Thermal behaviour of alumina precursor obtained by the aluminium sulphate–urea reaction in boiling aqueous solution

Cytotoxicity and apoptotic effects of nickel oxide nanoparticles in cultured HeLa cells.

“…The homogeneous precipitation method in aqueous solution and some physicochemical properties of such oxide powders as Al 2 O 3 and ZnO were investigated in our previous work [17,18] -1 (BET) was obtained by the calcination of the precursors at 500°C for 2 hours. JEOL JEM-transmission electron microscopy (TEM ) images were taken to determine the morphology and dimension of the nanoparticles.…”

Adsorption of Remazol Brilliant Blue R using ZnO fine powder: Equilibrium, kinetic and thermodynamic modeling studies

“…ZnO powders of different shapes, such as spindle-like, rod-like, ellipsoidal, spherical, and prismatic have been synthesized by the one or more of the methods mentioned above [16][17][18][19][20][21][22]. On the other hand, only a few methods were reported in the literature [23] to prepare ZnO powder having flake-like particles.…”

Phase evolution and sintering characteristics of porous mullite ceramics produced from the flyash-Al(OH)3 coating powders

“…Comparing with the XRD patterns in Fig. 3a, it is testified that quartz had partly turned into cristobalite and that corundum (␣-Al 2 O 3 ) had formed from aluminum hydroxide coating through a series of phase changes [21,22]. From 1250 to 1300 • C, the diffraction peak intensities of cristo- balite and corundum become decreased and very weak at 1300 • C. This is because cristobalite, formed in flyash, gradually reacted with ␣-Al 2 O 3 coating to form secondary mullite.…”
