Synthesis, characterization, conformational equilibrium and intramolecular hydrogen bond analysis of Novel Azocalix[4]arenes including acryloyl moiety using DFT studies
(Elsevier B.V., 2019)
Azocalix[4]arenes were synthesized via diazo-coupling reaction with aniline in 1:1, 1:2, 1:3 and 1:4 molar ratio. Novel Azocalix[4]arenes having Acryloyl moiety were prepared esterification reaction with metallic sodium ...
Effect of heating rate on thermoluminescence characteristics of Y2O3 nanoparticles
(Elsevier B.V., 2019)
The present paper reports the results of heating rate dependencies of thermoluminescence (TL)peaks observed for Y 2 O 3 nanoparticles in the below room temperature region. TL glow curve presented six peaks around 62.5, ...
Temperature lag effect on TL glow peaks: Corrections on kinetic parameters
(Elsevier B.V., 2018)
Analyses on TL glow curves recorded with various heating rates for some ternary and quaternary crystals were accomplished using peak maximum temperatures (Tmax) which are experimentally obtained and corrected according to ...
The effect of austenitizing time on martensite morphologies and magnetic properties of martensite in Fe-24.5%Ni-4.5%Si alloy
(2007)
The effect of austenitizing time on the formation of martensite in Fe-24.5%Ni-4.5%Si alloy has been studied by means of transmission electronmicroscope (TEM), scanning electronmicroscope (SEM) and Mössbauer spectroscopy ...
Investigation of the time evolution of Lane-emden-type Kanai-caldirola oscillator
(2009)
In this study, we have investigated the time evolution of the first kind Lane-Emden-type Kanai-Caldirola oscillator. The total energy of the one dimensional classical harmonic oscillator with time-dependent mass is obtained. ...
Investigation of the time evolutions of some log-periodic oscillators
(2010)
We consider the time evolution of the one dimensional classical and quantum oscillator systems according to its mass and spring constant with fluctuating time. By using the SU(1,1) coherent states, the classical equations ...
