Volume 3, Issue 3 , 2018, , Pages 146-150

https://doi.org/10.5185/amp.2018/986

Abstract
  The dielectric constant (ε') and dielectric loss (ε״) of pristine and C5+ (70 MeV) ion irradiated samples of the PEEK have been investigated with the variation of temperature at different frequencies (100 Hz, 1 kHz, 10 kHz and 100 kHz). The maxima are obtained around 170 oC in dielectric ...  Read More

Volume 2, Issue 5 , 2017, , Pages 310-314

https://doi.org/10.5185/amp.2017/506

Abstract
  Li-Ni-Co ferrite/SiO2 composites with representative formula Li0.41Ni0.1Co0.08Fe2.41O4+ xSiO2 (i.e., x = 0wt. %, 5wt. %,10wt. % and 20wt. %) were prepared by sol-gel method. The prepared composites were pre-sintered at 600ºC for 2 hrs and then finally sintered at 1000ºC for 6 hrs. X-ray diffraction ...  Read More

Volume 1, Issue 1 , 2016, , Pages 114-117

https://doi.org/10.5185/amp.2016/120

Abstract
  SiO2 nanoparticles of average size 15-20 nm have been synthesized and its dielectric properties have been investigated as a function of frequency (between 20 Hz to 2 MHz). A very high dielectric constant of ca. 14000 at 20 Hz and at room temperature has been observed which is very high compared to the ...  Read More
