the effect of sonication time (in three levels 0,2,4 min ) and mono- di glyceride (in three levels 0,0.3,0.6 %) on improving the quality of cupcake were studied. color analyze (l*, a*,b*) for dough samples and specific volume, porosity shelf life, color analyze and texture of cake were done. results showed that increasing the levels of each factors (sonication and emulsifier) made a decrease in...

silver-polyaniline (ag-pani) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (aot) solution as an emulsifier. the synthesis of silver-polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (aot), concentration of oxidation agent and c...

Give L an algebraic extension of k(x) where x is an indeterminate, we have defined a lattice Val(L, k) which is a point-free description of the Riemann surface X associated to L/k. (The topology is such that the open correspond to the cofinite sets. Furthermore there is an extra point which corresponds to the trivial valuation ring L.) We present here a fundamental algorithm which of L enumerat...

Droplet-based microfluidic technologies are powerful tools for applications requiring high-throughput, for example, in biochemistry or material sciences. Several systems have been proposed for the high-throughput production of monodisperse emulsions by parallelizing multiple droplet makers. However, these systems have two main limitations: (1) they allow the use of only a single disperse phase;...

The influences of polymerization temperature, initiator and monomer concentrations, ionic strength of the aqueous phase, as well as ethylene glycol dimethacrylate (EGDM) comonomer, on the kinetics of the emulsifier-free emulsion polymerization of methyl methacrylate (MMA) and on the properties of the resulting poly(methy1 methacrylate) (PMMA) lattices were studied. The polymerizations were carr...

Abstract E 472b emulsifiers, defined as lactic acid esters of mono- and diacylglycerides, are food emulsifiers widely used in foamed formulations. So far, only qualitative methods for analyzing have been published. Thus, a new method was developed determining different formulations by high-performance thin-layer chromatography with fluorescence detection (HPTLC‒FLD). The proposed allows simple ...

A Box-Behnken design with three replicates was used for preparation and evaluation of Eudragit vancomycin (VCM) nanoparticles prepared by double emulsion. The purpose of this work was to optimize VCM nanoparticles to improve the physicochemical properties. Nanoparticles were formed by using W1/O/W2 double-emulsion solvent evaporation method using Eudragit RS as a retardant material. Full factor...
