For more characterization of the prepared silver nanoparticles, two drops of the silver nanoparticles colloidal solutions were placed on a 400 mesh copper grid coated by carbon film and then the grids was conducted to the morphology and the distribution of AgNPs were characterized by means of a JEOL-JEM-1200 transmission electron microscope.
From Figure 3 which shows the UV-Vis spectra of the colloidal solutions of nanosilver prepared by different concentrations of maize starch, it could be clarified that, from Figures 3(a) and 3(b) showing the spectra of 1 g/L and 3 g/L of maize starch, the absorbance was increased with time till it reached the maximum value at 60 minutes (1.
Figure 3(d) shows the comparable UV-Vis spectra of the silver colloidal solutions obtained using different concentrations of maize starch as reducing and stabilizing agent.
Increased microvascular permeability to albumin and protein macromolecules has been extensively documented and underlies the concern theat colloidal solutions may be harmful or ineffective in clinical disorders.
13 per life saved as compared with using colloidal solutions at a cost of $1493.
Modified starches are insoluble in cold water (if not pregelatinized) and form typical colloidal solutions with viscous properties in hot water.
It is insoluble in cold water (if not pregelatinized) and forms typical colloidal solutions with viscous properties in hot water.
The candidate proposes computational research of the sedimentation dynamics of confined colloidal solutions as well as the dynamics and optics of liquid crystals in microfluidics ("optofluidics").
The intense color of colloidal solutions makes it possible to determine negligible amounts of the dispersed phase of a colloid.
