The influence of the particle size on magnetic behaviors of nickeloxide nanoparticles (NiO NPs) was reported. NiO NPs with a uniform particlesize were synthesized via a facile sol-gel method, and various sizes of NiO NPs(11, to 49 nm) were achieved by calcination at various temperatures (400, to 700°C). X-ray diffraction (XRD) analysis revealed that increasing the calcinationtemperature increas...

Liposomes were prepared by stepwise extrusion through 5, 1, 0.4, 0.2, 0.1 and 0.05 microm pore sizes using two different filter-extruders, the continuous high pressure device Dispex Maximator (CE) or alternatively the discontinuous Avestin LiposoFast (DE). The liposome dispersions obtained were compared in terms of particle size, lamellarity and encapsulation efficiency of calcein. The liposome...

An attempt has been made in this paper to investigate the effect of particle size distribution on coal flotation kinetics. The effect of particle size (Ps) on kinetics constant (k) and maximum theoretical flotation recovery (RI) was investigated while other operational parameters were kept constant. The relationship between flotation kinetics constant and theoretical flotation recovery with par...

in this study, isophthalic acid-zirconium(iv) nanocomposite has been prepared from zirconyl nitrate pentahydrate and potassium iodide, with isophthalic acid, (c8h6o4=benzene-1,3-dicarboxylic acid) as a ligand, via sonochemical method in ethylene glycol and methanol as solvents. the crystalline tetragonal zro2 has been produced by thermal decomposition of isophthalic acid-zirconium(iv) nanocompo...
