Tested variables include the methanol to oil ratio, concentration of catalysts, reaction time and reaction temperature.
Table 3 illustrates that the ion exchange capacity of CA/TPC was influenced by mixing ratio, concentration of reagents and system pH.
The effects of the phosphatidylcholine-to-cholesterol ratio, concentration of EGCG and Tween 80, and rotary evaporation temperature on preparing EGCG nanoliposomes were studied.
A response surface experimental design with four factors was analysed: casein:whey-protein ratio, concentration of carrageenan, KCl and CaCl2 addition to the milk system.
The influence of drug polymer ratio, concentration of surfactant in the aqueous phase on particle size, drug entrapment efficiency (EE) % and in vitro drug releases were investigated.
Advanced poly o-toluidine)@Sn II)silicate/CNT nanocomposites were synthesized using sol gel of Sn II) silicate by varying the mixing volume ratio concentration of inorganic reactant with a fixed mixing volume ratio, i.e., 1 1, of organic polymer.
Reaction parameters (monomers/salep ratio, concentration of reactants, MAPTAC/AM ratio, and APS) were optimized using a full factorial experimental design to obtain the highest settling rate for cement suspensions.
Although analytical error in the field of mass spectrometry is commonly expressed as parts per million (ppm) [6], mass accuracy can be significantly affected by mass to charge ratio, concentration of the compound, and the amounts of co-eluting metabolites.
For measuring atRA release from hydrogel disks, a higher molar ratio concentration of 8 1 (atRA BSA) was used when incorporating atRA into BSA precursor solutions before gelation.
