Incorporation of carbon nanotubes (CNTs) into such functional devices as transistors, sensors and field emitters requires a control over their placement on substrate surfaces. In this paper, horizontal arrays of multi-walled carbon nanotubes (MWNTs) have been assembled on silicon substrate surfaces using a gas flow method. The influences of the flow rate and the flow time on the alignment of the MWNTs...
Nanocrystalline LiMn 2 O 4 spinel was successfully prepared at the temperature as low as 200°C via solution combustion method, employing lithium acetate and manganese acetate as Li–Mn source, citric acid as chelating and combusting agent. The XRD patterns show it is a reaction-controlled process. And the morphology was investigated by transmission electron microscope (TEM) images and...
