Synthesis of LiMn2O4 by glycine-nitrate method
(Journal of Optoelectronics and Advanced Materials, 2003)
Glycine-nitrate method was used to synthesize lithium manganese oxides. For the molar ratio of lithium-to-manganese in precursor solution equal to 1:2 spinel LiMn2O4 was obtained. For molar ratio of 1:1 a mixture of Li2MnO3 ...
Luminescent properties of nano-SiO2 : Eu3+/polypropylene composite
(Journal of Optoelectronics and Advanced Materials, 2006)
In this paper the luminescent properties of a composite made from isotactic polypropylene and silicate nanopowder doped with trivalent europium ion were investigated. The method for obtaining the investigated composite is ...
Endohedral fullerenes of different elements
(Journal of Optoelectronics and Advanced Materials, 2006)
In this work we have studied the Li/C-60, Li/C-70, (99)mTc/C-60, (TC)-T-99/C-70, Gd/C-60, Gd/C-70, Nd/C-60, Nd/C-70, Y/C-60 and Y/C-70 systems by surface ionization mass spectrometry and investigated a possibility of the ...
Methods of purification and characterization of carbon nanotubes
(Journal of Optoelectronics and Advanced Materials, 2006)
In an attempt to purify MWNT in mild conditions, we have applied two different methods of purification. The first method of purifying the material was a combination of relatively often used methods, such as etching and ...
Influence of electrode material on gas-filled surge arresters characteristics in gamma and X radiation field
(Journal of Optoelectronics and Advanced Materials, 2006)
The aim of this paper is to find the possibility for improvement of gas-filled surge arresters (GFSA) characteristics in y and X radiation field by appropriate choice of electrode materials. For that purpose electrodes ...
