The influence of important physical data of the two-phase system (interfacial tension, viscosities), of the polymerization conditions (stirring or reaction time, stirrer speed, phase ratio, concentration of initiator), and of the geometry of the reactor (stirrer type, tank diameter) on the main particle size and the particle size distribution of the polymer were determined experimentally.
Figure 12 presents the main effect of particle size.
The results indicate that Fe2+/Fe3+ ratio and pH are the main factors affecting particle size and specific saturation magnetization, respectively.
However, in dispersions under study (NaCl 0.1 M) in the range from pH of 7 to 11, the main mode in particle size distribution curve shifts toward lower hydrodynamic particle size, indicating increased repulsion between nanotube aggregates.
Results indicated that homogenization pressure was the main contributing variable for particle size.
The main characteristics envisaged are particle size distribution, roundness and sphericity, density, specific gravity, bulk density, turbidity, crush resistance, single particle compression test, and fracture conductivity.
Moreover the main fraction of the particle size (60% of the fraction 3.15 ≤ P ≤ 45 mm) reached 79.2% with the HELK compared with the 67.9% with the HSK.
Additionally, for the polishing environment, the main factors include the particle size and viscosity of polishing paste and polishing liquid, the temperature and pressure during polishing and the chemical correction of part in the polishing liquid.
The results indicated that the speed of homogenization was the main contributing variable for particle size; while, in the case of entrapment efficiency, the drug concentration showed the major role.
In this work, the preparation conditions are same for bulk-Fe2O3 PEG400 bulk-Fe2O3 PEG400-PEG400 nanofluid; the two mand differences are the particle size of Fe2O3 in these fluids and interaction of PEG with the surface of γ-Fe2O3-PEG400rtheles which can be higher twon the surface of bulk-Fe2O3.
The results in this study revealed that sonication time has the main effect in determining both particle size and entrapment efficiency of liposomal formulations.
