Electron Beam Irradiation of Cellulosic Materials—Opportunities and Limitations
The irradiation of pulp is of interest from different perspectives. Mainly it is required when a modification of cellulose is needed. Irradiation could bring many advantages, such as chemical savings and, therefore, cost savings and a reduction in environmental pollutants. In this account, pulp and dissociated celluloses were analyzed before and after irradiation by electron beaming. The focus ...
متن کاملElectron Beam Irradiation Applications
The irradiation of materials with electron beams or X rays is used extensively to enhance or modify their physical, chemical or biological properties. These electron beam “irradiators” cover a very wide range of accelerators technology, beam current and energies to produce a wide variety of products, mostly with polymers. They also are used for curing ink, coatings, and adhesives as well as for...
متن کاملTreatment of Synthetic Textile Wastewater by Combination of Coagulation/Flocculation Process and Electron Beam Irradiation
Introduction: Textile wastewaters from dyeing and finishing processes are heavily polluted with dyes, textile auxiliaries and chemicals and have a broad range of pH, high COD concentration and suspended particles. In this study, the efficiency of color and turbidity removal from synthetic textile wastewater samples were investigated by combined process of coagulation/ flocculation and electron ...
متن کاملElectron beam irradiation of dental composites.
OBJECTIVES Electron beam irradiation can be used to influence the mechanical properties of polymers. It was the aim of this study to investigate whether dental composites can benefit from irradiation in order to achieve increased fracture toughness, work of fracture, hardness or less wear. METHODS Two hundred rectangular specimens of five veneering composites were electron beam irradiated wit...
متن کاملLimitations of Electron Beam Conditioning for Free-Electron Lasers
Several ideas have been proposed to ‘condition’ an electron beam prior to the undulator of a Free-Electron Laser (FEL) by increasing each particle’s energy in proportion to the square of its transverse betatron amplitude. This conditioning enhances FEL gain by reducing the axial velocity spread within the electron bunch. We demonstrate that for symplectic beamlines, and independent of the metho...
