The electrochemical corrosion of bulk nanocrystalline ingot iron in acidic sulfate solution

Article Abstract:

The corrosion properties of bulk nanocrystalline ingot iron (BNII) fabricated from conventional polycrystalline ingot iron (CPII) by severe rolling were investigated by means of immersion test, potentiodynamic polarization (PDP), electrochemical impedence spectroscopy (EIS) tests and scanning electron microscopy (SEM) observations. The results indicated that BNII possesses excellent corrosion resistance in comparison with CPII in acidic sulfate solution at room temperature.

Electrode independent chemoresistive response for cobalt phthalocyanine in the space charge limited conductivity regime

Article Abstract:

A study is conducted on the electrical properties of thick metallophthalocyanine films prepared by organic molecular beam epitaxy (OMBE) on interdigitated electrodes with DC current-voltage measurements and impedence spectroscopy. The transition from Ohmic behavior at low voltages to space-charge-limited conductivity (SCLC) at higher voltages depends on the metal electrode but does not correlate with the work function of the electrode.

Thermodynamic characterization of rare earth salts of strong polyacid copolymers

Article Abstract:

Stoichiometric La3+, Ce3+, and Nd3+ salts of poly[(vinyl alcohol)-co(vinyl sulfate)] (PVAS) copolymer polyacids are studied in aqueous solution without added salt. It was seen that all the LnPVAS salts were totally water soluble in composition and concentration range.
