Study on the electron beam irradiation color change induction of spodumene (LiAlSi2O6) samples, which color exhibit green, pink and colorless. Characteristic the electron-beam irradiation dose were selected 30,000 kGy, 40,000 kGy and 50,000 kGy. The color and fading of spodumene samples were analyzed by UV-VIS spectrophotometer , crystal structure were determined by X-ray diffraction (XRD) spectrometer, free radical species of impurities were determined by Electron Spin Resonance (ESR) spectrometer before and after irradiation. The results revealed the color of spodumene samples changed after irradiation, from green spodumene became a little darker color, pink spodumene became green color, colorless spodumene became pink to purple color the results of the color analysis and fading displayed on the CIE L* a* b* color system, color change spodumene samples were determined by values changed of a* and b*. Color fade of spodumene were determined by values changed of L*. The results of all samples crystal structure analysis were shown on the XRD patterns of the JCPDS No. 89-6662 (Spodumene) with monoclinic structure. The radical analysis results of impurity elements, green and pink only appear the ESR pattern of manganese (Mn2+), and chromium (Cr3+), respectively. It can be conclusion that intensity of color change depend on the irradiation dose and impurity elements in spodumene samples.

Surface Microstructures

Cr layer was fabricated on 40Cr steel by electric brush plating process and then treated by high current pulsed electron beam irradiation technique. Surface microstructures of specimens before and after the irradiation were investigated. Results show that Cr surface is composed of uniformly distributed small nodule units which are composed of fine Cr particles smaller than 100nm. After high current pulsed electron beam treatment, many cracks are found on surface. The main reason is possibly due to the quasi-static thermal stresses accumulated along the surface of the specimens during the electron beam treatment. The surface grain grow from Cr particles because of heating by electron beam, and their size is less than 200nm.

Structural Tests

The paper presents changes in UHMWPE morphology and structure caused by irradiation with an electron beam and plastic deformation. The input material consisted of two grades of polyethylene, i.e. GUR 1050 and GUR 1020 (Poly Hi Solidur Medi TECH), used for producing the bearing components of endoprostheses applied in total joint alloplasty. Tests involved three groups of samples: the ones subjected to modification through radiation (N) only, those modified by plastic deformation before (ON) and after (NO) irradiation with an electron beam (N). The obtained variants were subjected to comprehensive morphological and structural tests, which made it possible to document changes in the lamellar structure (SEM) and orientation of the crystalline structure (SAXS) as well as to determine the content of the crystalline phase (DSC) and to define crosslinking density.

Here we investigate the osteogenesis and synostosis processes on the surface-modified TiO2nanotubes via electron beam irradiation. The TiO2nanotubes studied were synthesized by anodization process under different anodizing voltage. For the anodization voltage of 15, 20, and 25 V, TiO2nanotubes with diameters of 59, 82, and 105 nm and length of 115, 276, and 310 nm were obtained, respectively. MC3T3-E1 osteoblast cell line was incubated on the TiO2nanotubes to monitor the change in the cell adhesion before and after the electron beam irradiation. We observe that the electron beam irradiation affects the number of surviving osteoblast cells as well as the cultivation time. In particular, the high adhesion rate of 155% was obtained when the osteoblast cells were cultivated for 2 hours on the TiO2nanotube, anodized under 20 V, and irradiated with 5,000 kGy of electron beam.

Vietnamese graphite powder was irradiated by electron beam radiation (EB) at a range of dose from 0 to 120 kGy, then the graphite samples were expanded with a mixture of H2O2:H2SO4 (1,4:20, v/v) incorporating microwave treatment at 700 W for 30 seconds. The characteristic properties of graphite before and after expansion were evaluated by methods of FTIR, Raman, SEM and XRD. Besides the self-assembled of the graphite’s structure after irradiation, the electron beam radiation also facilitated intercalation processing to make expanded graphite, with coefficient of expansion (Kv) 35% higher than that of pristine graphite.
