This paper discuss about a novel technique of developing a nano-structured polypyrrole biosensor for measurement of very low concentrations of hydrogen peroxide in liquid media. The proposed fabrication method is very effective in growing a nano-structured conducting polymer layer on a planar conducting substrate. In addition enzyme loading was done under a high electric field of 1000V/m. The d...

Nano-composite permanent magnetic material is a new type permanent magnetic material, and it is the synthesis of soft and hard magnetic phase within nanoscale. On the basis of exchange coupling hard magnetizing theory, nano-composite permanent magnetic material can at the same time have high residual magnetization intensity of soft magnetic phase and high coerccivity of hard magnetic phase, and...

The remanence of an isotropic nanocrystalline exchange-coupled composite system (comprising hard and soft magnetic phases) is investigated analytically within a simple (onedimensional) micromagnetic model, in which only exchange and anisotropy energies are considered. For a soft grain with size much less than its own Bloch wall width, our analysis shows that the magnetization distribution in th...

The progress of full-field electromagnetic tools coupled to increasingly powerful computing hardware offer the possibility of modelling accurately micro/nano-structured fibres. Together with the advances in fabrication methods, this opens the door to the realization of optimized designs with growing complexity. Three examples of simulations are presented here to illustrate the application of ge...

Present work demonstrates a detail simulation results on enhanced generation of localized surface plasmon resonance (LSPR) field condition in a periodically varying height metal nanopillars. This simulation work has been carried out using COMSOL Multiphysics software. LSPR field condition study in metal nanostructure is important for different fields of applications which include chemical and b...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

A major technological barrier to achieving superior properties of nano-structured composite materials is the difficulty of dispersing fillers uniformly in a host matrix. The existing nanocomposite manufacturing processes achieve property improvements through chemical modifications of filler structures and utilization of chemical interactions between the chemically modified fillers and matrix po...
