A new cyclic peptide named polycarponin A, was isolated from the whole plants of Polycarpon prostratum. Its structure was determined by detailed spectroscopic a
With a Ni/GC ion implantation modified electrode as working electrode, in 0.1 mol/L HOAc-NaOAc (pH=4.62) solution, a sensitive reductive wave of ADM was obtaine
In this paper a pH microprobe technique was developed to measure in-situ the pH value at the electrode/solution interface. Iridium oxide was used as a pH sensit
