Due to the fact that many application processes take place at different temperature, better examining and understanding of swelling properties as a function of temperature is essential for such application. The temperature effect on the swelling properties of commercial polyacrylic acid (PAA) hydrogel beads was investigated as a function of time and temperature. Gel bead size, swelling equilibr...

Enzymatic modification of foods is an important tool for enhancing starch functionality due to its safety, high efficiency, and specificity. gelatinized systems well reported in literature. However, our knowledge, a review describing comparing the effects granular vs. enzyme-assisted both timely lacking. We summarize, discuss point at future aspects consequences using various techniques enzymat...

semelil is an herbal-based compound which is used for the treatment of chronic wounds, especially diabetic foot ulcers. on the other hand, electrospun nanofibers have many characteristics such as mimicking extracellular matrix structure, efficiency as bacterial barrier, appropriate water vapor transmission rate, and provision of adequate gaseous exchange which make them ideal candidates for wou...

leishmania antigens are weak immunogens and need to be potentiated by various adjuvants and delivery systems. alginate microspheres as an antigen delivery system and quillaja saponins (qs) as an immunoadjuvant have been used to enhance the immune response against autoclaved leishmania major (alm). microspheres were prepared by an emulsification technique and characterized for size, encapsulatio...

expansive behavior is usually observed in soils, which contain fractions of clay minerals in their composition. water absorption of clay particles and change of natural water content of soil up to plastic limit and down to shrinkage limit will cause significant volume change in expansive soils and will result in severe damages to the structures, buildings and foundations. swelling potential is ...

cotton fibres were subjected to cleaning process and then characterized for maturity. decrystallisation and swelling processes with caustic soda, ethanol, propan-2-ol and trichloroethene on the native fibres were carried out. the effects of these on the strength and moisture regain were investigated. the activation energies of the dyeings were also analysed with durazol scarlet red 4 bas. the r...

using controlled drug delivery devices is one of the novel methods of drug delivery which is used to perform drug therapy with the minimum side effects. mucoadhesive polymers are one of these devices. chitosan is a natural polymer which is a suitable candidate for this purpose due to it is biocompatibility, bioadhesion and high capability to adsorb peptide drugs. since gi tract has both acidic ...

introduction: hydatid disease caused by larval stage of echinococcus has been recognized endemically in many countries. liver and lungs are the most commonly affected organs. involvement of the head and neck region is rare and bony erosion due to hydatidosis is even rarer. case report: we report a case of a 17-year-old girl from a poor socio-economic background who presented with a right sided ...

A carboxymethyl cellulose (CMC)/polyethyleneimine (PEI) hybrid hydrogel was successfully prepared under green processing conditions. The CMC and PEI formed a polyelectrolyte complex, the three-dimensional (3D) network structure hardened by chemical crosslinking, resulting in suitable properties. In CMC/PEI hydrogel, surface charge easily switched according to pH change, swelling contraction rev...
