the effect of ph, different concentration of tween 80 and calcium ion on the stability of limonene-in-water emulsions stabilized by various concentration of sodium caseinate (2, 5 and 10%) was evaluated. to this end, emulsions were prepared by ultrasound and their quality attributes including size distribution, mean diameter of droplets, specific surface area and span number were studied as a r...

In this study chemical method of dissolution-Precipitation was applied to produce amorphous silica nanoparticles from rice straw ash (RSA), the waste material of rice cultivation. The morphology, particle size, structure and area of specific surface of synthesized amorphous silica nanoparticles were evaluated using transmission electron microscopy (TEM), X-ray diffraction analysis (XRD) and BET...
