On-line ion-exchange separation and preconcentration were combined with flow-injection hydride generation atomic absorption spectrometry (HGAAS) to determine ultr
Under the condition of solid-liquid phase transfer catalysis,olefins were obtained by the reaction of p-nitrobenzyldibutyltelluroniumbromide with aromatic aldeh
The structures of Nylon-1010 with different draw ratios have been investigated by using Small-AngleX-ray Scattering(SAXS).It is shown that by using a simple geo
The asymmetric alkylations of chiral transition metal complexes derived from(+)-camphor and 2-aminomethyl-6-methylpyridine were examined under mildconditions.Th
A new solvent polymeric membrane (SPM)pH2sensor based on 4,4’-bis (N, N-didecylamino)methyl)azobenzene as neutral carricr has been reported. It has excellent p
