Validity Of The Independent-Particle Approximation In X-Ray Photoemission: The Exception, Not The Rule, D. Hansen, Oliver Hemmers, H. Wang, Dennis W. Lindle, P. Focke, I. A. Sellin, Clemens Heske, H. S. Chakraborty, P. C. Deshmukh, S. T. Manson
Environmental Studies Faculty Publications
A combined experimental and theoretical study of argon valence photoionization illustrates the discovery of the broad lack of validity of the independent-particle approximation (IPA) for x-ray photoemission. In addition to previously known breakdowns of the IPA, which are limited to high photon energies and regions very near threshold, the observed breakdown in photoionization at intermediate energies demonstrates generally that the IPA is valid only in very restricted domains. These restrictions are expected to be relevant throughout the periodic table, with consequences for a wide variety of applications.

A New Method For Preparing Self-Assembled Lipid Bilayers On Pt Electrode, Peng Diao, Dian-Lu Jiang, Xiao-Li Cui, Deng-Ping Gu, Ru-Ting Tong
Journal of Electrochemistry
A new method for preparing Pt-supported bilayer lipid membrane (Pt-BLM) on Pt electrode cleaned by high power ultrasound was reported. The reported method was convenient, costing less platinum and could be used to form large-area Pt-BLM as compared with the traditional Pt-wire-cutting method. The electrical properties of Pt-BLM were studied using electrochemical impedance spectroscopy and cyclic voltammetry. Experimental results showed that the values of membrane capacitance and the voltammetric characteristics were consistent with those of Pt-BLM prepared by traditional method.

Deactivation Of Nickel Oxide/Hydroxide To Electrooxidation Of H2Po2 Anions On Nickel Electrodes In Alkaline Solutions, Tai-Xiang Jiang, Hui-Huang Wu
Deactivation Of Nickel Oxide/Hydroxide To Electrooxidation Of H2Po2 Anions On Nickel Electrodes In Alkaline Solutions, Tai-Xiang Jiang, Hui-Huang Wu
Journal of Electrochemistry
Electrooxidation of hypophosphite anions on polycrystalline nickel in alkaline solutions has been investigated by cyclic voltammetry and open circuit potential measurements. The results are explained based on the mechanism that the first step of hypophosphite oxidation is the adsorption of hypophosphite ions on nickel, followed by the homolysis of its hydrogen bond with the formation of radicals. The oxidation of hypophosphite on nickel in alkaline medium occurs at lower potentials between ca. -0.8 V— -1.1 V (SCE) and phosphite ion is the only oxidation product. There is no indication of hypophosphite oxidation at higher potentials. Severe deactivation of the surface …

Journal of Electrochemistry
This work contains two parts: (1) A charge curve equation having no appro-ximation for passivated metal corrosion systems is derived and compared with the routine charge curve equation, which is virtual only when the polarization is minim(linear range). (2) It is simpler to analyze charge curve data by from of charge differential equation than from charge curve equation. After the charge curve data are measured, the slope of charge curve is computed by numerical differentiation method, then the charge differential equation may be transformed to a set of linear equations using polynomial approximation.

Effects Of The Surfactant And Ph On Linear Potential Scan Of Aqueous Na2S Solution, Qing-Feng Yi, Qi-Yuan Chen, Ping-Min Zhang
Journal of Electrochemistry
In presence of a cationic surfactant HTAB,linear potential scans for Na2S at graphite anode in both saturated sodium tetra-borate solution and 1 mol·L-1 NaOH solution, have been investigated. Results show that anodic current density increases and peak potentials shift to more negative with the increase of HTAB concentrations. The anodic current densities increased by addition of HTAB are larger in 1 mol·L-1 NaOH than those in saturated sodium tetra-borate solution, resulting from different acting forces of HTAB with various charged electro-active species. Both oxidation and reduction peaks in cyclic voltammograms for Na2S containing solution …

Journal of Electrochemistry
Li2+xGdxSi1-xO3(x =0～0.15) samples have been prepared by the Sol-Gel method. The power samples were characterized by DTA-TG, XRD and TEM. Ionic conductivity of the sinter was determined by means of A-C impedance measurements. The experimental results showed that the range of solid-solution was 0 < x ≤ 0.09, while the conductivity of samples raised with increasing amount of Gd2O3 added, and average grain size of samples was 80 nm. In comparing with the samples by the conventional solid state reaction, the samples prepared by Sol-Gel method required lower temperature and presented higher ionic conductivity.

The Influence Of Heat On The Measurement Of Photocurrent At The Anodic Film Of Nickel Electrode, Hang Chen, Zhi-Yu Jiang
Journal of Electrochemistry
The influence of heat on the measurement of photocurrent for nickel electrode in 1 mol/L NaOH solution was investigated by using the photocurrent, photothermal and thermal current methods. It was found that the appearance of photocurrent in potential region of -0.75~0.20 V (vs. Hg/HgO electrode) was due to the p-type semiconductor properties of Ni(OH)2 film in which is agree with the previous report. In the Ni(OH)2/NiOOH redox potential region, the increase of temperature at the surface of working electrode during irradiation significantly promoted the electrochemical reaction strongly. The photocurrent observed in potential region 0.20~0.57 V is mainly …

Journal of Electrochemistry
The tribocorrosion process of Fe-Cr alloys with different Cr content in H2SO4 solution was investigated. The influence of applied load, friction velocity, Cr content and concentration of H2SO4 in solution on the triboelectrochemical behaviors of the alloys was analyzed. It is shown that applied load and friction velocity have singnificant influence on the tribocurrent density in passive region when friction process occurs on part of the surface of alloy. Increasing the corrosion resistance of alloys or decreasing the aggressive of the solution can reduce the alloy removal velocity.

A Study On The Cathode Protection Potential Against Pitting Corrosion, Chun-Chun Xu, You-Ping Liu, Xiao-Bo Zhang, Xu-Hui Zhao
Journal of Electrochemistry
The methods have been developed to determine the protection potential against pitting corrosion. They are based on the theory that the pitting protection potential (Ep) is actually the transition potential of the direction of current between the occluded cell and the external surface (ET). ET lasts from -220 mV to -440 mV (SCE), the lowest of which can be considered as cathode protection potential. The Ep values determined with cyclic potentiodynamic polarization method is included in the ET with above methods.
