Abstract

Heat transfer is the moment of energy, due to difference in the temperature of a body. There are three modes of heat transfer viz. conduction, convection and radiation. In this, the analysis is to be made through an alloy, so the characteristic equations of conduction are considered. In the numerical analysis, this moment is analyzed with the help of equations. The Finite Element Analysis (FEA) has become an effective way to numerically simulate heat transfer. The objective of the study was to simulate heat transfer process in different orientations of the work-piece. Analysis has been carried out on Nimonic 80A alloy with their basic properties. First time, one end of the rod is kept at room temperature and the other end at 600K. The variation is observed and drawn in the form of a graph. Another time, one surface of the specimen is kept at room temperature and the other surface at 600K temperature. The variation of temperatures in both cases were analyzed and is found that heat flows from higher temperature to lower temperature up to a certain distance and after that, the material is at room temperature. The color codes distinguish the hotness and coldness of the work-piece.

Abstract

The zinc oxide (ZnO) thin films have been obtained by sol gel spin coating technique on to the glass substrates kept at 400⁰ C. The conditions have been optimized to obtain quality films. Optical absorption studies to find optical band gap of the films have been made through UV-Visible spectroscopy in the spectral range of 200 -1100 nm. Effect of spin speed on the optical band gap of these films has been studied. Results show that optical band gap of the films get modified on increasing the spin speed of films.

Abstract

Dielectric properties along with photoluminescence phenomenon of ion induced Polyethylene naphthalate (PEN) were 3+ 6+ 10+ analyzed. Li , C , Ni ion beams were used to analyze the modifications induced by swift heavy ions as a function of ion 11 12 2 fluence, ranging from 1x10 to 3x10 ions/cm . Blue shift is observed in PL behavior. Dielectric constant (ε′) for pristine and irradiated samples has also been calculated, which increases with the increase in ion fluence.

Abstract

To investigate the relationship between the particle size and the Raman bands of TiO₂ nanoparticles, two different size- selected samples of TiO₂ nanoparticles were investigated using Transmission Electron Microscopy (TEM), High Resolution TEM (HRTEM), X-ray Photoelectron absorption Spectroscopy (XPS), and Fourier Transform Raman spectroscopy (FTRaman). In the Raman spectra, both broadening and shifts of the Raman bands with decreasing particle diameter were observed. In this paper, these Raman shifts are attributed to the effects of decreasing particle size on the force constants and vibrational amplitudes of the nearest neighbor bonds.

Abstract

The Seebeck Coefficient for the strontium ferrites Sr RE Fe O (where RE = Dy, x = 0.0, 0.10, 0.20 and 0.30), which have 1-x x 12 19 been prepared by employing the ceramic technique, were studied in the temperature range 313-473K. The value of thermoelectric power seems to increase with increasing temperature where as the AC conductivity has been observed to be independent of frequency at high temperatures for all values of x. In the relatively low temperature region, thermoelectric power value has been found to be negative confirming that the majority of carriers are electrons thereby indicating the rare earth substituted strontium ferrites to be classified as n-type semiconductors. The X-ray diffraction patterns show that the prepared samples have a single phase. The lattice parameters 'c' and 'a' were found to decrease whereas the X-ray density increases with increasing RE content. It has been found that the value of electrical conductivity also increases with an increase in RE content. The dispersion of dielectric constant has been discussed in the light of Koops model and hopping conduction mechanism.

Abstract

Composite proton conducting non aqueous polymer gel electrolytes have been synthesized by dispersing nano sized fumed silica to the polymer gel electrolytes containing polymethylmethacrylate (PMMA), dimethylacetamide (DMA), benzoic acid (BA) and ortho-hydroxy benzoic acid (o-OHBA). These electrolytes have been characterized by complex impedance spectroscopy, viscosity and pH measurements. The effect of acid, polymer and fumed silica on conductivity, pH and viscosity has been studied for gel electrolytes. Maximum conductivity of 2.95 x 10^-4 S/cm and viscosity of 1.64 x 10⁵ mPas at 25^o C has been obtained. The conductivity of composite gels does not show any appreciable change with time and only a small change in conductivity is observed over the operational range of temperature, which is desirable for their use in device applications.
