National Office of Measures, Budapest, Hungaiy A new method for the absolute determination of electrolytic Conductivity based on direct current and potcntiomctrlc measurements is described. The unique design of the cell uses a removable center section whose length and crosS'Seciional area arc accurately known. Two pairs of matched Ag, AgCI electrodes are used in a four terminal mode of resistan...

Eight new complexes of Cu(II), Co(II), Ni(II) and Zn(II) with isonicotinic acid hydrazide (isoniazid, (INH)) and isonicotinic acid (1-naphthylmethylene)hydrazide (INNMH), having the formula of the type [M(INH)(ac)2] or [M(INNMH)(ac)2] (M = Co(II), Ni(II) and Zn(II)) and [Cu(INH)(ac)2]2, [Cu(INNMH)(ac)2]2, were synthesized and characterized. All complexes were characterized based on elemental an...

The electrodynamic response of DNA in the millimeter wave range is investigated. By performing measurements under a wide range of humidity conditions and comparing the response of single-stranded DNA and double-stranded DNA, we show that the appreciable ac conductivity of DNA is not due to photon-assisted hopping between localized states but is instead due to dissipation from dipole motion in t...

This paper aimed to investigate the electrical characteristics of thin films formed polyethylene oxide (PEO) distributed with dopants containing a fixed quantity iodine (0.1 wt.%). The alternating current (AC) properties were studied using AC impedance technique in frequency range 3kHz–5MHz and temperature 30–55oC. electrically prepared made casting procedure. compared variation conductivity fo...
