in this research, gelatin nanoparticles were synthesized via inverse miniemulsion method by employing a mixture of a water soluble carbodiimide (cdi) and n-hydroxysuccinimide (nhs) as a non-toxic cross-linking system. the gelatin nanoparticles were characterized for their size and size distribution, morphology and stability and were compared with those of nanoparticles cross-linked by glutarald...

the studies report the synthesis of novel graft copolymer of oatmeal. polymethyl methacrylate grafting was carried out on oatmeal backbone via ‘microwave assisted’ approach. the graft copolymers were optimized by varying monomer and can concentration. the synthesized graft copolymers were characterized by intrinsic viscosity, ftir, tga, sem, elemental analysis, number average molecular weight a...

With rheology progress was made in understanding of structure of gels and colloidal suspensions, particularly with regard to polysaccharides and large glyconjugates. Whereas the rheology of concentrated dispersions is the considerable interest to the colloidal scientist, pharmacist or food technologist [1], of more interest to molecular biophysicist is dilute solution viscometry and the structu...

Yu S., Xu J., Zhang Y., Kopparapu N.K. (2014): Relationship between intrinsic viscosity, thermal, and retrogradation properties of amylose and amylopectin. Czech J. Food Sci., 32: 514–520. The relationships between intrinsic viscosity and some properties of amylose and amylopectin were investigated. The intrinsic viscosities determined by Ubbelohde viscometer for rice, maize, wrinkled pea and p...

2014 Intrinsic viscosity measurements have been performed on polystyrene-cyclohexane system as a function of temperature T (T ~ 03B8 and as a function of molecular weight (8.2 x 104 ~ Mw ~ 2.06 x 107) .The expansion factor 03B13~ = [~]/[~03B8] of the intrinsic viscosity [~] scales with the reduced variable (T 2014 03B8/T) · ~Mw. For (T201403B8/T) ” ~Mw ~ 2014 40, the intrinsic viscosity of a co...
