review opportunity. Journal: Corrosion Science
ABSTRACT:
The possibility of using newly synthesize N,N?-bis(4-hydroxybenzaldehyde)-1
,2-cyclohexan diimine (4-HBC) Schiff base as a corrosion inhibitor of API 5L
steel in 1 M HCl solution was investigated by polarization curves, AC
impedance measurements, current transient and SEM and AFM techniques. It
was shown that the inhibition effectiveness increases with an increase in
the concentration of 4-HBC and a de... 阅读全帖 |

a palladium-diimine catalyst catalyze ethylene polymerization.
利用late transition metal的b-elimination, hydride addition 实现chain walking
process.
通过调节气压改变的chain-walking 和polymer chain propagation
的速度从而实现tuning
polyethylene topology with pressure which can form linear PE to Dendritic PE.
It is very promising to make dendrimer by simple conventional polymerizaiton
method instead of tedious multi-step synthesis. |
