in this research, the effect of different biopolymers such as polyethylene glycol (peg) and polyvinylalcohol (pva) on synthesis and characterization of polymer/cobalt ferrite (cf) nano-composites bymechanical alloying method has been systematically investigated. the structural, morphological andmagnetic properties changes during mechanical milling were investigated by x-ray diffraction (xrd),fo...

kefiran is an exopolysaccharide produced by microorganisms present in the kefir grains that has several health promoting properties. in this research, physico-mechanical and thermal characteristics of nanocomposite film composed of kefiran-montmorillonite (mmt; 1, 3 and 5% w/w) were studied. results showed that the thickness and the tensile strength of the films increased by increasing the nano...

Nanoparticles are being utilized in agriculture as fertilizers, pesticides, and agrochemical-carriers. Designed to be biocompatible degradable, biopolymer nanoparticles were developed an alternative metallic nanoparticles, though safe-by-design, polymeric must field-tested prior largescale use. Several field studies conducted observe detrimental effects of on plant growth yield using soybean, G...

This paper focused on the short review of biopolymer based composite for tissue regeneration. Biopolymers have been slowly introduced into medical applications as a result their ability to be bio-degradable and easily made. By selecting appropriate containing selected additives facilitate polymer-filler interaction, composites with desired properties can obtained. Interfacial interactions betwe...

the effects of chitosan/biopolymer (c/p) and nanohydroxyapatite/ biopolymer (nha/p) weight ratios on particle size and its uniformity, cross-linking density and nh2 content of nano-hydroxyapatite/chitosan/gelatin (nha/c/g) microspheres were investigated. microspheres were fabricated using water-in-oil emulsion. cross-linking of microspheres was performed using water soluble carbodiimide. partic...

biopolymer based nano-complex is a category of nano-carriers which are produced by interaction between protein and polysaccharide. they can carry hydrophobic nutriciuticals in aqueous solutions and also cause to increase of protection and bioavailability of encapsulated active materials. in this research, gellan-caseinate complexes containing omega3 were produced by adding gellan solutions to c...

in this paper effect of sio 2 nanoparticles was investigated on potato starch films. potato starch films were prepared by casting method with addition of nano-silicon dioxide and a mixture of sorbitol/glycerol (weight ratio of 3 to 1) as plasticizers. sio 2 nanoparticles incorporated to the potato starch films at different concentrations 0, 1, 2, 3, and 5% of total solid, and the films were dri...

In order to investigate chitosan and magnesium-nano fertilizers’ impact on photosynthetic pigments, protein, proline, and soluble sugar contents of sesame under irrigation cut-off treatment, a split-factorial experiment was conducted based on randomized blocks with three replications. Irrigation cut-off based on BBCH sca...
