Processes Induced in DLC/Polyimide Structures by Irradiation with 60Co ?-Rays
نویسندگان
چکیده
The DLC/Kapton structures irradiated with 60Co ?-rays at doses to 1 MGy have been studied by measuring transmission and attenuated total reflection (ATR) spectra. It has shown that there are significant changes in the spectra ranges of vibrations ?–?, CH2, CH3 bonds due radiation-induced processes byproducts polyimide synthesis residual solvents. Significant differences were found occurring bulk near-surface region a film DLC/polyimide structures. After irradiation, exhibited bands asymmetric symmetric group. Bands associated CH2 group additionally observed region. formation groups layer under irradiation was more pronounced than films; this additional supply hydrogen from DLC film.

The sterile insect technique (SIT) may reduce pest populations by allowing sufficient amount of irradiation-induced sterile males to mate with wild females whilst maintaining mating ability comparable to wild males. Although the SIT methods are well understood, the optimal sterilizing dose and processing development stage for application vary among species. To ensure effective pest control prog...
متن کاملIdentification of Novel Chromosomal Aberrations Induced by 60Co-γ-Irradiation in Wheat-Dasypyrum villosum Lines
Mutations induced by radiation are widely used for developing new varieties of plants. To better understand the frequency and pattern of irradiation-induced chromosomal rearrangements, we irradiated the dry seeds of Chinese Spring (CS)-Dasypyrum villosum nullisomic-tetrasomic (6A/6D) addition (6V) line (2n = 44), WD14, with (60)Co-γ-rays at dosages of 100, 200, and 300 Gy. The M₀ and M₁ generat...
متن کاملInduced Magnetic Order by Ion Irradiation of Carbon-Based Structures
Irradiation effects in graphite were one major research area in the past, partially due to its application as a moderator in thermal nuclear reactors. Graphite is still a material of choice for nuclear applications due to its low cross-section for neutron absorption. The influence of irradiation damage produced by different kinds of ions on several properties of graphite was reviewed by Kelly (...
متن کاملPlant regeneration of Korean wild ginseng (Panax ginseng Meyer) mutant lines induced by γ-irradiation (60Co) of adventitious roots
An efficient in vitro protocol has been established for somatic embryogenesis and plantlet conversion of Korean wild ginseng (Panax ginseng Meyer). Wild-type and mutant adventitious roots derived from the ginseng produced calluses on Murashige and Skoog (MS) medium supplemented with 0.5 mg/L 2,4-dichlorophenoxyacetic acid and 0.3 mg/L kinetin; 53.3% of the explants formed callus. Embryogenic ca...

Flow cytometry analysis was used to detect the changes of γH2AX protein expression in human peripheral blood lymphocytes. In the dose-effect study, the expression of γH2AX was detected 1 h after irradiation with 60Co γ-rays at doses of 0, 0.5, 1, 2, 4, and 6 Gy. Blood was cultivated for 0, 1, 2, 4, 6, 12, and 24 h after 4 Gy 60Co γ-rays irradiation for the time-effect study. At the same time, t...
