Preparation of spherical FOX-7 particles by using a microemulsion technique has not been reported in the literature. In the present study, the preparation of spherical FOX-7 particles has been described using the novel concept of a micelle-based nanoreactor. Micelle-based nanoreactors have been prepared using a microemulsion of Triton X-100, cyclohexane, and water. Formation of spherical FOX-7 particles in the reverse micelle reactors have been described in the subsequent sections of this article. It is observed that spherical particles of FOX-7 are formed within 2 h in the microemulsion media. Analysis of the experimental results revealed that the particle size and shape of FOX-7 can be varied by changing the water/surfactant molar ratio in the microemulsion. Spherical particles synthesized by this method have diameters that are generally in the submicrometer to nanometer range. Impact sensitivity (h(50)) of the spherical particles obtained by the fall-hammer method is around 45 cm compared to regular synthesized FOX-7 (i.e., 50 +/- 5 cm) without any change in friction sensitivity, i.e. 36 kg. Loadability of the explosive charges can be enhanced by using these spherical particles of FOX-7.</p>1 aMandal, Alok, Kumar1 aThanigaivelan, U.1 aPandey, Raj, Kishore1 aAsthana, Srinandan1 aKhomane, Ramdas, B.1 aKulkarni, Bhaskar, Dattatraya  uhttps://library.ncl.res.in/content/preparation-spherical-particles-11-diamino-22-dinitroethene-fox-7-using-micellar-001767nas a2200253   4500008004100000022001400041245011600055210006900171260007400240300001200314490000700326520086700333653001901200653000901219653002201228653003501250653001201285653000801297653000801305100002101313700002401334700002601358856012901384       2012                        eng d  a0928-070700aSodium-doped lithium zirconate nano squares: synthesis, characterization and applications for CO2 sequestration0 aSodiumdoped lithium zirconate nano squares synthesis characteriz  aVAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDSbSPRINGERcFEB  a316-3200 v613 a<p>Nano squares of sodium-doped lithium zirconate have been synthesized by a simple citrate based sol-gel method at room temperature in the presence of cetyl trimethylammonium bromide (CTAB) as a surfactant.

In this technique contact of air and fuel for combustion is restricted by providing oxygen through oxygen carrier (DC). The functional efficiency of CLC process mainly depends on the ability of oxygen carrier and it's reactivity, which undergoes repeated oxidation and reduction cycles. Nanostructure metal oxides have shown great potential application in the field of chemical looping combustion due to their high surface to volume ratio and enhanced structural properties. Synthesis technique of nanostructure metal oxides, their role as oxygen carrier, their reactivity with fuels along with their structural stability are reviewed herein.
