Ethylene is used in production of fabricated plastics, antifreeze; making fibers; to manufacture ethylene oxide, polyethylene for plastics, alcohol, mustard gas and other organics. It is used to accelerate ripening of fruit; as an anesthetic; and for oxyethylene welding and cutting of metals ...

Ethylene is capable of acting as a ligand as the C=C π bond can donate electron density to an empty metal d orbital, forming a σ bond. A filled metal d orbital is capable of donating electron density into the C=C π antibonding orbital. ...

We also found that H2O2 might be involved in the crosstalk between BRs and ethylene in the tomato response to salt stress. Simultaneously, BR-induced ethylene production was partially blocked by pretreated with a reactive oxygen species scavenger or synthesis inhibitor. These results strongly ...
An ethylene-based polymer composition has been discovered and is characterized by a Comonomer Distribution Constant greater than about 45. The new ethylene-based polymer composition
polymer hostthermal analysisx‐ray analysisinterferometryAbstract In view of the residual crystallinity in PEO found to limit the solubility of some Nd3+‐compounds, amorphous PEO (aPEO) was synthesized for exploration as an alternative host. Complexation, solubility limit, morphology, and response to ...
However, critical questions remain that need further discussions relating to the coherence of animal and human data of experimental data in vitro vs. in vivo and to species-specific dynamics of DNA lesions. 展开 关键词: ethylene oxide carcinogenicity genotoxicity metabolism glutathione transferase DNA ...
