aspect ratio about 8. The antibacterial effect of ZnO nanorod...

Standard approaches to magneto-mechanical interactions in thermal magnetic crystalline solids involve Landau functionals in which the lattice anisotropy and the resulting magnetization easy axes are taken explicitly into account. In glassy systems one needs to develop a theory in which the amorphous structure precludes the existence of an easy axis, and in which the constituent particles are fr...

X-Ray Raman Spectroscopy (XRS) is used to study the electronic properties of bulk lithium borohydride (LiBH(4)) and LiBH(4) in porous carbon nano-composites (LiBH(4)/C) during dehydrogenation. The lithium (Li), boron (B) and carbon (C) K-edges are studied and compared with calculations of the starting material and intermediate compounds. Comparison of the B and C K-edge XRS spectra of the as-pr...

Achieving high elasticity for silicon (Si) nanowires, one of the most important and versatile building blocks in nanoelectronics, would enable their application in flexible electronics and bio-nano interfaces. We show that vapor-liquid-solid-grown single-crystalline Si nanowires with diameters of ~100 nm can be repeatedly stretched above 10% elastic strain at room temperature, approaching the t...

This paper reports the feasibility of synthesis and characterization of One Dimensional nano scale Porous Silicon Photonic Crystals (1D-PSPC) prepared using electrochemical anodization of p-type crystalline silicon wafer by adjusting the current densities. Two structures PSPC1 and PSPC2 with current density 25 and 35mA/cm with 10 minutes of etching time were prepared. Structural and optical pro...

Ordered mesoporous Cd(x)Zn(1-x)S ternary compound semiconductors were prepared with a simple nano-casting method using 3-D cubic Ia3d meso-structured silica, KIT-6, as a hard-template with the easily available precursors of 3CdSO4 x 8H2O and ZnSO4 x 7H2O. Thermal reduction of impregnated precursors resulted in the crystalline networks within the mesopore of the silica template, then the ordered...

Scaling behaviour has been observed at mesoscopic level irrespective of crystal structure, type of boundary and operative micro-mechanisms like slip and twinning. The presence of scaling at the meso-scale accompanied with that at the nano-scale clearly demonstrates the intrinsic spanning for different deformation processes and a true universal nature of scaling. The origin of a ½ power law in d...
