The cross-linked imidazolium functionalized anion-exchange membranes is in-situ prepared via reaction of chloromethylated poly(styrene-b-isobutylene-b-styrene) with 1,1’-(1,6-hexanediyl)bisimidazole and N-methylimidazole. composite a small amount modified graphene oxide grafted octadecyl propyl phenyl could be further prepared. These exhibit significantly high chemical stability ionic conductiv...

Formation of spatially periodic patterns is a ubiquitous process in nature and man-made systems. Periodic precipitation the oldest type pattern formation, which formed colloid particles are self-assembled into sequence separated zones solid hydrogels. Chemical systems exhibiting mostly comprise oppositely charged inorganic ions. Here, we present new sub-group this phenomenon driven by diffusion...

For the first time, repeatable self-healing was achieved in a cross-linked epoxy polymer by incorporating 2-ethyl-4-methylimidazole (24-EMI) into the matrix as a latent polymerization initiator. Upon material damage and infiltration of liquid EPON 8132 epoxy monomer healing agent into the crack plane, polymerization occurs in the damaged region with a moderate application of heat in the presenc...

A new activator for the coupling of phosphoramidites to the 5'-hydroxyl group during oligonucleotide synthesis is introduced. The observed time to complete coupling is twice as fast with 4, 5-dicyanoimidazole (DCI) as the activator, compared with 1 H -tetrazole. The effectiveness of DCI is thought to be based on its nucleophilicity. DCI is soluble in acetonitrile up to 1.1 M at room temperature...

The partition coefficients, Kmim, of N-methylimidazole (mim) in two-component systems composed of ionic liquid (IL) and a series of organic solvents immiscible with ILs (butyl acetate, ethyl acetate, tert-butyl methyl ether, diethyl ether and cyclohexane) were determined by a shake-flask method. The influence of different factors such as temperature, solvent polarity, mim concentration, and wat...
