Gamma irradiation processing of hydroxyapatite/poly-L-lactide composite biomaterial
(Radiation Physics and Chemistry, 2003)
Effects of gamma irradiation on structure and physicochemical properties of the hydroxyapatite/poly-L-lactide (HAp/PLLA) composite were studied in this paper. Since the morphology of HAp/PLLA is very sensitive to gamma ...
Radiation-induced degradation of hydroxyapatite/poly L-lactide composite biomaterial
(Radiation Physics and Chemistry, 2007)
The effects of gamma irradiation on the structure and properties of hydroxyapatite/poly L-lactide (HAp/PLLA) biomaterial have been investigated. Effects of radiation on microstructure, degradation of polymer part and thermal ...
Effect of gamma irradiation on magnesium content in rat tissues
(Magnesium Research, 2003)
Studies in the field of radiation chemistry have shown that the greatest damage induced by ionizing radiation appears as a consequence of uncontrolled production of free radicals in the living organism, which have their ...
Gamma radiation effects on mechanical properties of carbon/epoxy composites
(Materials Science Forum, 2006)
Unidirectional and angle-ply carbon/epoxy laminates were gamma irradiated up to doses of 12 and 20 MGy. Composites with two different, low and high temperature epoxy matrices have been submitted to irradiation and subsequent ...
Thermal and crystallization behaviour of gamma irradiated PLLA
(Radiation Physics and Chemistry, 2007)
Structure, crystallization behaviour and some thermal properties of poly-L-lactide (PLLA), gamma irradiated up to 300 kGy, have been studied. Through differential scanning calorimetry measurements, radiation-induced changes ...
Delamination strain energy release rate in carbon fiber/epoxy resin composites
(Materials Science Forum, 2007)
The paper reports on an experimental study of the Mode I interlaminar fracture of unidirectional carbon fibers/epoxy resin composites. Mode I delamination strain energy release rate G(IC) was determined in double cantilever ...
Do altered activities of superoxide dismutases and the level of NF-κB modulate the effects of gamma radiation in HeLaS3 cells?
(Journal of the Serbian Chemical Society, 2007)
Most experimental models, including cell culture studies, have demonstrated that over-expression of manganese superoxide dismutase (MnSOD) in cells bearing a carcinoma phenotype has anti-proliferative and tumour suppression ...
Swelling and thermodynamic studies of temperature responsive 2-hydroxyethyl methacrylate/itaconic acid copolymeric hydrogels prepared via gamma radiation
(Radiation Physics and Chemistry, 2007)
The copolymeric hydrogels based on 2-hydroxyethyl methacrylate (HEMA) and itaconic acid (IA) were synthesized by gamma radiation induced radical polymerization. Swelling and thermodynamic properties of PHEMA and copolymeric ...
Radiolytic synthesis of Ag-poly(BIS-co-HEMA-co-IA) nanocomposites
(Radiation Physics and Chemistry, 2007)
Ag-poy(BIS-co-HEMA-co-IA) nanocomposites are prepared via in situ reduction of silver salt embedded in swollen polymer gels by employing gamma irradiation. Hydrogels based on 2-hydroxyethyl methacrylate, itaconic acid and ...
Effects of charge trapping in gamma irradiated and accelerated aged low-density polyethylene
(Polymer Degradation and Stability, 2006)
The effects of gamma irradiation in air and accelerated aging of low-density polyethylene (LDPE) were studied through dielectric loss (tan 6) analysis in the temperature range from 25 to 325 K and using thermally stimulated ...
