Nonenzymatic Glucose Electrochemical Oxidation Based on Pt Decorated MWCNTs-PVA Hybrid Electrode

Advanced materials research (2015)

Shu Min Liu Yu Zheng Li Ying Cui Chang Zhao Xiao Yu

The multi-walled carbon nanotubes (MWCNTs) /polyvinyl alcohol (PVA) coating may have excellent biocompatibility and unique electrical properties. The effect of the dispersing agent on the electrochemical behaviors is very relevant,which has a great influence on the ionic conductivity of the composite material.We prepared four membrane electrodes of MWCNTs by using two dispersing processes of electrophoretic deposition (EPD). The scanning electron microscope (SEM) graphs of the MWCNTs/PVA composite were recorded In the NaOH solution, glucose is electrochemically oxidized on the acidified-MWCNTs/ PVA composite coating with high current density. The MWCNTs of the covalent dispersing methods treatment have a positive influence for the oxidation of glucose. The PVA can strengthen the dispersion effect of CTAB-MWCNTs for the EDP. The cooperative electrocatalytic property of MWCNTs-Pt toward glucose is not impaired by the association with the PVA binder.

Tensile Properties of Low Nickel Austenitic Stainless Steel at Elevated Temperatures

Applied Mechanics and Materials (2012)

Shu Min Liu Jian Bin Zhang

The elevated temperature short-time tensile test with the sample of casting low nickel stainless steel was conducted on SHIMADZU AG-10 at ten temperatures 300, 500, 600, 700, 800, 950, 1000, 1050, 1100, and 1250°C, respectively. The stress-strain curves with the thermal deformation at the different temperatures, the peak stress intensity-temperature curve, and the reduction percentage of cross sectional area-temperature curve were obtained. Metallographic test samples were prepared and the morphology of deforming zone was observed by optical microscopy. The experimental results show that the tensile strength of the test samples decreases with increasing temperature. From 300 to 800°C, the work harding occurred and the tensile strength increases with increasing strain. The work softening occurred and the tensile strength decreases with increasing strain at temperatures of 800 to 1250°C. The minimum value of reduction percentage was measured at 800 °C. The austenite and delta-ferrite are the main phase in the tested samples. When the tensile temperatures are increased to 1200°C, the delta-ferrite became thinner and broke down to be spheroidized.
