Synthesis and characterization of nanocrystalline LiNi0.5Co0.5VO4 powders by citric acid assisted sol–gel combustion process

“…In these compounds, an enhanced electrochemical performance was observed for the composition of LiNi 0.5 Co 0.5 VO 4 [8,9]. Since, the crystallite size of cathode powders plays major role in electrochemical properties, synthesis of LiNi 0.5 Co 0.5 VO 4 powders in nanosize is an important task for their enhanced electrochemical performance [10][11][12]. Synthesis of LiNi 0.5 Co 0.5 VO 4 powders by solid-state reaction method exhibits disadvantages such as bigger crystallite * Corresponding author.…”

Quantum Size Effects in the Photonics of Semiconductor Nanoparticles

“…Most of the publications have been concerned with methods for the synthesis of nanoparticles [13], determination of their optical and electrophysical characteristics, and study of the photophysical and primary photochemical processes [1-4, [10][11][12][13][14][15][16][17][18][19][23][24][25][26][27]. Significantly less attention has been paid to photocatalytic and photoelectrochemical processes, and very little attention has been paid to processes and characteristics in nanomaterials not associated with the action of light (adsorption, catalytic, etc.).…”

“…Semiconductor nanoparticles are some of the most interesting and intriguing subjects of modern developments in physics [1][2][3][4][5][6][7][8][9], chemistry [1, 4, [10][11][12][13][14][15][16][17][18][19][20][21], biology [22], materials science [3,23,24], and technology [8,9,[24][25][26], as shown by the rapid increase in the number of publications devoted to their production and investigation. The interest of research workers in semiconductor nanoparticles (SC NP) is due primarily to their special thermodynamic, photo-and electrophysical, magnetic, and photochemical characteristics, which sometimes differ greatly from the characteristics of the same substances existing not only in the macrocrystalline but also in the microcrystalline state.…”

Electrochemistry with Nanoparticles

“…A large number of theoretical and experimental studies have been carried out to understand the basic characteristics of the optical, electronic, chemical and mechanical properties of metallic nanoparticles [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Mie has made seminal contributions to quantitatively correlate the changes in the optical properties with the variation in the size of the particles [2].…”

“…The effects of size on diffusion kinetics, electrical double layer at the interface, elementary act of charge transfer and phase formation have recently been reviewed by Petrri and Tsirlina [12]. Mulvaney has given an excellent account of the double layers, optical and electrochemical properties associated with metal colloids [11].…”
