We study nanoscale phase separation in iron-pnictides and its relation to doping and electronic degeneracies across the tetragonal-orthorhombic and uncollapsed to the collapsed tetragonal phases

Nonlinear vibration analysis of dynamic response of carbon nanotube has created noble attention globally because of their properties and applications in tomorrow’s society.

Radial Basis Function Neural Network (RBFNN) has been accomplished to evaluate the effect of the different operating parameters, namely the hourly space velocity, the reaction temperature, and [C0₂: CH₄] mole ratio on the conversion and formation of the different components involved in the dry reforming of methane over Ni/MgO catalyst. : CH₄ ] mole ratio on the conversion and formation of the different components involved in the dry reforming of methane over Ni/MgO catalyst.

The vibrations of carbon nanotubes under the influences of various internal and external forces have been subjects of interests for some years. These researches have not really considered the effects of surface energy and initial stress which are very important from both material and mechanical aspects of views.
