In this paper, we demonstrated that the charge-transfer resistance of photoanode can be calculated through the analysis of its electrochemical impedance spectroscopy (EIS) and the photoelectrocatalytic degradation rate of aniline was inversely proportional to the value of charge-transfer resistance of photoelectrodes prepared by thermally oxidation on titanium. The value of charge-transfer resistance is smaller, the higher its photoelectro-activity is. 展开更多

The mechanical alloying effects on the structures of Fe71.3Al28.4(CeO2)(0.3) and Fe73.3Al9.8-Si-16.6(CeO2)(0.3) samples have been investigated mainly by Mossbauer spectroscopy and X-ray diffraction. it is found that with the increase of milling time, a substituting disordered alpha-Fe solution is formed gradually and almost completed after milled for 72 h. Further increasing milling time causes the atomic rearrangement within the powders. Correspondingly, the average lattice parameter and average crystalline size change until 72 h and remain constant after 72 h. The addition of Si leads to the higher disordered degree reflected in the smaller average hyperfine field and larger mean square deviation. 展开更多

MICROSTRUCTURE sequence series and sedimentary units of tidal flat sediments are commonly used for discrimination of tidal flat facies, flat sequcences and flat features. In this note, the present-day wide coastal muddy tidal flat and recent sub-tidal flat profile are systematically studied based on the correlations between the sediment magnetic fabric parameters and the sedimentary dynamic environment. The variations in the sediment magnetic fabric 展开更多
