The Difference Of The Geometrical Thickness And The Electrochemical Apparent Effective Thickness Of Self-Assembled Monolayers, Xiao-Li Cui, Jun-Xin Li, Ru-Ting Tong
The Difference Of The Geometrical Thickness And The Electrochemical Apparent Effective Thickness Of Self-Assembled Monolayers, Xiao-Li Cui, Jun-Xin Li, Ru-Ting Tong
Journal of Electrochemistry
The geometrical thickness, which was obtained from the capacitance of membrane, can be used to characterize the existence of membrane. The apparent effective thickness, which is analyzed from the electron transfer constant of transmembrane, can be used to determine the degree of “collapsed" of molecules. Though the two thicknesses were different in value, there was no contradiction. The influence on the geometrical thickness is little, but the effect to the apparent effective thickness is great from the small “collapsed" area in the membrane from the given calculation.

Effect Of High Concentration Lithium Bromide Solution On Electrochemical Behavior Of Low Alloy Steel At High Temperature, Jian-Wei Guo, Cheng-Hao Liang
Journal of Electrochemistry
By electrochemical measurements and weight loss experiments, the effect of MoO42- on low alloy steel's electrochemical behaviors was investigated at high temperature in 55%LiBr+0.07 mol/L LiOH solution. The results showed that MoO42-, as an anodic inhibitor, formed passive film rapidly and impeded both anodic and cathodic procedures. Moreover, Na2MoO4 prevented corrosion effectively in 55%LiBr+0.07 mol/L LiOH solution when its concentration is more than 200 mg/L. The pitting potential increased accompanying to the arising of Na2MoO4 concentration. Some elements of alloy strengthened resistance to corrosion, shch as chromium and nickel, …

Journal of Electrochemistry
High over-potential of proton exchange membrane fuel cell (PEMFC) anode caused by carbon monnoxide poisoning when reformate or methanol is used as fuel is main obstacle to the high performance of PEMFCs. Using carbon monoxide tolerant catalysts is the most hopeful way to solve the CO problem. The CO poisoning problem is reviewed briefly in this paper, and the development of CO tolerant catalysts is introduced in details, including electrocatalysts activity, preparation method and mechanism of tolerance to CO.Mo and W can improve catalysts' CO tolerance. Multi-component catalysts are expected to be more tolerant to CO.

Studies Of Adsorption And Oxidation Of Ethanol On Nm-Pt/Gc Electrode——I. Cyclic Voltammograms And In-Situ Ftir Spectroscopy In Alkaline Media, Guo-Lian Chen, Shi-Gang Sun, Sheng-Pei Chen, Zhi-You Zhou
Journal of Electrochemistry
The electro-oxidation of ethanol on nm-Pt/GC electrode in alkaline solutions containing 0.02 mol·L-1 NaOH+0.1 mol·L-1 CH3CH2OH was investigated by using cyclic voltammetry and in-situ FTIR spectroscopy. The experimental results demonstrated that the main product of ethanol oxidation is CH3COO-, only very small amount of CH 3CHO has been determined simultaneously. In contrast with the dual path reaction mechanism for the oxidation of ethanol in acid media, the oxidation of ethanol in alkaline media didn't pass through the dissociative adsorption, and no adsorbed species could be determined even using a …

The Memory Effect Of Mh-Ni Battery, De-Ming Xie, Jian-Ming Wang, Jian-Qing Zhang, Chu-Nan Cao
Journal of Electrochemistry
The memory effect of MH-Ni battery was investigated. The depth of discharge, discharge rate and cycle number influence the memory effect greatly. A few completely full charge/discharge cycles could eliminate it. The existence of the memory effect had nothing to do with zinc element. During the course of life cycling at low DOD (degree of discharge), the smaller the discharge current was, the lower was the maximum charge voltage. In addition, discharge voltage and discharge capacity drop fast at the beginning, gradually leveled off at about a value. If the discharge current was increased, the discharge capacity was obviously less …

An angular analysis of B0 → J/ψK*0and Bs0 → J/ψφ has been used to determine the decay amplitudes with parity-even longitudinal (A0) and transverse (A║) polarization and parity-odd transverse (A┴) polarization. The measurements are based on 190 B0 and 40Bs0candidates obtained from 89 pb-1 of p̅p collisions at the Fermilab Tevatron. The longitudinal decay amplitude dominates with |A0|2= 0.59 ± 0.06 ± 0.01 for B0 and |A0|2 …

Magnetic Clusters On Single-Walled Carbon Nanotubes: The Kondo Effect In A One-Dimensional Host, Teri W. Odom, Jin-Lin Huang, Chin Li Cheung, Charles M. Lieber
Barry Chin Li Cheung Publications
Single-walled carbon nanotubes are ideal systems for investigating fundamental properties and applications of one-dimensional electronic systems. The interaction of magnetic impurities with electrons confined in one dimension has been studied by spatially resolving the local electronic density of states of small cobalt clusters on metallic single-walled nanotubes with a low-temperature scanning tunneling microscope. Spectroscopic measurements performed on and near these clusters exhibit a narrow peak near the Fermi level that has been identified as a Kondo resonance. Using the scanning tunneling microscope to fabricate ultra-small magnetic nanostructures consisting of small cobalt clusters on short nanotube pieces, spectroscopic studies of this …
