“…The functional properties can be tuned by modifying the size, shape and composition of the synthon along by studying state of art of the synthetic method with pH control which helps to design a device for their technological applications with synergic effects to control the nucleation and its growth. Understanding the nucleation and growth process by self-assembling helps to integrate functional structures via optimizing hydrolysis and kinetic process based on electro-negativity of metal ion (Klein 1988;Brinker and Scherer 1990;Sakka 2004;Szafert et al 2008;Grado-Caffaro 2008;Bilecka and Niederberger 2010;Bang and Suslick 2010;Liu et al 2011;Hassan et al 2012;Precht and Campbel 2013;An and Soorrjai 2015).…”

Well-defined structural framework of ZrSnO 4 nanopowder has been synthesized for the fabrications of cost-effective and sensitive devices which give final reproducible result with reliability under ideal conditions. The synthesis was carried out at moderate temperature and then finally dried in the laboratory oven and then followed with calcination at 1000°C for 4 h to get phase selective product. It was observed that gelation time depends on the concentration of reactants and temperature. The characterization of ZrSnO 4 was carried out with XRD, SEM, TEM, UV, thermal analysis, DLS and FT-IR techniques. With adjustment of reaction parameters, the systematic tuning of the particle size, shape and functional properties can be controlled. It was concluded that self-assembly is an integral part for the synthesis and opens a new exciting opportunity for better understanding the formation of nanostructure framework from micro-to nanoscale along with mechanistic via wet chemical approach. ZrSnO 4 has vital role in identifying its potential cytotoxicity in the biological systems. The cytotoxicity effects of ZrSnO 4 nanopowder in vitro were evaluated in three different human cell types (hepatocytes, mesenchymal stem cells and neuronal cells). Acute exposure of nanoparticles was found to have greater cytotoxic effect at higher concentration (30 lg/ml). However, partial detoxification was observed during nanoparticles exposure at day 6. The study concluded that an initial stress from nanoparticles incorporates sealing or detoxification of nanoparticles which may help to recover cell viability.

“…But evidences have shown that the band gap of CdO can also vary in the range of 1.1 to 3.3 eV [7], [8]. This drastic change in band gap is considered as lattice's defects that arise as a result of Burstein-Moss effect [9]. Nanoparticles of Transition-metal oxides have heightened optical, magnetic and electrical properties rather than their bulk equivalents, thus setting them for a large number of interesting applications.…”

Undoped CdO, Mn3O4 and CdO - Mn3O4 doped nanocomposites in the ratio 9:1, 8:2, 7:3 and 6:4 were successfully synthesized through thermal decomposition at high temperature by adopting the method of solid state reaction. powder X-ray diffraction (PXRD) was employed to carry out the structural characterization. It was found that as the concentration of Mn3O4 was increased the size of the prepared CdO-Mn3O4 composites has decreased. The change of various dielectric variables like dielectric loss (tanδ), dielectric constant (εr ) was determined. Moreover the change of ac conductivity (σac) with respect to frequency was carried out using LCR meter. It was found that these dielectric parameters have increased with respect to the temperature. It was also found that, with an increase in temperature the dc conductivity measurements for the prepared nano composites have also increased

“…Perhaps the most known application of CdO is as transparent contact in solar cells and as antireflection coating. On the other hand, we have to mention that this oxide has been investigated experimentally with quite satisfactory results [1][2][3][4][5][6][7][8][9][10][11][12] and by elaborating successfully theoretical-analytical approaches [13][14][15][16][17]. But, unfortunately, some works as, for instance, Refs.…”
