solubility of high molecular weight n-paraffins in supercritical carbon dioxide has been a matter of interest to many researchers. however, not sufficient solubility experimental data are available although the methods by which the experimental data are obtained have many varieties. utilizing cubic equations of state is an effective method for solubility prediction of n-paraffins in supercritic...

during last two decades, polysaccharides such as alginate (alg) alone and in combination with other biopolymers are widely used in vaccine and drug delivery systems. the aim of the present work was to investigate the potential utility of microparticles made of alginate (alg) as new vehicles for improving nasal vaccine delivery. for this purpose, diphtheria toxoid (dt) was chosen as a model anti...

a mixture  of  sodium  lauryl  sulfate  (sls)  as  ionic  emulsifer  and  stearyl alcohol as non-ionic emulsifer was employed in a vinyl chloride emulsion polymerization  reaction  to  study  the  infuence  of  various  interactive parameters involved in the reaction system. it was found that the particle size was dependent on the amount and type of emulsifer. the average particle size of polyv...

the molecular weight distribution of 4 commercial isotactic polypropylene (ipp) samples was estimated using rheological data. the dynamic moduli data, obtained from rheological measurements in linear viscoelastic region was used for calculation of relaxation time spectrum, h(τ) and then shear relaxation modulus, g(t). finally, applying thimm kernel function and relaxation modulus data in genera...

low molecular weight heparin-modified isoliquiritigenin-loaded solid lipid nanoparticle (lmwh-isl-sln) was developed for injective application. the morphological observation, particle diameter and zeta potential of lmwh-isl-sln were characterized using transmission electron microscopy (tem) and a malvern zetasizer. its entrapment efficiency (ee) and drug loading (dl) were determined by ultracen...
