The effects of amination time and temperature, the compositions of amination medium on membrane stability and ion-exchange capacity (IEC) are reported in this paper. It is revealed that themembrane’s ...
Chemical cross-linking anion exchange series membranes were prepared from linear engineering plastics poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) by conducting the processes of bromination and aminat...
In this paper, a new series of anion exchange membranes have been produced from linear engineering plastics poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) by conducting the processes of bromination, chl...
Let g,1 be a compact oriented surface of genus g with one boundary component,andMg,1 its mapping class group. Morita showed that the image of the k-th Johnson homomorphism M k of Mg,1 is contained ...
Let H(2)n denote the second-order harmonic numberP0n 1/k2 for n = 0, 1, 2, . . . . In this paper we obtain the following new identity for 3: 1 X k=1 2kH(2) k−1 k􀀀2k k = 3 48 .We e...
A series of 5-aryl-1,3,4-oxadiazole-2-thiols was found to inhibit trans-cinnamate 4-hydroxylase (C4H) from Populus kitakamiensis, which was expressed in yeast. 5-Phenyl-1,3,4-oxadiazole-2-thiol show...
