The Grüneisen Parameter and Higher Order Thermo Elastic Properties of Fe, Co at Higher Pressures
Team IJTSRD
June 02, 2020
0
Expressions have been obtained for the higher order Thermo elastic properties of the Grüneisen parameter in the limit of infinite pressure The usefulness of these expressions has been demonstrated by considering a relationship between reciprocal Grüneisen parameter and the pressure bulk modulus ratio at finite pressure. The results have been obtained using...

Pressure Dependent of Melting Temperature for MgO and Hcp Iron
Team IJTSRD
June 01, 2020
0
The Volume dependence of the Grüneisen parameter has been used to calculate the pressure dependence of melting temperature for MgO and hcp iron using Lindemann law. The Volume dependence of the Grüneisen Parameter has been determined using gamma volume V relationship due to Al'tshuler and reciprocal gamma volume V relationship due to Srivastava et al. The...

Optical Response of MoSe2 Crystals
Solar power is a very important source of renewable energy for many low power systems. Matching the power consumption level with the supply level can make a great difference in the efficiency of power utilization. MoSe2, crystals (photo-electrodes) have been grown via a direct vapour transport technique. This paper presents results of Photo Voltage (VPh) Vs....

FTIR Spectra of Ni (H-dmg)2 Hydrogen Bonded With Six Dyes
Here the one-dimensional semiconductor namely bis (dimethyiglyoximato) Ni?? is hydrogen bonded with 6 highly polarizable dyes which are Para red, Congo red, Direct red, Bismark brown, Evans blue and Trypan blue. The hydrogen bonding was verified with FTIR spectroscopy. FTIR specra also reveal modification of absorption edges by exciton-phonon coupling there...

FTIR Spectra of Magnetic Charge Transfer Complexes of TEMPO Free Radical
The Fourier '“ transform infrared spectra of complexes of TEMPO free radical with organic acceptors like TCNE, DDQ, TCNQ, Chloranil has been studied. Some of them have ferro or antiferromagnetic properties at very low temperatures. From FTIR spectra, these complexes are found to be small band-gap semiconductors. They are interpreted as Hubbard semiconductors...

Spectroscopic Study of Electronically - Doped Polyanilines
Polyanilines namely emeraldine, nigraniline and pernigraniline were prepared by chemical method and were electronically-doped with organic acceptors such as, TCNE, TCNQ, DDQ, Chloranil and KI-I2. The FTIR spectra of 20% and 50% doped polyanilines were obtained and analyzed using small polaron model which connected electrical conductivity with IR absorption....
