New bionanocomposite proton exchange membranes were prepared from sulfonated polybenzimidazole (s-PBI) and various amounts of sulfonated ZnO/cellulose nanohybrids (ZnO/cellulose-SO3H). The use of ZnO/cellulose-SO3H compensates for the decrease in ion exchange capacity of membranes observed when non-sulfonated nano-fillers are utilized. The strong –SO3H/–SO<su...

ABSTRACT: The use of new compounds to increase the shelf life of more perishable foods based on nanoparticles and biodegradable polymers have been developed in packaging. Chitosan (Cts) is a natural biopolymer with excellent biodegradability and nontoxicity and antibacterial effect. In this research antibacterial copper nanoparticles (CuNPs) were incorporated in the biodegradable chitosan matri...

Objective(s): Fabrication of scaffolds with improved mechanical properties and favorable cellular compatibility is crucial for many tissue engineering applications. This study was aimed to improve mechanical and biological properties of polycaprolactone (PCL), which is a common biocompatible and biodegradable synthetic polymer in tissue engineering. Nanofibrillated chitosan (NC) was used as a n...

Chitin and chitosan have versatile biological activities and chemical applications and as such have been found to be immensely popular as biomedical addictives. F.solani CBNR KKRR, isolated from the marine soils of Pichavaram, Tamil Nadu was used for the economic production of Chitin and Chitosan using three different media-Sabouraud sucrose broth, Hesseltine and Anderson medium, Andrade et al ...

BACKGROUND The search for promising and renewable sources of carbohydrates for the production of biofuels and other biorenewables has been stimulated by an increase in global energy demand in the face of growing concern over greenhouse gas emissions and fuel security. In particular, interest has focused on non-food lignocellulosic biomass as a potential source of abundant and sustainable feedst...

the objective of this research was to compare the tensile, permeability, solubility and color properties of plasticized starch-polyvinyl alcohol-montmo-rillonite (ps-pva-mmt) and plasticized starch-polyvinyl alcohol-cellulose nanocrystal (ps-pva-ncc) bionanocomposite flms. the results showed that adding mmt (7%), increased the ultimate tensile strenght from 4.2 mpa to 4.61 mpa, however, ncc (7%...

introduction: biodegradable films for food packaging applications have attracted an increasing amount of consideration over the last two decades, predominantly due to environmental pollution and the realization that our petroleum resources are not infinite. starch, which is one of the natural biopolymers, has been considered as one of the best candidates primarily because of its processbility, ...

Functionalized single-wall carbon nanotubes (f-SWCN) are dispersed in chitosan films by self-assembly of both components aqueous media. This form is a promising nanofiller to achieve nanocomposites with refined thermal, mechanical and surface features. In this study, we investigated the influence functionalized concentration on resulting properties structures. molecular scale polymeric matrix d...
