Carbon nanotubes (CNTs)-templated metal phthalocyanines (MPc) (M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II)) assemblies (CNTs-CONH-MPc) were synthesized and characterized by IR, XRD, SEM, XPS. The lithium-thionyl chloride (Li/SOCl2) cells using CNTs-CONH-MPc as catalysts showed excellent performance, which the capacities increased by 15.44-88.49%, and the initial voltages improved to 3.09-3.22 V. The sequence of the electrochemical catalytic performance of CNTs-CONH-MPc was ranked by central metal ion: Co > Ni > Mn > Fe > Cu > Zn. Based on cyclic voltammetry measurements, the reasonable mechanism is proposed and the role of catalyst is verified. The modified CNTs by MPc greatly promoted the electronic transmission, which significantly improved the performance and the initial voltage of Li/SOCl2 battery. [ABSTRACT FROM AUTHOR]

In this paper the elastic properties of SiOx film are investigated quantitatively for local fixed point and qualitatively for overall area by atomic force acoustic microscopy (AFAM) in which the sample is vibrated at the ultrasonic frequency while the sample surface is touched and scanned with the tip contacting the sample respectively for fixed point and continuous measurements. The SiOx films on the silicon wafers are prepared by the plasma enhanced chemical vapour deposition (PECVD). The local contact stiffness of the tip-SiOx film is calculated from the contact resonance spectrum measured with the atomic force acoustic microscopy. Using the reference approach, indentation modulus of SiOx film for fixed point is obtained. The images of cantilever amplitude are also visualized and analysed when the SiOx surface is excited at a fixed frequency. The results show that the acoustic amplitude images can reflect the elastic properties of the sample. [ABSTRACT FROM AUTHOR]
