Water Absorption of Chitosan, Collagen and Chitosan/Collagen Blend Membranes Exposed to Gamma-ray Irradiation
TThis study investigated the water absorption of chitosan, collagen, and chitosan/collagen blend membranes exposed to gamma-ray irradiation. These membranes were produced via the solvent evaporation method. All membranes then underwent irradiation at 15 or 25 kGy gamma-ray doses, while membranes without irradiation were used as controls. After immersing the membranes in distilled water for up t...
متن کاملGamma Ray Irradiation for Crop Protection Against Salt Stress
Legumes have tremendous dietary value for human nutrition. However, the productivity of food legumes is always compromised owing to their insufficient ability to tolerate abiotic stresses such as drought or water logging, marginal soil, low/high temperatures and salt stress. Stress induces changes at the morphological, physiological, biochemical and molecular level which are consequently manife...
متن کاملMorphological mutants of St. Augustinegrass induced by gamma ray irradiation
St. Augustinegrass is a widely used turf and pasture grass in the southern US. Raleigh is a cultivar known for superior cold tolerance than other St. Augustinegrass cultivars. However, its coarse-leaf texture and long internodes are undesirable when planted in home lawns. Mutagenesis by gamma ray irradiation was employed to treat node cuttings and calli for inducing semi-dwarf growth phenotype....
متن کاملFunctionalizing Graphene Oxide with Alkylamine by Gamma-ray Irradiation Method
A gamma-ray irradiation technique was used to functionalize graphene oxide (GO) with alkylamines of various alkyl chain lengths. Functionalization of the alkyl chains onto the GO was confirmed by nuclear magnetic resonance (¹H NMR), Fourier transform infrared (FTIR), and X-ray diffraction (XRD). FTIR of the functionalized GO showed the appearance of significant peaks around 2960-2850 cm-1 (-CH₂...
متن کاملSimulation of gamma-ray gamma rays by composite shields compared to the lead protection using the MCNPX code
In this study, cobalt 60 with a mean energy of (1.25 Mev) was used as a photonic source to investigate the effect of decreasing gamma-ray intensity by materials and polymer composite using MCNPX code. First, we investigated the effect of thickness and density on the reduction of gamma ray intensity, and then the comparison between the lead protector, tungsten and polymer composite in several th...
