Radiation processing of materials for a variety of applications has been well-established, and is also continuing to evolve further. The cost of radiation treatment, that is, say, dollar per kGy per kg, is dependent on several factors of the radiation facility and operations, and almost always irrespective of the nature of material being treated. Consequently, materials of higher value like...

RADIATION SYNTHESIS AND MODIFICATION OF MATERIALS
Oral
The mainstream of radiation modifications of polysaccharides was limited to reduction of molecular weight due to main-chain degradation in order to facilitate further processing or induce specific biological activities. On the other hand, graft polymerization of functional monomers initiated through radicals crated by ionizing radiation on polysaccharide chains, or as effect of glycosidic...

MITIGATING THE IMPACT OF CLIMATE CHANGE -07
Oral
Pollution of soil by heavy hydrocarbons (HH, C12-C40) is a major global environmental issue. Heavy hydrocarbons pose a significant remediation challenge because they are recalcitrant and relatively immobile in soils, and hence will persist in the environment for a long time. Electron beam has the potential to both crack and polymerize hydrocarbons at lower temperatures than similar energetic...

RADIATION SYNTHESIS AND MODIFICATION OF MATERIALS
Oral
Background:
Cellulose is the major structural component of wood and plant fibers and is the most abundant polymer synthesized by nature. Despite this great abundance, cellulosic biomass has seen limited application outside of the paper industry. Its use as a feedstock for fuels and chemicals has been limited because of its highly crystalline structure, inaccessible morphology and limited...

RADIATION SYNTHESIS AND MODIFICATION OF MATERIALS

Cassava starch (CS) is a natural polymer that is inexpensive and abundant, especially in Thailand. In addition to being cost-effective, CS is also biodegradable, compostable, non-toxic and most importantly renewable. Consequently, blending CS with other biodegradable synthetic polyester such as poly(lactic acid) (PLA) is economically interesting, due to a high potential of cost reduction as...

Reduction of graphene oxide (GO) in ethanol/water solution in the presence of oxygen by γ–ray irradiation was studied. Suspension of GO was prepared by dispering graphite oxide in the ethanol/water solution at a concentration of about 1 mg/ml under ultrasonic condition, and then irradiated by γ–rays in an absorbed dose range of 0 – 250 kGy. The characteristic properties of GO and reduced GO...

RADIATION SYNTHESIS AND MODIFICATION OF MATERIALS
Oral
Ultra-high molecular weight polyethylene (UHMWPE) has excellent chemical inertness, biocompatibility, mechanical property and wear-resistance, which is widely used in engineering and medical fields. Some drawbacks of UHMWPE need overcome by radiation processing, such as poor compatibility, creep-resistance and yield strength. In this work, radiation oxidation and grafting were adopted to...
