  • Dielectric relaxation in Se₈₀Ge₂₀ and Se₇₅Ge₂₀Ag₅ chalcogenide glasses 
    Dwivedi, A.; Arora, R.; Mehta, N.; Choudhary, N.; Kumar, A. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2005)
    Temperature and frequency dependence of dielectric constant (ε') and dielectric loss (ε") are studied in glassy Se₈₀Ge₂₀ and Se₇₅Ge₂₀Ag₅. The measurements have been made in the frequency range (1 to 10 kHz) and in the ...
  • Reduction of WO₃ to WC nanoparticles by reflux reaction₃ 
    Kumar, R.; Kumar, A.; Singh, S.; Pandey, O.P. (Фізико-хімічна механіка матеріалів, 2013)
    WC is an important material mostly used for cutting tool application. Reduction of WO₃ to WC is being done by several techniques. The existing chemical processes involved in its reduction are long and energy consuming. ...
