For the accurate analysis of possible interactive effects of chemicals in a defined mixture, statistical designs are necessary to develop clear and manageable experiments. For instance, factorial designs have been successfully used to detect two-factor interactions. Particularly useful for this purpose are fractionated factorial designs, requiring only a fraction of all possible combinations of...

Green synthesis of silver nanoparticles (AgNPs) involves a reduction reaction metal salt solution mixed with plant extract. The yield can be controlled using several independent factors, such as extract and concentration, temperature, incubation time. AgNPs from Origanum vulgare (oregano) were synthesized in the past. However, no investigations performed on combined effects factors that affect ...

Mixed-level fractional factorial designs are commonly used in industries but its aliasing relations have not been studied in full rigor. These designs take the form of a product array. Aliasing patterns of mixed level factorial designs are discussed here.

The present work is aimed at the optimization of nanosuspension of felodipine, a poorly water soluble antihypertensive drug using Full factorial Design. A 3 Full factorial design using Design Expert Version 8.0.7.1was employed to study the effect of the independent variables (diffusing drug concentration and stabilizer concentration) on the dependent variables (particle size, percentage of drug...

Saline waters treatment has become increasingly important for drinking water supply in a greater part of the world. However, some serious limitations had recently been discovered during water treatment, among them the boron problem seems to have a critical meaning. According to the WHO regulations (2011), the boron concentration should be reduced to less than 2.4 mg/L for drinking water. The pu...
